Operation
Press to activate the air
quality sensor (normal setting).
Or:
Select one of the following three functions by
pressing repeatedly.
• AUT LED lit: The air quality sensor is now
activated.
• No LED lit: Recirculation is not activated
unless needed to cool in a warm climate.
• MAN LED lit: Recirculation is now
activated.
Keep in mind the following:
• Make it a rule to have the air quality
sensor activated at all times.
• Recirculation is limited in cold weather to
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 windows and rear window, see
page 67.
• Follow the Volvo Service Programme for
the recommended replacement interval of
the Multifilter. If the car is used in a
severely contaminated environment, it
may be necessary to change the Multi-
filter more often.
3. Recirculation
Recirculation can be used to shut out bad air,
exhaust, etc. from the passenger
compartment. The air in the passenger
compartment is then recirculated, i.e. no air
from outside the car 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)
minimises the risk for ice, misting and bad air.
Activate the function as follows:
– Press for more than 3 seconds.
The LED flashes for 5 seconds. The air
recirculates in the car for 3-12 minutes
depending on the outside temperature.
– The timer function is activated each time
you press .
To switch off the timer function:
– Press again for more than
3 seconds. The LED lights for 5 seconds
to confirm your selection.
Recirculation is always disconnected when
you select Defroster.
Climate control
4. AUTO
The AUTO function automatically regulates
climate control so that the desired temper-
ature is attained. The automatic function
controls heating, air conditioning, fan speed,
recirculation, and air distribution. If you select
one or more functions manually, the other
functions continue operating automatically.
All manual settings are switched off when
AUTO is switched on.
5. Air distribution
• When the top button is depressed, air is
directed to the windows.
• When the centre button is depressed, air
is directed to the head and body.
• When the lower button is depressed, air
is directed to the legs and feet.
Press AUTO to return to automatic air distri-
bution.
6. Passenger compartment
temperature sensor
The passenger compartment temperature
sensor monitors the temperature inside the
car.
7. Defroster, windscreen and
side windows
Use this button to quickly remove misting and
ice from the windscreen and side windows.
