RCTA no warning sound

[paulpam]

Hi I have Cupra Ateca 2019 model when backing out of parking spaces the RCTA show cars approaching on the console display but no warning sound when image turns from orange to red .How is the sound warning system turned on. Sound works on rear parking senors when required.

If you go into settings, is there something in there to adjust the volume?
I am only having a guess as I have a setting in my Mondeo in there that I can adjust different volumes.
