Obstacles above the detection range, e.g.
R
overhanging loads, overhangs or loading
ramps of lorries.

age them.
Vehicles with trailer hitch: Parking Assist
PARKTRONIC is deactivated for the rear zone
when you establish an electrical connection
between your vehicle and a trailer.
Function of the passive side impact protec‐
tion
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 manoeuvring,
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
to the obstacle.
Segment colour depending on distance
Colour Lateral distance in
cm
Yellow Approx. 30 - 60
Red Approx. < 30
In order for lateral front or rear segments to be
displayed, the vehicle must first travel a distance
of at least half of the vehicle length. Once the
vehicle has travelled the length of the vehicle, all
of the lateral front and rear segments can be dis‐
played.
