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.  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
Approximately 50 minutes after the ignition is turned off, the blower may come on automatically,  and  run for five
minutes, to remove condensation in the A/C evaporator.
