{WARNING:
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a collision,
people riding in these areas are more likely to
be seriously injured or killed. Do not allow people
to ride in any area of your vehicle that is not
equipped with seats and safety belts. Be sure
everyone in your vehicle is in a seat and using a
safety belt properly.
This vehicle has indicators as a reminder to buckle the
safety belts. See Safety Belt Reminders
on page 4‑27for additional information. In most states and in all Canadian provinces, the law
requires wearing safety belts. Here is why:
You never know if you will be in a crash. If you do have
a crash, you do not know if it will be a serious one.
A few crashes are mild, and some crashes can be
so serious that even buckled up, a person would not
survive. But most crashes are in between. In many of
them, people who buckle up can survive and sometimes
walk away. Without safety belts, they could have been
badly hurt or killed.
After more than 40 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up does
matter ... a lot!

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 2‑47for more information.
The lap‐shoulder belts for the first 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:
Free-Falling Latch Plate
Cinching Latch Plate
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.

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. See Replacing Restraint System Parts After a
Crash on page 2‑94.
Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort
guides. If not, they are available through your dealer/
retailer. The guides may provide added safety belt
comfort for older children who have outgrown booster
seats and for some adults. When installed and properly
adjusted, the comfort guide positions the belt away from
the neck and head.

To make the belt shorter, pull its free end as shown until
the belt is snug.
If the belt is not long enough, seeSafety Belt Extender
on page 2‑48.
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.
Safety Belt Extender
If the vehicle's safety belt will fasten around you, you
should use it.
But if a safety belt is not long enough, your dealer/
retailer will order you an extender. When you go in to
order it, take the heaviest coat you will wear, so the
extender will be long enough for you. To help avoid
personal injury, do not let someone else use it, and use
it only for the seat it is made to fit. The extender has
been designed for adults. Never use it for securing child
seats. To wear it, attach it to the regular safety belt. For
more information, see the instruction sheet that comes
with the extender.

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.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 2‑40for 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.

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 2‑59for 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.
