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 303).

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.
l
The red DTR warning lamp
comes on while driving.
You are too close to the vehicle in front of you
to maintain selected speed.

Apply the brakes immediately to in-
crease the following distance.
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.

Before you start to replace a bulb for a
front lamp, do the following first:

Turn the exterior lamp switch to
positionM (
page 141).

Open the hood (
page 299) (except
for side marker lamps).
Warning!
G

Bi-Xenon* headlamp. Because of high
voltage in Xenon* lamps, it is dangerous to
replace the bulb or repair the lamp and its
components. We recommend that you have
such work done by a qualified technician.

417 Practical hints
Replacing wiper blades
Installing wiper blades
Slide the wiper blade onto wiper arm
until it locks in place.

Rotate the wiper blade into position
parallel 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.
