Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
except for the center front passenger position (if
equipped), which has a lap belt. SeeLap Belt
on
page 2‑32for more information.
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 is pulled
out all the way, the child restraint locking feature
may be engaged. If this happens, just let the belt
go back all the way and start again.
Engaging the child restraint locking feature in the
right front seating position may affect the
passenger sensing system. See Passenger
Sensing System
on page 2‑67for more
information.
3. Push the latch plate into the buckle until it clicks.
If the latch plate will not go fully into the buckle,
check if the correct buckle is being used.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, see Safety Belt
Extender
on page 2‑33.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger seating 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.
Press the release
button (A) and move the
height adjuster to the
desired position. The
adjuster can be moved up
by pushing up on the
shoulder belt guide.
After the adjuster is set to the desired position, try to
move it down without pressing the release button 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 or near frontal crash if the threshold conditions
for pretensioner activation are met. And, if your vehicle
has side impact airbags, safety belt pretensioners can
help tighten the safety belts in a side crash.
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. See Replacing Restraint System Parts After a
Crash on page 2‑75.
2-28

Lap Belt
This part is only for the lap belt. To learn how to wear a
lap-shoulder belt, seeLap-Shoulder Belt on page 2‑26.
The vehicle may have a center seating position. When
you sit in the center front seating position, you have a
lap safety belt, which has no retractor.
To make the belt longer, tilt the latch plate and pull it
along the belt.
Buckle, position and release it the same way as the lap
part of a lap-shoulder belt.
To make the belt shorter, pull its free end as shown until
the belt is snug.
If the belt is not long enough, see Safety Belt Extender
on page 2‑33.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the safety
belt quickly if necessary.
If you find that the latch plate will not go fully into the
buckle, see if you are using the correct buckle. Be sure
that the latch plate clicks when inserted into the buckle.

The manufacturer's instructions that come with the
booster seat, state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder belt
until the child passes the below fit test:
.Sit all the way back on the seat. Do the knees
bend at the seat edge? If yes, continue. If no,
return to the booster seat.
.Buckle the lap-shoulder belt. Does the shoulder
belt rest on the shoulder? If yes, continue. If no, try
using the rear safety belt comfort guide. See“Rear
Safety Belt Comfort Guides” underLap-Shoulder
Belt
on page 2‑26for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
.Does the lap belt fit low and snug on the hips,
touching the thighs? If yes, continue. If no, return
to the booster seat.
.Can proper safety belt fit be maintained for length
of trip? If yes, continue. If no, return to the
booster seat.
If you have the choice, a child should sit in a position
with a lap-shoulder belt and get the additional restraint
a shoulder belt can provide. Q: What is the proper way to wear safety belts?
A:
An older child should wear a lap-shoulder belt and
get the additional restraint a shoulder belt can
provide. The shoulder belt should not cross the face
or neck. The lap belt should fit snugly below the
hips, just touching the top of the thighs. This applies
belt force to the child's pelvic bones in a crash.
It should never be worn over the abdomen, which
could cause severe or even fatal internal injuries in
a crash.
Also see “Rear Safety Belt Comfort Guides” under
Lap-Shoulder Belt on page 2‑26.
According to accident statistics, children and infants are
safer when properly restrained in the rear seating
positions than in the front seating positions.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown out
of the vehicle. Older children need to use safety belts
properly.

Securing an Add-On Child Restraint in
the Vehicle
{WARNING:
A child can be seriously injured or killed in a crash
if the child restraint is not properly secured in the
vehicle. Secure the child restraint properly in the
vehicle using the vehicle's safety belt or LATCH
system, following the instructions that came with
that child restraint and the instructions in this
manual.
To help reduce the chance of injury, the child restraint
must be secured in the vehicle. Child restraint systems
must be secured in vehicle seats by lap belts or the lap
belt portion of a lap-shoulder belt, or by the LATCH
system. See Lower Anchors and Tethers for Children
(LATCH)
on page 2‑43for more information. A child
can be endangered in a crash if the child restraint is not
properly secured in the vehicle. When securing an add-on child restraint, refer to the
instructions that come with the restraint which may be
on the restraint itself or in a booklet, or both, and to this
manual. The child restraint instructions are important,
so if they are not available, obtain a replacement copy
from the manufacturer.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and injure
people in the vehicle. Be sure to properly secure any
child restraint in the vehicle
—even when no child is
in it.
Securing the Child Within the Child
Restraint
{WARNING:
A child can be seriously injured or killed in a crash
if the child is not properly secured in the child
restraint. Secure the child properly following the
instructions that came with that child restraint.
2-41

Where to Put the Restraint
According to accident statistics, children and infants are
safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position.
We recommend that children and child restraints be
secured in a rear seat, including: an infant or a child
riding in a rear-facing child restraint; a child riding in a
forward-facing child seat; an older child riding in a
booster seat; and children, who are large enough, using
safety belts.
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.
{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating airbag. A child in a
(Continued)
WARNING: (Continued)
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inflates 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 2‑67
for additional information.

The top tether anchors are located under the covers on
the rear seatback filler panel. Flip open the cover to
access the anchors. Be sure to use an anchor located
on the same side of the vehicle as the seating position
where the child restraint will be placed.
Do not secure a child restraint in a position without a
top tether anchor if a national or local law requires that
the top tether be attached, or if the instructions that
come with the child restraint say that the top tether must
be attached.Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat. See
Where to Put the Restraint
on page 2‑42for additional
information.
Securing a Child Restraint Designed for the
LATCH System
{WARNING:
If a LATCH-type child restraint is not attached to
anchors, the child restraint will not be able to
protect the child correctly. In a crash, the child
could be seriously injured or killed. Install a
LATCH-type child restraint properly using the
anchors, or use the vehicle's safety belts to
secure the restraint, following the instructions that
came with the child restraint and the instructions
in this manual.
2-46

If the position you are
using has a fixed
headrest or head restraint
and you are using a dual
tether, route the tether
around the headrest or
head restraint.
3. Push and pull the child restraint in different directions to be sure it is secure.Securing a Child Restraint in a Rear
Seat Position
When securing a child restraint in a rear seating
position, study the instructions that came with the child
restraint to make sure it is compatible with this vehicle.
If the child restraint has the LATCH system, see Lower
Anchors and Tethers for Children (LATCH)
on
page 2‑43for how and where to install the child
restraint using LATCH. If a child restraint is secured in
the vehicle using a safety belt and it uses a top tether,
see Lower Anchors and Tethers for Children (LATCH)
on page 2‑43for 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.
If the child restraint does not have the LATCH system,
you will be using the safety belt to secure the child
restraint in this position. Be sure to follow the
instructions that came with the child restraint. Secure
the child in the child restraint when and as the
instructions say.

If more than one child restraint needs to be installed in
the rear seat, be sure to readWhere to Put the
Restraint on page 2‑42.
1. Put the child restraint on the seat.
2. 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.
3. 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.
4. Pull the rest of the shoulder belt all the way out ofthe retractor to set the lock.
2-50

5. To tighten the belt, push down on the childrestraint, pull the shoulder portion of the belt to
tighten the lap portion of the belt and feed the
shoulder belt back into the retractor. When
installing a forward-facing child restraint, it may be
helpful to use your knee to push down on the child
restraint as you tighten the belt. 6. If the child restraint has a top tether, follow the
child restraint manufacturer's instructions regarding
the use of the top tether. See Lower Anchors and
Tethers for Children (LATCH)
on page 2‑43for
more information.
7. Push and pull the child restraint in different directions to be sure it is secure.
To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position. If the
top tether is attached to a top tether anchor,
disconnect it.
