otherwise fog up.
To preven tthe windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof
closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 141).
i Ventilate the vehicle for abrief period
during warm weather, e.g. using the
convenience opening feature (Y page 89).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly. i
The integrated filter filters out most
particles of dust and soot and completely
filters out pollen. It also reduces gaseous
pollutantsa nd odors.Aclogged filter
reduces the amoun tofair supplied to the
vehicle interior .For this reason, you should
always observe the interval for replacing
the filter, which is specified in the
Maintenance Booklet .Asitdepends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet. 130
