Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They
use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3

6. To tighten the belt, push down on the child
restraint, pull the shoulder portion of the belt
to tighten the lap portion of the belt and
feed the shoulder belt back into the retractor.
If you are using a forward-facing child
restraint, you may nd it helpful to use your
knee to push down on the child restraint
as you tighten the belt. You should not be able
to pull more of the belt from the retractor
once the lock has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.8. If your vehicle has the passenger sensing
system and the airbag is off, the off indicator
in the instrument panel 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.

{CAUTION:
Anyone who is up against, or very close
to, any airbag when it inates 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 227for more information.
92

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.
93

What Makes an Airbag Inate?
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 or side impact. 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.
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.
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 rollover airbags would not help you
in many types of collisions, including many
frontal or near frontal collisions, and rear impacts,
primarily because an occupant’s motion is not
toward the airbag. 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 impacts
and rollover events.
98

What Will You See After an Airbag
Inates?
After a frontal airbag inates, it quickly deates, so
quickly that some people may not even realize the
airbag inated. Roof-mounted rollover airbags
deate more slowly and may still be at least partially
inated minutes after the vehicle comes to rest.
Some components of the airbag module may be hot
for a short time. These components include the
steering wheel hub for the driver’s frontal airbag
and the instrument panel for the right front
passenger’s frontal airbag. For vehicles with
roof-mounted rollover airbags, the ceiling of your
vehicle near the side windows may be hot. 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 out of the windshield 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. If
you have breathing problems but cannot
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 may 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.
99

If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could
be because that person is not sitting properly in the
seat. If this happens, turn the vehicle off and ask
the person to place the seatback in the fully upright
position, then sit upright in the seat, centered on the
seat cushion, with the person’s legs comfortably
extended. Restart the vehicle and have the person
remain in this position for about two minutes. This
will allow the system to detect that person and then
enable the passenger’s airbag.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system.
If this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front
passenger’s seat may not have the
protection of the frontal airbag. See
Airbag Readiness Light on page 227for
more on this, including important safety
information.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, front end or
side sheet metal or height, they may keep the
airbag system from working properly. Also, the
airbag system may not work properly if you
relocate any of the airbag sensors. If you have
any questions about this, you should contact
Customer Assistance before you modify your
vehicle. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure
on page 572.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the front
seats, safety belts, the airbag sensing and
diagnostic module (located under the driver’s
seat), rollover sensor module (located under
the center console), instrument panel, steering
wheel, ceiling headliner, ceiling and pillar
garnish trim, roof-mounted rollover airbag
modules or airbag wiring can affect the
operation of the airbag system. If you have
questions, call Customer Assistance. The
phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 572.
