The ventilation system always allows fresh air to flow
through your vehicle when the vehicle is moving even
with the system in the OFF mode.

VENT: The VENT button allows outside air to flow
through your vehicle without the air conditioning
compressor working. Selecting VENT and the AUTO
button at the same time allows the system to control
automatically without the use of the air conditioning
compressor or the use of the RECIRC mode. To turn off
the VENT selection, push the VENT button again.

RECIRC: When RECIRC is selected, the system will
limit the amount of outside air entering your vehicle. This
is helpful when you are trying to cool the interior of the
vehicle quickly or limit the amount of outside air entering
your vehicle. RECIRC and AUTO may be selected at the
same time. The system will remain in RECIRC until the
ignition is turned off, then the system will return back to
the previously selected mode. Deselecting the RECIRC
button will also turn off the RECIRC function. RECIRC
can be selected in all manual airflow modes except
FRONT defrost and VENT.

FRONT: This selection is used to defrost the windshield
by directing the airflow toward the windshield.

If FRONT is selected while in the AUTO mode, the fan
speed and the air temperature from the front defroster will
vary. If a manual fan speed setting is selected, the fan
speed will remain at that selection until another fan speed
selection is made or the AUTO mode is selected. To turn
off FRONT, press the AUTO or AIR FLOW button.

FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.

Air Conditioning

On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.

If you have the electronic touch system, for quick
cool

-

down on very hot days, use MAX with the

temperature and fan speed adjusted to COOL and
HIGH. If this setting is used for long periods of time, the
air in your vehicle may become too cold and dry.

For normal cooling on hot days, use NORM and adjust
the temperature and fan speed for your comfort. If
RECIRC is selected while in the NORM air
conditioning mode, the system works like MAX and
recirculates the air.
