200 Controls in detailDual-zone automatic climate controlThe climate control is operational whenev-
er the engine is running. You can operate
the climate control system in either the au-
tomatic or manual mode. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.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 AC
OFF
mode is activated or
AC mode is deactivated (
page 206).
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents in the footwell can be
very hot or very cold (depending on the set
temperature). This may cause burns or frost-
bite to unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected parts of the
body and the footwell air vents. If necessary
change the air flow using the air distribution
controls (
page 198) to direct the air away
from the footwell air vents.
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.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter 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.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.

212 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. These settings can
be assigned to a SmartKey and stored in
memory (
page 176).
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.
