Useful information
These Operating Instructions describe all the
models and standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific differences are
possible. Bear in mind that your vehicle may not
be equipped with all the functions described.
This also applies to safety-relevant systems and
functions.
Read the information on qualified specialist
workshops (Y page 31).
General notes
H
Environmental note
Only switch on the cooling with air dehumidi-
fication function for air conditioning or auto-
matic climate control when necessary. Fuel
consumption increases when the function is
switched on.
The heating/air-conditioning system/auto-
matic climate control can only be operated
when the engine is running.
In order to ensure optimum functioning, close:
R
the windows
R
the sliding sunroof
R
the pop-up roof
R
the roof hatch
The air-conditioning system/automatic climate
control regulates the temperature and humidity
of the cab and filters out undesirable substan-
ces from the air.
The integrated filter largely filters out dust par-
ticles, pollen and unpleasant odours from the air
drawn in from outside or recirculated air in recir-
culation mode. A blocked filter reduces the
amount of air supplied to the cab.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci-
fied.
i
Ventilate the vehicle for a brief period during
warm weather. This will speed up the cooling
process and the desired interior temperature
will be reached more quickly.

The heating system is a heating and ventilation
system without a cooling system.
Recommendations for optimal climate control:
R
Slide the temperature control to the centre
position. Only change the temperature in
small increments.
R
Heating with residual engine heat utilisation:
to heat the stationary vehicle, use the residual
heat of the engine after long journeys. The
indicator lamp in the Ì 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.
