2023 LINCOLN AVIATOR tire pressure

Why is the feature not available (line markings are gray) when I can see the lane markings on the road?
You are driving too close to the vehicle in front of you.
Transitioning between no lane markings to lane markings or vice versa.
There is standing water on the road.
Faint lane markings, for example partial yellow lane markings on concrete roads.
Lane width is too narrow or too wide.
The camera has not been calibrated after a windshield replacement.
Driving on tight roads or on uneven roads.
Why does the vehicle not come back toward the middle of the lane, as expected, in the Aid or Aid and Alert mode?
High cross winds are present.
There is a large road crown.
Rough roads, grooves or shoulder drop-offs.
Heavy uneven loading of the vehicle or improper tire inflation pressure.
The tires have been changed, or the suspension has been modified.

Driving Aids

If your vehicle loses electrical power when
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can manually steer your
vehicle. Manually steering your vehicle
requires more effort.
Extreme continuous steering could increase
the effort you need to steer your vehicle. This
increased effort prevents overheating and
permanent damage to the steering system.
You do not lose the ability to manually steer
your vehicle. Typical steering and driving
maneuvers allow the system to cool and
operate as normal.
Steering Tips
If the steering wanders or pulls, check for:
• Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note:A high crown in the road or high
crosswinds could also make the steering
seem to wander or pull.Adaptive Learning
The electronic power steering system
adaptive learning improves overall handling
and steering on roads with irregularities. It
communicates with the brake system to help
operate advanced stability control and
accident avoidance systems. When you
install a new battery or disconnect the
battery, you need to drive your vehicle a
short distance so it can relearn and reactivate
all systems.
PRE-COLLISION ASSIST
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: The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
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: The system does not
operate during hard acceleration or
steering. Failure to take care may lead to
a crash or personal injury.
WARNING: The system may fail or
operate with reduced function during cold
and severe weather conditions. Snow, ice,
rain, spray and fog can adversely affect the
system. Keep the front camera and radar
free of snow and ice. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.

REDUCED ENGINE PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating. See Gauges (page
128).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to
prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See Engine
Coolant Check (page 404).
5. Have your vehicle checked as soon as
possible.
COLD WEATHER PRECAUTIONS
The functional operation of some
components and systems can be affected at
temperatures below approximately -13°F
(-25°C).
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuel
consumption:
• Drive smoothly, accelerate gently and
anticipate the road ahead to avoid heavy
braking.
• Regularly check your tire pressures and
make sure that they are inflated to the
correct pressure.
• Follow the recommended maintenance
schedule and carry out the
recommended checks.
• Plan your journey and check the traffic
before you set off. It is more efficient to
combine errands into a single trip
whenever possible.
• Avoid idling the engine in cold weather
or for extended periods. Start the engine
only when you are ready to set off.
• Do not carry unnecessary weight in your
vehicle as extra weight wastes fuel.

Driving Hints

Exterior Chrome Parts
• Apply a high quality-cleaning product to
bumpers and other chrome parts. Follow
the manufacturer’s instructions. We
recommend Motorcraft Custom Bright
Metal Cleaner.
• Do not apply the cleaning product to hot
surfaces. Do not leave the cleaning
product on chrome surfaces longer than
the time recommended.
• Using non-recommended cleaners can
result in severe and permanent cosmetic
damage.
Note:Never use abrasive materials, for
example steel wool or plastic pads as they
can scratch the chrome surface.
Note:Do not use chrome cleaner, metal
cleaner or polish on wheels or wheel covers.
Exterior Plastic Parts
For routine cleaning we recommend
Motorcraft Detail Wash. If tar or grease spots
are present, we recommend Motorcraft Bug
and Tar Remover.
Stripes or Graphics (If Equipped)
Hand washing your vehicle is preferred
however, pressure washing may be used
under the following conditions:
• Do not use water pressure higher than
2,000 psi (14,000 kPa).
• Do not use water hotter than 179°F (82°C).
• Use a spray with a 40 degree wide spray
angle pattern.
• Keep the nozzle at a 12 in (305 mm)
distance and 90 degree angle to your
vehicle's surface.
Note:Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
Underbody
Regularly clean the entire underside of your
vehicle. This includes the chassis, body floor
sheet metal and wheel wells using fresh
water. Keep body and door drain holes free
of debris or foreign material.
Under Hood
For removing black rubber marks from under
the hood we recommend Motorcraft Wheel
and Tire Cleaner or Motorcraft Bug and Tar
Remover.
WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your vehicle
in a shaded area out of direct sunlight.
Always wash your vehicle before applying
wax.
• Use a quality wax that does not contain
abrasives.
• Follow the manufacturer’s instructions to
apply and remove the wax.
• Apply a small amount of wax in a
back-and-forth motion, not in circles.
423
Vehicle Care

