Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.

tioning (cooling) function of the automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.

which are harmful to the ozone layer.
i
Condensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
i
Under certain circumstances, e.g.
when the fuel system is too hot and
needs to be cooled, the cooling switch-
es on again automatically. The red lamp
on the ± button the automatic cli-
mate control panel flashes.
After cooling the fuel system sufficient-
ly, the air conditioning switches off
again and the red lamp stops flashing.

If you press the ± button on the au-
tomatic climate control panel and it
starts to flash, this indicates that the
air conditioning is losing refrigerant.
The compressor has turned off. The air
conditioning cannot be turned on
again.

the nearest authorized Mercedes-Benz
