156 Controls in detailClimate 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 modeAC
OFF
is selected
(
page 160).
Setting the temperature
Use temperature controls2 and3
(page 155) to separately adjust the air
temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).
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 157).
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.
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.

164 Controls in detailAutomatic climate control*The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing 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 theAC

When operating the automatic 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 frostbite on unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the foot-
well air vents. If necessary, change the air
flow using the air distribution controls to
direct the air away from the footwell air
vents (

Setting the temperature
Use temperature controls1 ande for
the left side or6 and7 for the right side
(page 163) to separately adjust the air
temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).Increasing

Push temperature control1
and/or6.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Decreasing

Push temperature control7
and/ore.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Adding outside air

Turn thumbwheel3 in dashboard
(page 163) to increase airflow of
outside air through air vents for center,
left and right sides and rear passenger
compartment.
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.
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.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.

168 Controls in detailAutomatic climate control*
Deactivating
Press buttonO (
page 163).
The indicator lamp on the button goes
out.The air recirculation mode is deactivated
automatically:


after five minutes if the outside
temperature is below
approximately 41°F (5°C)


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside
temperature is above
approximately 41°F (5°C)
At outside temperatures above 79°F
(26°C) the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
iIf you keep buttonO pressed, the
side windows and the sliding/pop-up
roof* will close.Warning!
G
Never operate the side windows and the
sliding/pop-up roof* if there is the
possibility of anyone being harmed by the
closing procedure.
In the event that the closing procedure
causes potential danger, the closing of the
side windows can be immediately halted by
pressing or pulling the respective window
switch. The closing of the sliding/pop-up
roof* can be immediately halted by moving
the sliding/pop-up roof* switch in the
overhead control panel in any direction.
The closing of the side windows and
sliding/pop-up roof* can be reversed by
again pressing and holding theO button.
iThe air recirculation mode is activated
automatically:

at high outside temperatures


if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases, for example in a
tunnel (charcoal filter activated)
Please note that the charcoal filter
must be activated (
page 169) for
the air recirculation mode to be
activated automatically.
If you have turned off the air
conditioning (
page 170) or the out-
side temperature is below 41°F (5°C),
the air recirculation mode will not
switch on automatically.
iIf you keep buttonO pressed, the
side windows and the sliding/pop-up
roof* will return to their previous
position.

Charcoal filter
An activated charcoal filter markedly
reduces bad odors and removes pollutants
from air entering the passenger compart-
ment.
Activating
Press buttone (
page 163).
The indicator lamp on the button
comes on.
The system switches automatically to the
air recirculation mode if the carbon
monoxide (CO) or nitrogen oxide (NO
X)
concentration of the outside air increases
beyond a predetermined level.Deactivating

Press buttone (
page 163).
The indicator lamp on the button goes
out.
The automatic air recirculation mode does
not function if theAC
OFF
mode is selected
or if the outside temperature has fallen
below 41°F (5°C).
The activated charcoal filter should be
switched off when windows fog up on the
inside, or if the passenger compartment
needs to be quickly heated or cooled
down.
iIf you keep buttone pressed, the
side windows and the sliding/pop-up
roof* will close.
Warning!
G
Never operate the side windows and the
sliding/pop-up roof* if there is the
