2-39 Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't 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.
United States Canada
This light should come on when you turn the key to
START. If it doesn't come on then, have it fixed so it
will be ready to warn you if there's a 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. (See ªAnti
-Lock Brake
System Warning Lightº and ªTowing Your Vehicleº in
the Index.)
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've
pulled off the road and stopped carefully, have
the vehicle towed for service.
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 doesn't release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.

2-40 Anti-Lock Brake System Warning Light
(Option)
With the anti-lock brake
system, this light will come
on when you start your
engine and it will stay on
for three seconds.
That's normal.
If the light comes on when you're driving, you don't
have anti
-lock brakes and there could be a problem with
your regular brakes. 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. Have the vehicle towed for service. (See ªTowing
Your Vehicleº in the Index.)
CAUTION:
Your regular brake system may not be working
properly if the anti
-lock brake system warning
light is on. Driving with the anti
-lock brake
system warning light on can lead to an accident.
After you've pulled off the road and stopped
carefully, have the vehicle towed for service.
If the anti-lock brake system warning light stays on
longer than normal after you've started your engine, turn
the ignition off. Or, if the light comes on and stays on
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
light is on and the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti
-lock brakes.
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.

yellowblue
2-41 Anti-Lock Brake System Active Light
(Option)
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the anti
-lock brake system
active light will come on.
Slippery road conditions may exist if this light comes
on, so adjust your driving accordingly. The light will
stay on for a few seconds after the system stops
adjusting brake pressure.
The anti
-lock brake system active light also comes 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 there to
tell you when the system is active.
Engine Coolant Temperature Gage
Standard Cluster Optional Cluster
This gage shows the engine coolant temperature. If the
gage pointer moves to the HOT (H) side of the band,
your engine is too hot! It means that your engine coolant
has overheated and you should stop your vehicle and
turn off the engine as soon as possible.
In ªProblems on the Road,º this manual shows what to
do. See ªEngine Overheatingº in the Index.

2-42 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 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 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 SERVICE ENGINE SOON
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.

2-43
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?

yellowblue
2-44
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.
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.
Oil Pressure Light
If you have a problem with
your oil pressure this light
may stay on after you start
your engine, or come on
when you are driving.
This indicates that there is not enough pressure to keep
your engine properly lubricated and cool. The engine
could be low on oil, or have some other oil problem.
Have it fixed right away.

yellowblue
2-45
The oil light could also come on in three other situations:

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. If it doesn't come on with the ignition on,
you may have a problem with the fuse or bulb. Have
it fixed right away.

Sometimes when the engine is idling at a stop, the
light may blink on and off. This is normal.

If you make a hard stop, the light may come on for a
moment. This is normal.
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.
Daytime Running Lamps (DRL)
Indicator Light
You will have this light on
the instrument panel. It goes
on whenever the daytime
running lamps are on.

yellowblue
2-46 Fuel Gage
Standard Cluster Optional Cluster
Your fuel gage shows about how much fuel is in your
tank. When the gage first indicates E (empty), you still
have a little fuel left (about 1 or 2 gallons (3.8 or 7.6L),
but you need to get more right away.Here are four concerns some owners have had about the
fuel gage. All of these situations are normal and do not
indicate that anything is wrong with the fuel gage.

At the gas station, the gas pump shuts off before the
gage reads F (full).

It takes more (or less) gas to fill up than the gage
reads. For example the gage reads half full, but it
took more (or less) than half of the tank's capacity to
fill it.

The gage moves a little when you turn, stop or
speed up.

When you turn the engine off, the gage doesn't go
back to E (empty).
