Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would
not be covered by your warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.
Dual Climate Control System
Your vehicle may have a dual climate control system.
With this system you can control the heating, cooling,
and ventilation for your vehicle.
Operation
Turn the right knob clockwise or counterclockwise to
direct the airow inside your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
3-30

)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, then directs the remaining
air to the oor outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets. Use this mode to send air to the rear of
the vehicle. Keep the area under the front seats free
of objects that could obstruct airow to the rear of
the vehicle.
The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging
and Defrosting” later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the knob counterclockwise until it stops to turn
off the fan. The fan must be turned on for the air
conditioning compressor to operate.
@(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 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 air-conditioning compressor also comes
on. The recirculation mode can be used with vent
and bi-level modes, but it cannot be used with oor,
defog, defrost or outside air modes.Temperature Control:Use the driver’s and passenger’s
temperature levers to increase or decrease the air
temperature inside your vehicle.
uA/C (Air Conditioning):Press this button to turn
the air-conditioning system on or off. When A/C is
pressed, an indicator light in the button will come on to
let you know that air conditioning is activated.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
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.
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.

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity,
or moisture, condensing on the cool window glass.
This can be minimized if the climate controls system is
used properly. There are two modes to clear fog or
frost 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.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs air to the windshield
and the oor outlets. When you select this mode,
the system turns off recirculation and runs the
air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the defog mode.
0(Defrost):This mode directs most of the air to
the windshield and the side window outlets, with some
air directed to the oor outlets. 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. Recirculation
cannot be selected while in the defrost mode.
Do not drive the vehicle until all the windows are clear.

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 your 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’re 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’s a problem with your vehicle.
When one of the warning lights comes on and stays
on when 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. Please follow
this manual’s advice. Waiting to do repairs can be
costly – and even dangerous. So please get to know
your warning lights and gages. They’re a big help.
Your vehicle also has a message center that
works along with the warning lights and gages.
SeeMessage Center on page 3-51.

Retro-Active Reset
The trip odometer has a feature called retro-active
reset. This feature can be used to set the trip odometer
to the number of miles or kilometers driven since the
ignition was last turned on. This can be used if you
forget to reset your trip odometer at the beginning of a
trip. To use the retro-active reset feature, push and
hold the trip/reset button for at least ve seconds. The
trip odometer will then display the number of miles
or kilometers driven since the ignition was last turned
on and you began driving. If you use the retro-active
reset feature after you have started the vehicle,
but before you begin moving, the display will show
the number of miles or kilometers you drove during
the last ignition cycle. Once you begin driving, the
trip odometer will accumulate mileage. For example,
if you have driven 5.0 miles (8.0 km) since you started
your vehicle, and then activate the retro-active reset
feature, the display will show 5.0 miles (8.0 km).
As you drive, the display will then increase to
5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
Tachometer
The tachometer
displays the engine
speed in revolutions
per minute (rpm).
Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for several seconds to remind people to fasten
their safety belts.
The safety belt light will
also come on and stay on
for several seconds. If
the driver’s belt is already
buckled, neither the
chime nor the light will
come on.

Anti-Lock Brake System
Warning Light
Your vehicle may have an anti-lock brake system
warning light. If it does, the light should come on for a
few seconds when you turn the ignition key to ON. If the
anti-lock brake system warning light stays on longer
than normal after you’ve started your engine, turn
the ignition off. If the light comes on and stays on when
you are driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you are driving, the anti-lock brake system needs
service and you do not have anti-lock brakes.
The anti-lock brake system warning light should come
on briey when you turn the ignition key to ON.
If the light does not come on then, have it xed so it
will be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
Your vehicle may have a traction control system
warning light. The traction control system warning light
may come on for the following reasons:
If you turn the system off by pressing the TRAC OFF
button located in the instrument panel switchbank the
warning light will come on and stay on. To turn the
system back on, press the button again. The warning
light should go off. SeeTraction Control System
(TCS) on page 4-10for more information.
If there’s an engine-related and brake system
problem that is specically related to traction control,
the traction control system will turn off and the
warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service. United States

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves near the “H”, your engine
is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-23.

3-46

This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON or check
engine light comes on to indicate that there is a problem
and service is required. Malfunctions often will be
indicated by the system before any problem is apparent.
This may prevent more serious damage to your
vehicle. This system is also designed to assist your
service technician in correctly diagnosing any
malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls may not
work as well, your fuel economy may not be as good,
and your engine may not run as smoothly. This could
lead to costly repairs that may not be covered by
your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 5-3.
This light should come on, as a check to show you
it is working, when the ignition is on and the engine
is not running. If the light does not come on, have
it repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system
on your vehicle. Diagnosis and service may
be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
