Replacing the Rear Seats
1. Lower the seat into position. Make sure the front
retainers are hooked onto the anchor pins.

sure the seat is locked in by pulling up and down on
the seat.
CAUTION:
A seat that isn't locked into place properly can
move around in a collision or sudden stop. People
in the vehicle could be injured. Be sure to lock
the seat into place properly when installing it.
