PARKTRONIC can suffer interference from:
R
ultrasonic sources such as a truck's
compressed-air brakes, an automatic car
wash or a pneumatic drill
R
attachments to the vehicle, e.g. rear
mounted racks
R
number plates (vehicle license plates)
that are not affixed flat against the
bumper
R
dirty or icy sensors
Remove a detachable trailer coupling if it is no
longer required. PARKTRONIC measures the
minimum detection range to an obstacle from
the bumper, not the ball coupling.
Range of the sensors
PARKTRONIC does not account for obstacles
that are:
R
beneath its detection range, e.g. persons,
animals or objects
R
above its detection range, e.g. overhanging
loads, overhangs or truck loading ramps
The sensors must be free of dirt, ice or slush.
Otherwise, they cannot function correctly.
Clean the sensors regularly, taking care not to
scratch or damage them (Y page 268).
Front sensors
Center Approx. 39 in
(100 cm)
Corners Approx. 26 in
(65 cm)
Rear sensors
Center Approx. 71 in
(180 cm)
Corners Approx. 39 in
(100 cm)
Minimum distance
Center Approx. 12 in
(30 cm)
Front corner sen-
sors
Approx. 10 in
(25 cm)
Rear corner sensors Approx. 12 in
(30 cm)
If an obstacle is within this range, all seg-
ments of the warning displays light up and you
hear a warning tone. If the distance between
the vehicle and the obstacle falls below the
minimum range, it is possible that the dis-
tance may no longer be displayed.
