18.7.3.￿Deactivation￿criteria
Manual￿deactivation￿criteria
The￿Parking￿Maneuver￿Assistant￿PMA￿can￿be￿deactivated￿at￿any￿time￿if￿necessary￿by￿the￿driver￿via
the￿controller￿by￿selecting￿the￿corresponding￿symbol￿in￿the￿symbol￿bar￿on￿the￿Central￿Information
Display￿CID.￿Another￿way￿to￿deactivate￿the￿Parking￿Maneuver￿Assistant￿PMA￿is￿to￿release￿the￿parking
assistance￿button￿in￿the￿switch￿block￿next￿to￿the￿iDrive￿controller.
If￿a￿fault￿develops,￿a￿Check￿Control￿message￿("The￿PDC￿has￿malfunctioned.￿Have￿system￿checked.")￿is
displayed￿in￿the￿Central￿Information￿Display￿CID.
Automatic￿deactivation￿criteria
The￿Parking￿Maneuver￿Assistant￿PMA￿is￿switched￿off￿automatically￿when￿the￿following￿events￿occur:
• the￿parking￿assistance￿button￿is￿released
• the￿driver￿holds￿on￿to￿the￿steering￿wheel￿or￿steers￿himself
• a￿gear￿is￿selected￿that￿does￿not￿correspond￿to￿the￿instruction￿on￿the￿control￿display
• when￿accelerating
• the￿parking￿brake￿is￿secured
• the￿turn￿indicator￿opposite￿the￿required￿parking￿side￿is￿switched￿on
• at￿speeds￿above￿about￿10 km/h
• possibly￿if￿the￿roadway￿is￿covered￿with￿snow￿or￿is￿slippery
• the￿tailgate￿is￿open
• possibly￿if￿the￿objects￿are￿difficult￿to￿overcome,￿e.g.￿curbs
• if￿obstructions￿suddenly￿appear
• a￿maximum￿number￿of￿parking￿maneuvers￿or￿the￿parking￿duration￿has￿been￿exceeded.
18.8.￿Limits￿of￿the￿system
The￿detection￿of￿objects￿can￿test￿the￿ultrasonic￿measurement￿system￿to￿its￿limits.￿Several￿examples￿of
this￿are￿shown￿below:
• with￿trailer￿towbars￿and￿couplings
• if￿the￿objects￿are￿thin￿or￿wedge-shaped
• if￿the￿objects￿are￿projecting￿and￿elevated,￿e.g.￿wall￿projections￿or￿loads
• if￿the￿objects￿have￿corners￿and￿sharp￿edges
• if￿the￿objects￿have￿fine￿surfaces￿or￿structures,￿e.g.￿fences.
Low￿objects￿that￿are￿already￿displayed,￿e.g.￿curbs,￿may￿fall￿within￿the￿blind￿spot￿of￿the￿sensors￿before
or￿after￿a￿continuous￿alarm￿sounds.￿It￿would￿not￿be￿possible￿to￿detect￿objects￿that￿are￿higher￿up￿and
projecting,￿e.g.￿wall￿projections.￿Parking￿spaces￿may￿be￿detected￿although￿these￿are￿not￿suitable.
