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.
Interior Air Quality system (option)
Some cars are equipped with a multifilter and air quality sensor. The filter separates gases and
particles, thereby reducing the amounts of odors and contaminants entering the car. The air quality
sensor detects increased levels of contaminants in the outside air. When the air quality sensor detects
contaminated outside air, the air intake closes and the air inside the passenger compartment is
recirculated, i.e. no outside air enters the car. The filter also cleans recirculated passenger
compartment air. When the Air quality sensor is activated, the LED AUT comes on in the
recirculation button
Operations:
Press
to activate the Air quality sensor (normal setting). Or select one of three functions by
pressing
1. Press
the LED
AUT
comes on. The Air quality sensor is now activated.
