if the child restraint has one. 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.
1. If your vehicle has a passenger air bag and an air
bag off switch, and you are using a rear-facing child
restraint in this seat, make sure the air bag is
turned off. See Air Bag Off Switch on page 7-70. If
your child restraint is forward-facing, always
move the seat as far back as it will go before
securing it in this seat. See "Seats" in the Index.
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
