,
button or by pressing
the respective window switch. The closing of
the sliding/pop-up roof can be immediately
halted by releasing 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.

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

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.

armrest
The storage compartment under the arm-
rest (
page 200) can be ventilated when
the automatic air conditioning is switched
on. The switch is located inside the storage
compartment in the front. The air tempera-
ture is about the same as that of the center
air vents.
The air volume is dependent on the setting
of:


Air distribution control


Air volume control


Air vents in the dashboard
The air temperature is about the same as
that of the dashboard air vents. It cannot
be regulated separately.
iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting1 regardless of the air distribu-
tion control setting.
