Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.The 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.
4. Push the latch plate into the buckle until it clicks.
Be sure to use the correct buckle when buckling
your lap-shoulder belt. If you nd that the latch plate
will not go fully into the buckle, see if you are
using the buckle for the center passenger position.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough, seeSafety
Belt Extender on page 1-29.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
5. Move the shoulder belt height adjuster to the height
that is right for you. Improper shoulder belt height
adjustment could reduce the effectiveness of the
safety belt in a crash. SeeShoulder Belt Height
Adjustment on page 1-21.
1-15

2. Push the latch plate into the buckle until it clicks.
The latch plates for the safety belts in each rear
seating position vary in size. If the center rear or the
left rear latch plate is inserted into the incorrect
buckle, the plate will not latch properly. Be sure you
are using the correct buckle and that the latch
plate clicks when inserted into the buckle.
When the shoulder belt is pulled out all the way, it
will lock. If it does, let it go back and start again.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-29.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.3. To make the lap part tight, pull up on the
shoulder part.
1-25

4. Buckle, position and release the safety belt as
described inRear Seat Passengers on page 1-24.
Make sure that the shoulder belt crosses the
shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out of the
guides. Slide the guide into its storage pocket on the
top of the seatback.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the driver
and right front passenger. Although you cannot see
them, they are located on the retractor part of the safety
belts. They help the safety belts reduce a person’s
forward movement in a moderate to severe frontal or
near frontal crash.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and probably other
new parts for your safety belt system. SeeReplacing
Restraint System Parts After a Crash on page 1-72.
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 will
order you an extender. It is free. 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 t. The extender has
been designed for adults. Never use it for securing
child seats. To wear it, just attach it to the regular safety
belt. For more information, see the instruction sheet
that comes with the extender.

Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
{CAUTION:
Children can be seriously injured or strangled if
a shoulder belt is wrapped around their neck
and the safety belt continues to tighten. Never
leave children unattended in a vehicle and never
allow children to play with the safety belts.
Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle’s
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.
{CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby does not
weigh much — until a crash. During a crash a
baby will become so heavy it is not possible to
hold it. For example, in a crash at only 25 mph
(40 km/h), a 12 lb (5.5 kg) baby will suddenly
become a 240 lb (110 kg) force on a person’s
arms. A baby should be secured in an
appropriate restraint.
1-33

{CAUTION:
Newborn infants need complete support,
including support for the head and neck. This
is necessary because a newborn infant’s neck
is weak and its head weighs so much compared
with the rest of its body. In a crash, an infant in a
rear-facing seat settles into the restraint, so the
crash forces can be distributed across the
strongest part of an infant’s body, the back and
shoulders. Infants always should be secured in
appropriate infant restraints.
{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle
up around the child’s abdomen. In a crash, the
belt would apply force on a body area that is
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.

Q:How Should I Use a Child Restraint?
A:A child restraint system is any device designed for
use in a motor vehicle to restrain, seat, or position
children. A built-in child restraint system is a
permanent part of the motor vehicle. An add-on
child restraint system is a portable one, which
is purchased by the vehicle’s owner. To help reduce
injuries, an add-on child restraint must be secured
in the vehicle. With built-in or add-on child
restraints, the child has to be secured within the
child restraint.
When choosing an add-on child restraint, be sure
the child restraint is designed to be used in a
vehicle. If it is, it will have a label saying that it
meets federal motor vehicle safety standards. Then
follow the instructions for the restraint. You may
nd these instructions on the restraint itself or in a
booklet, or both.
Securing an Add-on Child Restraint in
the Vehicle
{CAUTION:
A child can be seriously injured or killed in a
crash if the child restraint is not properly
secured in the vehicle. Make sure the child
restraint is properly installed in the vehicle
using the vehicle’s safety belt or LATCH
system, following the instructions that came
with that restraint, and also 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. SeeLower Anchors and Tethers for Children
(LATCH) on page 1-41for more information. A child can
be endangered in a crash if the child restraint is not
properly secured in the vehicle.
1-38

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 your vehicle — even when no
child is in it.
Securing the Child Within the Child
Restraint
There are several systems for securing the child within
the child restraint. One system, the three-point
harness, has straps that come down over each of the
infant’s shoulders and buckle together at the crotch. The
ve-point harness system has two shoulder straps,
two hip straps, and a crotch strap. A shield may take the
place of hip straps. A T-shaped shield has shoulder
straps that are attached to a at pad which rests
low against the child’s body. A shelf- or armrest-type
shield has straps that are attached to a wide, shelf-like
shield that swings up or to the side.
{CAUTION:
A child can be seriously injured or killed in a
crash if the child is not properly secured in the
child restraint. Make sure the child is properly
secured, following the instructions that came
with that restraint.
Because there are different systems, it is important to
refer to the instructions that come with the restraint.
A child can be endangered in a crash if the child is not
properly secured in the child restraint.
