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 doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady,
see ªIf the Light Is On Steadyº following.If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

2-95
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts
of air are sucked into the fuel line causing a misfire.
The system can detect this. Adding fuel should correct
this condition. Make sure to install the fuel cap properly.
See ªFilling Your Tankº in the Index. It will take a few
driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
ªFuelº in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start
-up, stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling on acceleration. (These conditions may go
away once the engine is warmed up.) This will be
detected by the system and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON or CHECK ENGINE light
is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.

2-97
Charging System Indicator Message
The charging system battery
symbol will come on in
the message center when
you turn on the ignition as
a check to show you it
is working.
It will remain on as long as the engine is not running.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system. It could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
Driving while this indicator appears in the message
center could drain your battery.
If you must drive a short distance with the message on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
Service Traction System Warning
Message (Option)
If your vehicle has the
traction control system and
this message is displayed
when you're driving, there
may be a problem with your
traction control system.
Your vehicle may need service.
When this message is displayed, the traction control
system will not limit wheel spin. Adjust your
driving accordingly.
The message may appear for the following reasons:

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning message will come on.
If your brakes begin to overheat, the traction control
system will turn off and the warning message will
come on until your brakes cool down.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning message will come on.
If the traction control system warning message comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

Comfort Controls
This section tells you how to make your air system work
for you.
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has a
flow
-through ventilation system described later in
this section.
Fan Knob
The left knob is the fan knob and selects the force of air
you want. Turn the knob clockwise to increase fan speed
and counterclockwise to decrease fan speed. The fan
must be turned on for the air conditioning compressor
to operate.Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it clockwise (toward
the red area) for warmer air. Turn it counterclockwise
(toward the blue area) for cooler air.
Mode Knob
The right knob is used to select and determine the
direction of the air flowing into the vehicle.
UPPER: This setting directs outside air through
the instrument panel outlets.
BI-LEVEL: This setting directs outside air into
your vehicle in two ways. Cooler air is directed toward
your upper body through the front instrument panel
outlets, while warmed air is directed through the heater
ducts at your feet.
LOWER: This setting brings in most of the air
through the floor ducts. This setting is also used to send
air to the rear of the vehicle. Keep the area under the
front seats free of objects that could obstruct airflow to
the rear of the vehicle.

3-3
DEFOG: This setting directs air to the
windshield and through the floor ducts. This mode is
useful during cold or inclement weather because of your
vehicle's larger windshield area.
DEFROST: This setting directs most of the air to
the windshield and side window vents.
Mode Buttons
OUTSIDE AIR: Press this button
(the light will glow) to send outside air into your
vehicle. Using this setting while trying to defrost or
defog the windows will help clear the vents of moisture.
Press the RECIRCULATION button (the light on the
OUTSIDE AIR button will go off) to limit outside air
entering the vehicle. When the DEFOG or DEFROST
setting is selected, the system will automatically go to
OUTSIDE AIR mode.
RECIRCULATION: Press this button
(the light will glow) to limit the amount of fresh air
entering your vehicle by recirculating much of the air
inside your vehicle. You may use this setting to limit
odors entering your vehicle. Press the OUTSIDE AIR
button (the light on the RECIRCULATION button will
go off) to let outside air circulate into the vehicle.Operating the Heating/Ventilation/Air Conditioning
(HVAC) system in the RECIRCULATION mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
HVAC system to either the DEFOG or DEFROST mode
and increase the fan speed. To avoid re
-fogging of
the windows, operate the HVAC system in the
OUTSIDE AIR mode.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot, inside air escape. For all settings,
adjust the temperature control knob and fan speed
as desired.
To get maximum cooling or a quick cool
-down on very
hot days, press the A/C and RECIRCULATION buttons
(the lights will glow) and turn the temperature knob
counterclockwise (toward the blue area). Adjust the
mode knob to direct the air to the desired location.
This setting should not be used for long periods of time
because the air may become too cold and dry. Push the
A/C button again (the light will go off) to turn off the
air conditioning.

3-4
When the air conditioner compressor is on, you may
sometimes notice slight changes in your vehicle's engine
performance and power. This is normal. The system is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air, so
you may sometimes notice water dripping from under
your vehicle's engine compartment when it is idling or
after it has been turned off. This is normal.
Heating
Turn the temperature knob clockwise (toward the red
area) to warm the air.
In the LOWER setting, outside air will be brought in
and sent through the floor outlets. The heater works best
if you keep your windows closed while using it.
The BI
-LEVEL setting is designed for use on sunny
days when the air is only moderately warm or cool.
On days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. For the best results, turn the temperature
control knob to the middle position, and then adjust it
for comfort.If you have the optional engine coolant heater and use it
during cold weather, 0
F (
-18
C) or lower, your heating
system will provide heat more quickly because the
engine coolant is already warmed. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
To rapidly defrost the windshield, turn the temperature
control knob all the way clockwise (to the red area) and
turn the mode knob to DEFROST. Adjust the fan to the
highest speed.
To keep the windshield clear and bring in heated air
through the heater ducts, turn the mode knob
to DEFOG.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
to the BI
-LEVEL setting and adjust the fan to the
highest speed. Aim the side vents on the instrument
panel toward the side windows. For increased airflow to
the side vents, close the center vents.
