G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant or child restraint recommended
for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt fully in
accordance with the child seat manufactur-
er’s instructions.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.

(
page 121).
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that it is as close to
the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.i
When moving the seat fore or aft after ad-
justing the head restraints, the head restraints
may readjust automatically.

85 Safety and Security
Occupant safety


A child in a rear-facing child restraint on
the passenger seat will be seriously in-
jured or even killed if the passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology in-
stalled in your vehicle.


If you install a rear-facing child restraint
on the passenger seat, make sure that
the 5/indicator lamp is illumi-
nated, indicating that the passenger
front air bag is deactivated. Should the
5/ indicator lamp not illuminate
or go out while the restraint is installed,
please check installation. Periodically
check the 5/ indicator lamp
while driving to make sure the
5/indicator lamp is illuminated.
If the 5/ indicator lamp goes out
or remains out, do not transport a child
on the passenger seat until the system
has been repaired. A child in a rear-fac-
ing child restraint on the passenger seat
will be seriously injured or even killed if
the passenger front air bag inflates.


If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible,
use the proper child restraint recom-
mended for the age, size and weight of
the child, and secure child restraint with
the vehicle’s seat belt according to the
child seat manufacturer’s instructions.
For children larger than the typical
12-month-old child, the passenger front
air bag may or may not be activated
(page 74).
Warning!
G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
Warning!
G
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion the shoulder belt across chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper belt po-
sitioning for children over 41 lbs until they
reach a height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and cause an accident
and/or serious personal injury.
