58 Getting startedDrivingSingle wipe
Press the combination switch briefly in
direction of arrow1 (
page 56) to
the resistance point.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid

Push the combination switch in direc-
tion of arrow1 (
page 56) past the
resistance point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system*”
(
page 292).
Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.


The engine electronics may not be
operating properly.


Unburned gasoline may have entered
the catalytic converter and damaged it.

Give very little gas.

Have the problem repaired by an
authorized Mercedes-Benz Center as
soon as possible.
The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.

Stop the vehicle in a safe location as
soon as possible and turn off the en-
gine. Allow engine and coolant to cool
off.

Check the coolant level and add cool-
ant if necessary (
page 290).
In case of accident
If the vehicle is leaking fuel:

Do not start the engine under any
circumstances.

Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be
determined:

Notify an authorized Mercedes-Benz
Center.
If no damage can be determined on the


major assemblies


fuel system


engine mount:

Start the engine in the usual manner.
i
To prevent smears on the windshield or
noisy/chattering wiper blades, wipe with wind-
shield washer fluid every now and then even
when it is raining.

!
If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks immediately. Notify an
authorized Mercedes-Benz Center immediately.
Do not add brake fluid as this will not solve the
problem. For more information, see “Practical
hints” (page 344).

290 OperationEngine compartmentCoolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze. To check
the coolant level, the vehicle must be
parked on level ground and the engine
must be cool.
The coolant expansion tank is located on
the driver’s side of the engine compart-
ment.
1Marking bar in the expansion tank
2Cap
3Coolant expansion tank

Using a rag, turn cap2 slowly approx-
imately one half turn counterclockwise
to release any excess pressure.

Continue turning the cap2 counter-
clockwise and remove it.
The coolant level is correct if the level:

for cold coolant: reaches marking
bar1 in the expansion tank3


for warm coolant: is approximately
0.6 in (1.5 cm) higher

Add coolant as required.

Replace and tighten cap2.
For more information on coolant, see the
“Technical data” section (
page 453).
Warning!
G
In order to avoid potentially serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.


Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.


Using a rag, slowly open the cap approx-
imately
1/2 turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out
under pressure.


Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.

347 Practical hints
What to do if …
Problem
Possible cause/consequence
Suggested solution
D
The red coolant temperature
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
radiator fan may be broken.

Immediately add coolant to prevent
engine from overheating
(page 290).

Have the cooling system checked.

If the coolant temperature is below
248°F (120°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 temperature
warning lamp comes on while
driving and you hear a warning
sound.
The coolant temperature has exceeded
248°F (120°C).

Stop in a safe location as soon as pos-
sible 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.

456 Technical dataFuels, coolants, lubricants etc.Windshield washer system and head-lamp cleaning system*
