avoid misting.
•
If misting occurs, you should deactivate
the air quality sensor.

If misting occurs, you can use the defroster
functions for the windscreen, side win-
dows and rear window.
•
Follow the Volvo service programme for
the recommended replacement interval of
the Multifilter. If the car is used in environ-
ments where more contaminants are pres-
ent, it may be necessary to change the
Multifilter more often.
3. Recirculation
Recirculation can be used to shut out bad air,
exhaust, etc. from the passenger compart-
ment. The air in the passenger compartment is
:
recirculated, i.e. no outside air is taken into the
car when this function is activated.
If you allow the air in the car to recirculate, there
is a risk of icing and misting, especially in win-
ter.
The timer function (cars with Multifilter and air
quality sensor have no timer function) mini-
mises the risk for ice, misting and bad air.
Activate the function as follows:
1. Press
lamp flashes for 5 seconds. The air recir-
culates in the car for 3-12 minutes depend-
ing on the outside temperature.
