To change the current mode, select one of the following:
6
(FLOOR): This mode directs most of the air to
the floor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed
to the windshield.
)
(Bi-Level): This mode directs about half of the air
to the instrument panel outlets, and then directs
most of the remaining air to the floor outlets. There is
also a small amount of air directed to the windshield and
outboard outlets (for the side windows). This mode
directs cooler air to the upper outlets and warmer air to
the floor outlets.
H
(Vent): This mode directs air to the instrument
panel outlets.
?
RECIRC (Recirculation): This mode keeps
outside air from coming in the vehicle. It can be used to
prevent outside air and odors from entering your
vehicle or to help heat or cool the air inside your vehicle
more quickly. Press this button to turn the recirculation
mode on or off. When the button is pressed, an indicator
light will come on. The recirculation mode cannot be
used with the FRONT defrost mode.
3-26
#
A/C (Air Conditioning): Press this button to turn
the air conditioning compressor on and off. When A/C is
pressed, an indicator light in the button will come on
to let you know that air conditioning is activated. If your
climate control system is off, you may also turn it
back on in vent mode by selecting the A/C button.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce the
time it takes for your 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 the vent mode.
2. Select the recirculation mode.
3. Select A/C.
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
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
