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 256).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.

112 Controls in detailInstrument clusterCoolant temperature displayDuring severe operating conditions and
stop-and-go city traffic, the coolant tem-
perature may rise close to 120°C.
The engine should not be operated with
the coolant temperature above 120°C. Do-
ing so may cause serious engine damage
which is not covered by the
Mercedes-Benz Limited Warranty.

Warning!
G


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
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 it
cools down.
iExcessive coolant temperatures trigger
a warning in the multifunction display.

adjustable booster blower
2Left center air vent
3Right center air vent
To open center air vents and to adjust the
booster blower:
Turn thumbwheel1.
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.
iThe booster blower allows airflow
speed to the rear passenger compart-
ment to be increased at four different
levels.
The temperature at the air vents for
rear passenger compartment2 and3
is the same as at the dashboard center
air vents.
