Hi - first post here. I have a 2018 Prius Prime Advanced. I believe that the Intelligent Clearance Sonar system is not working (if I pull too far in the garage, or I back up and the garage door is closed, there are no warnings). I know for sure that it used to warn in the front. I am not getting any warning messages or indicator lights. We've tried turning ICS off and back on but no change. Since both the front and back aren't working, I wouldn't think it is a sensor. We wanted to check the fuse but can't figure out if there is one and if so, which one it is (I found a fuse diagram and ICS and Intelligent Clearance Sonar are not listed. Any ideas? Thanks!
Ok - I figured it out! We'd googled a ton, but I figured I would go play with the buttons. Discovered that ICS doesn't work even if it is on UNLESS parking assist is on. I swear that it does not say that in the manual, but Toyota could really use some better tech writers for the manuals.
