Removing Interior Trim Panels.

[deicustoms1]

Most of the panels use just clips. The door sill pieces use clips, just pull them up.

The piece by the foot rest likely just uses clips, check for a screw though. If you need to remove the piece above the pedals for easier access, you will need to remove the end panel first, which just uses clips, then remove a couple screws under the hood release.

Not positive on the rear panel, but it's the same concept, look to see how it's connected, and it should be easy to remove.
