A booster seat (C-D) is a child restraint designed to
improve the t of the vehicle’s safety belt system.
A booster seat can also help a child to see out the
window.
Securing an Add-On Child Restraint
in the Vehicle
{CAUTION:
A child can be seriously injured or killed in a
crash if the child restraint is not properly
secured in the vehicle. Secure the child restraint
properly in the vehicle using the vehicle’s
safety belt or LATCH system, following the
instructions that came with that child restraint
and the instructions in this manual.
To help reduce the chance of injury, the child restraint
must be secured in the vehicle. Child restraint systems
must be secured in vehicle seats by lap belts or the
lap belt portion of a lap-shoulder belt, or by the LATCH
system. SeeLower Anchors and Tethers for Children
(LATCH) on page 1-61for more information. A child can
be endangered in a crash if the child restraint is not
properly secured in the vehicle.

{CAUTION:
Frontal airbags are designed to deploy in
moderate to severe frontal and near frontal
crashes. They are not designed to in ate in
rollover, rear crashes, or in many side crashes.
Rollover capable roof-rail airbags are designed
to in ate in moderate to severe crashes where
something hits the side of your vehicle,
during a vehicle rollover, or in a severe frontal
impact. They are not designed to in ate in
rear crashes.
Everyone in your vehicle should wear a safety
belt properly — whether or not there is an
airbag for that person.
{CAUTION:
Airbags in ate with great force, faster than
the blink of an eye. Anyone who is up against,
or very close to, any airbag when it in ates
can be seriously injured or killed. Do not sit
unnecessarily close to the airbag, as you
would be if you were sitting on the edge of
your seat or leaning forward. Safety belts
help keep you in position before and during
a crash. Always wear your safety belt, even
with airbags. The driver should sit as far back
as possible while still maintaining control of
the vehicle.
Occupants should not lean on or sleep against
the door or side windows in seating positions
with roof-rail airbags.

The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side. If your vehicle has roof-rail airbags for the driver, right
front passenger, and second row outboard passengers,
they are in the ceiling above the side windows.Driver Side shown, Passenger Side similar
1-79
Page 86 of 538
If your vehicle has roof-rail airbags and a third row
passenger seat, the airbags are located in the ceiling
above the rear windows for the outboard passenger
positions in the third row.
{CAUTION:
If something is between an occupant and an
airbag, the airbag 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 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.
Never secure anything to the roof of a vehicle
with roof-rail airbags by routing a rope or tie
down through any door or window opening.
If you do, the path of an in ating roof-rail
airbag will be blocked. Driver Side shown, Passenger Side similar

What Makes an Airbag In ate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas from the
in ator. Gas from the in ator lls the airbag causing
the bag to break out of the cover and deploy. The
in ator, the airbag, and related hardware are all part
of the airbag module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with
roof-rail airbags, there are airbag modules in the
ceiling of the vehicle, near the side windows that
have occupant seating positions.
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. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.
Rollover capable roof-rail airbags are designed to
help contain the head and chest of occupants in the
outboard seating positions in the rst, second, and
third rows, if equipped with a third row seat. The rollover
capable roof-rail airbags are designed to help reduce
the risk of full or partial ejection in rollover events,
although no system can prevent all such ejections.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-81for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.

What Will You See After an
Airbag In ates?
After the frontal airbags in ate, they quickly de ate,
so quickly that some people may not even realize
an airbag in ated. Roof-rail airbags may still be at
least partially in ated for some time after they deploy.
Some components of the airbag module may be hot
for several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-83.
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 de ated airbags. Airbag in ation 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 in ates, 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
in ates, 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 may automatically
unlock the doors, turn the interior lamps on, and turn
the hazard warning ashers on when the airbags in ate.
You can lock the doors, turn the interior lamps off,
and turn the hazard warning ashers off by using the
controls for those features.
