2007 Volvo XC90
Windows and optional moonroof
The ECC system will function best if the windows 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 disengaged 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: 1.4 lbs (620 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.
Climate system blower
The climate system blower will be automatically switched off when the engine is not running (even if the ignition
key is in position I or II) to avoid unnecessary battery drain. To activate the blower, turn the control to the desired
setting.
Passenger compartment blower
Approximately 50 minutes after the ignition is turned off, the blower may come on automatically, and run for
seven minutes, to remove condensation in the A/C evaporator.
