Useful information
i
This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific 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 specialist
workshops: (Ypage 23).
Overview of climate control systems
Important safety notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up. This could prevent you from observing the
traffic conditions, thereby causing an accident.
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Dual-zone automatic climate control is only
operational when the engine is running. Opti-
mum operation is only achieved if you drive with
the side windows and sliding sunroof closed.
The climatic comfort deteriorates whilst the slid-
ing sunroof is open. The automatic climate con-
trol cannot maintain the set temperature with
the sliding sunroof open. You have to adjust the
climate control manually.
iThe residual heat function can only be acti-
vated or deactivated with the ignition
switched off (
Ypage 108).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 68). This will speed
up the cooling process and the desired vehi-
cle interior temperature will be reached more
quickly.
iThe integrated filter can filter out most par-
ticles of dust, and completely filters out pol-
len. A clogged filter reduces the amount of air
supplied to the vehicle interior. For this rea-
son, 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 pol- lution, the interval may be shorter than stated
in the Maintenance Booklet.

Optimum use of dual-zone climate
control
The following contains notes and recommenda-
tions on optimum use of dual-zone climate con-
trol.
RActivate climate control using theÃand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
RSet the temperature to 72 ‡ (22 †).
ROnly use the defrosting function 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 otherwise fog up, since no fresh air is drawn into the vehicle in
air-recirculation mode.
RUse the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side as well. The indicator
lamp in the
ábutton goes out.
