{CAUTION:
A seat that is not locked into place properly
can move around in a collision or sudden
stop. People in the vehicle could be injured.
Be sure to lock the seat into place properly
when installing it.
4. Push and pull on the seat to make sure it is

to be sure that the safety belts are properly
routed and attached, and are not twisted.
7. Make sure the safety belts are returned to the
original position over the seatbacks.

Lap-Shoulder Belt
All seating positions in your vehicle have a lap-shoulder
except for the center front passenger position, if your
vehicle has one, which has a lap belt. SeeLap Belt
on page 1-48for more information.
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.
Engaging the child restraint locking feature
may affect the passenger sensing system.
SeePassenger Sensing System on page 1-85.3. Push the latch plate into the buckle until it clicks.
If you nd that the latch plate will not go fully into
the buckle, see if you are using the correct buckle.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough, seeSafety
Belt Extender on page 1-50.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.

CAUTION: (Continued)
A child in a forward-facing child restraint can
be seriously injured or killed if the right front
passenger airbag inates and the passenger
seat is in a forward position.
Even if the passenger sensing system has
turned off the right front passenger frontal
airbag, no system is fail-safe. No one can
guarantee that an airbag will not deploy under
some unusual circumstance, even though
it is turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you 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.
SeePassenger Sensing System on page 1-85
for additional information.If your child restraint has the LATCH system, seeLower
Anchors and Tethers for Children (LATCH) on page 1-61
for how to install your child restraint using LATCH. If you
secure a child restraint using a safety belt and it uses a
top tether, seeLower Anchors and Tethers for Children
(LATCH) on page 1-61for top tether anchor locations.
Do not secure a child seat in a position without a top
tether anchor if a national or local law requires that the
top tether be anchored, or if the instructions that come
with the child restraint say that the top strap must be
anchored.
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’s frontal airbag,
the off indicator on the passenger airbag status
indicator should light and stay lit when you start
the vehicle. SeePassenger Airbag Status Indicator
on page 3-38.
2. Put the child restraint on the seat.
1-73

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten
the lap portion of the belt and feed the shoulder
belt back into the retractor. If you are using a
forward-facing child restraint, you may nd it
helpful to use your knee to push down on the
child restraint as you tighten the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.If the airbag is off, the off indicator in the passenger
airbag status indicator will come on and stay on when
the vehicle is started.
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.
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/retailer.
To remove the child restraint, unbuckle the vehicle’s
safety belt and let it go back all the way.
