Preface
Dear Reader, This Introduction into Service Manual presents the new GLK-Class in model series 204. The purpose of this manual is to inform you of the technical highlights featured in this new vehicle in advance of its market launch. This brochure is mainly intended to provide information for people employed in service, maintenance and repair as well as for aftersales staff. It is assumed here that the reader is already familiar with the Mercedes-Benz model series currently on the market. In terms of the contents, the emphasis in this Introduction into Service manual is on presenting the new and modified systems. This Introduction into Service Manual is not intended as an aid for repairs or for the diagnosis of technical problems. For such needs, more extensive information is available in the Diagnosis Assistance System (DAS) and in the Workshop Information System (WIS). WIS is updated monthly. Therefore, the information available there reflects the latest technical status of our vehicles. The Introduction into Service Manual presents initial information relating to the GLK-Class in model series 204 and, as such, is not stored in WIS. The contents of this brochure are not updated. No provision is made for supplements. We will publicize modifications and new features in the relevant WIS documents. The information presented in this Introduction into Service Manual may therefore differ from the more up-to-date information found in WIS. All of the information relating to specifications, equipment and options are valid as of the publication deadline in June 2008 and may therefore differ from the current production configuration.

Vehicle concept
The market launch of the new GLK-Class will take place in October 2008. This vehicle has no predecessor. It is the entry-level variant of the model range. With the GLK, Mercedes-Benz is offering a crosscountry vehicle in the compact SUV segment for the first time. Its distinctive exterior design gives the vehicle an eyecatching and muscular appearance. This is combined with an outstanding, high-quality interior throughout the vehicle. The new GLK has a dramatic, expressive image with plenty of style and independence. As a supplement to the standard equipment, several special equipment packages are available for the exterior of the GLK. Other special equipment options allow the customer to individually design their vehicle with an offroad tone and a sporty variant is also available optionally.

Front view
The following characteristics dominate the appearance of the new GLK at the front: • Steep front section • Wide, distinctive radiator grille with large, prominent star • Clearly noticeable air intake grille in a matt black diamond-pattern design • Projection headlamps which continue into the fenders to combine the front section with the sides of the vehicle The powerful radiator grille is a striking design feature of the front of the GLK and clearly indicates that this vehicle belongs to the family of Mercedes-Benz crosscountry vehicles. On vehicles with the offroad styling package special equipment option (SA), two smooth chrome slats at the front are responsible for the vehicle's muscular appearance. Vehicles with the exterior sport package feature three smooth chrome slats which give the front section a more refined appearance. Both versions of the radiator grille are painted in brilliant silver. These elements emphasize the sportiness of the GLK. Along with the location of the projection headlamps, the outer position of the front fog lamps also underlines the width of the vehicle. The offroad capability of the variant with the offroad styling package is illustrated by the rub strips on the outer bumpers and the underride guards at the front and rear. These three black-colored elements also emphasize the width of the vehicle and the muscular appearance of the GLK.

Rear view
All of the lines on the sides of the vehicle are brought together at the rear end. The side elements and the rear spoiler continue through to form a harmonious union with the rear end. The trailing edges of the rear section also round off the GLK clearly and serenely above the rear window. Another important element which links the side and the rear of the vehicle are the rear lamps. The prominent shape and the red-white-red horizontally alternating design of the rear lamps again accentuate the wide appearance of the vehicle. The lower section of the rear bumper differs according to the equipment packages installed. The rub strips of the rear bumper and underride guard have been designed to have a robust appearance, which serves to highlight the width of the vehicle and its offroad capability once more. All versions of the vehicle have a twin-pipe exhaust system and vehicles with the offroad styling package, exterior sport package or chrome package also feature exhaust pipes with rectangular chrome-plated tail pieces made of stainless steel.

