    Anybody knows how to troubleshoot if my audio alarm stopped working, I mean when you back out too close to some object it's not beeping/screaming. Before it worked OK.

    All other options work OK, let say if you back out too close car stopped automatically but no any audio.
    I went thru all option, everything looks like ON.

    Thanks

    Had the same issue. The dealer said that I turned it off (?) and the dealer turned it back on. Like you I looked to everything and couldn’t find what I had done. I think it was one of the buttons, not an option on the dash. Good luck.

    According to the Owners Manual, which is huge but has all the answers, on page 362 it says the menu item to enable/disable the intuitive parking assist function is located in the larger menu in the multi-information display. That is the dashboard screen on the right which is accessed with the left/right arrows in the keypad on the right side of the steering wheel. Then it refers you back to page 151 where it describes how to get to that switch, which would take me a whole other paragraph to describe. Unlike other functions in the vehicle which re-enable by turning the vehicle off then back on, the parking assist function stays off when turned off. The Owners Manual I refer to is for the 2021 model year. The OP avatar says their vehicle is a Gen II (2008), so as always YMMV.
