Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.
69

{CAUTION:
If something is between an occupant
and an airbag, the bag might not inate
properly or it might force the object into
that person causing severe injury or even
death. The path of an inating airbag
must be kept clear. Do not put anything
between an occupant and an airbag,
and do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering. And, if your vehicle
has roof-mounted side impact airbags,
never secure anything to the roof of your
vehicle by routing the rope or tie down
through any door or window opening.
If you do, the path of an inating side
impact airbag will be blocked. The path
of an inating airbag must be kept clear.
When Should an Airbag Inate?
The driver’s and right front passenger’s frontal
airbags are designed to inate in moderate
to severe frontal or near-frontal crashes. But
they are designed to inate only if the impact
exceeds a predetermined deployment threshold.
Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a
crash is likely to be in time for the airbags to inate
and help restrain the occupants. Whether your
frontal airbags will or should deploy is not based
on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact,
and how quickly your vehicle slows down.
In addition, your vehicle has “dual stage” frontal
airbags, which adjust the restraint according
to crash severity. Your vehicle has electronic
frontal sensors, which help the sensing system
distinguish between a moderate frontal impact
and a more severe frontal impact. For moderate
frontal impacts, these airbags inate at a level
less than full deployment. For more severe
frontal impacts, full deployment occurs.
71

In any particular crash, no one can say whether
an airbag should have inated simply because
of the damage to a vehicle or because of what the
repair costs were. For frontal airbags, ination is
determined by what the vehicle hits, the angle
of the impact, and how quickly the vehicle slows
down. For roof-mounted side impact airbags,
ination is determined by the location and severity
of the impact.
The airbag 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.
SeeOff-Road Driving on page 250for tips on
off-road driving.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is in a
crash. In the case of a roof-mounted rollover airbag,
the sensing system detects that the vehicle is about
to roll over or has been in a moderate to severe
side impact. The sensing system triggers a release
of gas from the inator, which inates the airbag.The inator, airbag, and related hardware are all
part of the airbag modules inside the steering wheel
and in the instrument panel in front of the right front
passenger. For vehicles with roof-mounted rollover
airbags, the airbag modules are located in the
ceiling of the vehicle, near the side windows.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact
the steering wheel or the instrument panel.
In moderate to severe side collisions, even belted
occupants can contact the inside of the vehicle.
Airbags supplement the protection provided
by safety belts. Airbags distribute the force of the
impact more evenly over the occupant’s upper
body, stopping the occupant more gradually.
But the frontal airbags would not help you in
many types of collisions, including rollovers, rear
impacts, and many side impacts, primarily because
an occupant’s motion is not toward the airbag.
Roof-mounted rollover airbags would not help
you in many types of collisions, including many
frontal or near frontal collisions, and rear impacts.
73

Airbags 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 for the driver’s and right
front passenger’s frontal airbags, and only
in moderate to severe side collisions or rollovers
for vehicles with roof-mounted rollover airbags.
What Will You See After an Airbag
Inates?
After a frontal airbag inates, it quickly deates,
so quickly that some people may not even realize
an airbag inated. Roof-mounted rollover airbags
may still be at least partially inated minutes after
the vehicle comes to rest. Some components
of the airbag module — the steering wheel hub for
the driver’s airbag, the instrument panel for the
right front passenger’s airbag, and the area along
the ceiling of the vehicle near the side windows
for vehicles with roof–mounted side impact
airbags — may be hot for a short time. The parts
of the airbag that come into contact with you may
be warm, but not too hot to touch.There may be some smoke and dust coming from
the vents in the deated airbags. Airbag ination
does not prevent the driver from seeing out of the
windshield or being able to steer the vehicle, nor
does it prevent people from leaving the vehicle.
{CAUTION:
When an airbag inates, there may be
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 cannot get out of the vehicle
after an airbag inates, then get fresh
air by opening a window or a door. If you
experience breathing problems following
an airbag deployment, you should seek
medical attention.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors.
If you have any questions about this,
you should contact Customer Assistance
before you modify your vehicle. The phone
numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure
on page 448.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, rollover sensor
module, instrument panel, steering wheel,
ceiling headliner, ceiling and pillar garnish trim,
roof-mounted rollover airbag modules, or
airbag wiring can affect the operation of the
airbag system. If you have questions, call
Customer Assistance. The phone numbers
and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 448.

