3. Push the latch plate into the
buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, seeSafety
Belt Extender on page 1-25.
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.
5. To make the lap part tight, pull
up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.To unlatch the belt, push the button
on the buckle. The belt should return
to its stowed position. Slide the latch
plate up the safety belt webbing
when the safety belt is not in use.
The latch plate should rest on the
stitching on the safety belt, near the
guide loop on the side wall.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.

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 of the shoulder. Improper
shoulder belt height adjustment
could reduce the effectiveness of the
safety belt in a crash.
To move it down, press the release
button (A) and move the height
adjuster to the desired position.
You can move the height adjuster 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
pushing the button to make sure it
has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for the 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,
for vehicles with 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 1-60.

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 shoulder belt away
from the neck and head.There is one guide for each
outboard passenger position in the
rear seat. Here is how to install
a comfort guide to the safety belt:
1. Pull the elastic cord out from
between the edge of the
seatback and the interior body to
remove the guide from its
storage clip.2. Place the guide over the belt and
insert the two edges of the belt
into the slots of the guide.
Seats and Restraint System 1-23

3. Be sure that the belt is not twisted
and it lies at. The elastic cord
must be under the belt and the
guide on top.
{CAUTION
A safety belt that is not properly
worn may not provide the
protection needed in a crash.
The person wearing the belt could
be seriously injured. 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.
4. Buckle, position, and release
the safety belt as described
previously in this section. Make
sure that the shoulder belt
crosses the shoulder.
To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide. Pull the
guide upward to expose its storage
clip, and then slide the guide onto the
clip. Turn the guide and clip inward
and slide them in between the
seatback and the interior body,
leaving only the loop of the elastic
cord exposed.

Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to be
seriously injured if they do not wear
safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap portion
should be worn as low as possible,
below the rounding, throughout
the pregnancy.The best way to protect the fetus is to
protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
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.
Seats and Restraint System 1-25

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” under
Lap-Shoulder Belt on page 1-20
for 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 the length of the
trip? If yes, continue. If no, return
to the booster seat.
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” underLap-Shoulder Belt
on page 1-20.
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.
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.
1-26 Seats and Restraint System

{CAUTION
Never do this.
Never allow two children to wear
the same safety belt. The safety
belt can not properly spread the
impact forces. In a crash, the two
children can be crushed together
and seriously injured. A safety
belt must be used by only one
person at a time.
{CAUTION
Never do this.
Never allow a child to wear the
safety belt with the shoulder belt
behind their back. A child can be
seriously injured by not wearing
the lap-shoulder belt properly.
In a crash, the child would not be
restrained by the shoulder belt.
The child could move too far
forward increasing the chance of
head and neck injury. The child
might also slide under the lap belt.
(Continued)
CAUTION (Continued)
The belt force would then be
applied right on the abdomen.
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
Seats and Restraint System 1-27

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.
{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.
