Because your vehicle has a right front passenger air
bag, always move the seat as farback as it will go
before securing a forward-facing child restraint. (See
"Seats" in the Index.)
Put the restraint on the seat. Follow the instructions
for the child restraint.
Secure the child in the child restraint as the
instructions say.
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.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.
5. 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.
