Head Restraints
The vehicle’s front and rear seats
have adjustable head restraints. The
head restraints provide comfort for
passengers, but more importantly
they are designed to help protect
passengers from whiplash and other
neck and spinal injuries during an
accident, especially in a rear impact
collision.
Be careful when loading
cargo through the rear pas-
senger seats to prevent dam-
age to the vehicle interior.
When cargo is loaded through
the rear passenger seats,
ensure the cargo is properly
secured to prevent it from
moving while driving.
Unsecured cargo in the pas-
senger compartment can
cause damage to the vehicle
or injury to it’s occupants.
CAUTION
To reduce the risk of serious
injury or death in an accident,
take the following precautions
when adjusting your head
restraints:
Always properly adjust the
head restraints for all passen-
gers BEFORE starting the
vehicle.
NEVER let anyone ride in a
seat with the head restraints
removed.(Continued)
(Continued)

Adjust the head restraints so
the middle of the head
restraints is at the same height
as the height of the top of the
eyes.
NEVER adjust the head
restraint position of the dri-
ver’s seat when the vehicle is
in motion.
Adjust the head restraint as
close to the passenger's head
as possible. Do not use a seat
cushion that holds the body
away from the seatback.
Make sure the head restraint
locks into position after adjust-
ing it.

This section describes how to use the
seat belts properly. It also describes
some of the things not to do when
using seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and
make sure all passengers have fas-
tened their seat belts before starting
any trip. Air bags are designed to
supplement the seat belt as an addi-
tional safety device, but they are not a
substitute. Most states require all
occupants of a vehicle to wear seat
belts.

Seat belts must be used by ALL
passengers whenever the vehi-
cle is moving. Take the following
precautions when adjusting and
wearing seat belts:
ALWAYS properly restrain
children under age 13 in the
rear seats.
(Continued)
WARNING
(Continued)
NEVER allow children to ride
in the front passenger seat. If
a child age 13 or older must be
seated in the front seat, move
the seat as far back as possi-
ble and properly restrain them
in the seat.
NEVER allow an infant or child
to be carried on an occupant’s
lap.
NEVER ride with the seatback
reclined when the vehicle is
moving.
Do not allow children to share
a seat or seat belt.
Do not wear the shoulder belt
under your arm or behind your
back.
Always wear both the shoul-
der portion and lap portion of
the lap/shoulder belt.
Do not use the seat belt if it is
twisted. A twisted seat belt
will not protect you properly
in an accident.(Continued)
(Continued)
Do not use a seat belt if the
webbing or hardware is dam-
aged.
Do not latch the seat belt into
the buckles of other seats.
NEVER unfasten the seat belt
while driving. This may cause
loss of vehicle control result-
ing in an accident.
Make sure there is nothing in
the buckle interfering with the
seat belt latch mechanism.
This may prevent the seat belt
from fastening securely.
No modifications or additions
should be made by the user
which will either prevent the
seat belt adjusting devices
from operating to remove
slack, or prevent the seat belt
assembly from being adjusted
to remove slack.

Rear center seat belt
When using the rear center seat belt,
the buckle with the "CENTER" mark
must be used.
Additional Seat Belt Safety
Precautions
Seat belt use during pregnancy
The seat belt should always be used
during pregnancy. The best way to
protect your unborn child is to protect
yourself by always wearing the seat
belt.
Pregnant women should always wear
a lap-shoulder seat belt. Place the
shoulder belt across your chest, rout-
ed between your breasts and away
from your neck. Place the shoulder
belt across the chest, routed away
from the neck. Place the lap belt below
the belt line so that it fits snugly and as
low as possible across the hips, not
across the abdomen.
Seat belt use and children
Infant and small children
All 50 states have child restraint laws
which require children to travel in
approved child restraint devices,
including booster seats. The age at
which seat belts can be used instead
of child restraints differs among
states, so you should be aware of the
specific requirements in your state,
and where you are travelling. Infant
and child restraints must be properly
placed and installed in a rear seat.
For more information refer to the
“Child Restraint Systems” section in
this chapter.
To reduce the risk of serious
injury or death to an unborn
child during an accident, preg-
nant women should NEVER
place the lap portion of the seat
belt above or over the area of
the abdomen where the unborn
child is located.
WARNING
OLF034062

2-32
Safety system of your vehicle
If the shoulder belt portion slightly
touches the child's neck or face, try
placing the child closer to the center
of the vehicle. If the shoulder belt still
touches their face or neck they need
to be returned to an appropriate
booster seat in the rear seat.
Transporting an injured person
A seat belt should be used when an
injured person is being transported.
Consult a physician for specific rec-
ommendations.
One person per belt
Two people (including children)
should never attempt to use a single
seat belt. This could increase the
severity of injuries in case of an acci-
dent.
Do not lie down
Sitting in a reclined position when
the vehicle is in motion can be dan-
gerous. Even when buckled up, the
protections of your restraint system
(seat belts and air bags) is greatly
reduced by reclining your seatback.
To reduce the chance of injuries in
the event of an accident and to
achieve the maximum effectiveness
of the restraint system, all passen-
gers should be sitting up and the
front and rear seats should be in an
upright position when the car is mov-
ing. A seat belt cannot provide proper
protection if the person is lying down
in the rear seat or if the front or rear
seats are in a reclined position.
NEVER ride with a reclined
seatback when the vehicle is
moving.
Riding with a reclined seatback
increases your chance of seri-
ous or fatal injuries in the event
of a collision or sudden stop.
Drivers and passengers should
always sit well back in their
seats, properly belted, and with
the seatbacks upright.
WARNING
Always make sure children
are wearing their seat belts
and that they are properly
adjusted before driving.
NEVER allow the shoulder
belt to contact the child's
neck or face.
Do not allow more than one
child to use a single seat belt.

Children Always in the RearChildren under age 13 must always
ride in the rear seats and must
always be properly restrained to min-
imize the risk of injury in an accident,
sudden stop or sudden maneuver.
According to accident statistics, chil-
dren are safer when properly
restrained in the rear seats than in
the front seat.Even with air bags,
children can be seriously injured
or killed. Children too large for a
child restraint must use the seat belts
provided.
All 50 states have child restraint laws
which require children to travel in
approved child restraint devices. The
laws governing the age or height/
weight restrictions at which seat
belts can be used instead of child
restraints differs among states, so
you should be aware of the specific
requirements in your state, and
where you are travelling. Child restraint systems must be
properly placed and installed in the
rear seat. You must use a commer-
cially available child restraint system
that meets the requirements of the
Federal Motor Vehicle Safety
Standards (FMVSS).
Child restraint systems are generally
designed to be secured in a vehicle
seat by lap belt portion of a
lap/shoulder belt, or by a LATCH sys-
tem in the rear seats of the vehicle.
