224 Controls in detail4-zone automatic climate control
The climate control is a 4-zone intelligent
climate control system. Your vehicle interi-
or is divided into 4 zones.With the help of a sun sensor, the climate
control determines the relation of the sun
to the vehicle and automatically adjusts
the inside temperature for every individual
zone.
You can set the temperature for each of
the 4 zones separately.
The climate control is operational whenev-
er the engine is running. It cools the vehi-
cle’s interior according to the angle and
intensity of the sun’s rays, the outside tem-
perature and the selected temperature.
You can operate the climate control sys-
tem in either the automatic or manual
mode.
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burn or frostbite to unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary, use the air distribu-
tion controls (
page 222) or (
page 223)
to direct the air to air vents in the vehicle in-
terior that are not in the immediate area of
unprotected skin.

225 Controls in detail
4-zone automatic climate control
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the A/Cmode (
page 234) is
deactivated.Deactivating the climate control
system
Deactivating
Press button´ (
page 222) or
(
page 223) until the display4
(page 222) or (
page 223) is
cleared.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
i
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before its
scheduled interval. A clogged filter will reduce
the air volume to the interior.
If the vehicle interior is hot, ventilate the interior
before driving off, see “Summer opening fea-
ture” (page 239). The climate control will then
adjust the interior temperature to the set value
much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.
Do not obstruct air flow by placing objects on the
air flow-through exhaust slots below the rear
window.
Warning!
G
When the climate control is switched off, the
outside air supply and circulation are also
switched off. Only choose this setting for a
short time. Otherwise the windows could
fog up, impairing visibility and endangering
you and others.
