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.

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.

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

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.

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 passen- ger 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 com- partment 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).

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: 1.5 lbs (700 g)

Dual1 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.
