Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.


The engine electronics may not be op-
erating properly.


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

Give very little gas.

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

Stop the vehicle as soon as possible
and turn off the engine. Allow engine
and coolant to cool.

Check the coolant level and add cool-
ant if necessary (
page 242).In case of accident
If the vehicle is leaking gasoline:

Do not start the engine under any cir-
cumstances.

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

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.
!If leaves, snow, etc. block the wind-
shield wipers, switch off the wipers.

For safety reasons, withdraw key
from starter switch. Remove block-
age.


Turn the windshield wipers on
again.
If windshield wipers fail to function at
all in switch positionI:


Set the combination switch to the
next highest wiper speed.


Have the windshield wipers
checked at the nearest authorized
Mercedes-Benz Center.

Instrument cluster
Coolant temperature gauge
During severe operating conditions and
stop-and-go city traffic, the coolant tem-
perature may rise close to 248° F (120°C),
i.e. close to the red zone of the coolant
temperature gauge.The engine should not be operated with
the coolant temperature above 248° F
(120°C), i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not cov-
ered by the Mercedes-Benz Limited War-
ranty.

not have a red marking denoting excessive
engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive engine speed.
Warning!

Driving when your engine is badly over-
heated can cause some fluids which
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the engine hood. Stay away
f r o m t h e e n g i n e i f y o u s e e o r h e a r s t e a m
coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down.
iExcessive coolant temperatures trigger
a warning in the multifunction display
(page 278).
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.

167 Controls in detail
Automatic climate control
Residual heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.

if the battery voltage dropsVentilated storage compartment under
armrest
The storage compartment under the arm-
rest (
page 200) can be ventilated when
the automatic air conditioning is switched
on. The switch is located inside the storage
compartment in the front. The air tempera-
ture is about the same as that of the center
air vents.
The air volume is dependent on the setting
of:


Air distribution control


Air volume control


Air vents in the dashboard
The air temperature is about the same as
that of the dashboard air vents. It cannot
be regulated separately.
iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting1 regardless of the air distribu-
tion control setting.
