How To Disable The Reverse Beep In a 2007 Prius

UPDATE: I made a better video at youtu.be/YwoDDVeZZhU which will work for a 2007 Prius, too.
INSTRUCTIONS: While the car is in either "IG-ON" or "Ready" mode, push the trip/odometer button until the dashboard displays "ODO" rather than "Trip A" or "Trip B."

Turn off the car.

Make sure nobody is in the passenger seat and there is nothing heavy sitting on the seat.

With you sitting in the driver seat, leave your seatbelt off and the driver door open.

Memorize the rest of these instructions since you won't have time to read while you're doing these steps quickly:

Keep your foot on the brake the entire time.

Turn the car back on. Wait for the "Ready" light to illuminate. Within 6 seconds, push and hold the trip/odometer button for at least 10 seconds. (I could to 11.)

Continue depressing the trip/odometer button while you shift from "park" to "reverse" and then immediately press "Park" and release the trip/odometer button.

Confirm that the trip/odometer displays "b on." Immediately press the trip/odometer button, and it should say "b off." The display "b on" means "beep on," and the display "b off" means "beep off." You can toggle between those settings now by pressing the trip/odometer button.

Press the power button to turn off the car.

The next time you turn on the car and switch into reverse, there will be no beep!

Note: If the Prius's 12-volt battery becomes disconnected at any time after you disabled the reverse beep, the car will reset its defaults, and the reverse beep will return. Repeat the procedure above to disable it again.
