ignition LINCOLN AVIATOR 2021 Repair Manual

If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may not
have symptoms that are apparent, continued
driving with the service engine soon indicator
on can result in increased emissions, lower
fuel economy, reduced engine and
transmission smoothness and lead to more
costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs to
inspect the emission control equipment on
your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle
registration.
If the service engine soon indicator
is on or the bulb does not work,
your vehicle may need service.
See On-Board Diagnostics. Your vehicle may not pass the I/M test if the
service engine soon indicator is on or not
working properly (bulb is burned out), or if
the OBD-II system has determined that some
of the emission control systems have not
been properly checked. In this case, the
vehicle is not ready for I/M testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the vehicle
is not ready for I/M testing. To determine if
the vehicle is ready for I/M testing, turn the
ignition key to the on position for 15 seconds
without cranking the engine. If the service
engine soon indicator blinks eight times, it
means that the vehicle is not ready for I/M
testing; if the service engine soon indicator
stays on solid, it means that your vehicle is
ready for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing, you
can perform the following driving cycle
consisting of mixed city and highway driving: 1. 15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight
hours with the ignition off. Then, start the
vehicle and complete the above driving
cycle. The vehicle must warm up to its
normal operating temperature. Once
started, do not turn off the vehicle until
the above driving cycle is complete.
If the vehicle is still not ready for I/M testing,
you need to repeat the above driving cycle.

AUTOMATIC TRANSMISSION
WARNING: Always fully apply the
parking brake and make sure you shift into
park (P). Failure to follow this instruction
could result in personal injury or death. WARNING:
Do not apply the brake
pedal and accelerator pedal
simultaneously. Applying both pedals
simultaneously for more than a few
seconds will limit engine performance,
which may result in difficulty maintaining
speed in traffic and could lead to serious
injury.
Note: You cannot shift out of park (P) unless
the intelligent access key is inside your
vehicle.
Understanding Your Transmission
Selector Positions
Your vehicle has an electronic transmission
shifter. The transmission selector is on the
center stack below the touchscreen. Park.P
Reverse.
R
Neutral.
N
Drive.D
The instrument cluster displays the current
gear. Park (P)
With the transmission in park (P), your vehicle
locks the transmission and prevents the
wheels from turning. Always come to a
complete stop before putting your vehicle
into and out of park (P). An audible tone
sounds once you select park (P).
When you switch the ignition off, your vehicle
shifts into park (P). If you switch the ignition
off while your vehicle is moving, the
transmission first shifts into neutral (N) until
it reaches a speed less than 3 mph (5 km/h)
and then shifts into park (P).
The electric parking brake could apply when
you shift to park (P) without the brake pedal
fully pressed. The electric parking brake
applies when you shift to park (P) on large
slopes. The electric parking brake releases
with the drive away release function, or
manually as described in the Releasing the
Electric Parking Brake section.
See Electric
Parking Brake (page 258).
Note: A warning tone sounds if you open the
driver door and you have not shifted the
transmission selector to park (P).

With the transmission selector in reverse (R),
your vehicle moves backward. Always come
to a complete stop before shifting into and
out of reverse (R).
Neutral (N)
With the transmission selector in neutral (N),
you can start your vehicle and it is free to
roll. Hold the brake pedal down when in this
position.
Drive (D)
Drive (D) is the normal driving position for
the best fuel economy and smoothness. Shift
the transmission selector to drive (D) to allow
your vehicle to move forward and shift
through the forward gears.
The transmission shifts to the appropriate
gear for optimum performance based on
ambient temperature, road slope, vehicle
load and your input.
Automatic Return to Park
Note:
This feature does not operate when
your vehicle is in Stay in Neutral mode or
neutral tow.
The transmission returns to park (P) if any of
the following occur:
• You switch the ignition off.
• You do not have your seatbelt fastened
and you open the driver door.
• The driver door is open and you unfasten
your seatbelt.
If you switch the ignition off when your
vehicle is moving, your vehicle shifts into
neutral (N) until it slows down enough to shift
into park (P).
Note: This feature does not work properly if
the door ajar switch is malfunctioning. If your
door ajar indicator does not illuminate when
you open or close the driver door, or the
Transmission not in Park message still
displays in the information display when the
shifter has already selected (R), (N) or (D) and
the driver door remains closed, see your
authorized dealer. Stay in Neutral Mode
Note:
Stay in Neutral mode is a temporary
vehicle state that works with the engine in
a running or OFF state. Once in this mode,
maintain sufficient battery voltage, or your
vehicle returns to park (P) if left active for an
extended period of time when the engine is
off.
Failure to follow this instruction could result
in vehicle damage not covered by the vehicle
warranty.
Note: When entering an automatic car wash,
always enter the Stay in Neutral mode. Stay
in Neutral mode must be enabled if you are
exiting the vehicle before the car wash.
Extended usage of Stay in Neutral mode
could result in a battery voltage reduction to
a level where the vehicle no longer starts.