Restraint System Check
Checking the 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. SeeCare of Safety Belts on page 409
for more information.
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 airbag
covers, and have them repaired or replaced. The
airbag system does not need regular maintenance.Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
or the side impact airbag covering (if equipped)
on the ceiling near the side windows, the airbag
may not work properly. You may have to replace
the airbag module in the steering wheel, both
the airbag module and the instrument panel
for the right front passenger’s airbag, or side
impact airbag module and ceiling covering for
roof-mounted side impact airbags (if equipped.)
Do not open or break the airbag coverings.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Keep your speed at 55 mph (88 km/h)
or less for the rst 500 miles (805 km).
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake, or slow, the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not 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.
Do not tow a trailer during break-in.
SeeTowing a Trailer on page 297for the
trailer towing capabilities of your vehicle
and more information.
Following break-in, engine speed and load
can be gradually increased.
Ignition Positions
With the key in the
ignition switch, you can
turn to four different
positions.
LOCK (A):This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. It will locks the steering wheel on
manual transmission vehicles when the key is
removed. It is a theft-deterrent feature. You
will only be able to remove your key when the
ignition is turned to LOCK.
If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the
shift lever is in PARK (P).
101

Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. If none of this
works, then your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in
which you can operate your electrical accessories
or items plugged into the accessory power
outlets. On automatic transmission vehicles, this
position unlocks the ignition. On manual
transmission vehicles, it unlocks the ignition and
steering wheel. Use this position if your vehicle
must be pushed or towed.
ON (C):This is the position that the switch returns
to after you start your engine and release the
switch. The switch stays in ON when the engine is
running. But even when the engine is not running,
you can use ON to operate the electrical
accessories and to display some instrument
panel cluster warning and indicator lights.The transmission is also unlocked in this position on
automatic transmission vehicles.
The battery could be drained if you leave the key in
the ACC or ON position with the engine off. You
may not be able to start your vehicle if the battery is
allowed to drain for an extended period of time.
START (D):This is the position that starts the
engine. When the engine starts, release the key.
The ignition switch returns to ON for driving.
When the engine is not running, ACC and ON
allows you to operate the electrical accessories,
such as the radio or items plugged into the
accessory power outlets.
A warning tone will sound if you open the driver’s
door when the ignition is in ACC or LOCK and
the key is in the ignition.
Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transmission. Also, always
remember to lock the doors.
102

Hazard Warning Flashers
Your hazard warning ashers let you warn others.
They also let police know you have a problem.
Your front and rear turn signal lamps will ash
on and off.
The hazard warning
asher button is located
in the center of the
instrument panel.
Your hazard warning ashers work no matter
what position your key is in, and even if the key
is not in the ignition switch.
Press the button to make the front and rear turn
signal lamps ash on and off. Press the button
again to turn the ashers off.
When the hazard warning ashers are on, your
turn signals will not work.
Other Warning Devices
If you carry reective triangles, you can set one
up at the side of the road about 300 feet (100 m)
behind your vehicle.
Horn
To sound the horn, press the horn symbol on the
steering wheel pad.
Tilt Wheel
A tilt wheel allows the steering wheel to be adjusted
before driving. It can be raised to allow more room
for the driver to enter and exit the vehicle.
154

The tilt lever is located on the left side of the
steering column, under the turn signal lever.
To tilt, hold the steering wheel and pull the tilt lever
toward you. Move the wheel to a comfortable
level, then release the tilt lever to lock the wheel
in place.
Do not adjust the steering wheel while driving.
