Lincoln Aviator: Parking Aid - Vehicles With: Active Park Assist / Description and Operation - Parking Aid - Overview
Overview - Active Park Assist
The
active park assist system is a full-assisted parking system. The
system assists parking into and out (assist out of parking spots only
available for parallel parking) of parking spaces. Sensors are used to
detect parking spaces. The system then steers, accelerates, brakes and
shifts gears as required to maneuver into or out of a parking space.
The IPMB
uses input from the active park assist sensors, parking aid sensors and
a geometrical equation to determine whether the vehicle fits in the
parking space. If it is determined the vehicle will fit in the parking
space, the IPMB requests the correct steering angles from the PSCM and the correct vehicle speed from the PCM
during the parking maneuvers. The system visually and/or audibly
instructs the operator to park the vehicle through messages in the
centerstack infotainment display and audio system warning chimes.

NOTE:
No factory-equipped vehicle should have more than a 25 mA
(0.025 amp) – 50 mA (0.050) draw depending on the vehicle's accessories.
Check for current drains on the battery in excess of 25 mA (0.025 amp) –
50 mA (0.050) with all the electrical accessories off and the vehicle
at rest for at least 75 minutes (depending on region)...

Each door has a backup power system which
allows the door to function if your vehicle
has no power. The system has a limited
number of operations before the power is
depleted and turns off. When the system
turns off, the door remains open and
unlatched and does not close.
If your vehicle has no power and the backup
power system is turned off, you can close
and secure your vehicle by manually
resetting each door latch using a key in the
position shown.
