{CAUTION:
Both frontal and side impact airbags
inate with great force, faster than the
blink of an eye. If you are too close to an
inating airbag, as you would be if you
were leaning forward, it could seriously
injure you. Safety belts help keep you in
position for airbag ination before and
during a crash. Always wear your safety
belt even with frontal airbags. The driver
should sit as far back as possible while
still maintaining control of the vehicle.
Occupants should not lean on or sleep
against the door.
{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 43orInfants and Young Children on
page 46.

If your vehicle has a roof-mounted side impact
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 inate
properly or it might force the object into
that person causing severe injury or even
death. The path of an inating 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 side impact airbags,
never secure anything to the roof of your
vehicle by routing the rope or tie down
through any door or window opening. If
you do, the path of an inating side
impact airbag will be blocked. The path of
an inating airbag must be kept clear.

Passenger Sensing System
Your vehicle has a passenger sensing system for
the right front passenger’s position. A passenger
airbag status indicator on the instrument panel 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. If
you are using remote start to start your vehicle
from a distance, 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 182.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.

If 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.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
CAUTION: (Continued)
CAUTION: (Continued)
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
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.
83

If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint,
never put a child in a rear-facing child restraint in
the right front passenger seat unless the
passenger airbag status indicator shows off and
the airbag is off. Here is why:
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Be sure the airbag is off
before using a rear-facing child restraint
in the right front seat position.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
CAUTION: (Continued)
CAUTION: (Continued)
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be
transported in vehicles with a rear seat
that will accommodate a rear-facing child
restraint, whenever possible.
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.
84

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.
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
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 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.

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, height,
front end or side sheet metal, 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 412.
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, steering wheel,
instrument panel, ceiling headliner, ceiling and
pillar garnish trim, roof-mounted 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.
SeeCustomer Satisfaction Procedure on
page 412.
