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 78).
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 not 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.

it is as close to the head as possible and the