Side view
The silhouette of the GLK is characterized by the classic elements of a cross-country vehicle: short overhangs, a straight front section, a steep windshield and a tight roof line. This continues past the trailing edge into a distinctive spoiler at the rear end. The height of the vehicle is significantly greater than that of a standard sedan, which gives the driver a good all-round view. The panels in the side windows are high-gloss black in color and blend into the two large vehicle windows at the front and back. This makes the side windows appear to be one large surface, which in turn makes the GLK appear longer. Depending on the equipment installed, the large wheel arches can accommodate up to 20-inch wheels. The offroad styling package features steps with aluminum inserts and rubber naps (SA) to stress the offroad nature of the vehicle. On vehicles with the exterior sport package, the vehicle body is rounded off at the bottom with a distinctive rocker panel in the vehicle color. The specially designed light alloy disk wheels which are available as special equipment underline the offroad look of the vehicle or accentuate its sporty appearance respectively.

Interior design
A lot of attention has been paid to ensuring that the interior compartment of the new GLK-Class is roomy and comfortable. Only high quality materials have been used and these materials emphasize the spacious feeling within the vehicle. The interior equipment consists of the standard equipment and the following equipment variants: • Interior sport package (SA) • Leather interior (SA) • Four different trim versions (fabric, aluminum, "pine" wood and "burred walnut" wood) The first-class materials feature chrome inserts and finely painted or anodized surfaces. Along with the central control, the aluminum COMAND controller, the materials have been processed to a very high standard. The equipment features also nicely complement the ergonomically positioned center console.

Instrument panel
The body of the instrument panel has a single-piece design with an integrated glove box module and large trim surfaces. It is vertically arranged into three distinct areas: • The upper section of the instrument panel is always in black to avoid any reflections in the windshield. • The trim design which has been selected for the vehicle characterizes the central area of the instrument panel. The integrated vents have a slattype design. On vehicles with the interior sport package, the control wheels are also illuminated. • The lower section of the instrument panel is either black, grey or beige depending on the equipment package. The knee guard on the driver side and the center tower are components of the instrument panel. A knee airbag can additionally be installed on the driver side (only for ECE).

Instrument cluster
There are two variants of the instrument cluster. Both variants are characterized by the three round analogue displays positioned in a row. The standard variant comes with a multifunction steering wheel with four buttons, two on the left and two on the right. Each pointer instrument is equipped with a display to keep the driver up-to-date with more detailed information. The extended variant includes an enlarged display (4.5-inch) in the central pointer instrument. The other signal lamps and indicator lamps are located on the left and right-hand sides. The instrument cluster is operated using the multifunctional steering wheel, which features six buttons on the left and right respectively. On this instrument cluster, a segment ring is used for the variable speed limiter and cruise control functions.

Front seats
The backrest consists of a steel frame with a Pulmaflex mat, a foam pad and a lined seat covering. The driver seat is equipped with a manual lumbar support as standard. Both front seats are also equipped with partially electric seat adjustment as standard, which can be used to adjust the inclination of the backrest and the height of the seat cushion. These functions are operated using a switch installed directly on the seat. The following comfort settings can be adjusted conventionally: • Head restraint height and inclination • Seat cushion inclination • Seat fore / aft adjustment The fully electric seat adjustment system (SA) makes it possible to adjust the seats and the front head restraints steplessly and independently of each other using separate switches with memory buttons. The 4way lumbar support can also be adjusted electrically on each front seat. Other features of the special equipment include: • Automatic child seat recognition (ACSR) on the front passenger seat • Fire extinguisher on driver seat • Electrically adjustable front seats with memory function • Electric seat heaters for both front seats • Stowage boxes under the front seats

There are two headlamp variants available for the GLK-Class: • H7 cornering lights with H7 high beams • Intelligent Light System (SA) with bi-xenon headlamps without high beam spot lamp On the GLK-Class, the low beams operate using a projection system with halogen or xenon lights instead of a reflector system. The high beam headlamps still use reflector technology as in the past.

