Switching air-recirculation mode
on/off
General notes
You can also temporarily deactivate the flow
of fresh air manually if unpleasant odors are
entering the vehicle from outside. The air
already inside the vehicle will then be recir-
culated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
Activating or deactivating
XTurn the SmartKey to position 2in the igni-
tion lock (
Ypage 151).
XTo activate: press thegrocker switch
up or down.
The indicator lamp in the grocker
switch lights up.
Air-recirculation mode is automatically acti-
vated at high levels of pollution or at high out-
side temperatures. The indicator lamp in the
g rocker switch is not lit when automatic
air-recirculation mode is activated. Outside
air is added after about 30 minutes.
XTo deactivate: press thegrocker
switch up or down.
The indicator lamp in the grocker
switch goes out. Air-recirculation mode deactivates automati-
cally:
Rafter approximately five minutes at outside
temperatures below approximately 41 ‡
(5 †)
Rafter approximately five minutes if cooling
with air dehumidification is deactivated
Rafter approximately 30 minutes at outside
temperatures above approximately 41 ‡

tion" function is activated
Switching the residual heat on or off
General notes
Once the engine is switched off, it is possible
to make use of the residual heat of the engine
to continue heating or ventilating the front
compartment of the vehicle for approximately
30 minutes.
The heating or ventilation time depends on
the temperature that has been set.
