Airbag System
Your vehicle has a frontal airbag for the driver
and a frontal airbag for the right front passenger.
Your vehicle also has roof-mounted rollover
airbags designed for either side impact or rollover
deployment. Roof-mounted rollover airbags are
available for the driver and the passenger seated
directly behind the driver and for the right front
passenger and the passenger seated directly
behind that passenger.
For roof-mounted rollover airbags, the word
AIRBAG will appear on the airbag covering on the
ceiling above the sidewall trim near the driver’s
and right front passenger’s window and the
second row outside seating positions.
Also, if your vehicle has a third row passenger
seat, your vehicle will have third row roof-mounted
rollover airbags.
Frontal airbags are designed to help reduce
the risk of injury from the force of an in ating
frontal airbag. But these airbags must in ate very
quickly to do their job and comply with federal
regulations.Here are the most important things to know about
the airbag system:
{CAUTION:
You can be severely injured or killed in a
crash if you are not wearing your safety
belt — even if you have airbags. Wearing
your safety belt during a crash helps
reduce your chance of hitting things
inside the vehicle or being ejected from it.
Airbags are “supplemental restraints” to
the safety belts. All airbags are designed
to work with safety belts but do not
replace them.
Frontal airbags for the driver and right
front passenger are designed to deploy in
moderate to severe frontal and near frontal
crashes.
CAUTION: (Continued)
90

CAUTION: (Continued)
They are not designed to in ate in
rollover, rear crashes, or in many side
crashes. And, for some unrestrained
occupants, frontal airbags may provide
less protection in frontal crashes than
more forceful airbags have provided in
the past.
Roof-mounted rollover 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. If your
vehicle has roof-mounted airbags, they
are designed to provide both side impact
protection and rollover protection.
Everyone in your vehicle should wear a
safety belt properly — whether or not there
is an airbag for that person.
{CAUTION:
Both frontal and roof-mounted rollover
airbags in ate with great force, faster than
the blink of an eye. If you are too close to
an in ating airbag, as you would be if you
were leaning forward, it could seriously
injure you. Safety belts help keep you in
position for airbag in ation before and
during a crash. Always wear your safety
belt even with frontal 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 in the rst or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof-mounted
rollover airbags.

{CAUTION:
Anyone who is up against, or very close
to, any airbag when it in ates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer the best
protection for adults, but not for young
children and infants. Neither the vehicle’s
safety belt system nor its airbag system is
designed for them. Young children and
infants need the protection that a child
restraint system can provide. Always
secure children properly in your vehicle.
To read how, seeOlder Children on
page 61orInfants and Young Children on
page 64.
Occupants should not lean on or sleep
against the door in the rst or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof-mounted
rollover airbags.There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 229for more information.

The roof-mounted rollover airbag for the driver and
the person seated directly behind the driver is
located in the ceiling above the side windows.The roof-mounted rollover airbag for the right front
passenger and the person directly behind that
passenger is located in the ceiling above the side
windows.

If your vehicle has a third row seat, the
roof-mounted rollover airbag is located in the
ceiling above the rear windows for the outside
passenger positions.
{CAUTION:
If something is between an occupant and
an airbag, 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 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 rollover 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 in ating side
impact airbag will be blocked. The path of
an in ating airbag must be kept clear.

Frontal airbags may in ate at different crash
speeds. For example:
If the vehicle hits a stationary object, the
airbags could in ate at a different crash speed
than if the vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could in ate at a different crash
speed than if the vehicle hits an object that
does not deform.
If the vehicle hits a narrow object (like a pole)
the airbags could in ate at a different crash
speed than if the vehicle hits a wide object
(like a wall).
If the vehicle goes into an object at an angle
the airbags could in ate at a different crash
speed than if the vehicle goes straight into the
object.
The frontal airbags (driver and right front
passenger) are not intended to in ate during
vehicle rollovers, rear impacts, or in many side
impacts.Your vehicle has a seat position sensor which
enables the sensing system to monitor the
fore and aft position of the driver’s seat. Seat
position sensors provide information that is used
to determine if the airbags should deploy at a
reduced level or at full deployment.
Your vehicle has roof-mounted rollover airbags
and a rollover sensor. SeeAirbag System on
page 90. These “rollover capable” airbags
are intended to in ate in moderate to severe side
crashes, during a rollover or in a severe frontal
impact. A roof-mounted rollover airbag 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. Roof-mounted rollover
airbags are not intended to in ate in rear
impacts. Both roof-mounted rollover airbags will
deploy when either side of the vehicle is struck or
during a rollover, or in a severe frontal impact.

In any particular crash, no one can say whether
an airbag should have in ated simply because
of the damage to a vehicle or because of what the
repair costs were. For frontal airbags, in ation is
determined by what the vehicle hits, the angle
of the impact, and how quickly the vehicle
slows down. For roof-mounted rollover airbags,
in ation is determined by the location and severity
of the impact or a rollover event.
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 359for tips on
off-road driving.What Makes an Airbag In ate?
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 severe
frontal impact. The sensing system triggers a
release of gas from the in ator, which in ates the
airbag. The in ator, 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.
If your vehicle has a third row seat with
roof-mounted rollover airbags, the airbag modules
are located inside the rear-most pillar trim and
above in the ceiling above the xed rear glass.
