!
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objects when
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill could cause PARK-
TRONIC to malfunction.
Minimum distance
Centre approximately 20 cm
Corners approximately 15 cm
If there is an obstacle within this range, all
warning displays light up and a warning tone
sounds. If the distance falls below the mini-
mum, the distance may no longer be shown.
Warning displays
The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located
on the dashboard above the centre air vents.
The warning display for the rear area in the
Coupé is located on the roof lining in the rear
compartment; in the Cabriolet, it is between
the rear seats.
