and replaced if necessary.Problem
Possible cause/consequence
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 dis-
play).
The brake system is still functioning nor-
mally but without the ABS available.
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 may lock during hard braking,
reducing steering capability.

Read and observe messages in the dis-
play (
page 358).

Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions
increases the risk of an accident.
The charging voltage has fallen below ten
volts. The ABS has switched off.
The battery might not be charged suffi-
ciently.

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

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

airbag
activated
See Operator’s
Manual
Front passenger front air bag is
activated while driving even though
a child, small individual, or object
below the system’s weight
threshold is on the front passenger
seat, or the front passenger seat is
empty. Objects on the seat or
forces acting on the seat may
make the system sense supple-
mental weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Switch off the ignition (
page 33).

Remove child and child restraint from front passenger seat and proper-
ly secure the child in rear seat employing the child restraint if neces-
sary.

Make sure that no objects applying supplemental weight onto the seat
are present. The system may recognize such supplemental weight and
sense that an occupant on the front passenger seat is of a greater
weight than actually present.

Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
