Installing child safety seats in cinch tongue combination lap and
shoulder belt seating positions (rear center position only)
The belt webbing below the tongue is the lap portion of the combination
lap/shoulder belt, and the belt webbing above the tongue is the shoulder
belt portion of the combination lap/shoulder belt.
Note: Although the child seat illustrated is a forward facing child seat,
the steps are the same for installing a rear facing child seat.
1. Position the child safety seat in a
seat with a combination lap and
shoulder belt.
WARNING: Airbags can kill or injure a child in a child seat. If
you must use a forward-facing child seat in the front seat, move
seat all the way back.
WARNING: Rear facing child seats should NEVER be placed in
front of an active airbag.
2. Slide the tongue up the webbing.
