The air-conditioning system is a combination of
a heating and ventilation system and a cooling
system.
Recommendations for optimal climate control:
R
Set the temperature to 22 †. Only change the
temperature in small increments.
R
Switch cooling or cooling with air dehumidifi-
cation on. The indicator lamp in the
¿
or
Á
button lights up.
R
Air-conditioning system with residual engine
heat utilisation: after long journeys, use the
residual heat of the engine to heat the sta-
tionary vehicle. The indicator lamp in the
Á
button lights up.
R
Only use demisting mode until the misted
windscreen is clear again (
Y
page 121).
R
Only use air-recirculation mode briefly, e.g. if
there are unpleasant odours or in dusty con-
ditions. The windscreen and the window may
otherwise mist up as the flow of fresh air is
deactivated and the air inside the vehicle is
circulated.

Heating with auxiliary heating is a heating and
ventilation system without a cooling system.
The air-conditioning system with auxiliary heat-
ing is a combination of a heating and ventilation
system, a cooling system and an auxiliary heat-
ing system.
Recommendations for optimal climate control:
R
Set the temperature to 22 †. Only change the
temperature in small increments.

Air conditioning: switch cooling or cooling
with air dehumidification on. The indicator

After long journeys, use the residual heat of
the engine to heat the stationary vehicle. The
indicator lamp in the
