Replacing the Rear Seats

Caution: A seat that is not 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.

Caution: A safety belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be seriously injured. After raising the rear seatback, always check to be sure that the safety belts are properly routed and attached, and are not twisted.

  1. Position the seat into the open slots in both rails. Push the seat forward in the rail, hooking both seat bases onto the pins inside of the rails.
  2. Locate the hole in the rail to install the locking pins at the rear of the seat base. If the vehicle has floor mats, pull the flap that has been cut into the mat.
  3. Insert the locking pins into the seat base and push the seat to line up the pins with the base.
  4. On a three passenger seat, the pin with the black cap marked "R" must be installed on the passenger side and the pin with the gray cap marked "L" on the driver side.

    On a four passenger seat, the pins marked "R" must be installed on the half of the seat on the passenger side. The pins marked "L" must be installed on the half of the seat on the driver side.
