How to Wear Safety Belts Properly
This section is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and infants. If a child will be
riding in the vehicle, seeOlder Children on page 1-54or
Infants and Young Children on page 1-57. Follow
those rules for everyone’s protection.
It is very important for all occupants to buckle up.
Statistics show that unbelted people are hurt more often
in crashes than those who are wearing safety belts.
Occupants who are not buckled up can be thrown out of
the vehicle in a crash. And they can strike others in
the vehicle who are wearing safety belts.
First, before you or your passenger(s) wear a safety
belt, there is important information you should know.
Sit up straight and always keep your feet on the oor in
front of you. The lap part of the belt should be worn
low and snug on the hips, just touching the thighs. In a
crash, this applies force to the strong pelvic bones
and you would be less likely to slide under the lap belt.
If you slid under it, the belt would apply force on
your abdomen. This could cause serious or even fatal
injuries. The shoulder belt should go over the shoulder
and across the chest. These parts of the body are
best able to take belt restraining forces.
The shoulder belt locks if there is a sudden stop or
crash.
1-37

Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
belt except for the center front passenger position, if
equipped, which has a lap belt. SeeLap Belt on
page 1-52for more information.
The lap-shoulder belts for the rst and second row
seating positions are equipped with free-falling latch
plates. If the vehicle has a third row, the lap-shoulder
belts have either free-falling or cinching latch plates.
Use the following pictures to determine the latch
plate style:
The following instructions explain 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 the shoulder portion of a passenger belt with a
free-falling latch plate is pulled out all the way, the
child restraint locking feature may be engaged.
If this happens, let the belt go back all the way and
start again. Free-Falling Latch Plate
Cinching Latch Plate
1-45

Engaging the child restraint locking feature in the
right front seating position may affect the passenger
sensing system. SeePassenger Sensing System
on page 1-90for more information.
If the belt stops before it reaches the buckle, for
lap-shoulder belts with cinching latch plates, tilt the
latch plate and keep pulling the safety belt until
it can be buckled.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 1-53.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. See
“Shoulder Belt Height Adjustment” later in this
section for instructions on use and important safety
information.
1-46

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger positions.
Adjust the height so that the shoulder portion of the belt
is centered on the shoulder. The belt should be away
from the face and neck, but not falling off the shoulder.
Improper shoulder belt height adjustment could
reduce the effectiveness of the safety belt in a crash.
Squeeze the buttons (A)
on the sides of the height
adjuster and move the
height adjuster to the
desired position.
The adjuster can be moved up just by pushing up on
the shoulder belt guide.
After the adjuster is set to the desired position, try to
move it down without squeezing the buttons to
make sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for
front outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the safety
belt assembly. They can help tighten the safety belts
during the early stages of a moderate to severe frontal,
near frontal, or rear crash if the threshold conditions
for pretensioner activation are met. And, if the vehicle
has side impact airbags, safety belt pretensioners
can help tighten the safety belts in a side crash or a
rollover event.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle’s safety
belt system. SeeReplacing Restraint System Parts
After a Crash on page 1-99.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.

{CAUTION:
Do not attach more than one child restraint to a
single anchor. Attaching more than one child
restraint to a single anchor could cause the anchor
or attachment to come loose or even break during
a crash. A child or others could be injured. To
reduce the risk of serious or fatal injuries during a
crash, attach only one child restraint per anchor.
{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Buckle any
unused safety belts behind the child restraint so
children cannot reach them. Pull the shoulder belt
all the way out of the retractor to set the lock, if
your vehicle has one, after the child restraint has
been installed.Notice:Do not let the LATCH attachments rub
against the vehicle’s safety belts. This may damage
these parts. If necessary, move buckled safety
belts to avoid rubbing the LATCH attachments.
Do not fold the empty rear seat with a safety belt
buckled. This could damage the safety belt or
the seat. Unbuckle and return the safety belt to its
stowed position, before folding the seat.
1. Attach and tighten the lower attachments to the
lower anchors. If the child restraint does not have
lower attachments or the desired seating position
does not have lower anchors, secure the child
restraint with the top tether and the safety belts.
Refer to your child restraint manufacturer
instructions and the instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments on
the child restraint to the lower anchors.
