Useful information
This Operator's Manual describes all models
as well as standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific variations
are possible. Note that your vehicle may not
be equipped with all of the described
functions. This also applies to systems and
functions relevant to safety.
Read the information on qualified specialist
workshops (Y page 26). Overview of climate control systems
Important safety notes
Observe the recommended settings on the
following pages. Otherwise, the windows
could fog up.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
i Ventilate the vehicle for a brief period
during warm weather. In order to cool the
vehicle more rapidly, switch climate control
to air-recirculation mode briefly. This will
speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the airflow
into the vehicle interior .For this reason,
you should always observe the interval for
replacing the filter, which is specified in the
Maintenance Booklet .As it depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet. 108
