Vehicle concept
The new R 172 is now the third generation of this vehicle, which is designed to continue the success story of the 2-seater compact roadster with model designation SLK from Mercedes-Benz. The basic concept of an open-top, sporty-dynamic vehicle with lifestyle-oriented characteristics remains intact. The vehicle is designed to be strong, lively and cultivated with an overriding focus on driving pleasure and roadster enjoyment.
Innovations
• Panoramic Vario roof with MAGIC SKY CONTROL • LED rear lamps • New generation 6-cylinder gasoline engine M 276 E35 • Ambiance illumination in interior • Transparent pivoting draft stop (AIRGUIDE) • Seats and interior equipment with sun-reflective leather • Electrically operated parking brake
Dimensional concept
The combination of the length and large width of the vehicle give the new SLK the typical proportions of a roadster. However, the new generation of the SLK (R 172) is significantly longer (+31 mm) and wider (+33 mm) than its predecessor (R 171).
Highlights
• • • • • • Large and easily usable trunk KEYLESS GO Attention assistance system (ATTENTION ASSIST) DISTRONIC PLUS incl. BAS PLUS and PRE-SAFE® brake Intelligent Light System Vehicle dynamics package, suspension with adjustable damping, Torque Vectoring Brake and direct steering Speed Limit Assist ECO start/stop function Parking assistance

Front view
The upright radiator grille forms the basis for a long and well-proportioned engine hood. In addition, the contour edges stretching out towards the rear also contribute to an impressively dynamic appearance. Together with the exposed star and distinctively contoured slat with frontal chrome-plating, the width of the radiator grille allows the vehicle to sit confidently on the road. The engine hood ends at the air inlet grilles, each of which is accentuated by three slats. The "soft nose" front end is a new feature with its distinct tapering and large air intakes. Incorporating a plastic bumper and aluminum engine hood, the soft nose meets the relevant legal requirements in the area of pedestrian protection. The frontal appearance is also dependent on the illumination system installed on the vehicle: on the basic version with single-tube H7 headlamps, the bumper houses round LED daytime running lights and front fog lamps with chrome-plated trim. In the optional version with Intelligent Light System, the main headlamps feature a dual-tube design and the horizontal daytime running lights in the bumper each incorporate four LEDs.

Side view
Viewing the vehicle from the side, the character line extending from the fender grilles harmoniously breaks up the proportions of the vehicle, giving the SLK a highly dynamic look. The grilles have a matching design to those of the engine hood and are rounded off by a chrome-plated horizontal fin. The contour edge extending from the door/shoulder additionally emphasizes the masculine shaping of the rear fender. With the proportions of the long engine hood, short rear end and outside mirrors installed on the beltline, the side view of the SLK clearly lives up to the sports car ideal. The same is true with the roof open or closed.

Rear view
The exterior design of the vehicle is rounded off by the rear end. The explicit goal of the design team was, as with the front end, to emphasize the width and powerful appearance of the vehicle. This goal was achieved through horizontal accentuation of the rear lamps and an upper outline which runs towards the front at the sides. The powerful look of the rear end is also emphasized by the twin-pipe exhaust system, which is capped off with trapezoidal exhaust tips.

Pivoting draft stop (AIRGUIDE)
There are two alternative draft stop concepts to ensure that the interior compartment is kept comfortably free of drafts with the Vario roof open and side windows up. The concept of the "pivoting draft stop" is completely new to the R 172. It has both an active and inactive position which can be adjusted without any need for assembly or disassembly. If desired, it can be put into the active position for just one person. It reduces the air flowing in from behind in the direct vicinity of the passengers and channels it into the unproblematic area between the passengers. The pivoting draft stop also always comes with aluminum rear roll bar shells (part of aluminum package). As an alternative, there is a removable draft stop which is fixed in place between the roll bars and consists of a net in a fixed frame. When not in use, it can be stored compactly in the trunk. If the driver and front passenger would like to experience greater airstream with the Vario roof open, this can easily be achieved by partially or completely lowering the side windows and/or not using the respective draft stop in order to bring about the desired airstream intensity.

Vario roof
As on the predecessor model series, the new SLK is also equipped with a Vario roof as standard. The opening and closing function can also be operated externally using the convenience feature via the infrared remote control in the key. However, a new feature are the three roof variants which the customer can now choose from: • A roof with painted plastic paneling as standard • A panoramic Vario roof as special equipment • As a further special equipment option and the highlight of the roof variants, a panoramic Vario roof with MAGIC SKY CONTROL All variants are manufactured as a magnesium/plastic construction. This reduces the weight of the entire roof module by 30% compared to the predecessor model (R 171). Compared to the predecessor model series, the actuation forces required when opening the trunk lid have been reduced for opening and closing of the Vario roof. New to the R 172 is a 4-link hinge (R 171 had a 7-link hinge) for the opening function. The smaller number of links noticeably reduces the force required to open the trunk lid. In the event of a malfunction, the roof can be manually operated once the pressure has been released via the emergency opening valve. Detailed information can be found in the current WIS documentation.

