Introduction

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 28).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could
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 is only operational when the
engine is running. The system only works
optimally when the side windows and the roof
are closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 157).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 93).
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 amount
of air 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 .As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet.
i It is possible that the dehumidification
function of the climate control system may
be activated automatically an hour after the
SmartKey has been removed. The vehicle
is ventilated for 30 minutes. 142
