(Air Conditioning): Press to turn the air conditioning
system on or off. An indicator light comes on to show
that the air conditioning is on. This setting cools
and dehumidifies the air entering the vehicle.
The air conditioning does not work if the fan is turned
off. If air conditioning is selected with fan off, the
indicator light flashes three times and then turns off.
There could be a slight change in engine performance
when the air conditioning compressor turns off and turns
on again. This is normal. The system is designed to
make adjustments to help with fuel economy while still
maintaining the selected temperature.
Air conditioning does not operate at temperatures below
40°F (4°C). In temperatures above 40°F (4°C), the air
conditioning cannot be turned off in defrost, floor/defog,
and recirculation modes because it helps to remove
moisture from the vehicle. It also helps to keep
the windows clear.
On hot days, open the windows to let the hot inside air
escape; then close them. This helps reduce the time
it takes for the vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select

.
2. Select

3. Select the air conditioning to on.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
can cause the air inside of the vehicle to become too dry.
To prevent this from happening, after the air in the vehicle
has cooled, turn the recirculation mode off.
