If misting occurs, you can use the
defroster functions for the windscreen,
side windows 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
present, 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 winter.
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
for more than 3 seconds.
The lamp flashes for 5 seconds. The air
recirculates in the car for 3-12 minutes
depending on the outside temperature.
2. The timer function is activated each time
you press
To switch off the timer function:

4. AUTO
The AUTO function automatically regulates
climate control and maintains the selected
temperature. The automatic function controls
heating, air conditioning, air quality sensor,
fan speed, recirculation and air distribution. If
you select one or more manual functions, the
other functions continue to be controlled
automatically. All manual settings are
switched off when AUTO is switched on.
