Seats and Restraint System 1-1

Head Restraints
The vehicle’s front seats have
adjustable head restraints in all
outboard seating positions.
{CAUTION
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/spinal
injury in a crash. Do not drive until
the head restraints for all
occupants are installed and
adjusted properly.Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant’s
head. This position reduces the
chance of a neck injury in a crash.Pull the head restraint up to raise it.
To lower the head restraint, press
the release button, located on
the head restraint post on the top of
the seatback, while you push the
head restraint down.
Push down on the head restraint
after the button is released to make
sure that it is locked in place.

{CAUTION
You can lose control of the
vehicle if you try to adjust a
manual driver’s seat while the
vehicle is moving. The sudden
movement could startle and
confuse you, or make you push a
pedal when you do not want to.
Adjust the driver’s seat only when
the vehicle is not moving.A. Manual Seat Adjustment Bar
B. Driver Seat Height Adjuster.
SeeSeat Height Adjuster on
page 1-3.
C. Manual Reclining Seatback
Lever. SeeReclining Seatbacks
on page 1-8.
If the vehicle has a manual bucket
seat you can adjust the seat forward
or rearward with the bar located
under the front of the seat cushion.Lift the bar to unlock the seat. Slide
the seat to where you want it
and release the bar. Try to move
the seat with your body to be
sure the seat is locked in place.Seat Height Adjuster
If the vehicle has a manual driver
seat height adjuster, it is located on
the outboard side of the seat.
SeeManual Seats on page 1-3for
more information. To raise the
seat, move the lever upward
repeatedly until the seat is at the
desired height. To lower the
seat, move the lever downward
repeatedly until the seat is at
the desired height.

5. 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.
6. To make the lap part tight, pull
up on the shoulder belt.
It may be necessary to pull the
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, push down on
the button (A) and move the height
adjuster to the desired position.
1-24 Seats and Restraint System

You can move the height adjuster
up 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 1-62.
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 a guide for each
outboard passenger position
in the second row seat and all
passenger positions in the third row.Here is how to install a comfort
guide to the safety belt:
1. For the outboard positions,
remove the guide from its storage
clip on the interior body.
For the third row center position,
locate the comfort guide which
is located in a storage pocket,
at the top of the seat, under
the headrest on the driver’s
side of the vehicle.Outboard Positions

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 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 1-23
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 1-23.
Seats and Restraint System 1-29

{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.
{CAUTION
Never do this.
Children who are up against, or
very close to, any airbag when it
inates can be seriously injured or
killed. Never put a rear-facing
child restraint in the right front
seat. Secure a rear-facing child
restraint in a rear seat. It is also
better to secure a forward-facing
child restraint in a rear seat.If you
must secure a forward-facing child
restraint in the right front seat,
always move the front passenger
seat as far back as it will go.
Q:What are the different types of
add-on child restraints?
A:Add-on child restraints, which are
purchased by the vehicle’s
owner, are available in four basic
types. Selection of a particular
restraint should take into
consideration not only the child’s
weight, height, and age but also
whether or not the restraint will be
compatible with the motor vehicle
in which it will be used.
1-32 Seats and Restraint System

For most basic types of child
restraints, there are many
different models available. When
purchasing a child restraint,
be sure it is designed to be used
in a motor vehicle. If it is, the
restraint will have a label saying
that it meets federal motor
vehicle safety standards.
The restraint manufacturer’s
instructions that come with the
restraint state the weight
and height limitations for a
particular child restraint. In
addition, there are many kinds of
restraints available for children
with special needs.{CAUTION
To reduce the risk of neck and
head injury during a crash, infants
need complete support. This is
because an infant’s neck is not
fully developed and its head
weighs so much compared with
the rest of its body. In a crash, an
infant in a rear-facing child
restraint 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 should
always be secured in rear-facing
child restraints.
{CAUTION
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. To reduce the risk of
serious or fatal injuries during a
crash, young children should
always be secured in appropriate
child restraints.
