General

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.

Conventions

Risk of accident

$

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 190.

Risk of accident

$

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.

Reservoir pressure gauge for brake circuits 1 and 2

To ensure the operational safety of your vehicle a reservoir pressure of about 10 bar is required in the pressure circuits of the brake system.

The ancillary consumer circuit is filled only after brake circuits 1 and 2 have been filled.

: Reservoir pressure, brake circuit 1 ; Reservoir pressure, brake circuit 2

Risk of accident

$

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 or change gear. You could cause an accident with possible injury to yourself and others.

Do not set the vehicle in motion until the required reservoir pressures have been reached and the STOP lamp has gone out.

If the display shows J, 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 status indicator lights 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.

Note on display messages

Each malfunction in an electronic system (e.g. tachograph) is indicated by a display message, and is stored and assigned to a malfunction class.

Malfunctions within various electronic systems can be displayed sequentially (with each display message lasting about 5 seconds). If there are multiple malfunctions in an electronic system, only the display message with the highest priority is shown.

In the event of failure or malfunction of an electronic system, the display shows either the system abbreviation with a display message or the event code.

Reservoir pressure gauge for brake circuits 1 and 2

To ensure the operational safety of your vehicle a reservoir pressure of about 10 bar is required in the pressure circuits of the brake system, or 11 bar in vehicles with Electronic Air-Processing Unit (EAPU), see page 136.

The ancillary consumer circuit is filled only after brake circuits 1 and 2 have been filled.

M Turn vehicle key in ignition lock to drive position.

The brake circuit with the lowest reservoir pressure is displayed automatically by the appropriate indicator lamp : or ;. The gauge = shows the reservoir pressure in this brake circuit.

Reservoir pressure (example on Actros 2) : Brake circuit 1 indicator lamp

; Brake circuit 2 indicator lamp

= Reservoir pressure gauge for brake circuit 1 or 2

You can check the reservoir pressure of both brake circuits in the Check Info menu under Reservoir pressure.

Risk of accident

$

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 or change gear. You could cause an accident with possible injury to yourself and others.

Do not set the vehicle in motion until the required reservoir pressures have been reached and the STOP lamp has gone out.

If the display shows J, 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 status indicator lights 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.
