Vehicle care
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 dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Leather upholstery
Wipe leather upholstery with a damp cloth
and dry thoroughly or clean with
Mercedes-Benz approved Leather Care.
Exercise particular care when cleaning per-
forated leather as its underside should not
become wet.Plastic and rubber parts
Do not use oil or wax on these parts.
Wood trims
Dampen cloth using water and use damp
cloth to clean wood trims in your vehicle.
Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as
these may be abrasive.

Suggested solution
-
The yellow ABS indicator lamp
comes on while driving.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP are also
switched off (see messages in display).
The SBC brake system is still functioning nor-
mally but without ABS available.
If the ABS control unit is malfunctioning, oth-
er systems such as Parktronic*, Distronic*,
or the automatic transmission may also be
malfunctioning.

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

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.

Read and observe messages in the
display (
page 335).
The charging voltage has fallen below
10 volts and the ABS was switched off.
The battery may not be sufficiently charged.

Switch off electrical consumers that
are currently not needed, e.g. seat
heating.

If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.

sult in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You
can be seriously burned.
!If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.

The yellow engine malfunction
indicator lamp comes on while
driving.
There is a malfunction in:

The fuel injection system


The ignition system


The emission control system


Systems which effect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode.

Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics sys-
tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located in the front left
area of the footwell next to the park-
ing brake.
The fuel cap is not closed tightly.

Check the fuel cap (
page 267).
If it is not closed properly:

Close the fuel cap.

engine from overheating
(page 276).

Have the cooling system checked.

If the coolant temperature is below
248 °F (120 °C), you can continue
driving to the nearest authorized
Mercedes-Benz Center.

Avoid high engine loads (e.g. driving
uphill) and stop-and-go driving.
