Vehicle care
Seat belts
Only use clear, lukewarm water and
soap.
Upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently
discolored. By lining the seats with a
proper intermediate cover,
contact-discoloration will be prevented.Leather upholstery
Please note that leather upholstery is a
natural product and is therefore subject to
a natural aging process. Leather
upholstery may also react to certain
ambient influences such as high humidity
or high temperature by showing wrinkles
for example.
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather
Care.Exercise particular care when cleaning
perforated leather as its underside should
not become wet.
Wood trims
Dampen cloth using water and use
damp cloth to clean wood trims in your
vehicle.
!The seat belts must not be treated with
chemical cleaning agents. Do not dry the seat
belts at temperatures above 176°F (80°C) or in
direct sunlight.
Warning!G
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Warning!G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent the activation
of the active head restraints. Contact an
authorized Mercedes-Benz Center for
availability.
!Wipe with light pressure to avoid damage to
the upholstery.
!Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as these
may be abrasive.

ment cluster fails to come on during thebulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.
ProblemPossible cause/consequenceSuggested solution
-The yellow ABS indicator lamp
comes on while the engine is
running.The ABS has detected a malfunction and has
switched off. The BAS and the ESP® are also
switched off (see messages in the multifunc-
tion display).
The brake system is still functioning normally
but without the systems specified above.
If the ABS control unit is malfunctioning,
other systems such as the navigation
system* or the automatic transmission may
also be malfunctioning.
Continue driving with added caution.
Wheels will lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 378).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery might not be charged sufficiently.Switch off electrical consumers that