Manual Park Release
WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which means
your vehicle can roll freely. To avoid
unwanted vehicle movement, always fully
apply the parking brake prior to doing this
procedure. Use wheels chocks if
appropriate. WARNING:
If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. Have your vehicle
checked as soon as possible. WARNING: Do not drive your vehicle
until you verify that the stoplamps are
working.

Driving in Special Conditions With All-
Wheel Drive (AWD)
Note:
Use of the AWD system in slippery,
deep snow and sand drive modes on dry
surfaces could produce some vibration and
driveline bind up and, or excessive tire wear,
as the intent of these drive modes are for
slippery and loose surfaces.
Note: You can use AWD vehicles for driving
on sand, snow, mud and rough roads and
have operating characteristics that are
somewhat different from conventional
vehicles, both on and off the highway.
Basic Operating Principles in Special
Conditions
• Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice. If Your Vehicle Goes Off the Edge of the
Pavement
•
If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle back
onto the pavement only after reducing
your speed. Do not turn the steering
wheel too sharply while returning to the
road surface.
• It could be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You could lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often could be less risky to strike small
objects, such as highway reflectors, with
minor damage to your vehicle rather than
attempt a sudden return to the pavement
which could cause the vehicle to slide
sideways out of control or rollover.
Remember, your safety and the safety of
others should be your primary concern. If Your Vehicle Gets Stuck WARNING: Apply the parking brake,
shift into park (P), switch the ignition off
and remove the key before you leave your
vehicle. Failure to follow this instruction
could result in personal injury or death. WARNING: If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. Have your vehicle
checked as soon as possible. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow it
could be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.

Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing All-Wheel Drive
(If Equipped)

If your vehicle is equipped with
AdvanceTrac® with Roll Stability Control™, it
could be beneficial to disengage the
AdvanceTrac® with Roll Stability Control™
system while attempting to rock the vehicle.
Note:
Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission could occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the transmission
and tires could occur or the engine could
overheat.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid "over-driving"
your vehicle (i.e., turn the steering wheel
only as rapidly and as far as required to
avoid the emergency). Excessive steering
can result in less vehicle control, not
more. Additionally, smooth variations of
the accelerator and/or brake pedal
pressure should be utilized if changes in
vehicle speed are called for. Avoid abrupt steering, acceleration or braking which
could result in an increased risk of loss
of vehicle control, vehicle rollover and/or
personal injury. Use all available road
surface to return the vehicle to a safe
direction of travel.
• In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
• If the vehicle goes from one type of
surface to another (i.e., from concrete to
gravel) there is a change in the way the
vehicle responds to a maneuver
(steering, acceleration or braking). Again,
avoid these abrupt inputs.
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid spinning the wheels. Avoid excessive speed because vehicle
momentum can work against you and cause
the vehicle to become stuck to the point that
assistance could be required from another
vehicle. Remember, you could be able to
back out the way you came if you proceed
with caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability could be
limited.
Note:
Driving through deep water could
damage your vehicle.
When driving through water, determine the
depth; avoid water higher than the bottom
of the hubs (if possible) and proceed slowly.
If the ignition system gets wet, the vehicle
could stall.
Once through water, always try the brakes.
Wet brakes do not stop the vehicle as
effectively as dry brakes. Drying can be
improved by moving your vehicle slowly
while applying light pressure on the brake
pedal.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. Wet brakes result in reduced
braking efficiency. Gently press the brake
pedal a few times when driving from a car
wash or standing water to dry the brakes.
See Cleaning the Wheels (page 410). Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Switch
the engine off, move the transmission to park
(P) and apply the parking brake. Inspect the
accelerator pedal and the area around it for
any items or debris that may be obstructing
its movement. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist
can reduce stopping distances in critical
situations. Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. If the light does not momentarily
illuminate, continues to flash or
remains on when you switch the
ignition on or apply the parking brake, the
anti-lock braking system could be disabled.
Have the system checked by an authorized
dealer. If the anti-lock brake system is
disabled, normal braking is still effective.
See
Warning Lamps and Indicators (page
129).
Note: Indicators vary depending on region. If the light does not momentarily
illuminate, continues to flash or
remains on when you switch the
ignition on or apply the parking
brake, have the system checked
by an authorized dealer. If the
brake warning lamp illuminates with the
parking brake released, have the system
checked immediately.

HINTS ON DRIVING WITH ANTI-
LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
ELECTRIC PARKING BRAKE WARNING: Always fully apply the
parking brake and make sure you shift into
park (P). Failure to follow this instruction
