DEFOG: This setting directs air to the windshield
and through the floor ducts. This mode is useful during
cold or inclement weather because of your vehicle’s
larger windshield area.
DEFROST: This setting directs most of the air
to the windshield and side window vents.
Mode Buttons
OUTSIDE AIR: Press this button (the light will
glow) to send outside air into your vehicle. Using this
setting while trying to defrost or defog the windows
will help clear the vents of moisture. Press the
RECIRCULATION button (the light on the OUTSIDE
AIR button will go off) to limit outside air entering the
vehicle. When the DEFOG or DEFROST setting is
selected, the system will automatically go to
OUTSIDE AIR mode.
RECIRCULATION: Press this button (the light
will glow) to limit the amount of fresh air entering your
vehicle by recirculating much of the air inside your
vehicle. You may use this setting to limit odors entering
your vehicle. Press the OUTSIDE AIR button (the light
on the RECIRCULATION button will go off) to let
outside air circulate into the 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.
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
(the lights will glow) and turn the temperature knob
counterclockwise (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 (the light will go off) to turn off the
air conditioning.