MAGIC SKY CONTROL
The panoramic Vario roof with MAGIC SKY CONTROL can vary its transparency in two stages. The roof has its minimum transparency (first stage) when the output voltage is 0 V. The maximum transparency (second stage) is reached at 120 V. The MAGIC SKY CONTROL control unit contains a DC/AC converter and operates at an output voltage (AC voltage) of max. U = 140 V at a frequency of max. f = 400 Hz. The MAGIC SKY CONTROL roof is made up of several layers. By applying an AC voltage to a Suspended Particle Device (SPD) layer, the transparency of the glass is changed from opaque to transparent or from transparent to opaque. When transparency is activated, the MAGIC SKY CONTROL control unit actuates the SPD film in the MAGIC SKY CONTROL roof, thus changing the transparency of the film. Since the reaction time of the particles depends on the outside temperature, the voltage can be briefly raised to U = 130 V output voltage. This shortens the reaction time of the particles if the outside temperature is low. Shutting off circuit 15R deactivates the control system and the roof becomes non-transparent. When it is switched back on, the condition before shutoff is restored.

Interior design
The interior of the new SLK-Class is sporty-elegant and consistently reflects the dynamic look of the exterior. The chrome-plated "Silver Shadow" switches and panels, along with the aluminum trim, underline the sporty character of the new roadster. By optimizing the location and function of the instruments, it has been possible to create additional stowage areas and simplify operation of the controls.

Storage and stowage compartments
The interior design of the SLK incorporates a clever stowage concept. In addition to the glove compartment in the instrument panel, there are 3 stowage compartments in the center console and one stowage compartment (or optionally an ashtray) in the front area underneath the AC operating unit. Furthermore, there is a roller blind compartment in front of the armrest next to the hand rest which can optionally be used as a beverage holder. There is also large stowage compartment under the armrest, providing for a wide range of stowage options. There is a net located in the front passenger footwell on the center tunnel. A flexible bottle holder can be ordered for this location as special equipment. On the rear panel located centrally behind the seats is a ruffled pocket for storing CDs or similar items. On the driver side, there is a net on the rear panel for holding the vehicle document wallet.

Instrument panel
In harmony with the exterior design, the instrument panel also features a strong emphasis on horizontal lines, giving the roadster an exemplary and bold design. The four galvanized, high-quality air vents mean that the interior of the SLK also clearly identifies it as a member of the strong stable of Mercedes-Benz sports cars. These also quite deliberately create associations with air travel. The touch-and-feel of the flat-bottomed, 3-spoke sport steering wheel with metallic spoke cover panels, combined with the graphic design of the instrument cluster in the vicinity of the driver, successfully bridges the gap between sportiness on the one hand and cultivated style on the other. In addition to an optional sun sensor and distance indicator for the parking assistant, an analog clock can also be optionally integrated into the centerfill grille of the instrument panel. The 5.8" central display is located between the two center air vents. With the COMAND Online special equipment option, the screen size increases to 7.0".

Instrument cluster
The twin-tube instrument cluster features a display for showing information from the on-board computer located centrally between the two analog dial-type gauges. When the ignition is switched on, the pointers of the speedometer and tachometer move synchronously all the way to the end and then return to the zero position once. The speedometer incorporates the indicator lamps for the ESP® functions (ESP, ESP-OFF), the driving lights, the high beams, the fuel reserve, the electric parking brake function and the anti-lock braking system. Integrated in the tachometer are the warning lamps for the supplemental restraint system (SRS), the seat belts, the tire pressure monitor, engine diagnosis, the coolant temperature as well as the rear fog lamp and front fog lamp functions. Located between the two dial faces in the central display is an indicator for the currently selected gear range and transmission mode on vehicles with automatic transmission. The time and outside temperature are shown here on vehicles with manual transmission.

New technical features
The SLK is based on the tried-and-tested technology of the predecessor model.
Use of NAT2 FE+
Due to development of the NAT2 transmission and the increased durability of the new fluid, the fluid change intervals have changed from a one-off change at 60,000 km (old) to every 125,000 km or 5 years (new).
New engines
The new generation of V-gasoline engines (M 276) supply greater power with lower consumption. For the first time, a diesel engine (OM 651) is being offered for the SLK.
Extended maintenance strategy
As on the predecessor model series, the tried-andtested extended maintenance strategy is also used for the SLK. Both workshops and the customer will benefit from the extended maintenance scopes from the very first kilometer driven. By making maintenance less complicated and introducing the basic service which covers the technically essential items, we are able to offer maintenance that is more cost-efficient and competitive for price-sensitive customers without compromising the usual Mercedes-Benz service quality. As with the current model series, an optional PLUS package is available to supplement both the minor and major basic services to cater for service and convenience-oriented customers. All requirements for maintenance according to manufacturer guidelines are fulfilled both by the basic service and by the service with Plus package.

