General notes
Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both

a suitable parking space. Active steering inter-

during parking and when exiting a parking
space. You may also use PARKTRONIC

vehicle if necessary or cancel the Active Park-
ing Assist parking procedure.
