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.
{CAUTION:
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, people riding in these areas
are more likely to be seriously injured or
killed. Do not allow people to ride in any
area of your vehicle that is not equipped
with seats and safety belts. Be sure
everyone in your vehicle is in a seat and
using a safety belt properly.
Your vehicle has indicators to remind you and your
passengers to buckle your safety belts. SeeSafety
Belt Reminder Light on page 171andPassenger
Safety Belt Reminder Light on page 172.

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.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. 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 headliner near the
driver’s and right front passenger’s window.
Airbags are designed to supplement the protection
provided by safety belts. Even though today’s
airbags are also designed to help reduce the risk
of injury from the force of an in ating bag, all
airbags must in ate very quickly to do their job.

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 172for more information.Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
67

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 words ON and OFF, or the symbol for on and
off, will be visible during the 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, or the symbol for on or the symbol for
off, will be visible. SeePassenger Airbag Status
Indicator on page 173.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. 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 in ate) 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.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.

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 60.
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.
The passenger sensing system is designed to
enable (may in ate) the right front passenger’s
frontal airbag anytime the system senses
that a person of adult size is sitting properly in the
right front passenger’s seat. When the passenger
sensing system has allowed the airbag to be
enabled, the on indicator will light and stay lit to
remind you that the airbag is active.For some children who have outgrown child
restraints and for very small adults, the passenger
sensing system may or may not turn off the
right front passenger’s frontal airbag, depending
upon the person’s seating posture and body build.
Everyone in your vehicle who has outgrown
child restraints should wear a safety belt
properly — whether or not there is an airbag for
that person.
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.
76

You may want to consider not using seat covers or
other aftermarket equipment if your vehicle has the
passenger sensing system. SeeAdding Equipment
to Your Airbag-Equipped Vehicle on page 79for
more information about modi cations that can affect
how the system operates.
The passenger sensing system may suppress the
airbag deployment when liquid is soaked into
the seat. If this happens, the off indicator in the
passenger airbag status indicator and the
airbag readiness light on the instrument panel will
be lit. The system should resume normal
operation after the seat is allowed to dry. If the
system operates incorrectly after the seat
has dried, have your dealer check the system.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system in
several places around your vehicle. You do
not want the system to in ate while someone is
working on your vehicle. Your dealer and the
service manual have information about servicing
your vehicle and the airbag system. To purchase a
service manual, seeService Publications
Ordering Information on page 511.
