maintenance LINCOLN NAVIGATOR 2017 Workshop Manual

Your vehicle is equipped with the Intelligent
Oil-Life Monitor system, which displays a
message in the information display at the
proper oil change interval. This interval may
be up to one year or 10000 miles (16000
kilometers).
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 miles (800
kilometers) of the message appearing. Make
sure you reset the Intelligent Oil-Life Monitor
after each oil change. See Oil Change
Indicator Reset (page 267).
If your information display resets prematurely
or becomes inoperative, you should perform
the oil change interval at six months or 5000
miles (8000 kilometers) from your last oil
change. Never exceed one year or 10000
miles (16000 kilometers) 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.
Ford Motor Company has recommended
maintenance intervals for various parts and
component systems based upon engineering
testing. Ford Motor Company relies 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
genuine Ford, Motorcraft or Ford-authorized
re-manufactured replacement parts
engineered for your vehicle.Additives and Chemicals
This owner's manual and the Ford 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.

Navigator (TB5) Canada/United States of America, enUSA, First Printing Scheduled Maintenance

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 a
Ford-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. Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level. Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if necessary. Parking brake for proper operation.
458

Check every six months
Safety belts and seat latches for wear and function.
Safety warning lamps (brake, ABS, airbag and safety belt) for operation.
Washer spray and wiper operation. Clean or replace blades as necessary.
Multi-Point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval to
help make sure your vehicle keeps running
great. Multi-Point inspection
Hazard warning system operation
Accessory drive belt(s)
Horn operation
Battery performance
Radiator, cooler, heater and air conditioning hoses
Engine air filter
Suspension components for leaks or damage
Exhaust system

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 is equipped with 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.
