Problem Possible cause 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.
왘
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
왘
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.
왘
Read and observe messages in the
display (
컄
page 335).
The charging voltage has fallen below
10 volts and the ABS was switched off.
The battery may not be sufficiently charged.
왘 Switch off electrical consumers that
are currently not needed, e.g. seat
heating.
왘
If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.