Intelligent Light System
The functions of the Intelligent Light System improve the illumination of the road in different driving situations. Accordingly, the xenon headlamps are adjusted to the various situations encountered. This ensures that other road users are not inconvenienced or dazzled.
Extended driving light functions
• Dynamic curve illumination • Cornering illumination function (via the front fog lamps) • Country lights • Motorway lights • Extended fog light function • Dynamic headlamp range control
Front fog lamps
The front fog lamps are enclosed in the bumper cover. They are positioned low and close to the outer edges of the vehicle, which has the effect of both enlarging the illuminated area and improving the appearance.

Rear lamps
The rear lamps overlap the corners of the vehicle rear in three segments arranged one above the other: • The brake light and taillight is installed behind the upper red covering lens. • In the middle, behind the white lens, is the turn signal with the backup lamp positioned underneath. • The taillight and rear fog light is positioned behind the lower red covering lens. The USA version also includes a side marker lamp. • The center high-mounted brake lamp, which uses LEDs, is located inside the rear window at the top. When the taillights are operating, the two red areas (top and bottom) are illuminated all the way into the inside corners. This improves the visibility and thus the safety of the vehicle at night, as well as highlighting the shape of the rear lamps. Rear lamps with LED turn signals and backup lamps are installed in combination with bi-xenon headlamps.

Restraint system, sensor system and PRE-SAFE® Supplemental Restraint System (SRS) and sensor system
The SRS installed in the GLK, which also takes prospective safety-relevant developments into account, consists of the central airbag control unit and the following sensors: • Two upfront sensors on the flexural member • Two satellite sensors near the bottom of the Bpillars • Pressure sensors in the front and rear doors • Automatic child seat recognition (ACSR) • Triggering of the driver and front passenger airbags • Front and rear side airbags • Pelvis airbags (only USA) • Window airbags • Knee airbag • Emergency tensioning retractor • NECK-PRO head restraints • Seat belt buckle switches (record the belt status on all seats) • Acoustic and visual seat belt reminder warning (for driver and front passenger seat) • Status of front seats (displayed on instrument cluster) • Activation of the pyrofuse • Door release • Window lowering by 50 mm, front • Hazard warning flasher • Engine shutoff und and fuel pump cutoff • Crash-active emergency illumination
PRE-SAFE® system
The PRE-SAFE® system breaches the gap between active and passive safety. It uses the sensor systems of dynamic driving control systems such as BAS and ESP® and, based on the information obtained, can detect dynamic driving situations and critical situations where there is an increased risk of accident. In this type of situation, the time remaining until a (probable) impact is used to activate preventive protection systems. This reduces the risk and further improves occupant protection. Trigger mechanisms of the PRE-SAFE® system: • • • • • Emergency stops Panic follow-up braking Severe oversteer Severe understeer Critical steering movements at high speed (> 140 km / h)
Safety measures
Depending on the driving situation and vehicle equipment, the following measures can be implemented to improve occupant protection: • Motorized seat belt tensioning for the driver and front passenger • Positioning of front passenger seat in the most favorable position for an impact (vehicles with SA memory seat adjustment) • Closing of front and rear side windows and panoramic sliding sunroof (SA) down to a remaining gap of 50 mm when there is a high risk of a rollover If an accident is avoided, the front belts are relaxed again when the vehicle is back inside the critical limits.
Top Tether
The Top Tether system provides the option of making an additional connection between child restraint systems attached using ISOFIX and the rear seat This can reduce the risk of injury even further. The Top Tether anchorings are fixed to the rear of the backrests.

