Do This

Don't Do This

Install a nylon tie strap to the seat back cushion latch cable.

DO NOT replace the rear seat outboard latch or cable.

Condition

Some customers may comment that the third row passenger seat will not fold down flat when using the release lever.

This condition has been found to occur primarily on vehicles built prior to October 6, 2006.

Cause

The seat back cushion latch cable may have too much slack in the cable, causing the inboard seat back cam to wedge inside the sector arm of the latch.

Correction

Remove the third row passenger seat assembly and install a nylon tie strap to the excessive slack in the seat back cushion latch cable using the procedure below:

  1. Open the liftgate to access the rear of the vehicle.
