Seating and safety restraints
Ford recommends the use of a child safety seat having a top tether
strap. Install the child safety seat in a seating position which is capable
of providing a tether anchorage. For more information on top tether
straps, refer to Attaching safety seats with tether straps.
Carefully follow all of the manufacturer's instructions included
with the safety seat you put in your vehicle. If you do not install
and use the safety seat properly, the child may be injured in a sudden
stop or collision.
Installing child safety seats in combination lap and shoulder belt
seating positions
Air bags can kill or injure a child in a child seat. NEVER place a
rear-facing child seat in front of an active air bag. If you must
use a forward-facing child seat in the front seat, move the seat all the
way back.
1. Position the child safety seat in a
seat with a combination lap and
shoulder belt.
Children 12 and under should be properly restrained in the rear
seat whenever possible.
