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 57).
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.
iIf PRE-SAFE® has been activated, the front
passenger’s seat will be moved to a more favor-
able seat position.
iThe memory function (page 357) lets you
store the settings for the seat positions together
with the settings for the steering wheel and the
exterior rear view mirrors.
!When moving the seat, make sure there are
no items in the footwell or behind the seats; oth-
erwise, you could damage the seats.

should check and adjust the seat height,
seat position fore and aft, and seat back-
