Brake System Warning Light
This light should come on briey when you turn the
ignition to RUN. If it does not come on then, have it xed
so it will be ready to warn you if there is a problem.
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 brake system warning light comes on, there is a
brake problem. Have your brake system inspected
right away.
When the ignition is on, the BRAKE light will come on
when you set your parking brake. The light will stay on if
your parking brake does not release fully. A chime will
also sound if the parking brake is not fully released and
the vehicle is moving. If it stays on after your parking
brake is fully released, it means you have a brake
problem.The BRAKE light will also come on to indicate a low brake
uid level. SeeBrakes on page 5-39for more information.
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 oor.
It may take longer to stop. Make sure the parking brake
is fully released. Turn the ignition off and wait several
seconds to restart vehicle, if the light is still on, have the
vehicle towed for service. SeeTowing Your Vehicle on
page 4-36.
{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,

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 4-36.
The anti-lock brake system warning light should come on
briey when you turn the ignition key to RUN. If the light
does not come on then, have it xed so it will be ready to

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°F
(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 3-43.
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
Check Engine Light
Your vehicle has 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.

ProCarManuals.com

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.
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 the Tank on page 5-7. 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.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. 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, misring, 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,
your retailer can check the vehicle. Your retailer has the
proper test equipment and diagnostic tools to x 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, your
retailer can prepare the vehicle for inspection.

Boost Gage
If your vehicle is equipped with this gage, it is located
on the steering column.
This gage indicates vacuum during light to moderate
throttle and boost under heavier throttle.
This gage displays the air pressure level in the intake
manifold before it enters the engine’s combustion
chamber.
This gage is automatically centered at zero every time
the ignition is turned to RUN. Actual vacuum or boost
is displayed from this zero point.The boost gage is also equipped with three pairs of
lights that are located on each side of the gage. These
lights are used to indicate three different engine rpm
levels. The default setting for the lower pair of lights is
4,400 rpm, the middle pair of lights is 5,600 rpm, and the
top pair of lights is 6,200 rpm. These settings can be
adjusted by turning the stem behind each light. To have
the light pair come on at a higher rpm level, turn the stem
