D
The red coolant warning lamp
comes on when the engine is
running.
There is insufficient coolant in the reservoir.
If this warning lamp comes on frequently,
there is a leak in the cooling system.
If the coolant level is correct, the electric ra-
diator fan may be broken.
Immediately add coolant to prevent
engine from overheating
(page 285).
Have the cooling system checked.
If the coolant temperature is below
257 °F (125 °C), you can continue
driving to the nearest authorized
Mercedes-Benz Center.
Avoid high engine loads (e.g. driving
uphill) and stop-and-go driving.
D
The red coolant warning lamp
comes on while driving and you
hear a warning sound.
The coolant temperature has exceeded
257 °F (125 °C).
Stop as soon as possible and allow
the engine and coolant to cool down.
Warning!
G
Driving when your engine is badly overheat-
ed can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

Replacing wiper blades
Installing wiper blades
Slide wiper blade onto wiper arm until
it locks in place.
Rotate wiper blade into position paral-
lel to wiper arm.
Fold the wiper arm backward to rest on
the windshield. Make sure you hold on
to the wiper when folding the wiper arm
back.
!Never open the hood when the wiper
arm is folded forward.
Hold on to the wiper when folding the
wiper arm back. If released, the force
of the impact from the tensioning
spring could crack the windshield.
Do not allow the wiper arms to contact
the windshield glass without a wiper
blade inserted.
Make certain that the wiper blades are
properly installed. Improperly installed
wiper blades may cause windshield
damage.
For your convenience, we recommend
that you have this work carried out by
an authorized Mercedes-Benz Center.
