Mercedes-Benz SLK 230 Kompressor Operator's Manual page 170

Once the brake pedal is released, the BAS is deactivated.
The malfunction indicator lamp for the ESP is combined
with the BAS malfunction indicator lamp.
The BAS/ESP malfunction indicator lamp in the
instrument cluster comes on with the key in steering
lock position 2 and should go out with the engine
running.
If the BAS/ESP malfunction indicator lamp comes on
permanently while the engine is running, a malfunction
has been detected in either system. As a result, it is
possible that now only partial engine output will be
available, and pressing the accelerator pedal will
require more effort. If the BAS malfunctions, the brake
system functions in the usual manner, but without BAS.

If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the BAS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
BAS is operational.
With the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lamps come on
with the engine running.
If the malfunction indicator lamp stays illuminated,
have the BAS and ESP checked at your authorized
Mercedes-Benz Center as soon as possible.