Benefits of maintenance strategy
Motivation/new features
Motivation
Both workshops and the customer will benefit from the extended maintenance scopes from the very first kilometer driven. Effective immediately, we will offer maintenance that is more cost-efficient and competitive without compromising the usual Mercedes-Benz service quality. This can be achieved by making maintenance less complicated and concentrating on the basic service which covers the technically essential items.
New features Maintenance strategy
The previous maintenance scopes of the minor and major basic service (Service A and B) have now been classified as the Basic Service and the PLUS package. The basic package is available for price-conscious customers. Some individual service items, which previously formed part of the maintenance scope, have been omitted from this package. The additional PLUS package allows workshops to offer convenient and helpful service items to their customers. These service items will continue to be performed by Mercedes-Benz Service.
PLUS package
The PLUS package must be offered to the customer by the service advisor during a consultation because it no longer forms part of the maintenance scopes. The aim of the consultation must be to offer the customer a tailor-made package. The "Service-Package-Pricing-System" (SPPS) provides support for the entire process. The actions performed by the dealer and the service items included in the PLUS package are stored in this system.
Digital Service Booklet (DSB)
The introduction of the Digital Service Booklet (DSB) represents a change to the previous service documentation. In future, all service, body and major assembly operations will be documented in a central database using the DSB. The customer receives a service report which he / she stores in the service booklet.

Steering
AGILITY CONTROL steering AGILITY CONTROL suspension with strokedependent damping system
The comfortable spring and damping system of the GLK is equipped with stroke-dependent damping as standard. The AGILITY CONTROL suspension regulates the shock absorber forces depending on the driving situation. When driving at moderate speed on a good road surface, i.e. when the shock absorbers are subject to low levels of excitation, the damper forces are automatically reduced. This noticeably improves the tire comfort without compromising on driving safety. For a more dynamic driving style, the maximum damper forces are applied and the vehicle is stabilized effectively.
The basic steering system of the GLK-Class is the AGILITY CONTROL steering already used in model 204 4MATIC. Speed-sensitive power steering is installed as standard. On this system, the manual torque which has to be applied by the driver and the centering are dependent on the speed. This means that the vehicle can be parked and maneuvered with a minimal amount of manual torque from the driver. On the US market, a steering system especially designed for this market is installed. It is characterized by its lighter design and lower sensitivity to clockwise movement. The GLK-Class is also equipped with a longitudinally and vertically adjustable steering column. Optionally available as special equipment is an electric longitudinal and vertical adjustment version with Easy Entry function, which is included in the memory package (SA).

Front axle
Main features of front suspension: • Two individual control arms (strut rod and cross strut) • Torsion stabilizer bar • Suspension strut • The third link is the tie rod, which forms part of the rack-and-pinion steering. The two individual control arms are positioned towards the bottom of the steering plane. The tie rod forms a third link as a laterally positioned steering gear. It is located just in front of the wheel center. The longitudinal force leverage is very small and the sensitivity to vibrations very low. The stabilizer bar is connected to the suspension strut. For general weight reduction purposes, the strut rod and cross strut are made of aluminum. The positioning and design of the wheel control parts, especially the separation of the lower wishbone control arm into two individual control arms, offers the following advantages: • Improved axle kinematics • The scrub radius has been set closer to zero • Sensitivity to vibrations due to unbalanced tires and brake force fluctuations is minimized • Improved occupant protection due to the deformation capability of the lower steering plane in a frontal impact The position of the rack-and-pinion steering in front of wheel center produces desirable self-steering behavior under lateral forces. The steering gear and engine mount are bolted directly to the body via a carrier.

Rear axle
An independent multilink rear suspension has been installed due its particular wheel control qualities. It sits on the frame-type integral support and the track width is 33 mm larger than that of the model 204 wagon. The axle has been modified in terms of the height and thickness of the individual components on the frametype integral support, the frame-type integral support bearing, the wheel carriers, steering knuckles and struts. The lightweight construction has been continued throughout. Smaller panel thicknesses and aluminum components lower the on-road weight and minimize the resulting forces. These advantages allow the responsiveness and ride comfort of the GLK to better stand out. An additional support for the front frame-type integral support bearing on the body reduces vibrations and keeps driving noise to a minimum. In addition, all models are equipped with a torsion stabilizer bar which is directly attached to the rear axle.

