Exclusive Parking Assist
Ultrasonic sensors
On vehicles with Exclusive Parking Assist, the outer
left and right front ultrasonic sensors are not just used
for the PARKTRONIC function, they also scan the road
for potential parallel parking spaces. The two outer
sensors therefore change their sensing range.
• Range of parking space search
• Range of PARKTRONIC function

Function sequence
The parking space search function does not have to be
activated. At vehicle speeds of up to 36 km/h, the
outer ultrasonic sensors in the front bumper continu-
ously measure the parking spaces. The parking spaces
are stored for a distance of approx. 15 m.
The multifunction display in the instrument cluster
displays the symbol "P" to indicate that it is searching
for parking spaces. When a parking space is found, an
arrow indicates the side of the road on which the
parking space is located.
i Note
By default the system only indicates parking
spaces on the passenger-side of the vehicle. To
have parking spaces on the driver side indicated
as well (e.g. on one-way streets), the driver must
actuate the turn signal towards the driver side.
The parking space search function detects parallel
parking spaces based on the following criteria:
The space must be parallel to the road, must be at
least 1.3 m longer than the vehicle, may not be longer
than 10 m and must be at least 1.5 m wide.
