# BATTERY/ALTERNATOR
VISIT WORKSHOP! The battery was charged with a battery
charger or jump started. ̈ Have the battery checked at a ser-
vice station.
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 operat-
ing with restricted capability. Considerably
greater brake pedal force is required and
the stopping distance is longer.
̈ Stop immediately 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.
