2005 VOLVO XC90
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.
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).
Acceleration
The air conditioning is momentarily disengaged during full-throttle acceleration.
Climate control 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 vehicle contains a CFC-free
refrigerant - R134a (HFC134a). 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 seven minutes, to remove condensation in the A/C evaporator.
Blower function to reduce battery drain
The climate system's blower functions normally while the engine is running.
However, when the engine is switched off (even if the ignition is switched to positions I or II), the blower
control will be automatically switched off to avoid unnecessary battery drain.
The following points pertain if the ignition key is on but the engine is not running:
●
To restart the blower, turn the control knob to the setting of your choice.
●
After approximately 2 minutes, the blower speed will be reduced to avoid battery drain.
You can reset the blower speed at any time. Please be aware that the system has been designed to reduce the
blower's speed again after 2 minutes, until the engine is started. If the battery becomes drained:
●
LOW BATTERY, FAN IS REDUCED will be displayed in the text window in the instrument panel.
●
The yellow warning light in the instrument panel (see
page 27
) will also light up.