Engine cooling
General
All engines of the SLK are equipped with a cooling module with cross-flow radiator and, in combination with an automatic transmission, a transmission oil heat exchanger in the right wheel arch. Other components include a condenser with attached refrigerant accumulator and drier and a continuously variable electric suction fan. The cooling system also includes a charge air cooler on the supercharged 4-cylinder engines. This is located ahead of the condenser underneath the crossmember and attached to the radiator. Different radiator block depths and different electric suction fans with power outputs of 400 W and 600 W are employed to ensure that the varying cooling requirements of the various engines and items of equipment are met. The electronic control unit for the electric suction fan is attached to the fan shroud on the 400 W variant and integrated in the electric motor on the 600 W variant. All cooling circuits are filled via an external coolant expansion reservoir. The cap has a 2-stage valve which, when heated, temporarily increases the system pressure to 2 bar to prevent the evaporation of coolant. The air ducting has a two-piece design. The upper air duct is attached to the condenser. The lower air duct is hooked in and clipped to the charge air cooler or directly to the radiator. All components of the cooling module are connected to each other with clips and quick couplings to allow for easy assembly and service access.
Adjustable radiator shutters
Depending on the engine variant and national version, the SLK is equipped with adjustable radiator shutters with which the air flow through the cooling module of the engine and through the engine compartment can be controlled. Shutters consisting of a number of slats are arranged in a circular shape parallel to the fan. Through an actuator attached to the cooling module, the slats can be jointly turned, thus steplessly closing or opening the flow path for the cooling air. One of the most important advantages of adjustable radiator shutters is the positive effect they have on the aerodynamics of the vehicle, which in turn makes a reduction in fuel consumption possible as well as emissions improvements. Other advantages include the fact that the engine reaches its operating temperature more quickly, heating comfort is improved and the engine noise is further dampened with the radiator shutters closed.

Gasoline engine M 271 EVO
Fuel is supplied to the M 271 EVO engine by the lowpressure fuel circuit and high-pressure fuel circuit subsystems. The fuel reaches the high-pressure pump from the tank via the low-pressure fuel circuit. When actuated, the fuel pump draws the fuel out of the fuel feed module and pumps it through the fuel filter to the highpressure pump. The fuel pressure is variably regulated to between 4.0 and 6.7 bar depending on fuel requirements. There is a check valve at the feed point of the fuel filter which prevents reduction of the fuel pressure when the fuel pump is switched off. There is a pressure limiting valve calibrated to 7.5 bar between the filter cartridge and the feed line fitting. The fuel from the fuel tank flows from the low-pressure fuel distributor to the high-pressure pump. This compresses the fuel to max. 120 bar and pumps it to the rail. Here it is stored before it is finely atomized and sprayed into the respective combustion chamber by the fuel injectors. The fuel injectors are supplied with fuel directly from the corresponding rail. There are no return lines on the rails. There is a quantity control valve on the high-pressure pump. This is actuated according to need by the MESFI [ME] control unit via a PWM signal. This allows the fuel quantity which reaches the three pump units to be controlled and the high-pressure fuel pump only compresses the fuel which is required by the engine. The rail pressure is thus regulated from 30 to 140 bar depending on the operating condition of the engine.

Gasoline engine M 276
Fuel is supplied to the M 276 engine by the low-pressure fuel circuit and high-pressure fuel circuit subsystems. The fuel reaches the high-pressure pump from the tank via the low-pressure fuel circuit. When actuated, the fuel pump draws the fuel out of the fuel feed module and pumps it through the fuel filter to the highpressure pump. Depending on the fuel requirement, the fuel pressure is varied from approx. 4.5 to 6.7 bar. In the filter feed line there is a check valve which prevents the fuel pressure from dissipating when the fuel pump is shut off. There is a pressure limiting valve calibrated to 7.5 bar between the filter cartridge and the feed line fitting. The fuel from the fuel tank flows from the low-pressure fuel distributor to the high-pressure pump. This increases the fuel pressure to up to 200 bar (depending on the operating state) and directs it through the high-pressure line and the rails to the fuel injectors. In the high-pressure fuel circuit, the high fuel pressure necessary for jet-guided direct injection is generated, regulated and stored in the rails. The fuel injectors in each cylinder bank are supplied with fuel directly from the corresponding rail. There are no return lines on the rails. The high-pressure pump has a quantity control valve which regulates the fuel quantity supplied to the pump element according to the specified fuel pressure. The fuel pressure and temperature sensor registers the current fuel high pressure (rail pressure) and the fuel temperature in the left rail. The rail pressure is regulated by the ME-SFI [ME] (motor electronics) control unit, which actuates the quantity control valve with a PWM signal until the specified pressure is obtained in the rail.

