The side impact air bags for the rear seat outboard
passenger positions are in the sides of the rear seatback
closest to the doors.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not in ate properly or it
might force the object into that person causing
severe injury or even death. The path of an
in ating air bag must be kept clear. Do not put
anything between an occupant and an air bag,
and do not attach or put anything on the
steering wheel hub or on or near any other air
bag covering. Do not let seat covers block the
in ation path of a side impact air bag.

When Should an Air Bag In ate?
The driver’s and right front passenger’s frontal air bags
are designed to in ate in moderate to severe frontal
or near-frontal crashes. But they are designed to in ate
only if the impact speed is above the system’s
designed “threshold level.”
In addition, your vehicle has “dual stage” frontal air
bags, which adjust the amount of restraint according to
crash severity. For moderate frontal impacts, these
air bags in ate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall that
doesn’t move or deform, the threshold level for the
reduced deployment is about 10 to 16 mph (18
to 26 km/h), and the threshold level for a full deployment
is about 18 to 24 mph (29 to 38.5 km/h). The threshold
level can vary, however, with speci c 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 driver’s and right front passenger’s frontal
air bags are not designed to in ate in rollovers, rear
impacts, or in many side impacts because in ation
would not help the occupant.
The side impact air bags are designed to in ate in
moderate to severe side crashes. A side impact air bag
will in ate if the crash severity is above the system’s
designed “threshold level.” The threshold level can vary
with speci c vehicle design. Side impact air bags are
not designed to in ate in frontal or near-frontal impacts,
rollovers or rear impacts, because in ation would not
help the occupant. A side impact air bag will only deploy
on the side of the vehicle that is struck.

In any particular crash, no one can say whether an air
bag should have in ated simply because of the damage
to a vehicle or because of what the repair costs were.
For frontal air bags, in ation is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal and near-frontal impacts. For side impact
air bags, in ation is determined by the location
and severity of the impact.
What Makes an Air Bag In ate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For both the
frontal and side impact air bags, the sensing system
triggers a release of gas from the in ator, which in ates
the air bag. The in ator, air bag and related hardware are
all part of the air bag modules inside the steering wheel,
instrument panel and the side of the front seatbacks and
behind the rear seatbacks closest to the door.
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. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. 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 the
frontal air bags 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 air bag.
Side impact air bags would not help you in many types
of collisions, including frontal or near frontal collisions,
rollovers, and rear 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 for the driver’s
and right front passenger’s frontal air bags, and
only in moderate to severe side collisions for the side
impact air bags.

What Will You See After an Air Bag
In ates?
After the air bag in ates, it quickly de ates, so quickly
that some people may not even realize the air bag
in ated. Some components of the air bag module – the
steering wheel hub for the driver’s air bag, the
instrument panel for the right front passenger’s bag, the
side of the seatback closest to the door for the side
impact air bags – 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 de ated
air bags. Air bag in ation doesn’t prevent the driver from
seeing or being able to steer the vehicle, nor does it
stop people from leaving the vehicle.
{CAUTION:
When an air bag in ates, 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 not get out of the vehicle after an air bag
in ates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag 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 air
bags in ate (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.

In many crashes severe enough to in ate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
Air bags are designed to in ate only once. After an
air bag in ates, 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 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 an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module,
which records information about the frontal air bag
system. The module system records information
about the readiness of the system, when the system
commands air bag in ation and driver’s safety
belt usage at deployment or near-deployment crash.
The module also records speed, engine rpm,
brake and throttle data.
Let only quali ed technicians work on your air bag
systems. Improper service can mean that an air
bag system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the air
bag covering on the driver’s, right front passenger’s
or rear seatback, the bag may not work properly.
You may have to replace the air bag module in the
steering wheel, both the air bag module and the
instrument panel for the right front passenger’s air
bag, or both the air bag module and seatback
for the side impact air bag. Do not open or break
the air bag coverings.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the air
bag systems. To purchase a service manual, seeService
Publications Ordering Information on page 7-12.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still in ate during improper
service. You can be injured if you are close to
an air bag when it in ates. Avoid yellow
connectors. They are probably part of the air
bag systems. Be sure to follow proper service
procedures, and make sure the person
performing work for you is quali ed to do so.
The air bag systems do not need regular maintenance.
Restraint System Check
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
{CAUTION:
A crash can damage the restraint systems in
your vehicle. A damaged restraint system may
not properly protect the person using it,
resulting in serious injury or even death in a
crash. To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
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 parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system was not being used at the time of
the collision.
If an air bag in ates, you will need to replace air bag
system parts. See the part on the air bag system earlier
in this section.
If the frontal air bags in ate, you will also need to
replace the driver’s and right front passenger’s safety
belt buckle assembly. Be sure to do so. Then the
new buckle assembly will be there to help protect you in
a collision.
After a crash you may need to replace the driver and
front passenger’s safety belt buckle assemblies, even if
the frontal air bags have not deployed. The driver
and front passenger’s safety belt buckle assemblies
contain the safety belt pretensioners. Have your safety
belt pretensioners checked if your vehicle has been
in a collision, or if your air bag readiness light stays on
after you start your vehicle or while you are driving.
SeeAir Bag Readiness Light on page 3-50.
