Lap-Shoulder Belt
All seating positions in your vehicle have a
lap-shoulder belt.
Here is how to wear a lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you
can sit up straight. To see how, see “Seats” in
the Index.
2. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
If you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just let
the belt go back all the way and start again.3. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-27.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.
1-21

4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce the
effectiveness of the safety belt in a crash. See
“Shoulder Belt Height Adjustment” later in this
section.
5. To make the lap part tight, pull up on the
shoulder belt.It may be necessary to pull stitching on the safety
belt through the latch plate to fully tighten the
lap belt on smaller occupants.
6. This safety belt has a feature that will reduce
the tension of the safety belt on the occupant’s
shoulder if the vehicle is on. To set this feature,
gently pull on the belt, or lean forward and then sit
back. The belt will retract and rest lightly against
the occupant.
When the safety belt is unbuckled or when the
vehicle is turned off, the tension reducer will
deactivate. The belt should go back out of the way.

In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions that
came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.
When the passenger sensing system has turned off
the right front passenger frontal airbag, the off
indicator on the passenger airbag status indicator
should light and stay lit when the vehicle is started.
SeePassenger Airbag Status Indicator on
page 3-59.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.4. Push the latch plate into the buckle until it clicks.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.

{CAUTION:
Children who are up against, or very close to, any
airbag when it inates can be seriously injured
or killed. Airbags plus lap-shoulder belts offer
protection for adults and older children, 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 1-28
orInfants and Young Children on page 1-31.
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 3-58
for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
1-53

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 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
will light and stay lit to remind you that the airbag is off.
SeePassenger Airbag Status Indicator on page 3-59.
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 followingthe child restraint manufacturer’s directions and refer to
Securing a Child Restraint in the Right Front Seat
Position on page 1-47.
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. SeeHead Restraints on page 1-5.
Remove any additional material from the seat such as
blankets, cushions, seat covers, seat heaters, or seat
massagers before reinstalling or securing the child
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/retaier.
The passenger sensing system is designed to enable
(may inate) 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.
