Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use
safety belts properly. It also tells you some things
you should not do with safety belts.
{CAUTION:
Do not let anyone ride where he or she
cannot wear a safety belt properly. If you
are in a crash and you are not wearing a
safety belt, your injuries can be much
worse. You can hit things inside the
vehicle or be ejected from it. You can be
seriously injured or killed. In the same
crash, you might not be, if you are
buckled up. Always fasten your safety
belt, and check that your passengers’
belts are fastened properly too.
20

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 a frontal airbag for the right front passenger.
Your vehicle may also have roof-mounted side
impact airbags designed for either side impact or
rollover deployment. Roof-mounted side impact
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 side impact
airbags, the word AIRBAG will appear on
the airbag covering on the sidewall trim near
the driver’s and right front passenger’s window.
71

{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 42orInfants and Young Children
on page 45.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 201for more information.
74

Passenger Sensing System
Your vehicle has a passenger sensing system for
the right front passenger’s position. A passenger
airbag status indicator in the rearview mirror will
be visible when you turn your ignition key to
START or RUN.The words ON and OFF, or the symbol for on
and off, will be visible during the system check.
When the system check is complete, either
the word ON or the word OFF, or the symbol for
on or the symbol for off, will be visible. See
Passenger Airbag Status Indicator on page 202.
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.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat and safety belt. The sensors are designed
to detect the presence of a properly-seated
occupant and determine if the passenger’s frontal
airbag should be enabled (may inate) or not.
Accident statistics show that children are safer
if they are restrained in the rear rather than
the front seat. We recommend that child restraints
be secured in a rear seat, including an infant
riding in a rear-facing infant seat, a child riding
in a forward-facing child seat, and an older
child riding in a booster seat.
United States
Canada
82

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 passenger’s frontal airbag, the off indicator
in the rearview mirror 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 66.
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.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job,
have it repaired. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 485for more
information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.Also look for any opened or broken airbag
covers, and have them repaired or replaced.
The airbag system does not need regular
maintenance.
Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
or the side impact airbag covering on the
ceiling near the side windows, the airbag may
not work properly. You may have to replace
the airbag module in the steering wheel, both
the airbag module and the instrument panel
for the right front passenger’s airbag, or
side impact airbag module and ceiling covering
for roof-mounted rollover airbags (if equipped).
Do not open or break the airbag coverings.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems
in your vehicle. A damaged restraint
system may not properly protect the
person using it, resulting in serious
injury or even death in a crash. To help
make sure your restraint systems are
working properly after a crash, have
them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts
or LATCH system parts?
After a very minor collision, nothing may be
necessary. But if the belts were stretched, as they
would be if worn during a more severe crash,
then you need new parts.
If the LATCH system was being used during a
more severe crash, you may need new LATCH
system parts.If belts are cut or damaged, replace them.
Collision damage also may mean you will need to
have LATCH system, safety belt or seat parts
repaired or replaced. New parts and repairs may
be necessary even if the belt or LATCH system
was not being used at the time of the collision.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system
earlier in this section.
If the frontal airbags inate you will also need to
replace the driver and front passenger’s safety belt
retractor assembly. Be sure to do so. Then the
new retractor assembly will be there to help protect
you in a collision.
After a crash you may need to replace the driver
and front passenger’s safety belt retractor
assemblies, even if the frontal airbags have not
deployed. The driver and front passenger’s safety
belt retractor assemblies contain the safety belt
pretensioners. Have your safety belt pretensioners
checked if your vehicle has been in a collision,
or if your airbag readiness light stays on after
you start your vehicle or while you are driving.
SeeAirbag Readiness Light on page 201.
