Reinstalling the Seat
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure
it is locked.
{CAUTION:
A seat that is not locked into place properly
can move around in a collision or sudden stop.
People in the vehicle could be injured. Be sure
to lock the seat into place properly when
installing it.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide
the protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.
To reinstall the seat, do the following:
1. While holding the rear of the seat up, slide the front
wheels into the slots on the oor. The front latches
should lock into place. If the latches do not lock,
try tilting the rear of the seat upward.

Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it is just a seat
on wheels.Put someone on it.
1-18

Where Are the Airbags?
The driver’s airbag is in the middle of the steering wheel.The right front passenger’s airbag is in the instrument
panel on the passenger’s side.
1-60

{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.
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.
If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level is about
9 to 17 mph (14 to 27 km/h).(The threshold level can
vary, however, with specic vehicle design, so that it can
be somewhat above or below this range.)
1-61

What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. 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.
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. 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 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 those
airbags. 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.
1-63

What Will You See After an Airbag
Inates?
After an airbag inates, it quickly deates, so quickly that
some people may not even realize the airbag inated.
Some components of the airbag module – the steering
wheel hub for the driver’s airbag, 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 the vents in the
deated airbags. Airbag ination does not prevent the
driver from seeing or being able to steer the vehicle, nor
does it stop people from leaving the vehicle.
{CAUTION:
When an airbag inates, 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.
CAUTION: (Continued)
CAUTION: (Continued)
If you have breathing problems but can not 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.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the
airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off
by using the door lock and interior lamp controls.
1-64

In many crashes severe enough to inate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.
Airbags are designed to inate only once. After they
inate, you will need some new parts for your
airbag system. If you do not get them, the airbag
system will not be there to help protect you in
another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-9.
Let only qualied technicians work on your airbag
system. Improper service can mean that an
airbag system will not work properly. See your
dealer for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, the bag
may not work properly. You may have to replace the
airbag module in the steering wheel or both the
airbag module and the instrument panel for the right
front passenger’s airbag. Do not open or break
the airbag coverings.
Airbag Off Switch
Your vehicle has a switch on the instrument panel that
you can use to turn off the right front passenger’s airbag.
