System limits of the ultrasonic  
sensors  
The detection of objects with ultrasonic meas-  
urements can run into physical limits, e.g., in  
the following situations:  
The ultrasonic sensors of the parking assis-  
tance systems are located in the front bumper.  
If the sensors are dirty or covered, e.g., by  
stickers.  
Ultrasonic sensors, rear  
If the sensor is not aligned correctly, for in-  
stance due to parking damage.  
After improper paint work on the vehicle in  
the area of the sensors.  
For small children and animals.  
For persons with certain clothing, for in-  
stance jacket.  
With obstacles and persons at the edge of  
the lane.  
In case of external interference with the  
ultrasonics, for instance from passing ve-  
hicles, loud machines or other ultrasonic  
sources.  
The ultrasonic sensors of the parking assis-  
tance systems are located in the rear bumper.  
Ultrasonic sensors, side  
Under certain weather conditions, e.g., high  
moisture, wet conditions, snowfall, cold, ex-  
treme heat, or strong wind.  
With tow bars and trailer hitches of other  
vehicles.  
With thin or wedge-shaped objects.  
With moving objects.  
With elevated, protruding objects such as  
ledges.  
With objects with corners, edges, and

In the case of objects with fine surfaces or  
structures, e.g., wire mesh fences.  
For objects with porous surfaces.  
With small and low objects, for instance  
boxes.  
Low objects already displayed, for instance  
curbs, can be outside of the detection  
ranges of the sensors.  
With soft obstacles or obstacles covered in  
foam material.  
With plants and bushes.  
In automatic car washes.  
In the event of uneven floors, e.g. speed  
bumps.  
If there are large amounts of exhaust gas.  
Cargo that extends beyond the perimeter of  
the vehicle is not taken into account by the  
ultrasonic sensors.  
If applicable, a Check Control message will be  
displayed when the system limits are reached.
