System limitations
Parking Assist PARKTRONIC does not necessa‐
rily take into account the following obstacles:
Obstacles below the detection range, e.g.
R
persons, animals or objects.
Obstacles above the detection range, e.g.
R
overhanging loads, overhangs or loading
ramps of trucks.
The sensors must be free of dirt, ice and slush.
Otherwise, they may not function correctly.
Clean the sensors regularly, taking care not to
scratch or damage 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.
Passive side impact protection
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 to be detected,
the sensors in the front and rear bumper must
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 lateral segments light up
orange or red, depending on the distance to the
obstacle.
Color Lateral distance in cm
Red < 30
Orange 30 - 60
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 traveled the length of the vehicle, all
of the lateral front and rear segments can be dis‐
played.
