pg. 44 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.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Air cabin filter
Replace the air cabin filter with a new one at the recommended 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 covered in any way as this could cause incorrect information to be sent to the ECC system.
Parking the car in warm weather
If your car has been parked in the sun in warm weather, opening the windows and sun roof (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 sun roof and use the recirculation function for several minutes to enable the air conditioning to
cool the compartment as quickly as possible.
Windows and optional sun roof
The ECC system will function best if the windows and optional sun roof are closed. If you drive with the sun roof
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.
ECC maintenance
All maintenance on the climate control systems should be carried out by an authorized Volvo service technician only.
Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a.
This substance will not deplete the ozone layer. The system contains 2.2 lbs (1000 g) R134a and uses PAG oil.
Passenger compartment blower
The blower may come on automatically (certain models) after approximately 50 minutes, and stay on for 5 minutes, to
remove excess condensation in the A/C evaporator.
