Function of the passive side impact protec‐

Passive side impact protection is an additional
Parking Assist PARKTRONIC function which
warns the driver about obstacles at the side of
the vehicle. A warning is issued when obstacles
are detected between the front and rear detec‐
tion range. In order for an object on the side to
be detected, the sensors in the front and rear
bumper must first detect the object while you
are driving past it.
During the parking procedure or maneuvering,
objects are detected as the vehicle drives past.
If you steer in the direction of a detected obsta‐
cle and there is a risk of a lateral collision, a
warning is issued. The segments on the sides
light up yellow or red, depending on the distance
