For 1990-2009 cars only

Notice: If, when removing or reinstalling the rear seat, you do not do it carefully, you could damage the fuse center. Avoid contact between the rear seat and the fuse center whenever you remove or reinstall the rear seat.

To remove the rear seat cushion, do the following:

  1. Pull up on the front of the cushion to release the front hooks.
  2. Pull the cushion up and out toward the front of the vehicle.
  3. Slide the cushion out one of the rear doors and set it aside.

Rear Pass-Through Seat


Object Number: 822635  Size: B4

Split-Folding Rear Seat


Object Number: 822434  Size: B4

Caution: A safety belt that is not properly routed through the seat cushion or is twisted will not provide the protection needed in a crash. If the safety belt has not been routed through the seat cushion at all, it will not be there to work for the next passenger. The person sitting in that position could be badly injured. After reinstalling the seat cushion, always check to be sure that the safety belts are properly routed and are not twisted.

To reinstall the rear seat cushion, do the following:

  1. Position the seat cushion so that you can route the safety belts through the proper slots in the seat cushion.
  2. Slide the rear of the cushion up and under the seatback so the rear-locating guides hook into the wire loops on the back frame.
  3. With the seat cushion lowered, push rearward and then press down on the seat cushion until the seat cushion snaps into place.
  4. Push and pull on the seat cushion to make sure it is locked into place.
  5. Check to make sure the safety belts are properly routed and that no portion of any safety belt is trapped under the seat cushion.
