Outside temperature

174 Controls in detailClimate controlThe climate control is operational when-
ever the engine is running. You can oper-
ate the climate control system in either the
automatic or manual mode. The system
cools or heats the interior depending on
the selected interior temperature and the
current 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 modeAC
OFF
is activated or
mode A/C is deactivated (page 179).
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 on 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 to direct the air away from the foot-
well air vents (
page 176).
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
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
“Opening (Summer opening feature)”
(page 240).
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing
objects on the air flow-through exhaust
slots below the rear window.

ments, preferably starting at 72°F (22°C).Increasing

spondingly adjust the interior air tem-
perature.

spondingly adjust the interior air tem-
perature.
iWhen the air conditioning is switched

this setting for a short time. Otherwise
the windows could fog up.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.
