Automatic climate control* (Canada only)
Air conditioning
The cooling function, only operational 
when the engine is running, cools the vehi-
cle interior down to the selected tempera-
ture. The cooling function also 
dehumidifies the air in the vehicle interior, 
thus preventing the windows from fogging 
up.
Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic 
climate control system. The air in the 
vehicle will then no longer be cooled or 
dehumidified.

Warning!

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.

If the air conditioning cannot be turned 
on again, this indicates that the air 
conditioning is losing refrigerant. The 
compressor has turned itself off.
Have the air conditioning checked at 
the nearest authorized Mercedes-Benz 
Center.
