2019 Tucson Sport-No Beep from Rear Collision Warning?

Is the rear collision warning supposed to be an audible beep? I've nearly backed into several things because I was expecting to hear something. The brochure indicates the Sport trim level has this feature but I've heard nothing. I also don't have the "circles" on the rear bumper. Am I confusing two different features? Or does the Sport version not, in fact, offer this feature?

Thanks!

 

Call dealer up and question them.
They should be able to fix it

 

Hi,

I have the same issue. I have the Ultimate and no sensors in the bumper but I have a proximity warning feature in my rear view camera and I am not getting any warnings even when I am about to hit the car behind me. Attached is an image of the feature.

 

If your vehicle is 2019 then go back to the dealership to have them fix it
Or at least get the right answer.
