No audible beep from rear sensors when backing

[maxum3300]

I just bought a 2021 Silverado 2500HD. When I'm backing and get close to objects I get a caution symbol that flashes up on the screen but no audible beeping. I looked in the manual and it says in the settings under collision/detection system the following may appear:

Alert Type

Forward Collision system

Lane Change Alert

Park Assist

Rear camera park assist symbols

Rear cross traffic alert.

 

The manual goes on to say that alert type sets the alert from either beeps or safety alert seat. When I go into my menu under collision/detection system I dont have options for Alert Type or Forward Collision system but i have the other options lane change alert and so on.

 

Am I to assume that because I don't have alert type in my settings menu I have no audible warning? Seems odd that it would have a rear backup detection system that shows visual warning symbols on the screen but no audible beeps. Even my 2019 work truck beeps when I get close to something while backing up. If I don't have the audible warning is there a way to add it?

Did you figure anything out?

My '21 only had the seat vibrate as far as I can remember.  I missed the audible beep but don't think there was a way to change it.  Still better than my '22, has all the sensors and button but still missing the module to make it work .
