Mercedes-Benz 2003 SLK 230 Kompressor Operator's Manual page 195

Problem
¿ The yellow BAS/ESP malfunction
indicator lamp comes on while
driving.
Possible cause
The ESP is deactivated because of an inter-
rupted power supply. The ABS may still be
operational.
The BAS has detected a malfunction and
switched off. The brake system is still func-
tioning normally but without the BAS avail-
able.
The charging voltage has fallen below
10 volts and the BAS has switched off.
Practical hints
What to do if ...?
Suggested solution
With vehicle stationary and the engine
running, turn the steering wheel com-
pletely to the left and then to the right
to synchronize the ESP.
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 in-
creases the risk of accident.
When the voltage is above this value
again, the BAS is operational again.
If necessary, have the alternator and
battery checked.
