It's the little thing mate.Oh pass i have no idea
the car is pretty stock, according to my Audi app the only options i have are sat nav and bluetooth.
If i didn’t have a kid i would never of known, but they are very very handy.
when i got it i though the rear childlocks were broken as i couldn’t get them to work, read the manual and was mind blown that there was a button for them rather than the old manual key in door shut job
