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

The person keeps going until stopped by
something. In a real vehicle, it could be the
windshield...or the instrument panel...

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 on 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 39orInfants and Young
Children on page 42.
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 182for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
68

The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.If your vehicle has a roof-mounted side impact
airbag for the driver and the person seated directly
behind the driver, it is located in the ceiling
above the side windows.
69

In any particular crash, no one can say whether
an airbag should have inated simply because
of the damage to a vehicle or because of what the
repair costs were. For frontal airbags, ination is
determined by what the vehicle hits, the angle
of the impact, and how quickly the vehicle slows
down. For roof-mounted side impact airbags,
ination is determined by the location and severity
of the impact.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is in a
crash. 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 side
impact airbags, there are also airbag modules 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. Airbags
supplement 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. Side impact airbags would
not help you in many types of collisions, including
many frontal or near frontal collisions, rollovers,
and rear impacts.
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 for vehicles with side impact airbags.
73

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 side impact airbags
may still be at least partially inated minutes after
the vehicle comes to rest. Some components of the
airbag module — the steering wheel hub for the
driver’s airbag, the instrument panel for the right
front passenger’s airbag, or the ceiling of your
vehicle near the side windows for vehicles with
roof–mounted side impact airbags — may be hot for
a short time. 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 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 prevent people from leaving the vehicle.
{CAUTION:
When an airbag inates, 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 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, turn the interior lamps on, and
turn on the hazard warning ashers when the
airbags inate. You can lock the doors again, turn
the interior lamps off, and turn the hazard warning
ashers off by using the controls for those features.
74

In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag.
Airbags are designed to inate only once. After
airbags inate, you will need some new parts
for the airbag system. If you do not get them,
the airbag system will not be there to help
protect you in another crash. A new system
will include airbag modules and possibly other
parts. The service manual for your vehicle
covers other parts that need to be replaced.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 489.
Let only qualied technicians work on the
airbag system. Improper service can mean that
your airbag system will not work properly. See
your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system. The
passenger airbag status indicator on the instrument
panel will be visible when you turn your ignition key
to RUN or START.
The passenger airbag
status indicator will
light ON and OFF for
several seconds as a
system check.
If you use remote start to start your vehicle from a
distance, if your vehicle has this feature, you may
not see the system check. When the system check
is complete, either the word ON or the word OFF
will be visible. SeePassenger Airbag Status
Indicator on page 183.
The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.
75

CAUTION: (Continued)
If you need to secure a forward-facing
child restraint in the right front seat,
always move the front passenger seat as
far back as it will go. It is better to secure
the child restraint in a rear seat.
The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag if:
The right front passenger seat is unoccupied.
The system determines that an infant is
present in a rear-facing infant seat.
The system determines that a small child is
present in a forward-facing child restraint.
The system determines that a small child is
present in a booster seat.
A right front passenger takes his/her weight off
of the seat for a period of time.
The right front passenger seat is occupied by
a smaller person, such as a child who has
outgrown child restraints.
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned
off the right front passenger’s frontal airbag, the off
indicator on the instrument panel will light and
stay lit to remind you that the airbag is off.
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 following the child restraint manufacturer’s
directions and refer toSecuring a Child Restraint in
the Right Front Seat Position on page 61.
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.
