Climate control

Useful information
iThis Operator's Manual describes all
models and all standard and optional equip- ment 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.
iRead the information on qualified special-
ist workshops ( Ypage 24).
Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the 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 dehumidifi-
cation function
R switch on the defrost windshield function
briefly, if required
The air-conditioning system/dual-zone auto-
matic climate control regulates the tempera- ture and the humidity of the vehicle interior
and filters out undesirable substances from
the air.
The air-conditioning system/dual-zone auto-
matic climate control can only be operated
when the engine is running. Optimum opera-
tion is only achieved with the side windows
and panorama roof with power tilt/sliding
panel closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off ( Ypage 130).
Always keep the ventilation flaps behind the
side paneling in the cargo compartment clear. Otherwise the vehicle will not be ventilated
correctly.
iVentilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature ( Ypage 82). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
iThe integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol- lutants and odors. A clogged 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.
iIt is possible that under certain circum-
stances the residual heat function may be
activated automatically an hour after the
SmartKey has been removed in order to dry the automatic climate control. The vehicle
is then ventilated for 30 minutes.
