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

inside your vehicle, they use the information to maintain
the selected temperature by adjusting to the
temperature, the fan speed, and the air delivery system.
The system may also supply cooler air to the side of
the vehicle facing the sun. The recirculation mode
will also be activated, as necessary. Do not cover the
sensors or the automatic climate control system will not
work properly.

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.
SeeOutlet Adjustment on page 3-28for more
information.
0(Defrost):Pressing defrost directs most of the air
to the windshield, with some air directed to the side
windows. In this mode, the system will automatically turn
off recirculation and run the air-conditioning compressor,
unless the outside temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
If there is fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-28
for more information. Do not drive the vehicle until all the
windows are clear.
Rear Window Defogger

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
Compartment Overview on page 5-12for more
information on location.Use the procedure listed below to replace the passenger
compartment air lter:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them off
again when the wipers are straight on the
windshield.
This allows you access to the leaf screen. The
passenger compartment air lter is located under
the leaf screen.
3. Open the hood to access the engine compartment.
SeeHood Release on page 5-11for more
information.
4. Remove the four screws that hold the leaf screen in
place and lift off the screen by lifting and sliding
toward the center of the vehicle.
5. Pull out on the two tabs located on each end of the
lter cover.
6. Lift the lter cover off by pulling it straight upward.
7. Remove the old lter and insert a new one.
Make sure the arrow on the lter is pointing toward
the passenger compartment.

(CTS) on page 3-7for more information on programming
these controls.
Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages that may
be on your vehicle. The pictures will help you locate them.Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some warning
lights come on briey when you start the engine just to let
you know they are working. If you are familiar with this
section, you should not be alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
while you are driving, or when one of the gages shows
there may be a problem, check the section that tells
you what to do about it. Waiting to do repairs can be
costly – and even dangerous. So please get to know your
warning lights and gages. They are a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-53for
more information.
