Lincoln Aviator: Hill Descent Control / What Is Hill Descent Control
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as ice
or extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of
vehicle control, crash or serious injury.
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake and shift the transmission into park
(P) for automatic transmission or first gear
for manual transmission.
Note: The system does not function below
3 mph (5 km/h).
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions.
The system can maintain vehicle speeds on
downhill slopes between 3–20 mph
(5–32 km/h). Above 20 mph (32 km/h), the
system remains on but the descent speed
cannot be set or maintained.
The system requires a cool down interval
after a period of sustained use. The amount
of time that the system can remain active
before cooling varies with conditions. The
system provides a warning in the message
center and a tone sounds when the system
is about to disengage for cooling. At this
time, manually apply the brakes as needed
to maintain descent speed.
Switching Hill Descent Control On and Off
You can switch the hill descent control on
and off through the touchscreen.