Diesel engine
Fuel is supplied to the OM 651 diesel engine by the low-pressure fuel circuit and high-pressure fuel circuit subsystems. The fuel reaches the high-pressure pump from the tank via the low-pressure fuel circuit. When actuated, the fuel pump draws the fuel out of the fuel feed module and pumps it through the fuel filter to the highpressure pump. Depending on the fuel requirements, the fuel pressure is regulated to approx. 3.0 – 5.0 bar. In addition, the quantity control valve regulates the flow of fuel to the high-pressure pump in order to keep its temperature low. In the high-pressure fuel circuit, the fuel is pumped by the high-pressure pump into the rail depending on the accelerator pedal signal, engine speed and fuel temperature. The fuel reaches the fuel injectors from the rail via the high-pressure lines. Based on a performance map, the CDI control unit calculates the cylinder-selective injection quantity for the respective operating condition. This is dependent on the fuel pressure in the rail and the actuation duration of the fuel injectors. The fuel pressure in the rail is controlled by the pressure regulating valve and the quantity control valve. The actual fuel pressure present in the rail is recorded by the rail pressure sensor and continuously forwarded to the CDI control unit. Fuel preheating The fuel preheating system heating element is integrated in the fuel main filter in order to ensure flowability of the fuel at low outside temperatures. This does not apply to vehicles with (Code U41) Fuel/ water separator and lubrication package. These vehicles feature a fuel filter condensation sensor with heating element for water level monitoring. The heating element is energized by the glow output stage and warms up the fuel in the fuel filter. The current condensation level is transmitted to the CDI control unit via the fuel filter condensation sensor. As of a condensation level of approx. 100 ml, the CDI control unit transmits a message via chassis CAN to the instrument cluster, which displays this on the multifunction display as a warning message.

The exhaust system of the M 271 EVO consists of a firewall catalytic converter, a center muffler and two rear mufflers. The exhaust system is separated downstream of the firewall catalytic converter and upstream of the center muffler. The exhaust pipe downstream of the firewall catalytic converter consists of a single pipeline. The exhaust gas flows out of the two rear mufflers through one tailpipe with exhaust tip on each side.

On the M 276, the exhaust system starts with a firewall catalytic converter for the right-hand and lefthand cylinder bank on each side. Downstream of the two firewall catalytic converters, the exhaust flows into the NOx storage catalytic converters (only with engine in stratified operation). Then it flows into the dual-pipe center muffler and then into the left and right rear mufflers, before it exits the exhaust system through a tailpipe with exhaust tip on both the left and right sides. The separating points of the exhaust system are located downstream of the catalytic converter and downstream of the left and right NOx storage catalytic converters.

The exhaust system of the OM 651 consists of an oxidation catalytic converter, a diesel particulate filter (DPF) and two rear mufflers. The oxidation catalytic converter is responsible for reducing hydrocarbons (HC) and carbon monoxide (CO) and, on vehicles with diesel particulate filter (code 474), supplies the required thermal energy for the DPF regeneration phase through afterburning. The diesel particulate filter comprises a ceramic honeycomb filter element made of silicon carbide and coated with rare metal. The passages of the diesel particulate filter are open alternately at the front and rear and separated from one another by the porous filter walls of the honeycomb filter element. The exhaust gas which is precleaned in the oxidation catalytic converter flows into the channels of the diesel particulate filter which open out towards the front and reaches the channels which open out to the rear through the porous filter walls of the honeycomb filter body. Then the cleaned and filtered exhaust gas flows into the left and right rear mufflers, before it exits the exhaust system through a tailpipe with exhaust tip on the left and right sides. The soot particles are held back in the honeycomb filter of the diesel particulate filter. The separating points of the exhaust system are located downstream of the oxidation catalytic converter/diesel particulate filter and just upstream of the branching point.

7G-Tronic Plus transmission
All models are equipped with the familiar 7G-Tronic Plus transmission. The 7G-Tronic Plus has been optimized with modifications to the torque converter and main transmission. This is why the transmission is called 7G-Tronic Plus. It features a new generation of torque converter which offers improved dynamic response characteristics combined with reduced fuel consumption. The consumption-reducing measures include a reduction in drag through a new bearing on the oil pump, improved Torlon rings on the input and output shafts as well as a new automatic transmission fluid (FEATF). The color of the new fluid has been changed from red to blue because it may not be used in older transmissions. The notes in service information SI00.40-P-0014A in WIS on usage of the new transmission fluid must be observed. The oil change intervals have been extended because the transmission fluid is subjected to less energy due to the minimization of drag. For more information, see the corresponding documents in WIS.
Automatic transmission oil supply
General The oil supply to the electrohydraulically controlled automatic transmission is provided by the oil pump (primary pump) with the combustion engine running. The oil pump is driven via the drive flange of the torque converter. It is installed in the transmission bell housing behind the torque converter. Oil supply with combustion engine OFF (stop/start function) When the combustion engine is shut off in ECO start/ stop mode, the oil supply by the primary pump is interrupted. The electric transmission oil pump (auxiliary pump) takes over the oil supply for the control elements and actuators of the automatic transmission. During the subsequent start, initiated e.g. by releasing the service brake, the oil pressure built up by the auxiliary pump ensures that the vehicle is ready to start off spontaneously.

