Active Parking Assist no longer supports youwith steering interventions and brake applica-tions. When Active Parking Assist is finished,you must steer and brake again yourself. Park-ing Assist PARKTRONIC is still available.
Parking tips:
RThe way your vehicle is positioned in the park-ing space after parking is dependent on vari-ous factors. These include the position andshape of the vehicles parked in front andbehind it and the conditions of the location. Itmay be the case that Active Parking Assistguides you too far into a parking space, or notfar enough into it. In some cases, it may alsolead you across or onto the curb. If necessary,cancel the parking procedure with ActiveParking Assist.
RYou can also prematurely select transmissionposition[. The vehicle redirects and doesnot drive as far into the parking space. Shouldthe transmission change take place too early,the parking procedure is canceled. A sensibleparking position can no longer be achievedfrom this position.
Exiting a parking space
In order that Active Parking Assist can supportyou when exiting the parking space:
Rthe border of the parking space must be highenough at the front and the rear. A curb stoneis too small, for example.
Rthe border of the parking space must not betoo wide. Your vehicle can be maneuveredinto the parking space at a maximum angle of45° to the starting position.
Ra maneuvering distance of at least 3.3 ft(1.0 m) must be available.
Active Parking Assist can only assist you withexiting a parking space if you have parked thevehicle parallel to the direction of travel usingActive Parking Assist.