Suspension and damping
The GLK-Class is equipped with a conventional steel suspension. This incorporates a wheel-controlling front axle suspension strut, a torsion bar at the front axle and rear axle and a rear axle spring and shock absorber with a separated design. The front axle suspension strut is attached directly to the body with a triple-path head bearing. The spring forces are transmitted directly to the body. Damper forces against the body are first transmitted to the movable rubber mount by the piston rod and then on to the body itself. The connection of the rear axle shock absorbers operates in the same way although there is no transmission path for the spring forces due to the separated design. Both the front axle and the rear axle head bearing housings are made of aluminum. An exterior sport package with a more tightly tuned sports suspension featuring a 20 mm lower vehicle level and 19-inch light alloy disk wheels is available as a special equipment option.

ADAPTIVE BRAKE system
The ADAPTIVE BRAKE brake control system, which is already used in the model 204 sedan and wagon, is also used in the new GLK-Class. The ADAPTIVE BRAKE system incorporates the ABS and ASR control functions essential for traction and vehicle dynamics as well as a yawing moment control function. The BAS function, the cruise control and the tire pressure loss warning system, as well as the enhancement functions of Hill Start Assist, dry braking and precharging, are included as before. This improves the performance of the vehicle in terms of traction potential and driving safety both on the road and offroad. The ESP® trailer stabilization function is also installed as standard. The sway of the tractortrailer combination is also reduced by brake interventions at individual wheels.
Downhill Speed Regulation (DSR)
The DSR function facilitates downhill driving. The vehicle speed is controlled via electronic intervention in the engine and transmission control systems and via brake system interventions. When DSR is active, the setting can be made temporarily using the cruise control lever. The set speed is 4 km / h and can be adjusted in two stages (1st stage 1 km / h, 2nd stage 2 km / h) up to a maximum of 18 km / h.

Hill Start Assist
The Hill Start Assist function prevents the vehicle from rolling backwards immediately when starting off on an uphill slope. This system maintains the required brake pressure for a short period of time after the brake pedal is released. This allows the driver to comfortably move his / her foot from the brake pedal to the accelerator pedal without the vehicle rolling back straight away. The system detects an uphill slope automatically and activates the Hill Start Assist function.

Network architecture
On recent systems, one of the characteristics of the network topology for electronic control units is the division of the network into two subnetworks (engine CAN Class C and interior CAN Class B) which are linked to each other via the electronic ignition lock (EZS). In addition, a gateway function integrated in the head unit connects the MOST (Media Oriented System Transport) telematics network to the interior bus. The most important differences to the previous network architecture include: • Linking of the CAN subnetworks via several control units with integral gateway functions • Use of numerous subbus systems in the form of single-wire buses (LIN for Local Interconnect Network).
Electrical wiring harnesses and fuses
The wiring harnesses for the interior compartment, cockpit and engine compartment are designed customer-specifically. The wiring harness variants result from the basic standard equipment, the engine type, special equipment and national versions. The wiring harnesses in the interior compartment are routed through the frame floor system in a H-shape and are protected by cable ducts in critical areas. The vehicle fuses are accessible at the following points: • Front SRB (engine compartment) and rear SRB (trunk) • Cockpit fuse box (outer left) depending on equipment
Diagnostic CAN
On the GLK-Class, the diagnostic CAN is the sole diagnosis communications interface between the external diagnosis test system and the vehicle. It offers the benefits of a high data transfer rate (500 kB) combined with the ability to diagnose control units simultaneously. The vehicle thus meets the legal requirements for exhaust gas diagnosis. All CAN and MOST control units have diagnosis capability. LIN components are diagnosed through their associated master control units. Each control unit has its own internal fault memory.
i Note The prefuse box contains a pyrofuse that isolates the starter and alternator lines from the battery in the event of an accident.

