The battery is no longer charg-
ing. Possible causes:
alternator malfunctioning
broken poly-V-belt
Do not forget that the brake
system requires electrical ener-
gy and may be operating with
restricted capability. Consider-
ably greater brake pedal force
is required and the stopping
distance is increased.
Stop your vehicle safely immediately 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. Notify an
authorized Mercedes-Benz Center.
If it is in order:
Drive immediately to the nearest authorized
Mercedes-Benz Center. Adjust driving to be consis-
tent with reduced braking responsiveness.
Observe the additional messages in the instrument
cluster.
There is a malfunction in the
electronic system.
Have the system checked at an authorized
Mercedes-Benz Center immediately.

The Research Octane Number for gaso-
line as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the MON (Motor Octane Number) and
RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.
