Useful information
i This 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.
i Read the information on qualified special-
ist workshops ( Y
page 25).
Overview of climate control systems
General notesObserve 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.
If you start the engine using your smartphone,
the last selected climate control setting is
reactivated ( Y
page 171). The residual heat function can only be acti-
vated or deactivated with the ignition
switched off ( Y
page 143).
Always keep the ventilation flaps behind the
side trim panel in the cargo compartment
clear ( Y
page 124). Otherwise the vehicle will
not be ventilated correctly.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature ( Y
page 91). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i The 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 t he
Main tenance Booklet.
i It 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.132
