55 Getting started
Driving
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 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 303).In case of accident
If the vehicle is leaking fuel:
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.

200 Controls in detailDual-zone automatic climate controlThe climate control is operational whenev-
er the engine is running. You can operate 
the climate control system in either the au-
tomatic or manual mode. The system cools 
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.Nearly all dust particles, pollutants and 
odors are filtered out before outside air en-
ters the passenger compartment through 
the air distribution system.
The air conditioning will not engage (no 
cooling) if the AC
OFF
 mode is activated or 
AC mode is deactivated (
page 206).
Warning!
G
When operating the climate control, the air 
that enters the passenger compartment 
through the air vents in the footwell can be 
very hot or very cold (depending on the set 
temperature). This may cause burns or frost-
bite to unprotected skin in the immediate 
area of the air vents. Always keep sufficient 
distance between unprotected parts of the 
body and the footwell air vents. If necessary 
change the air flow using the air distribution 
controls (
page 198) to direct the air away 
from the footwell air vents.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up, 
impairing visibility and endangering you and 
others.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A 
clogged filter will reduce the air volume 
to the interior.
If the vehicle interior is hot, ventilate 
the interior before driving off.
Keep the air intake grille in front of the 
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust 
slots below the rear window.

206 Controls in detailDual-zone automatic climate controlAir conditioning
The air conditioning is operational while 
the engine is running and cools the interior 
air to the temperature set by the operator.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate 
control system. The air in the vehicle will 
then no longer be cooled or dehumidified.

page 198).
The indicator lamp on the button 
comes on.
The cooling function is switched off.
Climate control panel design B 
Press buttonœ (
page 199).
The indicator lamp on the button goes 
out.
The cooling function is switched off.Activating
Moist air can fog up the windows. You can 
dehumidify the air with the air condition-
ing.

page 198) again.
The indicator lamp on the button goes 
out.
Climate control panel design B
Press buttonœ (
page 199) again.
The indicator lamp on the button 
comes on.
The air conditioning uses the refrigerant 
R134a. This refrigerant is free of CFCs 
which are harmful to the ozone layer.
iCondensation may drip out from under-
neath the vehicle. This is normal and 
not an indication of a malfunction.Warning!
G
If you turn off the cooling function, the 
vehicle will not be cooled when weather 
conditions are warm. The windows can fog 
up more quickly. Window fogging may 
impair visibility and endanger you and 
others.
