2-57 Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on
for three seconds.
That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on and the chime sounds when you're
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're
driving, your vehicle needs service. If the regular brake
system warning light isn't on, you still have brakes, but
you don't have anti
-lock brakes. If the regular brake
system warning light is also on, you don't have anti
-lock
brakes and there's a problem with your regular brakes.
See ªBrake System Warning Lightº earlier in
this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, the light comes on
and you hear a chime, 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.
See ªEngine Overheatingº in the Index.

2-58 Low Coolant Warning Light
This light comes on
briefly when you turn
your ignition on.
If this light comes on and stays on, the vehicle should
promptly be pulled off the road and the coolant level
checked. The coolant level could be too low.
See ªEngine Coolantº in the Index. If there are visible
signs of steam, see ªEngine Overheatingº in the Index
before opening the hood. Have your vehicle serviced as
soon as you can.
Malfunction Indicator Lamp
(Check Engine Light)
United States Canada
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 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.

2-59
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 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:
Modifications 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 the CHECK ENGINE light to
come on. Modifications 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 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.

2-60
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.

2-61
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 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.

2-62 Oil Pressure Light
If you have a low engine oil
pressure problem, this light
will stay on after you start
your engine, or come on
and you will hear a chime
when you are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have some
other oil problem. Have it fixed immediately.
When the ignition is on but the engine is not running,
the light will come on as a test to show you it is
working, but the light will go out when the engine is
running. If it doesn't come on with the ignition on,
you may have a problem with the bulb. Have it fixed
right away.CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

2-63 Check Oil Light
You will have a CHECK
OIL light in your instrument
panel cluster.
This light will come on briefly when you start
your vehicle.
If the light stays on after starting your vehicle, or comes
on and chimes while you are driving, your engine oil
level should be checked.
Prior to checking the oil level, be sure your vehicle
has been shut off for several minutes and is on a level
surface. Check the oil level on your dipstick and bring
it to the proper level. See ªEngine Oilº in the Index.
A false CHECK OIL light may be generated when
parking on steep grades.The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for a
considerable period of time allowing the oil normally
in circulation to drain back into the oil pan.
Passlock
Warning Light
This light will come on
when you turn the ignition
to ON. The light will stay
on until the engine starts.
If the light flashes, the Passlock system has entered a
tamper mode. If the vehicle fails to start, see ªPasslockº
in the Index.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
system. Your vehicle will not be protected by Passlock,
and you should see your dealer.

2-65 Service Vehicle Soon Light
This light will come on
briefly when you turn
on the ignition.
It will stay on or come on and chime if it detects a
problem on the vehicle, such as a Daytime Running
Lamp (DRL) or an Automatic Light Control (ALC)
malfunction. If this happens, see your dealer service
department as soon as possible.
Door Ajar Light
When the ignition is on,
this light will stay on until
all doors are closed and
completely latched.
You will hear a chime if a door is unlatched after the
engine is started and the vehicle is not in PARK (P)
or NEUTRAL (N).

3-4 Air Conditioning
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow
-through ventilation system described
later in this section.
For normal cooling on hot days, after the vehicle has
started to cool down, use UPPER with the temperature
knob in the blue area and the A/C button pushed in.
The system will bring in outside air and cool it.
On very hot days, open the windows long enough to
let hot inside air escape. This reduces the time it takes
for your vehicle to cool down, which should help
fuel economy.
For quicker cool
-down on very hot days, use UPPER
with the temperature knob all the way in the blue area
and the A/C and RECIRCULATION buttons pressed.
If this setting is used for long periods of time, the air in
your vehicle may become too dry.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI
-LEVEL with the temperature knob in
the middle and the A/C button pushed in. The system
will bring in outside air and direct slightly warmer air to
your lower body.
Heating
On cold days, use FLOOR and the OUTSIDE AIR
button with the temperature knob all the way in the red
area. The system will bring in outside air, heat it and
send it to the floor outlets.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system uses to provide heat. See ªEngine Coolant
Heaterº in the Index.

3-7
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction, such as leaves. The heater and
defroster will work far better, reducing the chance of
fogging the inside of your windows.

When you enter a vehicle in cold weather, adjust the
mode knob to FLOOR and the fan to the highest speed
for a few moments before driving off. This helps clear
the intake ducts of snow and moisture and reduces the
chance of fogging the inside of your windows.

Keep the air path under the front seats clear of objects.
This helps air circulate throughout your vehicle.

To prevent circulation of outside air, press the
RECIRCULATION button. This will close all
outside outlets.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is off. See ªRetained
Accessory Powerº in the Index.
Setting the Clock for Systems without Radio
Data System (RDS)
Press and hold the HR or MIN arrow for two seconds.
Then press the HR arrow until the correct hour appears.
Press and hold the MIN arrow until the correct minute
appears. The clock may be set with the ignition on
or off.
