Operation
Air recirculation mode
Basic points
Air recirculation:
Manual recirculation
Air recirculation mode prevents the ambient
air from ent
ering the interior.
When the outside temperature is very high,
selecting manual air recirculation mode for a
short period refreshes the vehicle interior
more quickly.
For safety reasons, air recirculation mode is
switched off when the button is press-
ed or the air distributor turned to .
Switching the manual air recirculation mode
on and off
To switch system on: press the button un-
til the warning lamp lights up.
To switch system off: press the button un-
til the warning lamp goes off.
Functioning mode of automatic air recircula-
tion (air conditioning menu)
With the automatic air recirculation mode ac-
tivated, the entry of fresh air into the cabin
interior is enabled. If the system detects a
high concentration of hazardous substances
in the ambient air, air recirculation mode is
switched on automatically. When the level of
impurities drops to within a normal range, re-
cir
culation mode is switched off.
The system is unable to detect unpleasant
smells.
The air recirculation will not connect auto-
matically in versions without humidity sensor
and in the following external conditions:
●
The outside temperature is lower than +3°C
(+38°F).
●
The cooling system is switched off and the
outside temperature is below +10°C (+50°F).
●
The cooling system is switched off, the out-
side temperature is below +15°C (+59°F) and
the windscreen wipers are switched on.
Activation/deactivation of automatic air recir-
culation is done in the air conditioner menu,
under Configuration.
