Air conditioning

The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
i
Condensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.

tioning (cooling) function of the automatic

cle will then no longer be cooled or dehu-
midified.

goes out.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
!
If button ± on the automatic cli-
mate control panel starts to flash, this
indicates that the air conditioning is
losing refrigerant. The compressor has
turned itself off. The air conditioning
cannot be turned on again.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.
