Front sensors

Rear sensors

When parking, pay particular attention to objects above or below the sensors, such as flower pots or trailer drawbars.
PARKTRONIC 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 other objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car wash, the compressed-air brakes on a truck or a pneumatic drill could cause PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on uneven terrain.
Minimum distance

If there is an obstacle within this range, the relevant warning displays light up and a warning tone sounds. If the distance falls below the minimum, the distance may no longer be shown.
