3-zone automatic climate control*
Convenience opening:
Press and hold button
: until the 
windows and the tilt/sliding panel are 
opened or have reached the desired 
position. The indicator lamp on the 
button goes out. The air recirculation 
mode is deactivated.
Air conditioning
The cooling function, only operational 
when the engine is running, cools the 
vehicle down to the selected interior 
temperature. The cooling function also 
dehumidifies the air in the vehicle interior, 
thereby 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.

The indicator lamp on the button

The air conditioning uses the refrigerant

which are harmful to the ozone layer.
i
Condensation may drip out from underneath 
the vehicle. This is normal and not an indication 
of a malfunction.
Warning!
G
If you turn off the cooling function, the 
interior air is not dried. 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 
off.
Have the air conditioning checked at the nearest 
authorized Mercedes-Benz Light Truck Center.
