Next, lift up the panel covering the spare tire compartment using the small handle located beneath the carpet directly behind the door's latch. This will reveal 2 to 3 bolts holding down the upholstery to the car's metal frame.

(The number may vary due to model year or alterations) My vehicle only has 2 but still has a hole for a bolt that I have placed in it to demonstrate.

Use the 11 mm wrench to undo the bolts and release the bottom of the part. Make sure to keep all of the bolts and plugs somewhere they will not be lost before reassembly. I recommend a Tupperware container or a bowl.
