159 Controls in detail
Automatic climate control
Automatic climate control panel
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 the AC
OFF
mode is selected
(
page 166).

Follow the recommended settings for heat-

es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.

160 Controls in detailAutomatic climate control
Setting the temperature
Use temperature controls (
page 159)
10for the left side or8 for the right side to
separately adjust the air temperature on
each side of the passenger compartment.
You should raise or lower the temperature
setting in small increments, preferably
starting at 72°F (22°C).
Increasing / decreasing

Press button 10 or 8 repeatedly up or
down until the display shows the de-
sired temperature.
The automatic climate control system
will accordingly adjust the interior air
temperature.Adjusting the temperature for center
air vents
When outside temperatures are low, you
can manually raise the air temperature for
the center and side air vents. The
thumbwheel4 is located between the cen-
ter air vents (
page 157).
Automatic temperature control

Turn thumbwheel 4 to A.
The indicator lamp above the thumb-
wheel lights up. The temperature is au-
tomatically adjusted to the set value.
Turning on warm air

Turn thumbwheel4 in the direction of
the white marking.
Warm air will enter from the center air
vent.
iThe current climate control settings
(ON / OFF, temperature, air volume, ac-
tivated charcoal filter, etc.) are stored
for each electronic key before it is re-
moved from the starter switch or when
the vehicle is locked using the
KEYLESS-GO* card (
page 105).
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, leaves, sticks
and any other debris.
Do not obstruct air volume by placing
objects on the air volume-through ex-
haust 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.

163 Controls in detail
Automatic climate control
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside. This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment.
Activating
Press button
,
(page 159).
The indicator lamp on the button lights
up.
Warning!
G
When the outside temperature is below
41°F (5°C), only switch to air recirculation
mode for short periods to prevent window
fogging.iIf you keep button
,
pressed, the
side windows and the sliding / pop-up
roof will be closed.
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 pro-
cedure.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by
releasing the
,
button or by pressing
the respective window switch. The closing of
the sliding/pop-up roof can be immediately
halted by releasing the
,
button or by
moving the sliding/pop-up roof switch in the
overhead control panel in any direction.
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 beyond a
predetermined level, for example in
a tunnel.
Please note that the charcoal filter
must be activated (
page 164) for the
air recirculation mode to be activated
automatically.
If you have turned off the air condition-
ing (
page 166) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch
on automatically.

(page 159).
The indicator lamp on the button goes

The air recirculation mode is deactivated
automatically:


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


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside temper-
ature 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.
Charcoal filter
An activated charcoal filter markedly re-
duces bad odors and removes pollutants
from air entering the passenger compart-
ment.

165 Controls in detail
Automatic climate control
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, for example
in a tunnel.
The automatic air recirculation mode does
not function if AC
OFF
m o d e i s s e l e c t e d o r i f
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.
Rear window defroster
The rear window defroster uses a large
amount of power. To keep battery drain to
a minimum, switch off the defroster as
soon as the rear window is clear. The de-
froster is automatically deactivated after
approximately 6 to 17 minutes of opera-
tion depending on the outside tempera-
ture.
Activating
Press button
F
(page 159).
The indicator lamp on the button lights
up.
Deactivating

Press button
F
(page 159) again.
The indicator lamp on the button goes
out.
iIf you keep button
e
pressed, the
side windows and the sliding / pop-up
roof will be returned to their previous
positions.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.!If the rear window defroster switches
off too soon and the indicator lamp
starts blinking, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.
