2003 MERCEDES-BENZ G55AMG park assist

234 OperationVehicle careVehicle washing
Do not use hot water or wash your vehicle
in direct sunlight. Use only a mild car wash
detergent, such as Mercedes-Benz ap-
proved Car Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water. Direct only a very weak
spray towards the ventilation intake. Use
plenty of water and rinse the sponge and
chamois frequently.
Rinse with clear water and thoroughly dry
with a chamois. Do not allow cleaning
agents to dry on the finish.
Due to the width of the vehicle, fold in out-
side mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Ornamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, turn signal
lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.Cleaning the Rear Park Assist sensors*
1Sensor

Mercedes-Benz approved Car Shampoo,

To prevent scratches, never apply strong

240 Practical hintsWhat to do if …Problem
Possible cause
Suggested solution
-
The yellow ABS malfunction indi-
cator lamp comes on while driv-
ing.
You engaged the differential locks. The ABS,
ESP, BAS, EBB and 4-ETS are switched off.

The driving systems will switch on
again after the differential locks have
been disengaged.
The ABS has detected a malfunction and has
switched off. The ESP, BAS, EBB and 4-ETS
are also switched off (see messages in dis-
play).
If the ABS control unit is malfunctioning, oth-
er systems such as the navigation system or
Rear Park Assist* may also malfunction.
The brake system is still functioning normally
but without the ABS available.

Continue driving with added caution.
Wheels will lock during hard braking
reducing steering capability.

Have the system checked at an autho-
rized Mercedes-Benz Light Truck Cen-
ter as soon as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The ABS has switched off because charging
voltage has fallen below 10 volts. The battery
may not be charged.

Turn off unnecessary electric con-
sumers.
When the battery voltage is above this
value again, the ABS is operational
again.

Note the messages in the multifunc-
tion display (
page 246).
