About Driving Your Vehicle
As with other vehicles of this type, failure to operate this
vehicle correctly may result
in loss of control or an
accident. Be sure to read the “on-pavement’‘ and
“off-road“ driving guidelines
in this manual. (See
“Driving Guidelines” and “Off-Road Driving
with your
Four-Wheel-Drive Vehicle”
in the Index.)
How to Use this Manual
Many people read their owner‘s manual from beginning
to end when they first receive their new vehicle. If you
do this,
it will help you learn about the features and
controls
for your vehicle. In this manual, you’ll find
that pictures and words work together to explain
things quickly.
Index
A good place to look for what you need is the Index
in the back of the manual. It‘s an alphabetical list of
what’s
in the manual, and the page number where
you’ll find it.
Safety Warnings and Symbols
You will find a number of safety cautions in this book.
We use a box and the word
CAUTION to tell you
about things that could hurt you
if you were to ignore
the warning.
/! CAUTION:
These mean there is something that could hurt
you or other people.
In the caution area, we tell you what the haz.ard is. Then
we tell you what to do
to help avoid or reduce the
hazard. Please read these cautions.
If you don‘t, you or
others could be hurt.

Your vehicle has a light that
comes
on as ;t reminder to
buckle up. (See “Safety
Belt Reminder Light” in
the Index.)
In most states and Canadian provinces, the law says to
wear safety belts. Here’s why: T~CJJ ~r~~r-k.
You never know if you‘ll be in a crash. If you do have a
crash, you don’t know if it will be a bad one.
A few crashes are mild. and some crashes can be so
serious that even buckled up a person wouldn’t survive.
But most crashes are
in between. In many of them,
people
who buckle up can survive and sometimes walk
away. Without belts they coulct have been badly hurt
or killed.
After more than
25 years of safety belts in vehicles,
the facts are clear.
In most crashes buckling up does
matter ... a lot!
Why Safety Belts Work
When you ride in or on anything, you go as fast as it goes.

Take the simplest vehicle. Suppose it’s just a seat on wheels.

How the Air Bag System Works
Where is the air bag?
The driver’s
air bag is in the middle of the steering wheel.
If something is between the driver and the air
bag, the bag might not inflate properly or it
might force the object into that person. The path
of an inflating air bag must be kept clear. Don’t
put anything between an occupant and the
air
bag, and don’t attach or put anything on or near
the steering wheel hub.
1-22 2

When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near-frontal crash. The air bag will inflate
only
if the impact speed is above the system's designed
"threshold level."
If your vehicle goes straight into a
wall that doesn't move or deform. the threshold level is
about
14 to 18 mph (23 to 29 km/h). The threshold level
can vary, however,
with specific vehicle design. so that
it can be somewhat above or below this range. If your
vehicle strikes something
that will move or deform, such
as a parked car. the threshold level will be higher. The
air
bag is not designed to inflate in rollovers, side
impacts or rear impacts. because inflation would not
help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
Inflation is determined
by the angle of the impact and
how quickly the vehicle slows down in frontal and
near-frontal impacts.
The air bag system
is designed to work properly under a
wide range of conditions, including off-road usage.
Observe safe driving speeds. especially
on rough terrain.
As always. wear your safety belt. See "Off-Road
Driving"
in the Index for Inore tips on off-road driving.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is
in a crash. The sensing
system triggers a release of gas from
the inflator. which
inflates
the air bag. The inflator, air bag and related
hardware
are all part of the air bag module inside the
steering wheel.
How does an air bag restrain?
In tnoderate to severe frontal or near-frontal collisions.
even belted occupants can contact the steering wheel.
The air bag supplements the protection provided by
safety belts. Air bags distribute the force
of the impact
more evenly over
the occupant's upper body. stopping
the occupant more gradually.
But air bags would not
help you in many types of collisions, including
rollovers. rear impacts and side impacts. primarily
because an occupant's motion is
not toward the air bag.
Air bags should never be regarded as anything more
than a supplement
to safety belts. and then only in
moderate to severe frontal or near-frontal collisions.
1-23

What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates,
so quickly
that some people may not even realize the air bag
inflated. Some components of the
air bag module in the
steering wheel hub
will be hot for a short time. The parts
of the bag that come into contact with you may be
warm, but not
too hot to touch. There will be some
smoke and dust coming from vents
in the deflated air
bag. Air bag inflation doesn’t prevent the driver from
seeing or from being
able to steer the vehicle, nor does it
stop people from leaving the vehicle.
When an
air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with
a history of asthma or other
breathing trouble.
To avoid this, everyone in the
vehicle should get out
as soon as it is safe to do so.
If you have breathing problems but can’t get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window
or door.

e
The air bag is designed to inflate only once. After it
inflates? you‘ll need some new parts for your air bag
system.
If you don’t get them, the air bag system
won’t be there to help protect you
in another crash.
A new system will include the air bag module and
possibly other parts. The service manual for
your
vehicle covers the need to replace other parts.
Your vehicle is equipped
with a diagnostic module,
which records information about the air bag system.
The module records information about the readiness
of the system, when the sensors are activated 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 cover for the driver’s air bag,
the bag may not work properly. You may have to
replace the air bag module.
Do not open or break
the air bag cover.

Theft
Vehicle theft is big business, especially in some cities.
Although
your vehicle has a number of theft-deter-rent
features, we know that nothing we put
on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders
or professional thieves -- so
don’t do it.
When you park your vehicle and open the driver’s door.
you’ll hear a tone reminding
you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition.
If you have an automatic transmission, taking
your
key out also locks your transmission. And
remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember
to keep your valuables out of sight.
Put them
in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle,
i1.s best to lock it up and take your keys.
But what if ~OLI have to leave your ignition key? What if
you have to leave something \duable in your vehicle?
0 Put your valuables in a storage area, like your
2 Olove box.
0 Lock all thc doors except the driver’s.

New Vehicle “Break-In”
NOTICE:
Your modern vehicle doesn’t need an elaborate
“break-in.” But it
will perform better in the long
run
if you follow these guidelines:
0 Keep your speed at 55 mph (88 km/h) or
less for the first
500 miles (805 km).
0 Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
200 miles (322 km) or so. During this time
your new brake linings aren’t yet broken in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every
time you get new brake linings.
See “Towing
a Trailer” in the Index for
more information.
0 Avoid making hard stops for the first
Don’t tow a trailer during break-in.
Ignition Positions
Use the key to turn the ignition switch to five different
positions.
C
I
ACCESSORY (A): ACCESSORY lets you use things
like the radio and the windshield wipers when the
engine
is off. Push in the key and turn it toward you.
Your steering wheel will remain locked. just as it was
before you inserted the key.
