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 24). Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could other-
wise 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
sliding sunroof is open. The automatic climate control cannot maintain the set temperature
with the sliding sunroof open. You have to
adjust the climate control manually.
i The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 127).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 78). 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. 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. 118

control
The following contains notes and recommen-
dations on optimum use of dual-zone climate control.
R Activate climate control using the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the defrosting function briefly
until the windshield is clear again.
R Only 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.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp in the ábutton goes out. 120
