2020 Camry SE Backup radar not beeping anymore
 

My wife occasionally drives my car and has a bad habit of changing things and pressing buttons and this feature in the car has stopped working so I am wondering if she has turned off this feature.

so when I back up, the screen comes on and the proximity squares are there but no sound is heard the closer you get to an object/car from behind. I have not been able to locate the parking assist button (doesn’t have one) and have been through all of the menus.

I also noticed yesterday, when I was low on gas, the low gas icon was lit on the dash but I never had an audible notification. Might be related?

help.
