Engine cooling
Hydrostatic fan drive The use of a hydrostatic fan drive allows the radiator to be positioned away from the area in front of the engine. The fan is no longer driven directly by the cranksha of the engine. Instead, the fans for the main and additional cooling module are driven hydrostatically by a power take-off (hydraulic pump) on the engine. Fan control is carried out by means of a valve unit. Advantages: • High cooling output at low engine output/engine speed • Optimal adaptation to the main usage profiles of the Econic • No engine overheating even when driving slowly and at high outside temperatures • Separation of the radiator and the engine makes the low entrance and unobstructed passage possible in the Econic Additional radiator The measures required to comply with the Euro 6 emissions standard necessitate a high engine cooling output. An additional radiator is therefore required, which is located on the le of the chassis in front of the compressed air drier/compressed air reservoir.

Hydraulic pump The hydraulic pump is located to the rear of the engine as a power take-off. It is installed in the standard variant on vehicles without additional steering axle. On vehicles with additional steering axle, the version with through-drive and flange for the additional power steering pump is used. Valve unit The fans for the main and additional cooling module are controlled via the valve unit. Fan motor The fan on the front cooling module and the fan on the additional radiator are each driven by a hydraulic motor.

Exhaust system The use of a new exhaust a ertreatment unit is required to fulfill the Euro 6 emissions standard. This is located on the right-hand side of the vehicle (in the direction of travel) on the new Econic. The exhaust a ertreatment unit consists of a diesel oxidation catalytic converter, diesel particulate filter (DPF), ammonia slip catalytic converter and SCR catalytic converter (Selective Catalytic Reduction). The Exhaust system, upwards tailpipe (K7A) is installed as standard on the new Econic. Variants with a tailpipe extended by 600 mm or inward tailpipe are available as special equipment.
Diesel particulate filter regeneration Active regeneration runs automatically. The regeneration cycles depend on the type of usage. The exact point of time is determined by the exhaust a ertreatment control unit (ACM). If necessary, manual activation of regeneration by the driver is possible as soon as the message that regeneration is required is shown on the multifunction display.

Trailing axle, 7.5 t, steered, li able (A4X) The li able trailing axle with 7.5 t load capacity is steered electrohydraulically. The control system records the steering angle of the front wheels and transfers the steering maneuver to the trailing axle in the opposite sense via the hydraulic cylinder and steering linkage. Depending on the vehicle speed, the axle can therefore adopt the following steering states: • Between 15 and 38 km/h: Steering angles reduce • As of 38 km/h: Axle is automatically straightened and centered

Modular switch panel (MSF) On the new Econic, the modular switch panel (MSF) is located centrally on the instrument panel. The MSF consists of an MSF master and multiple switch combinations combined into groups of four, which are designated MSF slaves. MSF switches have their own bus system which they use to receive and transmit signals. There are three types of MSF switches: • Signal switches • Load switches • Special switches Signal switches: • The MSF master determines the switching condition of all individual switches on a cyclical basis and transmits their status on the CAN bus • The MSF master receives all of the required signals relating to function indication and switch and controls illumination on the CAN bus and transmits these requests to the individual switches Load switches: • Load switches can only be inserted in MSF slave modules but not in the MSF master • Load switches are also connected to the MSF master via the bus system because this is how the dimming value for the switch and controls illumination is specified • Due to the wiring, there are some restrictions on the arrangement of the load switches and it may be necessary to extend the load connection • The following load switches are installed in the vehicle:Climate control load switch (standard) Roller sun blind load switch (standard) Special switches: • Special switches have a protective (e.g. EMERGENCY OFF switch)

Control unit network (MUX)
Control unit network (MUX) The control unit network (MUX) in the new Econic is a network of several control units which replaces the previous base module (signal acquisition and actuation module (SAM)). It is primarily used to perform the basic electrical functions of the vehicle such as: • Terminal control • ACC - Accessory (tml.15R) • CRANK (Kl.50) • GENERATOR CHARGING (tml.D+) • Exterior lights • Interior lights • Differential lock control • Horn • 24 V trailer socket • Windshield wipe/wash function
Depending on the configuration and output, loads of up to 10 A can be switched with it. The integrated overload protection function for each output makes the use of external fuses unnecessary. If an output is overloaded by a short circuit, the control unit recognizes overtemperature in the output transistor and shuts off. Attempts are made to re-actuate the output at defined intervals. If overtemperature occurs repeatedly, the output is shut off until the next ignition cycle a er a defined number of attempts.
b Note
The MUX1, MUX2 and MUX3 control units are three identical hardware components. The control units are coded for their respective task by the connected lines and via so ware. When removing and reinstalling these control units, make sure that they are reinstalled in their original position.

