Section 1 Seats and Restraint System
1-1 

Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
belt except for the center front passenger position, if
the vehicle has one, which has a lap belt. SeeLap Belt
on page 1-35for 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, let the belt
go back all the way and start again.
Engaging the child restraint locking feature may
affect the passenger sensing system. See
Passenger Sensing System on page 1-70for more
information.
If the belt stops before it reaches the buckle, 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 1-37.
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.
1-29 

Safety Belt Extender
If the 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  t. 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.
1-37 

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  t 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 1-29for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
Does the lap belt  t low and snug on the hips,
touching the thighs? If yes, continue. If no, return to
the booster seat.
Can proper safety belt  t 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  t 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 1-29.
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.
1-38 

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.
Airbags plus lap-shoulder belts offer protection for
adults and older children, but not for young children and
infants. Neither the vehicle’s safety belt system nor
its airbag system is designed for them. Every time
infants and young children ride in vehicles, they should
have the protection provided by appropriate child
restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.
1-41 

{CAUTION:
Never do this.
Never hold an infant or a child while riding in a
vehicle. Due to crash forces, an infant or a child
will become so heavy it is not possible to hold it
during a crash. For example, in a crash at only
25 mph (40 km/h), a 12 lb (5.5 kg) infant will
suddenly become a 240 lb (110 kg) force on a
person’s arms. An infant should be secured in an
appropriate restraint.
