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 control 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.
For best results, clear all snow and ice from the
windshield before defrosting.
Select one of these available modes from the right knob.
É(Defog):This mode directs most of the air to the
windshield and the floor outlets. A small amount of air is
also directed to the outboard outlets for the side windows
and to the instrument panel side outlets. When this
mode is selected, the system runs the air-conditioning
compressor. To defog the windows faster, turn the
temperature control knob clockwise to the warmest
setting.
1(Defrost):This mode directs the air to the
windshield and the outboard outlets for the side windows.
A small amount of air is also directed to the instrument
panel side outlets. When this mode is selected, the
system runs the air-conditioning compressor. To defrost
the windows faster, turn the temperature control knob
clockwise to the warmest setting.
Do not drive the vehicle until all windows are clear.
Rear Window and Outside Mirror
Defogger
Your vehicle may have a rear window and outside
mirror defogger. This feature only works when
the ignition is turned to ON/RUN.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Before
using this feature, clear as much snow from the
rear window as possible.
<(Rear Window Defogger):Press this button to
turn the rear window and outside mirror defogger on
or off. An indicator light in the button comes to show
that the feature is activated.
If your vehicle does not have air conditioning, the rear
window defogger will remain on until the button is
pressed again or the engine is turned off.
If your vehicle has air conditioning, the rear window
defogger will turn off about 10 minutes after the button
is pressed. The defogger can also be turned off by
pressing the button again or by turning the engine off.
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.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle.
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 the
details show on the next few pages, some warning lights
come on briefly 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
as 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 vehicle’s
warning lights and gages. They can be a big help.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles (used in the United States)
or kilometers (used in Canada).
Trip Odometer
The trip odometer can record the number of miles, used
in the United States, or kilometers, used in Canada,
traveled for up to two trips.
You can cycle between the odometer and trip
odometers A and B by pressing the reset button
located in the lower right area of the speedometer.
By pressing the reset button, you can tell how many miles
or kilometers have been recorded on either Trip A or
Trip B since you last set the trip odometer back to zero.
To reset each trip odometer to zero, press and hold
the reset button. The reset button resets only the
trip odometer that is being displayed. Each trip
odometer must be reset individually.
Tachometer
The tachometer displays your engine speed in
revolutions per minute (rpm).
Notice:If you operate the engine above 6,500 rpm,
your vehicle could be damaged, and the damages
would not be covered by your warranty. Do not
operate the engine with the tachometer above
6,500 rpm.Hatchback

Safety Belt Reminders
Safety Belt Reminder Light
The safety belt light will
come on when the engine
is started and stay on
until the driver’s safety belt
is buckled.
If the driver’s belt is already buckled, the light will not
come on.
Safety Belt Reminder Tone
If your vehicle has this feature, a tone will sound for
several seconds when the engine is started to remind
people to fasten their safety belts. The tone will not
sound if the driver’s safety belt is already buckled.
Airbag Readiness Light
There is an airbag readiness light on the instrument panel
cluster, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system check includes the airbag sensor, the airbag
modules, the wiring and the crash sensing and diagnostic
module. For more information on the airbag system,
seeAirbag System on page 1-56.
This light will come on
when you start your

system is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your airbag
system may not work properly. Have your vehicle
serviced right away.
3-30

{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags 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 airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should flash for a few
seconds when the engine is started. If the light does not

Charging System Light
This light will come on
briefly when the ignition
is turned on, and the
engine is not running,
as a check to show
you it is working.
It should go out when the engine is started. If it stays
on, or comes on while you are driving, you may have
a problem with the electrical charging system. Have
it checked by your dealer/retailer. Driving while this
light is on could drain your battery. If you must drive
a short distance with the light on, be certain to turn
off all your accessories, such as the radio and air
conditioner to help reduce the drain on the battery.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does not fully
release. If it stays on after your parking brake is fully
released, it means you have a brake problem.

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal
is harder to push or the pedal may go closer to the
floor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-27.
{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.
Antilock Brake System Warning
Light
For vehicles with
the Antilock Brake
System (ABS), this light
will come on briefly
when the engine is started.
If the light stays on, turn the ignition to LOCK/OFF or if
the light comes on, 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, your vehicle needs service. See your
dealer/retailer. If the regular brake system warning light is
not on, you still have brakes, but you do not have antilock
brakes. If the regular brake system warning light is also
on, you do not have antilock brakes and there is a
problem with your regular brakes. SeeBrake System
Warning Light on page 3-33.
The ABS warning light will come on briefly when you
turn the ignition to ON/RUN. This is normal. If the
light does not come on then, have it fixed so it will
be ready to warn you if there is a problem.

Hold Mode Light
If your vehicle has this
feature, this light comes
on when the hold mode
is active.
If the HOLD mode light flashes, have your vehicle
checked. See “Hold Mode” underAutomatic
Transmission Operation on page 2-21for more
information.
Engine Coolant Temperature Gage
Your vehicle has an engine coolant temperature gage.
With the ignition turned to ON/RUN, this gage shows
the engine coolant temperature.
If the gage pointer moves into the red area, 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 5-25.

Tire Pressure Light
Your vehicle has a tire
pressure light.
This light comes on briefly when the engine is started
and provides information about tire pressures and
the Tire Pressure Monitoring System.
When the Light is Solid
This indicates that one or more of your tires are
significantly underinflated.
Stop and check your tires as soon as it is safe to do so.
If underinflated, inflate to the proper pressure.
SeeTires on page 5-50for more information.
When the Light Flashes First and Then is
Solid
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light will flash for about a
minute and then stay on solid for the remainder of the
ignition cycle. This sequence will repeat with every
ignition cycle. SeeTire Pressure Monitor System on
page 5-58for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the life of
the vehicle, helping to produce a cleaner environment.
The check engine light
comes on to indicate
that there is an OBD II
problem and service
is required.
Malfunctions often are indicated by the system before
any problem is apparent. This can 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, the emission controls might
not work as well, your vehicle’s fuel economy might
not be as good, and the engine might not run as
smoothly. This could lead to costly repairs that
might not be covered by your warranty.
3-36

Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of your
vehicle or replacement tires that do not match your
vehicle’s original tires can affect your vehicle’s
emission controls and can cause this light to come
on. Modications to these systems could lead to
costly repairs not covered by your warranty. This
could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 5-3.
When the ignition is turned to ON/RUN, this light comes
on and should go out after a few seconds as a check
to show it is working. If the light does not come on, have
it repaired. This light also comes on during a malfunction
in one of two ways:
•Light Flashing— A misfire condition has been
detected. A misfire increases vehicle emissions
and could damage the emission control system
on your vehicle. Diagnosis and service might
be required.
•Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service might be required.
If the Light Is Flashing
The following can prevent more serious damage to your
vehicle:
•Reduce vehicle speed.
•Avoid hard accelerations.
•Avoid steep uphill grades.
If the light stops flashing and remains on steady,
see “If the Light Is On Steady” 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 “If the Light Is
On Steady” following. If the light is still flashing, follow the
previous steps, and see your dealer/retailer for service as
soon as possible.