• Do not allow wax to come in contact with
any non-body (low-gloss black) colored
trim. The wax will discolor or stain the
parts over time.
• Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should feel
smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.When washing:
• Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold water
to avoid cracking the engine block or
other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine Shampoo.
Note:If your vehicle has an engine cover
remove the cover before application of
Motorcraft Engine Shampoo and Degreaser.
Immediately rinse away any over spray.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or the
area in and around these locations.
• Cover the battery, power distribution box,
and air filter assembly to prevent water
damage when cleaning the engine.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
• Clean the windshield with a non-abrasive
glass cleaner. When cleaning the interior
of the windshield, avoid getting any glass
cleaner on the instrument panel or door
panels. Wipe any glass cleaner off these
surfaces immediately.
• For windshields contaminated with tree
sap, chemicals, wax or bugs, clean the
entire windshield using steel wool (no
greater than 0000 grade) in a circular
motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.

Vehicle Care

Plugging in Your HYBRID
We recommend the following options for
your plug-in vehicle (PHEV) :
• Leave your vehicle plugged in. The 12
volt battery maintains power if left
plugged in. However, this periodically
uses electricity from the household
outlet.
• Connect a battery charger to your 12 volt
battery and leave it on a continuous, slow
charge.
• Disconnect the 12 volt battery. If your 12
volt battery is located in the luggage
compartment, do not fully shut the
luggage compartment after
disconnecting the 12 volt battery. Only
leave the luggage compartment open if
your vehicle is stored in a locked
location.
Brakes
• Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers and
pins under your vehicle are covered with
grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m) every
15 days to lubricate working parts and
prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt or
grease film build-up on window surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected during
storage such as mice or squirrel nests.
• Check the exhaust for any foreign
material that may have collected during
storage.• Check tire pressures and set tire inflation
per the Tire Label.
• Check brake pedal operation. Drive your
vehicle 15 ft (4.5 m) back and forth to
remove rust build-up.
• Check fluid levels (including coolant, oil
and gas) to make sure there are no leaks,
and fluids are at recommended levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.
Contact an authorized dealer if you have any
concerns or issues.
BODY STYLING KITS (IF EQUIPPED)
The distance between the underside of your
vehicle and the ground is less than that of
other models. Drive with extreme care to
avoid damage to your vehicle.

Vehicle Care

GENERAL INFORMATION
The recommended tire inflation pressures
are found on the Tire Label which is located
on the B-pillar or the edge of the driver door.
This information can also be found on the
Safety Compliance Certification Label, affixed
to either the door hinge pillar, door-latch
post, or the door edge that meets the
door-latch post; next to the driver’s seating
position.
We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the way
your vehicle handles.
Note:Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note:Check your tire pressures at least once
per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination.Use only approved wheels and tire sizes,
using other sizes could damage your vehicle.
If you change the diameter of the factory
installed tires, the speedometer may not
display the correct speed. This could effect
the functionality of the All Wheel Drive (AWD)
system, if equipped. Take your vehicle to an
authorized dealer and have the engine
management system reprogrammed.
If you intend to change the size of the factory
installed tires, check the suitability with an
authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found in the Wheels and Tire section.
See Tire Care (page 432).
Notice to utility vehicle and truck
owners
WARNING: Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
WARNING: In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seatbelt.
Utility vehicles and trucks handle differently
than passenger cars in the various driving
conditions that are encountered on streets,
highways and off-road. Utility vehicles and
trucks are not designed for cornering at
speeds as high as passenger cars any more
than low-slung sports cars are designed to
perform satisfactorily under off-road
conditions.

Wheels and Tires

The traction grades, from highest to
lowest are AA, A, B, and C. The grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature A B C
WARNING: The temperature
grade for this tire is established for a
tire that is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.
The temperature grades are A (the
highest), B and C, representing the tire’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can causethe material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
Glossary of Tire Terminology
*Tire label: A label showing the original
equipment tire sizes, recommended
inflation pressure and the maximum
weight the vehicle can carry.
*Tire Identification Number (TIN): A
number on the sidewall of each tire
providing information about the tire
brand and manufacturing plant, tire size
and date of manufacture. Also referred
to as DOT code.
*Inflation pressure: A measure of the
amount of air in a tire.*Standard load: A class of P-metric or
Metric tires designed to carry a
maximum load at set pressure. For
example: For P-metric tires 35 psi
(2.4 bar) and for Metric tires 36 psi
(2.5 bar). Increasing the inflation
pressure beyond this pressure will not
increase the tire’s load carrying
capability.
*Extra load: A class of P-metric or Metric
tires designed to carry a heavier
maximum load at 42 psi (2.9 bar).
Increasing the inflation pressure beyond
this pressure will not increase the tire’s
load carrying capability.
*kPa: Kilopascal, a metric unit of air
pressure.
*PSI: Pounds per square inch, a standard
unit of air pressure.
*Cold tire pressure: The tire pressure
when the vehicle has been stationary
and out of direct sunlight for an hour or
more and prior to the vehicle being
driven for 1 mi (1.6 km).
