2. Press the button on the
passenger 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
child restraint, move the front
seat all the way forward and tilt
the seatback forward to
properly install the child
restraint per the child restraint
manufacturer instructions. See
Seat Adjustment 0 47 and
Reclining Seatbacks 0 48.
When a rear-facing child
restraint is installed properly,
the front passenger seat
cannot be used.
5. If the child restraint
manufacturer recommends
using a top tether, adjust the
top tether to its full length and
attach it to the top tether
anchor. Refer to the
instructions that came with the
child restraint and see Lower
Anchors and Tethers for
Children (LATCH System) 0 78.
6. 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.
Tilt the latch plate to adjust the
belt if needed.