Steering gear
The basic vehicle is equipped with a standard steering gear with constant gear ratio. The standard steering differs from that of the predecessor model series through a new valve characteristic and more direct gear ratio. This reduces the steering requirement when parking to 2.6 steering wheel turns. The steering gear housing features a two-piece design. Both the steering gear housing and valve housing are made of aluminum and have been further optimized with respect to installation space requirements and weight. This allowed a weight saving of 0.5 kg to be achieved. The toothed rack is made of hot forged highstrength steel. In order to further improve the articulation characteristics, the steering gear is rigidly connected to the integral support.
Direct steering
A "direct steering" special equipment option, which also features a new valve characteristic, is available in combination with the agility package. Along with an increase in the hand force required as the vehicle speed increases, direct steering provides the customer with a noticeably more direct steering ratio throughout the steering angle. Compared to standard steering, the vehicle handling and agility are significantly improved and the steering requirement during parking is reduced to 2.2 steering wheel turns.
Economy (ECO) power steering pump
On the SLK, an ECO power steering pump is installed as standard. This has reduced energy requirements during straightahead travel. This is achieved through an additional electrically actuated proportional solenoid valve, which controls a bypass opening at the pressure connection and directs oil to the steering gear as required. This oil quantity and therefore the flow pressure in the steering system are minimal when driving straightahead. This reduces power consumption.

The SLK is equipped with a steering column with manual fore/aft and height adjustment as standard. An electrically adjustable version is available as special equipment. The adjustment travel distances for the manual and electric steering column versions are +/- 25 mm vertically and 25 mm forward and 35 mm back horizontally, measured from the basic position of the steering wheel. i Note If the driver collides with the steering wheel, the steering column can move forwards up to 100 mm in order to reduce the load applied to the vehicle occupant. For this purpose the entire substructure of the steering column tube is suspended on a slide that runs in a mounting console rigidly mounted in the body. In order to largely compensate for the steering gear being pushed back in the event of a heavy frontal impact, the steering shaft can slide together at the bottom and the integrated collapsible tubing of the steering coupling can deform.

General
The materials selected for the axles clearly demonstrate the target-oriented lightweight design practiced on Mercedes-Benz vehicles. The selection of materials and manufacturing processes represents the optimal compromise of geometric requirements, resistance to dynamic driving stresses and crash requirements.
Rear axle
The principle of independent multilink rear suspension has been adopted due to its unsurpassed wheel control qualities. As part of the introduction of an electric parking brake, it was necessary to modify the wheel carrier. A forged aluminum wheel carrier is used in this case to reduce the unsprung masses. All models are equipped with a torsion stabilizer bar which is directly attached to the body.
Front axle
The wheel control components of the front axle including the steering gear are mounted together with the engine and transmission on an integral support. The exceptionally stiff, weight-optimized integral support is made of high-strength steel and is bolted rigidly to the longitudinal members.

Suspension
Suspension systems
Three suspension variants are available for the SLK. In addition to the standard suspension, a sports suspension and a suspension with adjustable damping are also available as special equipment. The standard suspension is a conventional steel suspension with MacPherson front axle struts, torsion bars and double-tube shock absorbers on the front axle with single-tube shock absorbers and rear axle springs on the rear axle. The front axle suspension strut is attached to the body with a triple-path head bearing. The spring forces (static carrying forces) are transmitted directly to the body via the head bearing. The shock absorber forces are transmitted from the shock absorber via the piston rod to the cardan rubber bushing in the head bearing and only then onto the body. Since the rubber bushing does not have to transmit the high static carrying forces, it can be softer and thus optimized for comfort. Buffering forces are transmitted to the body over a separate path via the head bearing.
Suspension with adjustable damping
Along with direct steering and the Torque Vectoring Brake, adjustable damping is a component of the "Agility package" special equipment option. Torsion bars with a larger cross-section are installed with this special equipment. On vehicles with adjustable damping, the driver can switch from a comfortable to a sporty transmission mode by actuating a switch. The damping characteristics are then steplessly adjusted within the selected transmission mode. In Sport mode, the hydraulic forces of the shock absorbers are increased to provide sporty suspension tuning and better driving stability at high speeds.
Sports suspension
Compared to the standard suspension, the sports suspension has shock absorbers with harder tuning, shorter suspension springs and torsion stabilizer bars with a larger cross-section. The vehicle level is lowered by 10 mm and roll support has been strengthened, resulting in lower roll angles during dynamic driving. The sports suspension can optionally be combined with all of the wheel sizes approved for the respective engine.

Electric parking brake
An electric parking brake is installed in the new SLK as standard and acts on the wheels of the rear axle. It makes use of a brake caliper with electric parking brake function. The electric parking brake is operated via the electric parking brake switch, which is located on the left of the instrument panel underneath the light switch. Pressing the switch engages the electric parking brake and pulling the switch releases the electric parking brake. If the control of the electric parking brake is pressed with the vehicle at a standstill or at a speed of below 4 km/h, the combined floating brake caliper closes completely and permanently irrespective of the duration of actuation. Emergency braking function sequence If the switch of the electric parking brake is pressed and held while driving at a vehicle speed of v > 3 km/h, the electric parking brake control unit transmits a braking request to the chassis CAN. The request is received by the following control units: • • • • Electronic Stability Program control unit Instrument cluster Front SAM control unit with fuse and relay module Rear SAM control unit with fuse and relay module via interior CAN from the front SAM control unit with fuse and relay module The vehicle is now braked via the service brake. The rear SAM control unit with fuse and relay module actuates the brake lights. The instrument cluster issues the message "Release parking brake" on the multifunction display and a warning tone is sounded. Automatic release function The automatic release function is only available in combination with an automatic transmission and automatically releases the parking brake when the driver wants to leave a parking space and drive off. This is the case when: • • • • • The engine is running and The transmission is in position D or R and The engine hood is closed and The driver seat belt is fastened and The accelerator pedal is actuated with enough force to start off in the direction of travel.
If the driver seat belt is not fastened, he/she must shift from P to D or R with the driver door closed. When the transmission is in position R, the trunk lid must also be closed. The automatic release function is suppressed as long as the control is pressed. The driver can thus drive off safely in the desired direction without the vehicle rolling backwards.