On-board electrical system
The ability of the vehicle to start is the top priority. The aim of the on-board electrical system management is therefore to ensure a positive battery charge balance. The vehicle uses a number of different variables to determine the current load state of the on-board electrical system. This allows suitable measures to be implemented quickly when required. Examples of these include changes to charging voltage specifications, alternator rpm increases and reductions in the power consumption of individual convenience consumers. To allow the vehicle to remain idle for long periods, the load on the battery from the quiescent current must be as low as possible. In addition to the optimization of individual components, two other measures have been introduced: • Decentralized power management • Quiescent (no-load) current switch
Quiescent (no-load) current switch
In order to prevent undesirable control unit activities when the vehicle is not in use, decentralized power management is integrated into all control units as a standardized software module. The quiescent current switch is a bistable relay that is opened by the onboard electrical system management when the vehicle is idle and the run-on time has elapsed. All control units that are not needed when the vehicle is idle are still disconnected from the battery. This minimizes the quiescent current demand.

THERMATIC 2-zone automatic air conditioning
In vehicles with THERMATIC 2-zone automatic air conditioning, the interior temperature is adjustable separately on the left and right sides. Air is blown in at different temperatures via the respective left and right vent openings to set different temperature levels as required. In automatic mode the blower speed is steplessly controlled depending on the difference between the specified and actual temperatures. Two interior temperature sensors and the signal from the outside temperature sensor are used to control the system electronically. At high outside temperatures, the system automatically reduces the proportion of recirculated air to cool the entire passenger compartment more rapidly and to minimize the demand for cooling capacity. A sun sensor records the intensity and direction of the incident solar radiation and adjusts the interior temperature by automatically changing the air flow rate and the temperature of the air blown out through the vents. A high-quality display with white LED indicators on the AC operating unit displays the manual air distribution settings and a total of seven manually selectable blower settings. On the THERMATIC operating unit, the entire climate control system can be deactivated via a separate OFF button in the upper row of buttons. When the MONO button is pressed, all of the settings from the driver side are transferred to the right-hand side. There are seven possible air distribution combinations for the window ventilation, center area and footwell. It is possible to quickly change the air flow rate manually via two blower buttons.

Side doors
The side windows on the doors can be operated electrically at the front and at the rear. The door panel lining features a new design. The controls on the door are well positioned in the field of view of the driver and front passenger and have been arranged to meet ergonomic requirements. All door panels feature a soft beltline, an armrest and a soft center panel. The door shells, including the side window frames, feature an inner sheet steel shell with outer reinforcements. The hinge-bearing sheet steel surface is separated from the inner shell. This makes it possible to use a thicker panel to improve the distribution of forces in the area of the hinge with only a low weight penalty. The driver, front passenger and rear doors are each equipped with a diagonal side impact strut and a dent resistance strut running in the longitudinal direction. In the event of side impacts, these spot-welded and bonded reinforcement profiles reduce the deformation depth while also improving dent resistance and aeroacoustics.

Mild steel High-strength steel Modern high-strength steel Ultra high-strength steel Aluminum
Front end
In order to ensure that the vehicle structure absorbs the largest possible amount of energy in a frontal collision, the crumple zones and force transmission patterns have been consistently designed in accordance with the latest findings on safety technology. The measures in the front-end section include: • A sturdy firewall crossmember between the two Apillars made of super high-strength steel • Vertical support made of super high-strength steel on the driver side for supporting the firewall crossmember against the crossmember under the wind deflector in order to reduce firewall intrusion in the area where the steering column penetrates the firewall. • Longitudinal members in the upper impact plane (second longitudinal member plane) with improved connection to the A-pillars • Central impact plane featuring longitudinal members with improved crash kinematics • Frame-type integral support made of high-strength steel (engine, steering and front axle mounts are bolted firmly to the longitudinal members), which is specifically designed to contribute to deformation in the event of a frontal impact. • Front axle with separated front axle control arms • Additional support structures for protecting the footwell (pedal floor panel crossmember) • Full-length floor longitudinal members for improving the application of force to the floor structure • Strut made of super high-strength steel between the shock absorber tower and wind deflector crossmember on the driver side for distributing forces and reducing rearward movement of the steering and pedals
Passenger cell
The core of the body safety concept is the highstrength passenger cell in the form of a safety cage. Its high strength under the stresses of an accident (frontal, side-on and rear-end collisions as well as rollovers) is due to: • Increased use of high-strength and super highstrength sheet steel and sheet metal of graduated wall thicknesses • Stress-resistant materials and sheet thicknesses for components or structural zones that are subjected to high loads in the event of an accident • More advanced shaping and cross-section designs Particular emphasis was placed on developing the strength of the entire side wall. This included: • Side wall with B-pillar and roof frame made of hot worked steels, a robust beltline reinforcement between C-pillar and D-pillar and a roll-formed rocker panel with lateral and longitudinal reinforcements • Transversely rigid floor assembly, a full-width raised rear seat crossmember and a connecting carrier between tunnel and rocker panel • Installation crossmember under instrument panel between A-pillars • Stiff rear-end door cutout • Transversely rigid seats with tubes and impact elements in the side seat trim parts • A transversely rigid installation strut between the B-pillars

