bumper must /rst de tect the object while you are
driving past it.
During the parking procedure or manoeuvring,
objects are de tected as theve hicle drives past. If
yo u steer in the direction of a de tected obs tacle
and there is a risk of a lateral collision, a warning
is issued and the segments light up in colour in

Ac tive Parking Assist is an electronic parking
assistance system, which uses ultrasound with
th e assistance of there ve rsing camera and 360°
Camera. When you are driving forw ards up to
appr oximately 35 km/h, the system automatically
measures parking spaces on bo thsides of the
ve hicle.

th e Instrument Displa y.
When Active Parking Assist has de tected parking
spaces, theÈ display appears in the Instru-
ment Displa y.The ar rows show on which side of
th ero ad de tected parking spaces are located.
They are then shown in the media displa y.
The parking space can be selected as desired.
Depending on the location of the parking space,
th e parking direction (rear wards or forw ards) can
also be selected as desired.
When Active Parking Assist is activated, the turn
signal indicators are activated based on the calcu-
lated path of your vehicle.
When you are entering or exiting a parking space,
th e procedure is assisted byacceleration, braking,
steering and gear changes.
