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 or frost
from your windshield and side windows. 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.
For best results, clear all snow and ice from the
windshield before defrosting.
Turn the left knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets and half to the
oor outlets.To defog the windows faster, turn the
temperature control knob clockwise to the warmest
setting.
0(Defrost):This mode directs most of the air to the
windshield, with some air directed to the side window
outlets and the oor outlets.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
<(Rear):Press the button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible. An indicator light above
the button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will turn off approximately
15 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately ve
minutes before turning off. The defogger can also
be turned off by pressing the button again or by turning
off the engine.
Notice:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar
to the defogger grid.

The air-conditioning compressor also comes on.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode.
#(Air Conditioning):Press this button to turn the
air-conditioning system on or off. When this button
is pressed, an indicator light above the button will come
on to let you know the air conditioning is activated.
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:
1. Select the recirculation mode.
2. Select air conditioning.
3. Select the coolest temperature.
4. 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 off the recirculation by
pressing the button again.
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.

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 3-41.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer is located in your message center,
and shows how far your vehicle has been driven, in
either miles (used in the United States) or kilometers
(used in Canada).
When information messages need to be shown in the
message center, they will be shown in place of the
odometer. To display the odometer after a message(s) is
shown, clear each message by pressing the trip/reset
button located to the right of the speedometer. See
Message Center on page 3-41for more information.
Your vehicle has a tamper-resistant odometer. You may
wonder what happens if your vehicle needs a new
odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
If it can’t, it will be set at zero and a label must be put
on the driver’s door to show the old mileage reading
when the new odometer was installed. If the mileage is
unknown, the label should then indicate “previous
mileage unknown”.
Trip Odometer
Your trip odometer shows how far your vehicle has
been driven since the trip odometer was last reset.
To reset the trip odometer to zero, press and hold the
trip/reset button for about two seconds.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not be
covered by your warranty. Do not operate the engine
with the tachometer in the shaded warning area.
The maximum rpm is limited in PARK (P) and
NEUTRAL (N) to 4000 rpm by the vehicle’s computer.
This is to prevent engine damage.

{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should ash for a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it xed so it will
be ready to warn you if there is a problem.
Battery Warning Light
The battery warning light
will come on briey as a
check, when you turn
on the ignition. Then it
should go out when
the engine is started.
If the light does not come on when you start your
vehicle, have your vehicle serviced right away. This
condition may indicate your battery warning light is not
functioning properly. If this light comes on while you
are driving, be sure to turn off accessories such as the
radio and climate control system. Have your vehicle
serviced right away.

Anti-Lock Brake System
Warning Light
If your vehicle has anti-lock brakes, the anti-lock brake
system (ABS) warning light will come on briey, as
a check, when you start your vehicle. If it doesn’t, have
your vehicle serviced so that the light works properly
when it needs to.
The ABS light is located in
the instrument panel
cluster, to the left of the
engine coolant temperature
gage.
If the light stays on longer than a few seconds after
you start your engine, or comes on and stays on
while you are driving, try resetting the system.To reset the system, do the following:
1. If you are driving, pull over when it is safe to do so.
2. Be sure the vehicle is in PARK (P).
3. Turn off the ignition.
4. Then restart the engine.
If the light remains on after resetting the system or
comes on again while driving, your vehicle needs
service. If the ABS light is on, but the regular brake
system warning light is not on, you do not have anti-lock
brakes, but you still have regular brakes. Have your
vehicle serviced right away. If both brake lights are on,
you do not have anti-lock brakes, and there’s a
problem with your regular brakes as well. Have your
vehicle towed for service. SeeTowing Your Vehicle on
page 4-31.

Engine Coolant Temperature Gage
This gage on the left
measures the temperature
of the vehicle’s engine
coolant. If the pointer
moves into the shaded
area, your engine is
too hot!
If the engine coolant temperature reaches 253° (123°C)
the CHK GAGE message will appear and a chime
will sound to alert you to the engine coolant
temperature gage. SeeMessage Center on page 3-41.If you have been operating your vehicle under normal
driving conditions, you should pull off the road and
stop your vehicle, be sure the air conditioning is off,
let the engine idle for a few minutes, then turn off
the engine.
If your engine control system detects a failure in the
engine coolant temperature circuit, the malfunction
indicator lamp (service engine soon) light will come on.
The coolant gage may read all the way hot or cold.
The engine cooling fan will be turned on to protect the
engine and transmission. SeeMalfunction Indicator
Lamp on page 3-36for more information.

Malfunction Indicator Lamp
Service Engine Soon Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
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 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 a while, your emission controls
may not work as well, your fuel economy may notbe 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.
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.

ProCarManuals.com

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 ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, 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 “If the
Light Is On Steady” following. If the light is still ashing,
follow the previous steps, and see your retailer for
service as soon as possible.
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. SeeFilling Your Tank on page 5-8.
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.
