Parking sensors:
normal, they go off above a certain speed, you can code this lower/higher if you want.
Its useful if you a parking and just need to do a small correction by going forward, in a tight spot you don't have to manually enable it again.
Lights:
They stay on for 2 minutes, I guess to avoid on/off, on/off to frequently.
btw. you should find such information also in the manual
