Activating/deactivating air-
recirculation mode
Points to observe before use
You can deactivate the flow of fresh air if
unpleasant odors are enteringthe vehicle
from outside. The air already inside the
vehicle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in
particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.
The operation of air-recirculation mode is the
same for all control panels.
Activating/deactivating
XTurn the SmartKey to position2in the
ignition lock (Ypage 137).
XTo activate:press thebutton.
The indicator lamp in thebutton lights
up.
iAir-recirculation mode is activated
automatically at high outside
temperatures. When air-recirculation mode
is activated automatically, the indicator
lamp in thebutton is not lit.
Outside air is added after about
30 minutes.
XTo deactivate:press thebutton.
The indicator lamp in thebutton goes
out.
iAir-recirculation mode deactivates
automatically:
Rafter approximately five minutes at
outside temperatures below
approximately 41 ‡ (5 †)
Rafter approximately five minutes if the
"Cooling with air dehumidification"
function is deactivated
Rafter approximately 30 minutes at
outside temperatures above
approximately 41‡(5†) if the "Cooling
with air dehumidification" function is
activated
Activating/deactivating the residual
heat function
The residual heat function is only available in
vehicles for Canada with automatic climate
control.
It is possible to make use of the residual heat
of the engine to continue heating the vehicle
for approximately 30 minutes after the engine
has been switched off. The heating time
depends on the temperature that has been
set.
iThe blower will run at a low speed
regardless of the airflow setting.
iIf you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.

Setting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air
outlets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet between the windshield
and the hood free of blockages, such as ice,
snow or leaves.
Rnever cover the air vents or air intake grilles
in the vehicle interior.
iYou can move the adjusters for the air
vents vertically or horizontally to set the
direction of the airflow.
iFor optimal climate control in the vehicle,
open the air vents completely and set the
adjusters to the central position.
Setting the center air vents
XTo open the center air vent:turn the
adjuster in one of center air vents
