Warning!
According to accident statistics, children are
safer when properly restrained in the rear seating positions than in the front seating
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 additional
information, see “Children in the vehicle”.
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.
Rear seat adjustment G
Warning!
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and seat
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Never place hands under the seat or near any
moving parts while a seat is being adjusted.
After adjusting rear seats, make sure
R the seats are properly locked
R the seat backrests are in an upright position
and are properly locked
An outboard second-row seat is properly
locked only when lock status indicator : is
in hinged position and red marking ; is
barely visible.
If a seat and seat backrest are not properly
locked, the seat could move forward and the
seat backrest could fold. You could slide
under the seat belt during braking, vehicle 86
