To change the current mode, select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets. In
automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets (for the side windows), and a little air directed to
the windshield.
The mode switch can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
yAz(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-29
andScheduled Maintenance on page 6-4.
h(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. The air-conditioning compressor also comes

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog from
your windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from
the windshield more quickly.
yNz(Mode):Press this button until defog appears
on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows. When this
mode is selected, the system turns off recirculation and
runs the air-conditioning compressor unless the outside
temperature is at or below freezing. If recirculation mode
is selected while in defog mode, it will be cancelled after
10 minutes.
If there is fog on the side windows, turn the thumbwheel
on the outboard outlets to the side window defog position.

Passenger Compartment Air Filter
The passenger compartment air lter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/lter, it needs to be changed
periodically. SeeScheduled Maintenance on page 6-4.
Using the climate control system without the passenger
air lter installed may allow water or other debris to
enter the system. This could cause a water leak
or noises. Make sure to install a new air lter after
removing the old one.
The passenger compartment air lter is located
underneath the hood below the windshield wiper arm on
the passenger’s side of the vehicle. SeeEngine