General The new Econic is equipped with halogen headlamps and LED daytime running lamps (L1C) as standard. The headlamps are separate from the bumper and protected from damage by their recessed installation. The turn signal lamps and other lighting equipment can be checked for proper operation by the driver as part of a departure check routine by operating the standard „Lighting check“ switch. The lighting check only works with the vehicle at a standstill and the parking brake engaged. Rotating beacon preinstallation (L9A) The Econic is equipped with a preinstallation for rotating beacons as standard. Rotating beacons can be installed on the attachments of the body manufacturer or on the roof of the cab. The electrical preparation is preinstalled as standard up to the inside of the cab roof. Once the interior lamps are removed, the wire ends are accessible. The headliner does not have to be removed in the process. The rotating beacons can be switched on and off via an MSF switch or via a signal input switched to positive (battery voltage). In addition, the parameterizable special module (PSM) provides the possibility of switching on the rotating beacons via CAN signal „BB2_10_RKL_Rq“.

Assistance systems
Driving assistance systems
The following systems are available in the new Econic: • Electropneumatic brake system (EPB) with anti-lock braking system (ABS) and acceleration skid control (ASR) • Stability control assistant • Cruise control Electropneumatic brake system (EPB) The EPB, which is installed as standard, controls all braking and traction functions of the vehicle and the trailer/semitrailer. It provides a high level of road safety because the vehicle remains steerable and stable even during critical braking procedures. Stability control assistant (S1D) The stability control assistant corresponds to the Electronic Stability Program ESP® and has been installed as standard in all new vehicles in ECE countries since 11/2001 in accordance with legal requirements. The risk of the vehicle skidding, jackknifing or rolling over is reduced by means of automatic control interventions in critical driving situations e.g. evasive maneuvers or high-speed cornering.
Cruise control (S5Z) On the Econic, the familiar cruise control system is operated via the corresponding button in the right button group of the multifunction steering wheel.

The maintenance strategy has been taken over from models 963, 964 and 967. The maintenance is subdivided into • W = Maintenance (depending on indication on display) • M = Engine maintenance (depending on indication on display) • J = Time-based maintenance (depending on indication on display) • and various additional maintenance services
b Note
The driver receives an indication that maintenance is due via the multifunction display on the instrument cluster.
New maintenance point Replacement of the diesel particulate filter (DPF) is now an additional maintenance point. Every DPF has its own identification number (see picture). This identification number must be entered in the maintenance booklet and in VeDoc. Before replacing a DPF, this identification number must be checked against the entry in the maintenance booklet/ VeDoc.If the numbers do not match, this means that the exhaust system has been tampered with and the customer must pay the original price and not the exchange price of the DPF. The identification number of the exchanged DPF must be entered in the maintenance booklet/VeDoc again a er installation.

Maintenance service Refer to the respective valid maintenance sheet and the content of the individual maintenance items for the maintenance scope. Safety-relevant maintenance operations must be carried out according to national legislation, but at least once per year unless legal inspections within one year are planned. The maintenance operations to be carried out must be marked with a cross by the service advisor in the fields provided in the top part of the maintenance sheet. The time-based maintenance operations and the additional operations for the maintenance service are marked on the maintenance sheet in front of the relevant operation item. The completion of the individual maintenance items must be recorded by entering a cross in the boxes in front of the operation titles. A cross should be entered in the boxes a er the operation titles to identify items which were not OK when the vehicle was received. Confirmation for this is provided by the mechanic by entering his/her signature in the header section of the maintenance sheet. Operating fluids Since the quality of oil used also affects the service life of a major assembly, this can be set to 3 stages. For engine oil, the viscosity of the oil used is also relevant. The fuel grade also influences the service life, which is why its sulfur content can be set in the menu.

Roughly 2 weeks before a service is due, the driver is informed about this via a pop-up message when the ignition is switched on. The next warning stage appears with the message „Service immediately“. All of the displayed messages are stored in the memory so that, in the event of complaints, it is possible to determine when each message was displayed. Engine oil Engine 936.9 may only be operated with engine oil in accordance with Sheet 228.51 (Multigrade service engine oils, low SPAsh) of the Mercedes-Benz Specifications for Operating Fluids.
Coolant As part of ongoing technical development, the coolant has been changed with the introduction of the new Econic. The previous antifreeze with corrosion inhibitor G48 (green/blue in color) has been replaced by antifreeze with corrosion inhibitor G40 (red in color). Antifreeze with corrosion inhibitor G40 has the following advantages compared to G48: • Fewer deposits in the engine cooling system • Better heat dissipation • Greater environmental compatibility because it no longer includes any ecologically harmful borax components Mixing the two types of antifreeze with corrosion inhibitor is not permissible. A mixture results in rust-brown discoloration. This discoloration can result in possible complaints from customers.
B Warning
Operation with biodiesel (fatty acid methyl ester) is not permissible.
