GM Service Manual Online
For 1990-2009 cars only

The driver's side floor mat is held in place by two hooks.

Remove the floor mat by pulling up on the rear of the mat to disconnect it from the hooks.

Reinstall the floor mat by lining up the openings in the floor mat over the hooks and push it down into place.

Properly place the driver's side floor mat on the floor so that it does not block the movement of the accelerator pedal.
