Securing a Child Restraint in a
Center Seat Position
If your vehicle has a center seat, you can secure a child
restraint here.
You'll be using the lap belt. Be sure to follow the
instructions that came with the child restraint. Secure
the child in the child restraint when and as the
instructions say. But do not use this position if the child
restraint interferes with shifting gears.
See Top Strap on page 1-27 if the child restraint
has one.

1. Make the belt as long as possible by tilting the latch
plate and pulling it along the belt.
2. Put the restraint on the seat.
3. Run the vehicle's safety belt through or around the
restraint. The child restraint instructions will show
you how.
