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 286).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:

Center.
If no damage can be determined on the


major assemblies

the KEYLESS-GO* start/stop
button and open the driver’s
door (with the driver’s door

127 Controls in detail
Instrument cluster
Coolant temperature indicator
During severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture 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.
Trip odometer
Make sure you are viewing the trip odome-
ter display (
page 129).

If it is not displayed, press buttonè
orÿ on the multifunction steering

ter appears.

Press and hold reset button1 on the

the trip odometer is reset.
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 hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.
iExcessive coolant temperature triggers
a warning in the multifunction display
(page 323) and the red coolant warn-
ing lamp in the instrument cluster
comes on (
page 309).

182 Controls in detailAutomatic climate controlDeactivating
Press button° (
page 173).
The indicator lamp on button°
goes out.
The residual heat is automatically turned
off:


when the ignition is switched on


after about 30 minutes


if the battery voltage dropsRear passenger compartment adjust-
able air vents
1Thumbwheel for center air vents with
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.