Network architecture
The network architecture used in the SLK and in other Mercedes-Benz model series represents the current state-of-the-art. The vehicle electronics are networked using the following data bus systems: • Controller Area Network (data bus/CAN bus) (CAN) • Media Oriented System Transport (MOST) Diagnostic CAN The diagnostic tester can be connected to the diagnostic CAN via the diagnostic connector (X11/4). The diagnostic CAN operates at a transfer rate of 500 kBit/s. Front end CAN The front end CAN is responsible for data transfer for the lighting systems. The front end CAN operates at a transfer rate of 500 kBit/s. Chassis CAN The chassis CAN is responsible for data transfer by the chassis and suspension systems. The chassis CAN operates at a transfer rate of 500 kBit/s. Vehicle dynamics CAN The vehicle dynamics CAN is responsible for data transfer of the vehicle dynamics data (e.g. turn rate, longitudinal acceleration). The vehicle dynamics CAN operates at a transfer rate of 500 kBit/s. Drivetrain sensor CAN The drivetrain sensor CAN is responsible for data transfer of exhaust data. The drivetrain sensor CAN operates at a transfer rate of 500 kBit/s. Sensor CAN The sensor CAN is for data transfer between connected control units. The sensor CAN operates at a transfer rate of 500 kBit/s.
CAN
The CAN is an electrical bus system for the transmission of data on two lines. The CAN consists of twisted two-core data lines that connects all CAN subscribers (control units) via a parallel connection. The two lines of the data line must not be swapped (low level/high level). Each connected control unit can send or receive data (bidirectional bus). The following CAN systems are involved in the overall network: Telematics CAN The telematics CAN is responsible for data transfer by the telecommunications systems. The telematics CAN operates at a transfer rate of 125 kBit/s. Interior CAN The interior CAN is responsible for data transfer in the vehicle interior. It interconnects the different systems that can be operated by the driver or the front passenger (e.g. power windows, climate control) etc. The interior CAN operates at a transfer rate of 125 kBit/s. Drivetrain CAN The drivetrain CAN is responsible for data transfer by the drive systems. The drivetrain CAN operates at a transfer rate of 500 kBit/s.
i Note The diagnostic CAN of the SLK is the sole diagnosis communications interface between the external diagnosis test system and the vehicle. The vehicle thus meets the legal requirements for exhaust gas diagnosis.

Restraint systems
Along with the rigidity of the passenger cell, the quality of the restraint systems determines the risk of injury to vehicle occupants in the event of an accident. The best possible protective effect is always achieved by the interaction of seat belts and airbags. Crash sensor system The crash sensor system and its associated software for the detection of the type of accident and severity of accident have been further refined compared to the predecessor model series. New on the SLK are: • The electronic Supplemental Restraint System (SRS) control unit • The pressure sensors in the doors • The acceleration sensors for detecting a pedestrian impact
Protective measures for pedestrians and cyclists
As a supplement to the active measures (e.g. Brake Assist System as standard), measures have been implemented on the body in order to further optimize pedestrian and cyclist protection on the new SLK. An active engine hood is also used on the SLK. A wide range of sensors and actuators in the bumper are read in and actuated by the SRS control unit (N2/10). If the system registers a collision with a pedestrian, pyrotechnical actuators in the area of the engine hood hinges are actuated. This raises the engine hood by 85 mm. The resulting increase in space between the engine hood and the components of the engine compartment causes a relative reduction in the acceleration forces applied to the head of the pedestrian during the impact. The deformation properties of the hood were developed specifically to meet these requirements. The use of aluminum and homogeneous reinforcement on the inside of the engine hood further reduce the loads during an impact. The soft nose allows the impact area to be spread out over a large area. In combination with the reduced foam hardness in the front bumper, this reduces the stress applied if the vehicle collides with the legs of a pedestrian.

General
Modern assistance systems effectively contribute towards accident avoidance. This was the result of analyses carried out by based on representative data from accident research and the evaluation of real-life accidents.
DISTRONIC PLUS including BAS PLUS and PRE-SAFE® brake
The DISTRONIC PLUS driver assistance system automatically regulates the vehicle speed and distance to the vehicle in front as specified by the driver in the speed range of v = 0 to 200 km/h and v = 200 to 0 km/h. The PRE-SAFE® brake continuously determines the risk of a rear-end collision and initiates appropriate collision warning measures in critical situations. If the driver does not respond, it also performs autonomous partial or emergency braking in order to reduce the severity of a collision. The BAS PLUS function (Brake Assist System PLUS) assists the driver through situation-dependent, targeted braking assistance during emergency braking.
i Note For more information on the driver assistance systems listed here, see Introduction into Service Manual "Introduction of the New CLSClass – Introduction into Service Manual for Model Series 218" Order no.: 6516 1381 02
i Note All the driving assistance systems are merely aids for the driver in controlling the vehicle in certain difficult situations. They can never replace a properly relaxed and attentive driver. The driver bears sole responsibility at all times for the safety of his vehicle and its behavior.

