When I was using auto-cruise or AVH, I had trouble finding a place to put my right foot when I took my foot off the pedal, so I searched for a footrest for my right foot and found this "Footrest with Kick Guard" on Amazon. It seems to be made by Axis Corporation.

If you scan the QR code in the attached manual, you can watch a YouTube video on how to install it, so I followed the instructions. First, remove this screw by hand.

A gentle twist and pull removed it easily.

Remove the plastic cover.

After degreasing with the included wet wipes, remove the protective sheet and glue on the kick guard.

Drilling using the included tapping screws.

Attach the footrest to the plastic cover.

Installation complete. The footrest is slightly higher than the accelerator, so you can place your foot on it without it interfering with the accelerator.
