Your vehicle is equipped with a crash sensing and
diagnostic module, which records information
about the air bag system. The module records
information about the readiness of the system, when
the system commands air bag inflation and
driver’s safety belt usage at deployment.
Let only qualified technicians work on your air bag
system. Improper service can mean that your air
bag system won’t work properly. See your dealer for
service.
Notice: If you damage the covering for the driver’s
or the right front passenger’s air bag, the bag
may not work properly. You may have to replace the
air bag module in
the steering wheel or both the
air bag module and the instrument panel for
the right front passenger’s air bag. Do not open or
break
the air bag coverings.
Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don’t want the system to
inflate white someone is working on your vehicle. Your dealer and
the service manual have information
about servicing your vehicle and the air bag system.
To purchase a service manual, see Service Publications
Ordering Information on page
7-9.
For up to 10 minutes after the ignition key is
turned
off and the battery is disconnected, an
air bag can
still inflate during improper
service. You can be injured
if you are close to
an air bag when
it inflates. Avoid wires
wrapped with yellow tape or yellow connectors. They are probably part of the air bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualified to do
so.
The air bag system does not need regular maintenance.

Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces.
If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Replacing Restraint System Parts
After a Crash
A crash can damage the restraint systems in
your vehicle.
A damaged restraint system may
not properly protect the person using
it,
resulting in serious injury or even death in a
crash.
To help make sure your restraint
systems are working properly after
a crash,
have them inspected and any necessary
replacements made as soon as possible.

Malfunction Indicator Lamp
Service Engine Soon Light
SERVICE
ENGINE
SOON
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
smoothly. This could lead to costly repairs that may not be covered by your warramty.
be 85 gcod and yaur engine may not run as
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 &y 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:
e
e
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.
3-31

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

When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 start your engine,
0 shift into a gear, and
0 release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill), engine
oil, drive belt, cooling system and brake system.
Each of these
is covered in this manual, and the
Index will help you find them quickly.
If you’re trailering,
it’s a good idea
to review this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See
Engine Overheating on
page 5-26.

You should keep a record with all parts receipts and list Adding Equipment to the Outside of
the mileage and the date of any service work you
perform. See Part E: Maintenance Record on page 6- 16. Your Vehicle
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about
it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused.
If you
use the wrong fasteners, parts can later
break or fall off. You could be
hurt.
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment
to the
outside
of your vehicle.

Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use regular unleaded gasoline with a posted octane
of
87 or higher. If the octane is less than 87, you may
get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at
87 octane or higher as
soon as possible. Otherwise, you might damage
your engine. A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher-octane fuel is
necessary. If you are using
87 octane or higher-octane
fuel and hear heavy knocking, your engine needs
service.
Gasoline Specifications
It is recommended that gasoline meet specifications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers Association for better
vehicle performance and engine protection. Gasoline
meeting these specifications could provide improved
driveability and emission control system performance
compared
to other gasoline.
In Canada, look for the
“Auto Makers’ Choice”
label on the pump.
