2021 LINCOLN AVIATOR park assist

HILL START ASSIST
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake. WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
The system will turn off
if a malfunction is apparent or if you rev
the engine excessively. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake. When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal. The
system releases the brakes automatically
once the engine has developed sufficient
torque to prevent your vehicle from rolling
down the slope. This is an advantage when
pulling away on a slope, for example from a
car park ramp, traffic lights or when reversing
uphill into a parking space.
The system activates on any slope that
causes your vehicle to roll.
Note:
There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep the
brake pedal pressed and shift into first
gear when facing uphill or reverse (R)
when facing downhill.
2. If the sensors detect that your vehicle is on a slope, the system activates
automatically. 3. When you remove your foot from the
brake pedal, your vehicle remains on the
slope without rolling away for about two
to three seconds. This hold time
automatically extends if you are in the
process of driving off.
4. Drive off in the normal manner. The system releases the brakes automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off

WHAT IS REVERSE BRAKING
ASSIST
The system is designed to reduce impact
damage or avoid a collision completely by
using the sensors on the rear of your vehicle.
The system functions when in reverse (R)
and traveling at a speed of 1–7 mph
(1.5–12 km/h).
If the system detects an obstacle behind your
vehicle, it provides a warning through the
rear parking aid or cross traffic alert system. REVERSE BRAKING ASSIST
PRECAUTIONS 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. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING:
Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system. This may
cause reduced performance or false alerts. WARNING:
Some situations and
objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types, and
pedestrians. Apply the brakes when
necessary. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not use the system
with accessories that extend beyond the
front or rear of your vehicle, for example a
trailer hitch or bike rack. The system is not
able to make corrections for the additional
length of the accessories.
The system only applies the brakes for a
short period of time when an event occurs.
Act as soon as you notice the brakes apply
in order to remain in control of the vehicle.

Note:
Certain add-on devices around the
bumper or fascia may create false alerts. For
example, large trailer hitches, bicycle or
surfboard racks, license plate brackets,
bumper covers or any other device that may
block the normal detection zone of the
system. Remove the add-on device to
prevent false alerts.
Note: The system does not react to small or
moving objects, particularly those close to
the ground.
Note: The system does not operate during
hard acceleration or steering.
Note: If your vehicle sustains damage to the
bumper or fascia leaving it misaligned or
bent, it could alter the sensing zone causing
inaccurate measurement of obstacles or
false alerts. Note:
Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.
Note: When you connect a trailer, the system
may detect the trailer and provide an alert,
or the system turns off. If the system does
not turn off, switch the system off manually
after you connect the trailer.
Note: You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.
SWITCHING REVERSE BRAKING
ASSIST ON AND OFF
You can switch the system on or off through
the touchscreen. See Settings (page 540). Note:
The system is unavailable when rear
parking aid or cross traffic alert is off.
OVERRIDING REVERSE BRAKING
ASSIST
There could be instances when unexpected
or unwanted braking occurs. Firmly pressing
the accelerator pedal or switching the feature
off overrides the system.
REVERSE BRAKING ASSIST
INDICATORS
If the system determines that a collision with
an obstacle may occur, full braking may
apply. Bring your vehicle to a stop a safe
distance away from the obstacle. A message and warning indicator
appear when the system applies
the brakes.

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. SETTING THE HILL DESCENT
SPEED 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. WARNING:
The system does not
control speed in low traction conditions or
extremely steep slopes. The system is
designed to be an aid and does not relieve
you of your responsibility to drive with due
care and attention. Failure to follow this
instruction could result in personal injury.
To increase the descent speed, press the
accelerator pedal until you reach the speed
you prefer.
To decrease the descent speed, press the
brake pedal until you reach the speed you
prefer.

WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The parking aid system
can only assist you to detect objects when
your vehicle is moving at parking speeds.
To help avoid personal injury you must
take care when using the parking aid
system.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this may
cause inaccurate measurements or false
alerts.
Note: Some accessories, for example large
trailer hitches or bike or surfboard racks can
cause reduced performance or false alerts.
The sensors are on the rear bumper. The sensors are active when the
transmission is in reverse (R) and the vehicle
speed is less than 3 mph (5 km/h). When the
parking aid system sounds a tone, the audio
system may reduce the set volume.
A warning tone sounds when your vehicle
approaches an object. As your vehicle
moves closer to an object, the rate of the
tone increases. The warning tone
continuously sounds when an object is 12 in
(30 cm)
or less from the center of the rear
bumper.
Note: There is a decreased coverage area
at the outer corners. The sensor coverage area is up to
70 in
(180 cm) from the rear bumper.
If the system detects a fault, a warning
message appears in the information display.
