Infant and child restraint systems
Only use a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt and the rear center seat belt have
special seat belt retractors for secure fas-
tening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat b elt retractor is acti-
vated. The seat belt is now locked. Push
down on child restraint to take up any
slack.Warning!G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could
injure themselves on parts of the vehicle

excessive exposure to extreme heat or
cold
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for exampl e, could become very
hot, and the child could be burned on these
parts.
If children open a door, they could
injure other persons

Seats
Rear seatsHead restraint height
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For addi-
tional information, see “Children in the vehi-
cle” (
page 77).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is no t properly secured in
the child restraint.
Warning!G
Always lock seat backrest in its upright
position when rear seat bench is occupied
by passengers, or cargo is being carried
behind the rear seat bench.
To help avoid personal injury from smaller
objects flying in the occupant area during a
collision or sudden maneuver, always use
partition net when transporting cargo
(
page 210).
Warning!G
Do not drive the vehicle without the seat
head restraints installed when the rear seat
bench is occupied. Head restraints are
intended to help reduce injuries during an
accident.
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way 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 fo r injury to the head
and neck in the event of an accident or
similar situation.
