Automatic climate control*
Air conditioner
The air conditioner 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 automatic 
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.
Press button AC
OFF
The indicator lamp on the 
button AC
OFF
 lights up.
Activating
Moist air can fog up the windows. You can 
dehumidify the air with the air conditioner.
Press AC
OFF
 again. 
The indicator lamp on 
the AC
OFF
button goes out.
The air conditioner uses the refrigerant 
R134a. This refrigerant is free of CFCs 
which are harmful to the ozone layer.
Warning!
G
Any accumulation of snow and ice should be 
removed from the rear window before driv-
ing. Visibility could otherwise be impaired, 
endangering you and others.
!
If the rear window defroster switches 
off too soon and the indicator lamp 
starts blinking, this means that too 
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system 
responds automatically by deactivating 
the rear window defroster. 
As soon as the battery has sufficient 
voltage, the rear window defroster au-
tomatically turns itself back on.
i
Condensation may drip out from under-
neath the vehicle. This is normal and 
not an indication of a malfunction.
!
If the air conditioner cannot be turned 
on again, this indicates that the air con-
ditioner is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioner checked at the 
nearest authorized Mercedes-Benz 
Center.
