Possible cause/
consequence
Possible solution
#
The battery is no longer
charging. Possible causes:
alternator malfunctioning
broken poly-V-belt
Do not forget that the brake
system requires electrical
energy and may be operating
with restricted capability.
Considerably greater brake
pedal force is required and the
pedal travel is longer. The stop-
ping distance is increased. If
necessary, apply full pressure
to the brake pedal.
Stop the vehicle immediately in a safe location and
check the poly-V-belt.
If it is broken:
Do not continue to drive. Otherwise, the engine will
overheat due to an inoperative water pump which
may result in damage to the engine. Contact an
authorized Mercedes-Benz Center.
If it is in order:
Contact an authorized Mercedes-Benz Center imme-
diately. Adjust driving to be consistent with reduced
braking responsiveness.
Read and observe additional messages in the
multifunction display.
The starter battery has been
charged with a battery charger
or jump started.
Contact an authorized Mercedes-Benz Center.
There is a malfunction in the
electronic system.
Have the system checked at an authorized
Mercedes-Benz Center immediately.
