Display messagesPossible causes/consequences and M Solutions#The battery is no longer charging.
Possible causes:
R alternator malfunctioning
R broken poly-V-belt
R a malfunction in the electronic system
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 stopping
distance is increased.XStop immediately in a safe location or as soon as it is safe
to do so and check the poly-V-belt.XIf 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.XIf it is intact: Drive to the nearest authorized Mercedes-
Benz Center immediately. Adjust driving to be consistent
with reduced braking responsiveness.#Battery/
Alternator

and therefore has only limited operation. Considerably
greater brake pedal force is required and the stopping
distance is increased.XStop the vehicle in a safe location or as soon as it is safe
to do so.XAdjust driving to be consistent with reduced braking
responsiveness.XContact an authorized Mercedes-Benz Center.4Engine
