Problem
-
The yellow ABS indicator lamp
comes on while driving.
Possible cause
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.
The charging voltage has fallen below
10 volts and the ABS was switched off.
Practical hints
What to do if ...
Suggested solution
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 291).
When the voltage is above this value
again, the ABS is operational again.
If necessary, have the generator and
battery checked.
