Anti-Lock Brake System
Warning Light
Your vehicle may have
this light. If it does, the
anti-lock brake system
warning light should come
on for
a few seconds
when you turn the ignition
key to RUN.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn

Malfunction Indicator Lamp
Service Engine Soon Light in the
United States or Check Engine Light
in Canada
SERVICE
ENGINE
SOON
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 accepiabie ieveis ior ine iiie
of ihe
vehicle, helping to produce a cleaner environment.
3-47

The SERVICE ENGINE SOON or 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.
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 this 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.
3-48

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
“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 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
Filling Your 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.
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
misfire. The system can detect this. Adding fuel should
correct this condition. Make sure to install the fuel
cap properly. See
Filling Your Tank on page 5-7.
It will take a few driving trips to turn the light off.
3-49

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, 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 to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection
if the SERVICE
ENGINE SOON or
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.