Driving assistance systems
Speed Limit Assist and attention assistance system
Speed Limit Assist
The Speed Limit Assist system forms part of the COMAND Online special equipment and uses image detection (integrated camera in center of windshield) to determine the maximum speeds as per the road signage in order to display them symbolically on the instrument cluster. It thus helps the driver to remember the speed limits, including on stretches of road with varying signage and construction site signs.
Attention assistance system
The attention assistance system which is available as special equipment on the SLK can detect the typical signs of fatigue or deteriorating attentiveness of the driver on long, monotonous journeys in a speed range of approx. 80 to approx. 180 km/h. The driver is prompted to take a break through the output of a visual and acoustic warning message. The attention assistance system is switched on via the "Assist." menu in the "Attention Asst." menu level on the instrument cluster. A coffee cup symbol is displayed on the multifunction display.
i Note The behavior of the driver is also analyzed when the attention assistance system is switched off. If the system is switched on while driving, then the entire trip from the beginning is thus taken into account.

Parking assistance
The parking system uses the familiar PARKTRONIC distance warning system in order to record the distance between the vehicle and an obstacle. While driving at speeds of v < 36 km/h, parallel parking spaces on both sides of the vehicle in the direction of travel are measured and stored by the system. The driver is supported during the parking maneuver by appropriate steering and driving prompts. The distance between the vehicle and the obstacle is indicated to the driver visually and acoustically.
Parking space detection
The parking space detection function is implemented via the outer front distance sensors. These monitor the area left and right of the vehicle and therefore have a larger range than the rest of the distance sensors. If a parking space is detected and reverse gear is engaged, "Activate Park Assist?" appears on the display of the instrument cluster. Alongside the warning message "Pay attention to surroundings", the option to activate the parking assistant appears in the lower section of the multifunction display.

Energy savings through new climate control technologies
The R 172 features a humidity/temperature sensor which is integrated in the mirror base of the inside rearview mirror. The sensor measures the windshield temperature and interior humidity in order to detect fogging of the windshield. Using this information, the compressor output can be steplessly reduced when the air conditioning is operating "in dry weather" and "without cooling requirement". The compressor is thus operated according to need, which saves drive energy. The refrigerant circuit features an internal heat exchanger to improve the efficiency of the refrigeration system. The heat exchanger is used to increase the energy content of the refrigerant in the operating ranges and to reduce the mass airflow and thus the operating energy input of the refrigerant compressor, while supplying the same cooling power. This contributes to a reduction in fuel consumption.

The well-known and tried-and-tested Drive Authorization System (DAS) 3 is also used on the new SLK. DAS 3 allows the ignition to be switched on and the engine to be started. DAS 3 is a system network consisting of control units, each of which calculate and compare the drive authorization code independently. If the respective query is valid, the corresponding components are enabled independently.
KEYLESS-GO
The KEYLESS-GO system is available to customers as special equipment. KEYLESS-GO is a convenient operating system whereby the driver carries a KEYLESS-GO key which releases the engine immobilizer and electric steering lock. The key can also be used to control comfort functions such as comfort closing and global or selective locking/unlocking. The electric key for the KEYLESS-GO system can however also be used as on a conventional system.
i Note When the Vario roof is opened or closed, the side windows are included in the process and are forcibly controlled. When the Vario roof is opened, the side windows are first lowered. When it is closed, the Vario roof is closed and then side windows are raised. If the side windows are already in the closed position when the Vario roof is closed, they are first lowered to the short stroke position.

Becker MapPilot
In NTG4.5, Becker MapPilot provides an introduction to the world of navigation. This is a portable map navigation module which can be plugged into a cradle in the glove box by the driver and is easily removable. This connects the Becker MapPilot to the Audio 20 CD. The Becker MapPilot is operated via the central control on the center console. The navigation image is displayed on the central display of the Audio 20 CD (5.8", 400 x 240 pixels). Acoustic output of driving recommendations is integrated into the audio management system of the Audio 20 CD and the recommendations can be output via the vehicle speakers, including lowering the volume of the current audio source (radio, CD, MP3) if required. To ensure reliable position finding of the vehicle even in difficult conditions, the Becker MapPilot uses the GPS antenna of the vehicle. Furthermore, arrows are displayed on the display of the instrument cluster (turn-by-turn) to improve route guidance while driving. Destinations can be entered by voice via the Becker One-Shot voice control system. With this system, the address (town, street, house number) can be spoken in one sentence. Voice input can be started, for example, directly by the driver via a button on the multifunction steering wheel. The MapPilot can be connected to an Internet-capable PC via USB for MapPilot updates and added features. Design The Becker MapPilot consists of the following components • Cradle in glove box • Vehicle GPS antenna • Becker MapPilot as removable navigation module (incl. rechargeable battery) • Retail packaging of Becker MapPilot with USB cable and quick-start operating instructions The Becker MapPilot preinstallation only includes the cradle with wiring and GPS antenna.

