Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e. g. before driving through
a tunnel). This setting cuts off the intake of
outside air and recirculates the air in the pas-
senger compartment.

Warning!
Fogged windows impair visibility, endan-
gering you and others. If the windows begin
to fog on the inside, switching off the air
recirculation mode immediately should
clear interior window fogging. If interior
window fogging persists, make sure the air
conditioning is activated, or press button
y.

Activating: Press button ,.
The indicator lamp in the button comes on.

The air recirculation mode is activated
automatically at high outside temperatures
and if the concentration of carbon monox-
ide (CO) and nitrogen oxide in the outside
air increases, for example in a tunnel.
The indicator lamp in button , is not lit
when the air recirculation mode is auto-
matically switched on.
A quantity of outside air is added after
approximately 30 minutes.

Deactivating: Press button , again.
The indicator lamp in the button goes out.

The manually selected air recirculation
mode is deactivated automatically:
R
after 5 minutes if the outside tempera-
ture is below approximately 41‡ (5†)
R
after 5 minutes if the air conditioning is
turned off
R
after 30 minutes if the outside tempera-
ture is above approximately 41‡ (5†)
Residual heat and ventilation
This feature is only available in Canada vehi-
cles. With the engine switched off, it is pos-
sible to continue to heat or ventilate the
interior for up to 30 minutes. This feature
makes use of the residual heat produced by
the engine.
i
If you switch on the residual heat function
when outside temperatures are high, only
the ventilation will be switched on.
i
Regardless of the selected air volume, the
blower operates at low speed.
i
How long the system will provide heating
depends on the coolant temperature and
the selected temperature. The blower will
run at speed setting 1 regardless of the air
volume control setting.
