Parking sensors sensitivity

[CB72]

Is there a way of reducing the sensitivity of the parking sensors, when they are displaying full bars there is still plenty room to walk in front of car. Also when parking in a tight space the corner sensors are on full bars so you can't tell how much room you have, and when you check there is bags of room! So basically it's just  a warning  to be careful.

Page 486 of the english MY24 manual lists the distances for the different indicators:
Red (continuous beep) starts already at about 35 cm space left which confirms your findings.
The manual doesn't mention any possibility of changing the sensitivity though.
