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.
iRead the information on qualified special-
ist workshops (
Ypage 26).
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:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only
briefly
Rswitch on the cooling with air dehumidifi-
cation function
Rswitch on the defrost windshield function
briefly, if required
The automatic climate control regulates the
temperature and the humidity in the vehicle
interior and filters undesirable substances
out of the air.
Dual-zone automatic climate control is only
operational when the vehicle is ready to drive.
Optimum operation is only achieved with the
side windows closed.
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 84). 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.

Optimum use of dual-zone automatic
climate control
Climate control system
The following contains instructions and rec-
ommendations to enable you to get the most
out of your 3-zone automatic climate control.
RActivate climate control using the Ãand
¿ buttons. The indicator lamps in the
à and¿ buttons light up.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RUse the ZONE function to adopt the tem-
perature settings on the driver's side for
