2004 VOLVO XC90
Acceleration
The air conditioning is momentarily disengaged during full-throttle acce\
leration.
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 v\
ehicle 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 ma\
y 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 runni\
ng.
However, when the engine is switched off (even if the ignition is switc\
hed to positions I or II), the blower control will be
automatically switched off to avoid unnecessary battery drain. The follo\
wing points pertain if the ignition key is on but the
engine is not running:
l To restart the blower, turn the control knob to the setting of your choi\
ce.
l 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 sys\
tem has been designed to reduce the blower's speed
again after 2 minutes, until the engine is started. If the battery becom\
es drained:
l LOW BATTERY, FAN IS REDUCED will be displayed in the text window in the \
instrument panel.
l The yellow warning light in the instrument panel (see page 25) will also light up.
