Where are the air bags?
The driver’s air bag is in the middle of the steering wheel.

Downloaded from www.Manualslib.com manuals search engine Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt isn’t long enough to fasten, your
dealer will order you an extender, It’s free. When you go
in to order it, take the heaviest coat you will wear,
so the
extender will be long enough for you. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don’t let someone else use it, and use it
only for the seat it is made to fit.
To wear it, just attach it
to the regular safety belt.
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
If you’ve had a crash, do you need new belts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new belts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even if the belt wasn’t being used at
the time
of the collision.
If your seat adjuster won’t work after a crash, the special\

part of the safety belt that goes through the seat to the
adjuster may need to be replaced.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier
in
this section.

accident. If the arrows don’t
go on at all when you
signal a turn, check for burned-out bulbs and then check
the fuse (see “Fuses and Circuit Breakers” in the Index).
Windshield Wipers
Headlamp High/Low Beam
To change the headlamps
from low-beam to
high-beam, push forward on the turn signaUmultifunction lever.
To change the headlamps from high-beam to low-beam,
pull the turn signal lever backward. When the high-beams
are on, a light on the instrument panel also
will be on.
Flash to Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
To use it, pull the turn signaVmultifunction lever toward
you until the high-beam headlamps come on, then
release the lever to turn them off. You
control the windshield wipers by moving the stalk
with the wiper symbol on it up or down.
For a single wiper cycle, push the
stalk down to MIST,
then release it. For more cycles, hold the stalk
down longer.
For steady wiping at low speed, move the stalk up to the
LO position. For high-speed wiping, move the stalk up
further, to
HI. To stop the wipers, move the stalk to OFF.
You can set the wiper speed for a long or short delay between
wipes.
This can be very useful in light rain or snow.

Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp
(Check Engine Light)
CHECK
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 and
a chime will sound 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 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 InspectiodMaintenance test.

Downloaded from www.Manualslib.com manuals search engine 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:
0
0 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:
0 Reducing vehicle speed.
Avoiding hard accelerations.
0 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
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. 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.

Downloaded from www.Manualslib.com manuals search engine 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.
Oil Pressure Warning Light
If you have a low engine oil
pressure problem, this light
will stay on after you start
your engine, or come on
and you will hear a chime
when you are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have some
other oil problem. Have it fixed immediately.
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, but the light will go out when the.engine is
running. 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.
