{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can not properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:If the child is sitting in a seat next to a window,
move the child toward the center of the vehicle.
Also seeRear Safety Belt Comfort Guides for
Children and Small Adults on page 1-27.Ifthe
child is sitting in the center rear seat passenger
position, move the child toward the safety belt
buckle. In either case, be sure that the shoulder
belt still is on the child’s shoulder, so that in a crash
the child’s upper body would have the restraint
the belts provide.

A forward-facing child seat (C-E) provides restraint for
the child’s body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.A booster seat (F-G) is a child restraint designed to
improve the t of the vehicle’s safety belt system.
Some booster seats have a shoulder belt positioner,
and some high-back booster seats have a ve-point
harness. A booster seat can also help a child to see
out the window.

7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If the airbag is off, the off indicator in the inside
rearview mirror will be lit and stay lit when the
key is turned to RUN or START.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.Airbag System
Your vehicle has a frontal airbag for the driver and
another frontal airbag for the right front passenger.
Your vehicle may also have roof-mounted airbags
designed for either side impact or rollover deployment.
Roof-mounted 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.
If your vehicle has roof-mounted airbags, the words
AIR BAG will appear on the airbag covering on
the sidewall trim near the driver’s and right front
passenger’s window.
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.

If your vehicle has a roof-mounted airbag for the driver
and the person seated directly behind the driver, it
is located in the ceiling above the side windows.If your vehicle has a roof-mounted airbag for the right
front passenger and the person directly behind that
passenger, it is located in the ceiling above the
side windows.

{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 airbags, never secure anything
to the roof of your vehicle by routing the rope
or tiedown 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.
When Should an Airbag In ate?
The driver’s and right front passenger’s frontal airbags
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 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 in ate 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 is equipped with 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 in ate at a level less than full deployment.

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 with Your Four-Wheel-Drive Vehicle on
page 4-15for 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 “rollover capable” roof-mounted airbag, the
sensing system detects that the vehicle is about to
roll over. For both frontal and roof-mounted airbags,
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 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. The airbag supplements 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 airbags
would not help you in many types of collisions,
including frontal or near frontal collisions, and rear
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 for the driver’s and right front
passenger’s frontal airbags, and only in moderate
to severe side collisions or rollovers for the roof-mounted
airbags.

What Will You See After an
Airbag In ates?
After an airbag in ates, it quickly de ates, so
quickly that some people may not even realize the
airbag in ated. Some components of the airbag
module — the steering wheel hub for the driver’s
airbag, the instrument panel for the right front
passenger’s bag or the ceiling of your vehicle near
the side windows — 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 airbags. Airbag in ation 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 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
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.
