light LINCOLN AVIATOR 2023 Repair Manual

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.Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even AWD vehicles can lose traction
in slick mud. As when you are driving over
sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does
slide, steer in the direction of the slide until
you regain control of the vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance that could damage
drive components.“Tread Lightly” is an educational program
designed to increase public awareness of
land-use regulations and responsibilities in
our nations wilderness areas. Ford Motor
Company joins the U.S. Forest Service and

encouraging you to help preserve our
national forest and other public and private
lands by “treading lightly.”
Driving on Hilly or Sloping Terrain
Although natural obstacles could make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down.
Note: Avoid driving crosswise or turning on
steep slopes or hills. A danger lies in losing
traction, slipping sideways and possibly
rolling over. Whenever driving on a hill,
determine beforehand the route you will use.
Do not drive over the crest of a hill without
seeing what conditions are on the other side.
Do not drive in reverse over a hill without
the aid of an observer.

All-Wheel Drive (If Equipped)

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. Have your
vehicle checked. If your vehicle has
continuous vibration or shudder in the
steering wheel when braking, have your
vehicle checked.
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 427).
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. Move
the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle
checked. If your vehicle has to be towed,
we recommend that you contact a
professional towing service.
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.Note:Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
This lamp illuminates momentarily
when you switch the ignition on to
confirm the lamp is functional.
If the warning lamp does not illuminate
during start up, remains on or flashes, the
system may be disabled. Have the system
checked. If the anti-lock brake system is
disabled, normal braking is still operational.
See Warning Lamps and Indicators (page
131).
Note:Indicators vary depending on region.

Brakes

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
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system remembers
the last setting when you start your vehicle.
Vehicles with Automatic Transmission
You cannot turn the system on or off. When
you switch the ignition on, the system
automatically turns on.

WHAT IS REVERSE BRAKING
ASSIST
E205199E205199
Reverse braking assist is designed to reduce
impact damage or assist in avoiding a
collision while in reverse (R). Using sensors
on the rear of the vehicle, it can detect a
possible collision and apply the brakes. If full
braking occurs, the system attempts to stop
the vehicle a safe distance from the obstacle.
HOW DOES REVERSE BRAKING
ASSIST WORK
Reverse braking assist functions when in
reverse (R) and traveling at a speed of
1–7 mph (2–12 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,
fluorescent lamps, 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.
277
Reverse Braking Assist (If Equipped)

PRINCIPLE OF OPERATION
The traction control system helps avoid drive
wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces engine power at the
same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: Operating your vehicle
with the traction control disabled could
lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The system turns on each time you switch
on the ignition.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.Note:When you switch traction control off,
stability control remains fully active.
Switching the System Off
When you switch the system off or on, a
message appears in the information display
showing system status.
You can switch the system off by accessing
the traction control settings through the
touchscreen. See Settings (page 555).
Note:If your vehicle detects a loss of traction
due to excessive wheel spin or deceleration,
a display message appears on the
touchscreen prompting you to disable
traction control if needed.
Using the Information Display Controls
You can switch this feature off or on in the
information display. See General
Information (page 136).

Traction Control

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death.
WARNING: Remember that even
advanced technology cannot defy the laws
of physics. It’s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator’s
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death. If your
electronic stability control system activates,
SLOW DOWN.
The system automatically turns on each time
you switch the ignition on.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the systems applies higher
brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s ability
to prevent skids or lateral slides by applying
brakes to one or more of the wheels
individually and, if necessary, reducing
engine power.

Parking Aids

Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle’s regular brake system to prevent it
from overheating.
Note:An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.

When driving on a different line
than the vehicle in front. AB With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
There may be issues with the
detection of vehicles in front when
driving into and coming out of a
bend or curve in the road. C
In these cases, the system may brake late or
unexpectedly.
If something hits the front end of your vehicle
or damage occurs, the radar-sensing zone
may change. This could cause missed or
false vehicle detection.
