opened or have reached the desired
position. The indicator lamp on the

The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
In addition, the air conditioning dehumidi-
fies the interior air at outside temperatures
above 41°F (5° C) and helps prevent
window fogging.

tioning (cooling) function of the climate

then no longer be cooled or dehumidified.

The air conditioning uses the refrigerant

which are harmful to the ozone layer.

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 inte-
rior 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.
