2023 LINCOLN AVIATOR service indicator

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.

Engine Emission Control

Note:When plugging into an unfamiliar wall
outlet, let the vehicle charge for several
minutes before leaving it unattended. The
red indicator will illuminate if not charging.
The unit will turn off if breaker or
infrastructure ground fault circuit interrupter
(GFCI) is tripped. You can view vehicle
charging status remotely via the Lincoln Way
App.
Mobile Power Cord Auto-Restart
Auto-restart helps to make sure that your
vehicle will be charged and ready for use
when needed. A charge could be interrupted
if errors are detected. Charging resumes
once the error is no longer detected. The
red indicator illuminates during an error
condition.
The exception to the immediate auto-restart
is when the interruption is due to a charger
ground fault circuit interrupter (GFCI) event.
The charger attempts to restart 15 minutes
after a ground fault circuit interrupter (GFCI)
event. After the fourth attempt to restart, the
charger shuts down and the red indicator
stays on.If the fault persists, do not continue to try to
charge your vehicle. Contact your authorized
dealer.
CARE INSTRUCTIONS
Do not use cleaners or solvents as this could
damage your mobile power cord. Do not
place stress on the charger cables. If unit
overheats, remove the mobile power cord
from direct sunlight.
SAFETY FEATURES
The charger includes the following safety
features to protect against the risk of electric
shock:
• Service Ground Check: The charger
constantly checks for the presence of a
service ground connection. If the service
ground ever fails, the charger red
indicator turns ON and shuts down power
to the vehicle.
• Thermal Event Sensor: Charger module
senses out-of-ordinary thermal events
and decreases the charging current or
shuts the unit down if required.• Ground fault circuit interrupter (GFCI)
Protection: The charger has a ground
fault circuit interrupter (GFCI) reaction
system to protect against electric shock.
If the charger module detects an output
ground fault, it shuts down power to the
output cable and illuminates the red
indicator.
• Insulation: The charger module,
connector, cable assembly, and charge
coupler are completely insulated. There
are no exposed live parts, to protect
against electric shock.
• Unintentional Disconnection: The charge
coupler is designed to minimize
unintentional disconnection. A pilot signal
wire in the cable and charge coupler
eliminates the possibility of electric shock
when not connected to a vehicle or if an
unintended disconnect occurs during a
charge. Disconnection during charging
is safe.

High Voltage Battery - Plug-In Hybrid Electric Vehicle (PHEV)

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.

Roadside Emergencies

WARNING: To reduce the risk of
serious injury, when mounting
replacement tires and wheels, you
should not exceed the maximum
pressure indicated on the sidewall of
the tire to set the beads without
additional precautions listed below. If
the beads do not seat at the maximum
pressure indicated, re-lubricate and
try again.
WARNING: For a mounting
pressure more than 20 psi (1.38 bar)
greater than the maximum pressure,
a Ford dealer or other tire service
professional should do the mounting.
WARNING: Always inflate steel
carcass tires with a remote air fill with
the person inflating standing at a
minimum of 12 ft (3.66 m) away from
the wheel and tire assembly.
WARNING: When inflating the
tire for mounting pressures up to
20 psi (1.38 bar) greater than the
maximum pressure on the tire sidewall,
the following precautions must be
taken to protect the person mounting
the tire:
• Make sure that you have the correct
tire and wheel size.
• Lubricate the tire bead and wheel
bead seat area again.
• Stand at a minimum of 12 ft (3.66 m)
away from the wheel and tire
assembly.
• Use both eye and ear protection.
Important: Remember to replace the
wheel valve stems when the road tires
are replaced on your vehicle.
It is recommended that the two front
tires or two rear tires generally be
replaced as a pair if the worn tires still
have usable depth.To avoid potential All Wheel Drive (AWD)
malfunction or All Wheel Drive (AWD)
system damage, it is recommended to
replace all four tires rather than mixing
significantly worn tires with new tires.
The tire pressure sensors mounted in
the wheels (originally installed on your
vehicle) are not designed to be used in
aftermarket wheels.
The use of wheels or tires not
recommended may affect the operation
of your tire pressure monitoring system.
If the tire pressure monitoring system
indicator is flashing, your system is
malfunctioning. Your replacement tire
might be incompatible with your tire
pressure monitoring system, or some
component of the system may be
damaged.

When Inflating Your Tires
WARNING: Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure to
follow this instruction could result in
personal injury or death.
When putting air into your tires (such as at a
gas station or in your garage), the tire
pressure monitoring system may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over
20 mph (32 km/h) for the light to turn off after
you have filled your tires to the
recommended inflation pressure.
How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system monitors
tire pressure in each pneumatic tire. While
driving in a normal manner, a typical
passenger tire inflation pressure may
increase about 2–4 psi (14–28 kPa) from a
cold start situation. If the vehicle is stationary
overnight with the outside temperaturesignificantly lower than the daytime
temperature, the tire pressure may decrease
about 3 psi (21 kPa) for a drop of 30°F (17°C)
in ambient temperature. This lower pressure
value may be detected by the tire pressure
monitoring system as being significantly
lower than the recommended inflation
pressure and activate the system warning
light for low tire pressure. If the low tire
pressure warning light is on, visually check
each tire to verify that no tire is flat. If one or
more tires are flat, repair as necessary.
Check the air pressure in the road tires. If
any tire is under-inflated, carefully drive the
vehicle to the nearest location where air can
be added to the tires. Inflate all the tires to
the recommended inflation pressure.
CHANGING A ROAD WHEEL
If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe place
on the side of the road.Have a flat serviced by an authorized dealer
in order to prevent damage to the tire
pressure monitoring system sensors. See
Tire Pressure Monitoring System (page 447).
Replace the spare tire with a road tire as
soon as possible. During repairing or
replacing of the flat tire, have the authorized
dealer inspect the tire pressure monitoring
system sensor for damage.
Note:You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note:The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.Dissimilar Spare Wheel and Tire

SYNC™ 3

When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 mi (800 km)
of the message appearing. Make sure you
reset the Intelligent Oil-Life Monitor after
each oil change. See Oil Change Indicator
Reset (page 402).
If your information display resets prematurely
or becomes inoperative, you should perform
the oil change interval at six months or
5,000 mi (8,000 km) from your last oil
change. Never exceed one year or 10,000 mi
(16,000 km) between oil change intervals,
Your vehicle is very sophisticated and built
with multiple, complex performance systems.
Every manufacturer develops these systems
using different specifications and
performance features. That is why it is
important to rely upon your dealership to
properly diagnose and repair your vehicle.We have recommended maintenance
intervals for various parts and component
systems based upon engineering testing.
We rely upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance schedules
that deviate from the scheduled maintenance
information.
We strongly recommend the use of only our
genuine manufactured or our authorized
re-manufactured replacement parts
engineered for your vehicle.
Additives and Chemicals
This owner's manual and our Workshop
Manual list the recommended additives and
chemicals for your vehicle. We do not
recommend using chemicals or additives not
approved by us as part of your vehicle’s
normal maintenance. Please consult your
warranty information.Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal
operating characteristic and, by itself, does
not necessarily indicate a concern or that the
fluid needs to be changed. However, a
qualified expert, such as the factory-trained
technicians at your dealership, should
inspect discolored fluids that also show signs
of overheating or foreign material
contamination immediately.
Make sure to change your vehicle’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle
sub-systems during scheduled maintenance.
It is critical that systems are flushed only with
new fluid that is the same as that required
to fill and operate the system or using our
approved flushing chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
