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 your
vehicle is used. 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.

Navigator (TB9) Canada/United States of America, enUSA, First-Printing Scheduled Maintenance

Off-road Operation
Rotate tires, inspect tires for wear and measure tread depth.
Change transfer case fluid (Four-wheel drive vehicles).
Every 60,000 mi
(96,000 km)
1 Reset your Intelligent Oil-Life Monitor after each engine oil and filter \
change.
Exceptions
There are several exceptions to the Normal
Schedule.
Axle and Transfer Case Maintenance
Axle(s) and transfer case (Four-wheel drive
vehicles) fluid changes or level checks are
not required unless a leak is suspected or
the assembly has been submerged in water.
Contact an 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. The Lincoln Motor Company,
however, urges you to have all
recommended maintenance services
performed at the specified intervals and to
record all vehicle service.Hot Climate Oil Change Intervals
Vehicles operating in the Middle East, North
Africa, Sub-Saharan Africa or locations with
similar climates using an American Petroleum
Institute (API) Certified for Gasoline Engines
(Certification mark) oil of SM or SN quality,
the normal oil change interval is
3,000 mi
(4,800 km).
If the available API SM or SN oils are not
available, then the oil change interval is
1,800 mi (2,900 km)
.
Engine Air Filter Replacement
The life of the engine 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.
