Lincoln Aviator: Pre-Collision Assist / Using the Pre-Collision Assist System
The system is active at speeds above
approximately 3 mph (5 km/h) and pedestrian
detection is active at speeds up to 50 mph
(80 km/h).

If your vehicle is rapidly approaching another
stationary vehicle, a vehicle traveling in the
same direction as yours, or a pedestrian
within your driving path, the system is
designed to provide three levels of
functionality:
- Alert
- Brake Support
- Active Braking

Alert: When active, a flashing visual warning
appears and an audible warning tone
sounds.
Brake Support: The system is designed to
help reduce the impact speed by preparing
the brakes for rapid braking. Brake support
does not automatically apply the brakes. If
you press the brake pedal, the system could
apply additional braking up to maximum
braking force, even if you lightly press the
brake pedal.
Active Braking: Active braking may activate
if the system determines that a collision is
imminent. The system may help the driver
reduce impact damage or avoid the crash
completely.
Note: Brake Support and Active Braking are
active at speeds up to 75 mph (120 km/h). If
your vehicle has a radar sensor included
with Adaptive Cruise Control, then Brake
Support and Active Braking are active up to
the maximum speed of the vehicle.
Note: If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends using
the highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings.
Note: Pre-Collision Assist turns off when you
select deep conditions or deep sand mode.
WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention...
Distance Indication and Alert is a function
that provides the driver with a graphical
indication of the time gap to other preceding
vehicles traveling in the same direction...
