Limits of sensors and cameras
There are various sensors and cameras on the vehicle which detect and monitor the area around the vehicle by means
of ultrasound, radar waves and optical systems. The various parking systems use different combinations of the
sensors. Common to all sensors is the fact that they are subject to technical and physical limits →
.
—The sensors or cameras may not detect some objects, e.g. trailer drawbars, thin bars, fences, posts, trees, very low
or high obstacles, and boot lids that are open or being opened.
—The detection ranges of the sensors have blind spots in which obstacles and people are not registered.
—In some cases, dirt or ice and water on the sensors and cameras could be registered as an obstacle or impair
detection of objects. The sensor visibility may be impaired by dirt and snow or also residue from cleaning agents or
coatings.
—External sources of sound and certain surfaces on objects and clothing may influence the sensors’ signals. In
certain circumstances, the systems will be unable to detect or properly detect people and objects.
—It may be difficult or impossible to see objects such as narrow posts or railings on the screen because of its low
resolution or poor light conditions.
—The cameras show only two-dimensional images on the screen. The lack of depth of field means that potholes and
protruding objects on the ground may only be detected with difficulty, or may not be detected at all.
Practise using the parking systems in a traffic-calmed area or car park to familiarise yourself with the systems
and their functions.
Prerequisites
General information
The following prerequisites must be met so that the sensors and cameras are best able to detect the surroundings of
the vehicle and display this information on the Infotainment system:
✓ Doors and tailgate are closed.
✓ Exterior mirrors are not folded in.
✓ The sensors or cameras are not covered by add-on parts or trim frames for number plates.
✓ The surrounding area has a flat surface.
✓ Vehicle does not have a heavy load at the rear or on one side.
✓ Engine running.
✓ Brake support systems are switched on (→ Brake support systems).
The parking function and the acoustic warnings will be deactivated if other functions are operated on the
Infotainment system during a parking operation.
Finding a suitable parking space
Park Assist has system-related limitations. For example, Park Assist cannot help you to park the vehicle or drive out of
parking spaces if the vehicle is on a tight bend.
To ensure that a suitable parking space can be displayed and detected correctly, the following prerequisites must be
met:
✓ The length and width of the parking space must be larger than the vehicle dimensions and offer sufficient space
for manoeuvring.
✓ Distance when driving past the parking space: between 0.5 and 2 metres.
✓ Speed when driving past the parking space: maximum 40 km/h(25 mph).
