Hi Folks, Brand new member here. I'm writing with a question about my 2018 Prius Two. I recently had a hitch receiver installed and have been using a hitch mounted bike rack. I quickly discovered two problems. 1. With just the rack installed and no bike, the back up sensors detect the rack as an obstruction behind the vehicle and emits a warning tone. This is annoying, but I can live with it. 2. Worse, when I actually have a bike loaded up, the car's safety features will actually slam on the brakes while I'm trying to back up. Tried parallel parking yesterday with a bike on the back and it was not fun! Is there a way to turn off either or both of these safety features while using a bike rack? Thank you!
