Practical hints
What to do if ...?
Suggested solution
Switch off electrical consumers that are
currently not needed, e.g. seat heat-
ing*.
If necessary, have the generator and
battery checked.
When the voltage is above this value again,
the ABS is operational again and the ABS in-
dicator lamp should go out.
Drive a short distance with added
caution at a vehicle speed of above
12 mph (20 km/h).
When the ABS indicator lamp goes out,
®
the ABS, ESP , BAS and EBP are avail-
able again.
If the ABS indicator lamp does not go out:
Continue driving with added caution.
Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions increas-
es the risk of an accident.
