Just bought a used 2021 touring. It beeped whenever pushed the unlock button and walked away. Suddenly it stopped beeping but the doors and buttons function. How can I turn the beeping back on? I may have inadvertently changed some setting ( I hope)

 

The "beep" function can be set to on or off.
You can also adjust the volume of the sound.
Instructions are in your owner's manual which is available online as well.

Probably a YouTube video out there as well.

 

Thank you. I confirmed all my settings are set to have the car beep. I even reset them. But there is still no beep.

 

Sounds like the "beeper" or it's connection is bad.
I'm not certain but I believe the part is called a "warning buzzer" KD45676B1
