2023 LINCOLN AVIATOR service

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.

Scheduled Maintenance

Multi-Point Inspection
Steering and linkage Exterior lamps operation
Tires (including spare) for wear and proper pressure
2Fluid levels1; fill if necessary
Windshield for cracks, chips or pits For oil and fluid leaks
Washer spray and wiper operation Half-shaft dust boots
1 Brake, coolant recovery reservoir, automatic transmission and window washer2If your vehicle is equipped with a temporary mobility kit, check the tire sealant expiration Use By date on the canister. Replace as needed.
Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive way
to perform a thorough inspection of your
vehicle. Your checklist gives you immediate
feedback on the overall condition of your
vehicle.
NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™
Your vehicle has an Intelligent Oil-Life
Monitor that determines when you should
change the engine oil based on how you use
your vehicle. By using several important
factors in its calculations, the monitor helps
reduce the cost of owning your vehicle and
reduces environmental waste at the same
time.This means you do not have to remember to
change the oil on a mileage-based schedule.
Your vehicle lets you know when an oil
change is due by displaying a message in
the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of use.

Scheduled Maintenance

lubricant will be more likely to require a
change if the vehicle has experienced
extended periods of extreme/severe duty
cycle driving. Changing or checking the PTU
lubricant is not necessary unless the unit has
been submerged in water, shows signs of
leakage or a message indicating required
service is displayed. Contact your authorized
dealer for service.
California fuel filter replacement: If you
register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. Ford Motor Company, however,
urges you to have all recommended
maintenance services performed at the
specified intervals and to record all vehicle
service.Engine air filter and cabin air filter
replacement: The life of the engine air filter
and cabin air filter is dependent on exposure
to dusty and dirty conditions. Vehicles
operated in these conditions require frequent
inspection and replacement of the engine
air filter and cabin air filter.
