#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 capa-
bility. Considerably greater brake 
pedal force is required and the stop-
ping distance is increased.
Stop the vehicle immediately in a safe loca-
tion 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 Mercedes-Benz Center 
immediately. Adjust driving to be consis-
tent with reduced braking responsive-
ness.
