# The battery is no longer charging.
Possible causes:
ț alternator malfunctioning
ț broken poly-V-belt
Do not forget that the brake system re-
quires electrical energy and may be oper-
ating with restricted capability.
Considerably greater brake pedal force is
required and the stopping distance is in-
creased.
̈ 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 in-
operative 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 au-
thorized Mercedes-Benz Center. Ad-
just driving to be consistent with
reduced braking responsiveness.
There is a malfunction in the electronic
system.
̈ Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
