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 Sensors The sunlight sensor on the dashboard and passenger compartment temperature sensor in the ECC control panel should not be covered in any way as this could cause incorrect information to be sent to the ECC system. 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. Ice and snow Always keep the air intake grille at the base of the windshield free of snow. 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. Cabin air filter Replace the cabin air filter with a new one at the recommended intervals. Please refer to your Warranty and Service Records Information 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. 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) 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. 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). 1 Includes the optional rear A/C system 90
