Condensation on the inside of the
windows
Keeping the insides of the windows clean will
help reduce the amount of condensation that
forms on the windows. Use a commercial win-
dow cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of
the windshield free of snow.
Cabin air filter
Replace the cabin air filter with a new one at
the recommended intervals. Please refer to
your Warranty and Service Records Informa-
tion booklet, or consult a trained and qualified
Volvo service technician for these intervals.
The filter should be replaced more often when
driving under dirty and dusty conditions. The
filter cannot be cleaned and therefore should
always be replaced with a new one.
Sensors
The sunlight sensor on the dashboard and pas-
senger compartment temperature sensor in
the ECC control panel should not be covered
in any way as this could cause incorrect infor-
mation to be sent to the ECC system.
Parking the vehicle in warm weather
If your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof (option) for several minutes before
driving will help release the warm air from the
passenger compartment. When the engine is
running, close the windows and moonroof and
use the recirculation function for several
minutes to enable the air conditioning to cool
the compartment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the win-
dows and optional moonroof are closed. If you
drive with the moonroof open, we recommend
that you manually adjust the temperature and
blower control (the LED in the
AUTO switch
should be off).
Acceleration
The air conditioning is momentarily disen-
gaged during full-throttle acceleration.
Climate control maintenance
Special tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.
Refrigerant
Volvo cares about the environment. The air
conditioning system in your vehicle contains a
CFC-free refrigerant – R134a (HFC134a). This
substance will not deplete the ozone layer. The
approximate amount of R134a contained in the
system is a follows:
6-cylinder engine
Single A/C system: 1.4 lbs (700 g)
Dual
1
A/C system: 2.2 lbs (1000 g)
8-cylinder engine
Single A/C system: 1.5 lbs (700 g)
Dual
1
A/C system: 2.3 lbs (1050 g)
The system also uses PAG oil.
