General
Guidelines for Breakdown Services (Subject to technical modifications)
i
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 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.

Reservoir pressure gauge for brake circuit 1 or 2
왘Turn vehicle key in steering lock to drive position.
The brake circuit with the lowest reservoir pressure
is displayed automatically by the appropriate
indicator lamp 1or 2. The gauge 3shows the
pressure in this brake circuit.
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).
1Brake circuit 1 indicator lamp
2Brake circuit 2 indicator lamp
3Reservoir pressure gauge for brake circuit
1or 2
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.

When the content of the fuel tank has dropped to about 14%, the display shows W. At the same time the
segments of the status indicator light up yellow.
AdBlue®level gauge
The AdBlue®level gauge 1provides only a rough
indication of the AdBlue®supply. The AdBlue®level
is indicated by 4 blue segments in the Instrument.
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.

Standard onboard computer
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.
Buttons and display
The control pad 2and the buttons 3and 4on the instrument panel are used to operate the Standard
onboard computer e.g. to call up displays or to change settings.
Display check
왘Turn vehicle key in steering lock to drive position.
During the display check
• the warning buzzer sounds for about 1 second
• the segments of the status indicator light up yellow
• all the indicator lamps in the instrument panel light up for about 2 seconds
• the ABS equipment is checked
When the display check is complete, the default display appears.
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.
