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
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.
-
These ..lean there is something that could hurt
you
or other people.
In the caution area, we tell you what the hazard 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 a 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:
They work.
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 could have been badly hurt
or killed.
After more than
30 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.

How the Air Bag System Works
Where are the air bags?
The driver’s air bag is in the middle of the
steering wheel. The
right front passenger’s air bag is in the instrument
panel on the passenger’s side.

When should an air bag inflate?
I
If something is between an occupant and an 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 an air
bag, and don’t attach or put anything on the
steering wheel hub or on or near any other air
bag covering.
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 or
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 more 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 modules inside the
steering wheel and in the instrument panel in front
of the
right front passenger.
How does an air bag restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement 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
those air bags. 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.
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
-- the steering wheel hub for the driver’s air bag,
or the instrument panel for the right front passenger’s
bag
-- 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 bags. 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.

Air bags are designed to inflate only once. After they
inflate, you’ll need
some new parts for your air bag
system. If you don’t get them, the air bag syste,m
won’t be there to help protect you
in another crash.
A new system will include air bag modules 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.
I 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.
If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher -- or if water enters
your vehicle and soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you start your vehicle, the damage could make the air
bags inflate, even if there’s no crash. You would have to
replace
the air bags as well as the sensors and related
parts.
If your vehicle is ever in a flood, or if it’s exposed
to water that soaks the carpet, you can avoid needless
repair costs
by turning off the vehicle immediately.
Don’t let anyone start the vehicle, even to tow
it, unless
the battery cables are first disconnected.

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 chime 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 and 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, it’s best to lock it up and take your keys.
But what
if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your
glove box.
Lock all the doors except the driver’s.
Content Theft-Deterrent
Your vehicle is equipped
with
a Content
Theft-Deterrent
SECURITY alarm system.
With this system, the SECURITY light will flash as
you
open the door (if your ignition is off).
This light reminds you to activate the theft-deterrent
system. Here’s how
to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The SECURITY
light should come
on and stay on.
3. Close all doors. The SECURITY light should go off
after approximately
30 seconds. The alarm is not
armed until the SECURITY light goes off.
If a door is opened without the key or the remote keyless
entry transmitter, the alarm will go
off. Your vehicle’s
high-beam headlamps will flash
and the horn will sound
for
30 seconds, then will turn off to save the battery power.
