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.
485
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Scheduled Maintenance

At Every Oil Change Interval as Indicated by the Information Display
1
Inspect the steering linkage, ball joints, suspension and the tire-rod ends.
Inspect the tires, tire wear and measure the tread depth.
Inspect the wheels and related components for abnormal noise, wear, looseness or
drag.
1 Do not exceed one year or 12,500 mi (20,000 km) between service intervals.
2 Reset the Intelligent Oil-Life Monitor after engine oil and filter changes. See Engine Oil
Check
(page 326). Brake Fluid Maintenance
1
Change the brake fluid. 2
Every Three Years

to require a fluid change if the vehicle has
experienced extended periods of extreme
or severe duty cycle driving. Changing or
checking the transfer case, front and/or
rear axle lubricant is not necessary unless
the unit has been submerged in water,
shows signs of leakage, a message
indicating required service displays.
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.
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 5,000 mi (8,000 km).
If the available API SM or SN oils are not
available, then the oil change interval is
3,000 mi (4,800 km)
.
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.
