TRONIC does not detect such objects when
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and
objects which absorb ultrasonic sources.
Ultrasonic sources, such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill, could cause PARK-
TRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.

If there is an obstacle within this range, the
relevant warning displays light up and a warn-
ing tone sounds. If the distance falls below the minimum, the distance may no longer be
shown.
Warning displays The warning displays show the distance
between the sensors and the obstacle. The
