Condensation on the inside of the
windowsKeeping 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 snowAlways keep the air intake grille at the base of
the windshield free of snow.Cabin air filterReplace 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.
SensorsThe 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 weatherIf 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 moonroofThe 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).
AccelerationThe air conditioning is momentarily disen-
gaged during full-throttle acceleration.Climate control maintenanceSpecial 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.RefrigerantVolvo 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)
Dual1 A/C system: 2.3 lbs (1050 g)
The system also uses PAG oil.

Climate control system – general information
0391 Climate system blower
The climate system blower will be automati-
cally switched off when the engine is not run-
ning (even if the ignition key is in position I or
II) to avoid unnecessary battery drain. To acti-
vate the blower, turn the control to the desired
setting.
The climate system blower may start automat-
ically during a period of up to approximately
50 minutes after the ignition has been turned
off to remove condensation in the A/C evapo-
rator. It will run for 15 minutes and switch off
automatically.Passenger compartment blowerApproximately 50 minutes after the ignition is
turned off, the blower may come on automati-
cally, and run for seven minutes, to remove
condensation in the A/C evaporator.Blower function to reduce battery drainThe climate system's blower functions nor-
mally while the engine is running.
However, when the engine is switched off
(even if the ignition is switched to positions I or
II), the blower control will be automatically
switched off to avoid unnecessary battery
drain.The following points pertain if the ignition is on
but the engine in not running:
•
To restart the blower, turn the control knob
to the setting of your choice.
•
After approximately 2 minutes, the blower
speed will be reduced to avoid battery
drain.
You can reset the blower speed at any time.
Please be aware that the system has been
designed to reduce the blower's speed again
after 2 minutes, until the engine is started.
If the battery becomes drained:
•
LOW BATTERY, FAN IS REDUCED will
be displayed in the text window in the
instrument panel.
•
The yellow warning light in the instrument
panel (see page 54) will also light up.