Telephone
In terms of telephony, there are two principal versions: basic telephony whereby a mobile phone is connected via Bluetooth® and comfort telephony as special equipment which features a cradle for the mobile phone or SAP module (SIM Access Profile). The SAP module is used to hold a SIM card (Subscriber Identity Module). The SAP module communicates directly with the audio unit and uses the connection to the multifunction antenna. If no SIM card is inserted in the SAP module, the SAP module can use the SIM card of a Bluetooth-capable mobile phone in the vehicle if the mobile phone supports SIM Access Profile. This optional SAP module can now be operated via the head unit HMI (Human Machine Interface) as of version V4. The module will not yet be available at market launch. On vehicles with basic telephony (if the mobile phone supports the Bluetooth® Phonebook Access Profile (PBAP)) and on vehicles with comfort telephony, the contact data of the mobile phone can be transferred to the head unit via Bluetooth®. The downloading of SMS messages is also possible if the mobile phone (on vehicles with basic telephony) supports MAP (Message Access Profile). With both versions, the telephone can be operated via the button groups on the multifunction steering wheel, the head unit buttons, the Audio/COMAND control panel or the LINGUATRONIC voice control system. Voice output takes place via the front speakers.

Bodyshell of SLK 172
The bodyshell structure of the new SLK is an optimized lightweight steel design with even greater torsional stiffness than the predecessor model series, which already possessed a very stiff bodyshell. The structure was also modified in order to meet pedestrian protection requirements. The roadster's lack of a roof structure rigidly connected to the bodyshell means that the structure has to be different to that of a sedan, including a particularly sturdy floor area, in order to achieve the desired stiffness and strength of the passenger cell. The floor area has been optimized based on model series 171 in the area of the seat crossmembers and B-pillar. New developments include a weight-optimized aluminum crossmember under the instrument panel (steel on the R 171) and a rear panel module made of fiber-reinforced plastic. The tried-and-tested A-pillars are unchanged. They have oval tubing welded into them and are made of hot worked, high-strength steel with sturdy gusset plates connecting to the side longitudinal members. The doors have been redeveloped from scratch. They feature an additional outer beltline reinforcement and a new door bottom reinforcement. For side impact protection, the R 172 is equipped with sheet metal section made of increased-strength steel, instead of tubing as on the R 171.
Engine hood and front fenders
In contrast to the predecessor model series, the engine hood and front fenders are made of aluminum for the first time. This has allowed the bodyshell weight to be reduced by approx. 13 kg at the front axle. Furthermore, the components are geometrically designed to provide maximum pedestrian protection. The hinges have a four-link design but an additional link allows the engine hood to be actively raised by means of a pyrotechnical trigger if necessary for pedestrian protection. The engine hood can be steplessly positioned/locked in place from 45° to 80° for service purposes using Interstop pneumatic springs.
Rocker panels
The side longitudinal members are covered over their entire area with plastic rocker panels in the vehicle color, which connect to the fenders and doors at the bottom. The rocker panels protect the side longitudinal members, fenders, doors and side wall from stone chips and also give shape to the side of the vehicle.

Trunk lid
The trunk lid is a steel construction consisting of an internal part, reinforcements in the hinge and lock areas as well as multi-piece paneling which is joined together by laser soldering. The trunk lid can be swiveled in two directions – towards the direction of travel and opposite to the direction of travel. As on the predecessor model series it is made of steel, but this time features a standardized license plate recess. On vehicles equipped with certain special equipment options such as satellite radio for the USA or comfort telephony, it holds an antenna with an aerodynamically favorable design.
Radiator grille
The radiator grille with its large central star and wingshaped lateral fin is integrated into the "soft nose". Its appearance is reminiscent of previous sports car generations from Mercedes-Benz. Underneath the headlamps and the radiator grille is an opening covered by a black diamond-pattern grille for the purpose of engine cooling. Next to the grille are covers with the same diamond-pattern structure, into which the front foglamps and daytime running lamps are integrated.
Doors Bumpers
The bumpers are able to prevent or limit damage e.g. caused by contact with other objects during maneuvering. In order to facilitate parking, the bumpers house painted sensors in combination with the PARKTRONIC special equipment option. The front bumper holds six sensors and the rear bumper holds four sensors. The plastic bumper covers are painted in the vehicle color and connect flush with the outer body panels all the way around the vehicle. The front cover features license plate moldings which vary depending on the national version. The rear bumper has integrated cutouts for the exhaust tips of the exhaust system. The stiff and deformation-resistant sheet steel structure of the frameless door shells consists of an outer panel with an additional beltline reinforcement on the outside and an inner part with integrated mirror triangle, inserted beltline, inner beltline reinforcement, hinge and lock reinforcements as well as a highstrength steel section. The latter is able not only to reduce the deformation depth in the event of a side collision but also to transfer longitudinal forces in the event of a frontal impact. Both door shells are connected to each other with folds and adhesive. The door is attached to the A-pillar with forged steel hinges with integrated door holder.
