2021 LINCOLN AVIATOR stop start

The cruise control indicator
replaces the adaptive cruise
control indicator if you select
normal cruise control. The gap setting does
not display, and the system does not respond
to lead vehicles. Automatic braking remains
active to maintain set speed. The system
remembers the last setting when you start
your vehicle.
SWITCHING LANE CENTERING ON
AND OFF
The cruise controls are on the steering
wheel. See Cruise Control (page 102). Press the button.
The indicator appears in the information
display. When the system is on, the color of
the indicator changes to indicate the system
status.
See Adaptive Cruise Control
Indicators (page 298).
Note: Adaptive cruise control must be on
before you can switch lane centering on. Activating Lane Centering
The system only activates when all of the
following occur:
•
You have adaptive cruise control with
stop-and-go on.
• Your hands are on the steering wheel.
• The system detects both lane markings.
Note: If it does not detect valid lane
markings, the system stays inactive until
valid markings are available.
You can override the system at any time by
steering your vehicle.
System Alerts and Automatic
Cancellation
You must keep your hands on the steering
wheel at all times.
When the system is active and detects no
steering activity for a certain period of time,
the system alerts you to put your hands on
the steering wheel. If you do not react to the
warnings the system cancels and slows your
vehicle down to idle speeds while
maintaining steering control. The system also alerts you if your vehicle
crosses lane markings without detected
steering activity.
Note:
The system may detect a light grip or
touch on the steering wheel as hands-off
driving.
When an external condition cancels the
system, for example, no lane markings
available, a tone sounds as the icon turns
amber then gray, and a message appears in
the information display.
Note: There are instances where the system
can cancel without displaying a message in
the information display. If your vehicle starts to slow down,
you must provide steering input to
the wheel and press and release
the button to regain full system performance.
Automatic cancellation can also occur if:
• The lane becomes too wide or too
narrow.
• The system cannot detect valid lane
markings.
• Lane markings are crossed.

Special Loading Instructions for
Owners of Pick-up Trucks and Utility-
type Vehicles
WARNING: When loading the
roof racks, we recommend you evenly
distribute the load, as well as maintain
a low center of gravity. Loaded
vehicles, with higher centers of gravity,
may handle differently than unloaded
vehicles. Take extra precautions, such
as slower speeds and increased
stopping distance, when driving a
heavily loaded vehicle.
AIR SUSPENSION
(IF EQUIPPED) WARNING:
If your vehicle has
self-leveling air suspension, you must
switch the system off before carrying out
any maintenance or repair. Failure to follow
this warning could result in serious
personal injury or death. The air suspension system automatically
adjusts to maintain a constant frame height,
allows for ease of vehicle loading, provides
improved vehicle ride, and increased driver
comfort.
You can adjust different ride settings through
the selectable drive modes.
See Selecting
a Drive Mode (page 329).
Note: The air suspension system may not
operate properly if you exceed the load limit.
See
Load Limit (page 334).
Note: When your vehicle is off, the air
compressor may run for a short time. This is
normal.
Switching the systems on or off
You can access the air suspension, liftgate
and easy entry features through the
information display menu settings.
See
General Information (page 134).
Using the Service Mode
When the service mode is active, the air
suspension does not make any adjustments
while your vehicle is stationary. Note:
Always switch the air suspension
service mode to on before servicing your
vehicle.
Using Cargo Loading
The air suspension cargo loading feature
lowers your vehicle for easier access when
the system detects the liftgate is opening.
When the liftgate is closed your vehicle
returns to its normal height after a short time.
Note: To preserve your vehicle battery, your
vehicle may only lower for cargo mode one
to two times per ignition cycle.
Using Easy Entry
The air suspension can lower your vehicle
to an easier access entry height when the
system detects the intelligent access key,
you press the unlock button, use the remote
start, or use Phone as a Key.
The leveling process stops when you open
a door or the target level is achieved.
Note: To stop the leveling process, press the
lock button on the intelligent access key.

Trailer Lamps
WARNING: Never connect any trailer
lamp wiring to the vehicle's tail lamp wiring;
this may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required.
Most towed vehicles require trailer lamps.
Make sure all running lights, brake lights,
direction indicators and hazard flashers are
working.
Before Towing a Trailer
Practice turning, stopping and backing up to
get the feel of your vehicle-trailer
combination before starting on a trip. When
turning, make wider turns so the trailer
wheels clear curbs and other obstacles. When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled
50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off automatically when you are
towing on long, steep grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective. •
If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and transmission
cooling.
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park
(P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not included
with vehicle.)

You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to stop your vehicle. You can
continue to drive.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1.
Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N). 2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.

Safety Practices
WARNING: If your vehicle is
stuck in snow, mud or sand, do not
rapidly spin the tires; spinning the tires
can tear the tire and cause an
explosion. A tire can explode in as little
as three to five seconds. WARNING:
Do not spin the
wheels at over 34 mph (55 km/h). The
tires may fail and injure a passenger
or bystander.
Driving habits have a great deal to do
with your tire mileage and safety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects on the road
*Do not run over curbs or hit the tire
against a curb when parking Highway Hazards
No matter how carefully you drive, there
is always the possibility that you may
eventually have a flat tire on the
highway. Drive slowly to the closest safe
area out of traffic. This may further
damage the flat tire, but your safety is
more important.
If you feel a sudden vibration or ride
disturbance while driving, or you suspect
your tire or vehicle has been damaged,
immediately reduce your speed. Drive
with caution until you can safely pull off
the road. Stop and inspect the tires for
damage. If a tire is under-inflated or
damaged, deflate it, remove wheel and
replace it with your spare tire and wheel.
If you cannot detect a cause, have the
vehicle towed to the nearest repair
facility or tire dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or pothole
can cause the front end of your vehicle
to become misaligned or cause damage
to your tires. If your vehicle seems to
pull to one side when you are driving,
the wheels may be out of alignment.
Have an authorized dealer check the
wheel alignment periodically.
Wheel misalignment in the front or the
rear can cause uneven and rapid
treadwear of your tires and should be
corrected by an authorized dealer.
Front-wheel drive vehicles and those
with an independent rear suspension (if
equipped) may require alignment of all
four wheels.
The tires should also be balanced
periodically. An unbalanced tire and
wheel assembly may result in irregular
tire wear.
