General
Safety and liability information
The aim of these guidelines is to provide roadside assistance and towing personnel with the instructions and information necessary in order to remove the vehicle from the scene of the breakdown or accident within 30 minutes whenever possible.
These guidelines assume that the reader understands and complies with the pertinent accident prevention regulations, any relevant professional guidelines for vehicle ownership or recovery and towing company association regulations, and the road traffic regulations of the country in question.
The instructions in these guidelines, in particular those pertaining to vehicle recovery, are intended exclusively for experienced recovery specialists and are left to the discretion of the user.
Compensation and/or warranty claims arising from towing or recovery measures will not be accepted by Daimler AG.
Risk of accident |
G |
All vehicles that have been towed or recovered from a breakdown must be examined for technical condition and checked for damage at a qualified workshop which possesses all the expertise and tools required to properly perform the necessary work.
Mercedes-Benz recommends a Mercedes-Benz service center for this work. It is absolutely essential that all safety-relevant work and all work on safety-relevant systems is performed by a qualified specialist workshop.
Pay attention to the notes in the chapter "Recovery", see page 8.
Risk of accident |
G |
Tampering with electronic components and their software can cause them to stop functioning. The electronic systems are networked together by interfaces. In some cases, interfering with these electronic systems can also cause malfunctions in systems that were not directly affected. Such malfunctions can put the operational safety of your vehicle, and thus your own personal safety, at considerable risk.
Other improperly performed work or modifications to the vehicle can also jeopardize operational safety.
Some safety systems operate only when the engine is running. For this reason, do not switch the engine off while driving.

Turn vehicle key in steering lock to drive position.
The brake circuit with the lowest reservoir pressure is displayed automatically by the appropriate indicator lamp 1 or 2. The gauge 3 shows the pressure in this brake circuit.
i
Vehicles with Plus onboard computer:
The reservoir pressure of both brake circuits can be shown in the display.
To do this, call up menu Check Info > Reservoir Pressure (see page 25).
Risk of accident |
G |
Leaks in the compressed air brake system put the operational safety of the vehicle at risk. If the reservoir pressure in the compressed air brake system is too low, it is not possible to brake the vehicle. This could make you cause an accident with possible injury to yourself and others.
Do not set the vehicle in motion until the reservoir pressures have been reached and the STOP lamp has gone out.
If the display shows —, do not start to move the vehicle or, if moving, stop it as quickly as possible taking into account the traffic situation. In addition, the segments of the status indicator light up red and the STOP lamp does not go out.
Have the brake system checked and repaired as quickly as possible at a qualified specialist workshop possessing the required expertise and tools in order to perform the necessary work.
Mercedes-Benz recommends a Mercedes-Benz service center for this work. It is absolutely essential that all safety-relevant work and all work on safety-relevant systems is performed by a qualified specialist workshop.
The necessary reservoir pressure for the service brake is 10 bar (constant pressure system).
The ancillary consumer circuit is filled only after brake circuits 1 and 2 have been filled.
The operational safety of the vehicle requires an adequate reservoir pressure in brake circuits 1 and 2 (10 bar) and in the ancillary consumer circuit (8.5 bar).

The current AdBlue® level in liters can be called up on the display of the Standard onboard computer (see page 18) or the Plus onboard computer (see page 25).
If the AdBlue® reservoir is empty or there is a malfunction in the BlueTec® exhaust aftertreatment system, the indicator lamp ±lights up. A display message also appears. In this case the vehicle must be refueled with AdBlue® or the fault must be rectified immediately.

Design and operation
The Standard onboard computer is activated as soon as you turn the vehicle key in the steering lock to the drive position. The Standard onboard computer allows you to call up information about your vehicle and to make and change various settings.
Risk of accident |
G |
Operating the onboard computer while driving can distract your attention away from what is happening on the road. You could lose control of the vehicle and cause an accident.
For this reason, only operate the onboard computer when the vehicle is stationary with the parking brake applied.