Front end
The front end consists of: • An extruded aluminum section • A single-part aluminum crash box connecting the front longitudinal members • A multi-piece framework of sheet steel for holding the headlamps, the bumper, the washer fluid reservoir and the engine hood catches The entire front end is bolted to the frame forestructure, as are the individual components of the front end to each other. If any parts are damaged, this makes it possible to replace them more cost-effectively and with no welding required.
Side wall
The side wall is a single-piece unit. The outsides and insides are connected at various points during assembly. This is done in such a way as to ensure that the cross sections of the A, B, C and D-pillars, the side longitudinal members and the roof frame have the appropriate strength and rigidity. Additional sheet metal reinforcements are also welded in, which extend across the entire length of the A, B, C and D-pillars.
Rear area
In order to conform to the specific geometry of the GLK, the independent multilink rear suspension, the fuel tank and the spare tire well are located at the rear end in accordance with the body structure. The rear area is fitted with additional longitudinal and lateral reinforcements in order to cope with the heavy stresses placed on the vehicle structure in a rear-end collision. The fasteners for the backrest and the hinges and catches of the folding 1 / 3 and 2 / 3 rear backrest are mounted on an all-round structure. The structure is welded to the inner shell of the side wall and to the floor panel at the bottom. This also improves the torsional stiffness of the bodyshell.
Crossmember under the instrument panel
The load-bearing element is a square aluminum tube bolted onto the two A-pillars. To prevent the steering wheel from shaking when the engine is idling, a strut is used to support the steering column tube against the firewall. All the major assemblies located in the vicinity of the instrument panel, the steering column tube and the instrument panel itself, are attached to the crossmember with brackets and mounting consoles.

Minor damage
In order to ensure repair costs are kept as low as possible, during development particular emphasis was placed on reducing the susceptibility of the GLK to potential sources of damage. The bumpers are able to prevent or limit damage caused by contact with other objects during maneuvering. The foam elements are box-shaped and are enclosed by a flexural member and the outer bumper cover. On vehicles with the offroad styling special equipment option, black rub strips are also integrated into the outsides of the front bumper. A black underride guard is positioned at the front in the center. The rub strips can be replaced at any time with minimal effort.
Safety measures
In order to prevent leg injuries to pedestrians in the event of a collision, a stiff carrier part has been installed in the lower section of the bumper. This carrier part diverts the force of the impact into the engine compartment paneling. Elements made of energy-absorbing polypropylene have also been integrated. These deform when a flexural member is placed under stress and then automatically return to their previous shape.

Corrosion protection
Long-term protection against corrosion is guaranteed by full galvanization of the steel body components. Structural areas that are particularly susceptible to corrosion are protected by additional cavity preservation. To supplement this, the following protective measures are used in addition to regular galvanizing in the manufacture of the sheet steel: • Use of organically coated sheet steel • Cataphoretic immersion primer bath • Seam sealing
Underfloor protection
Because the underfloor area is entirely covered with DLFT (Direct Long Fiber reinforced Thermoplastic), PVC underfloor protection has been omitted. The advantages are: • Lower aerodynamic drag • Replaceable if damaged (easy to repair) • Detachability for vehicle recycling • Increased impact resistance (stone chipping protection)
