Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.

The air conditioning system uses the refrig-
erant R-134a. This refrigerant is free of
CFCs which are harmful to the ozone layer.
iTo achieve the fastest possible cooling
of the interior, the automatic climate
control automatically switches to air
recirculation. The indicator lamp in the
buttonÄ is not illuminated when
the system automatically switches to
air recirculation.
iThe air recirculation mode is
deactivated automatically
after 30 minutes if the automatic
climate control is switched on
after five minutes if the air condi-
tioning is switched off
after five minutes if the outside
temperature is above approximate-
ly 45°F (7°C)
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.

checked at the nearest authorized
Mercedes-Benz Light Truck Center.
iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at lower
speed regardless of the air volume con-
trol setting.
iThe residual heat is automatically
turned off:
when the ignition is switched on
after about 30 minutes
if the coolant temperature is too
low
if the battery voltage drops
