To cool your vehicle using outside air, turn the
SELECT control to A/C, turn the TEMP control
all the way to the end of the blue range (full
left) and turn the FAN control to the desired
speed between LO and HI. A/C provides quieter
system operation than MAX A/C, but it is not
as efficient as MAX A/C which uses recirculated
air.
To ventilate your vehicle with outside air,
during mild weather, turn the SELECT control to
PANEL, turn the TEMP control for the
temperature desired and set the FAN control to
the speed desired.
Under normal conditions, the SELECT control
should be left in any position other than MAX
A/C or OFF when the vehicle is parked. This
allows the vehicle to "breathe" through the
outside air inlet duct.
To cool your vehicle quickly in warm weather,
turn the SELECT control to MAX A/C, turn the
TEMP control all the way to the end of the blue
range (full left) and turn the FAN control to HI.
MAX A/C uses recirculated air and is the most
fuel efficient way to cool your vehicle and can
also be used in heavy traffic to prevent exhaust
fumes from entering the vehicle. MAX A/C can
also be used in high humidity areas for more
efficient operation.
If the interior of your vehicle is very warm,
drive for the first few minutes with the windows
open. This forces most of the hot, stale air out of
the vehicle and allows the air conditioning to
work faster.
