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. Dealer or qualified service center diagnosis
and service
is required.
0 Light On Steady -- An emission control system
malfunction has been detected
on your vehicle.
Dealer or qualified service center diagnosis and
service rnay be required. The
following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 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
"If
the Light Is On Steady" following.
If the light continues to flash, when it is safe to do so,
stop the velzicle. 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 "lf the Light
Is On Steady" following. If the light is still flashing.
follow the previous steps, and drive the vehicle
to your
dealer or qualified service center for service.
You may
be able to correct the emission system
malfunction by considering the following:
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.

Downloaded from www.Manualslib.com manuals search engine 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. 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
“Fuel”
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. This light
tells you if there
could be a problem with
your engine oil pressure.
The light
goes on when you turn your key to RUN or
START. It goes off once you start your engine. That‘s a
check
to be sure the light works. If it doesn’t come on,
be sure to have
it fixed so it will be there to warn you
if something goes wrong.
When
the light comes on and stays on, it means that
oil isn’t flowing through your engine properly.
You
could be low on oil and you might have some other
system problem.

A 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 oii 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
