If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose generator drive
belt or another electrical problem. Have it checked
right away. 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.
This light should come on briefly when you turn the
ignition key to
RUN. 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 “Towing Your Vehicle”
in the Index.)
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.

Engine Coolant Temperature Gage
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.
In “Problems
on the Road,’’ this manual shows what to

United States
CHECK
Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called
OBD I1 (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.
I 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.

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. Retailer
or qualified service center
diagnosis and service may
be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Retailer 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.
0 Avoiding hard accelerations.
Avoiding steep uphill grades.
0 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
“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 drive the vehicle to your
retailer 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. 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.

GAGES
This light will come on
briefly when you are
starting the engine.
If it stays on, or if it comes on and stays on while you
are driving, check your various gages to see if they
are in the warning zones.
Fuel Gage
W
UNLEADED FUEL ONLY
Your fuel gage tells you
about how much fuel you
have left, when the ignition
is on. When the indicator
nears EMPTY
(E), you still
have a little fuel left, but
you should get more
soon.
Here are four things that some owners ask about. None
of these show a problem with your fuel gage:
0
0
0
0
At the service station, the gas pump shuts off before
the gage reads
FULL (F).
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but
it actually took a
little more or less than half the tank’s capacity to fill
the tank.
The gage moves a little when you turn a corner
or
speed up.
The gage doesn’t go back
to EMPTY (E) when you
turn
off the ignition.
