sumers.

The battery is no longer charging.
Possible causes:
ț alternator malfunctioning
ț 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 stopping distance is
increased.
̈ Stop immediately in a safe location or
as soon as it is safe to do so 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 re-
sult in damage to the engine. Notify
an authorized Mercedes-Benz Center.
If it is intact:
̈ Drive immediately to the nearest
authorized Mercedes-Benz Center.
Adjust driving to be consistent with
reduced braking responsiveness.
