1
(Defrost): This mode clears the windows of fog
or frost more quickly. Air is directed to the windshield,
with a small amount directed to the side window outlets.
The indicator light comes on and the digital display will
show the defrost mode symbol and fan speed when
the front defrost mode is being used. In this mode, the
system automatically turns off the recirculation and runs
the air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode. Pressing
1
again
will return the system to the last operating mode.
For severe ice conditions, turn the driver’s temperature
knob to 90°F (32°C) while in defrost mode.
Do not drive the vehicle until all the windows are clear.
^
(Air Conditioning Off): Press to turn the air
conditioning compressor off. Press AUTO to return to
automatic operation. When in AUTO, the air conditioning
compressor comes on automatically, as needed.
Air conditioning does not operate at temperatures
below about 35°F to 40°F (2°C to 4°C). In temperatures
above 40°F (4°C), the air conditioning cannot be
turned off in defrost and defog, as it helps to remove
moisture from the vehicle. It also helps to keep the
windows clear.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts 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.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to 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 press the AUTO button
and adjust the temperature to a cool, comfortable setting.
To achieve maximum cool down, do the following:
1. Select
H
mode.
2. Press
?
.
3. Select the a/c on.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
the vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so a small amount of water might drip under
the vehicle while idling or after turning off the engine.
This is normal.
