Problem
Possible cause/consequence
Suggested solution
-
The yellow Antilock
Brake System (ABS)
indicator lamp comes on
while the engine is run-
ning.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be charged sufficiently.
When the voltage is above this value again,
the ABS is operational again and the ABS in-
dicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and the
battery checked.
When the voltage is above this value again,
the ABS is operational again.
;(USA only)3(Canada only)-
v
The red brake warning
lamp comes on while the
engine is running. In addi-
tion, the yellow ABS mal-
function indicator lamp,
and the yellow ESP
®
warning lamp come on
and an acoustic warning
sounds.
A malfunction in the Electronic Brake Pro-
portioning (EBP) was detected. The ABS,
BAS, ESP
® and PRE-SAFE
® are also
switched off (see messages in multifunction
display).
The brake system continues to function
normally, but without electronic support.

Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.

Read and observe messages in the mul-
tifunction display (
page 622).

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.
