Mode Buttons
(Outside Air): Press this button to send outside
air into your vehicle. The light in the button will glow
when outside air is in use. Using this setting while trying
to defrost or defog the windows will help clear the vents
of moisture. While floor, defog or defrost mode is
selected, the system will automatically go to outside air
mode.
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. The light in
the button will glow when recirculation is in use. You
may use this setting to limit odors entering your vehicle.
Operating the Heating/Ventilation/Air Conditioning
(HVAC) system in the recirculation mode may cause
fogging of the vehicle’s windows when the weather is
cold and damp. To clear the fog, switch the HVAC
system to either the defog or defrost mode and increase
the fan speed. To avoid re
- fogging of the windows,
operate the HVAC system in the outside air mode.
A/C (Air Conditioning): Press this button to turn
the air conditioning compressor on and off. The light in
the button will glow when the air conditioning is in use.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows
long enough to let hot, inside air escape. For all
settings, adjust the temperature control knob and fan
speed as desired.
To get maximum cooling or a quick cool - down on very
hot days, press the A/C and recirculation buttons and
move the temperature control toward the blue area.
Adjust the mode knob to direct the air to the desired
location. This setting should not be used for long
periods of time because the air may become too cold
and dry. Push the A/C button again to turn off the
air conditioning.
When the air conditioner compressor is on, you may
sometimes notice slight changes in your vehicle’s engine
performance and power. This is normal. The system is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air, so
you may sometimes notice water dripping from under
your vehicle’s engine compartment when it is idling or
after it has been turned off. This is normal.
