Ì The cooling fan for the coolant is malfunc-
tioning. X Observe the coolant temperature gauge in the
instrument cluster.
If the coolant temperature is under 248‡
(120†), you may continue driving to an author-
ized Mercedes-Benz Center.
X Avoid placing heavy loads on the engine (e.g.
by driving uphill) as well as stop-and-go traffic.
X Have the fan replaced as soon as possible.
# The battery is no longer charging.
Possible causes:
R alternator malfunctioning
R broken poly-V-belt
R a malfunction in the electronic system
Do not forget that the brake system
requires electrical energy and may be
operating with restricted capability. Con-
siderably greater brake pedal force is
required and the stopping distance is
increased.
X Stop immediately in a safe location or as soon
as it is safe to do so and check the poly-V-belt.
X If it is broken: Do not continue to drive. Oth-
erwise the engine will overheat due to an inop-
erative water pump which may result in
damage to the engine. Contact an authorized
Mercedes-Benz Center.
X If it is intact: Drive to the nearest authorized
Mercedes-Benz Center immediately. Adjust
driving to be consistent with reduced braking
responsiveness.
