secure the child restraint in this
position, follow the instructions that
came with the child restraint and the
following instructions:1. Always install the seat cushion extension in the right rear seat

forward-facing or rear-facing
child restraint. Also use the
seat cushion extension for
booster seats that extend past
the front edge of the seat
cushion.2. Press the button on thepassenger side headrest and
pull up.
3. Insert the headrest posts into
the holes on the front of the
passenger side seat cushion to
install the seat cushion
extension. The notches on the
post should face the passenger
side of the vehicle. Try to move
the headrest to make sure it is
locked in place.
4. Put the child restraint on the seat. When installing a rear-facing

seat all the way forward and tilt
the seatback forward to
properly install the child
restraint per the child restraint
manufacturer instructions.

anchor. Refer to the
instructions that came with the
child restraint and see Lower
Anchors and Tethers for
