03 Climate

Climate control system – general information
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
window cleaning agent to clean the windows.
03
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
passenger compartment temperature sensor
in the ECC control panel should not be cov-
ered in any way as this could cause incorrect
information 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* for several minutes before driving
will help release the warm air from the pas-
senger compartment. When the engine is run-
ning, 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 recom-
mend that you manually adjust the tempera-
ture 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
technician.
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: 1.5 lbs (700 g)
Dual 1 A/C system: 2.2 lbs (1000 g)
The system also uses PAG oil.
