service indicator LINCOLN NAVIGATOR 2013 User Guide

If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
corrosion/freeze protection characteristics of the engine coolant and
may cause engine damage.
Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.
What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine coolant temperature gauge
will move to the red (hot) area and:
The coolant temperature warning light will illuminate.
The service engine soon indicator will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be restarted. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.

BRAKE FLUID CHECK
Fluid levels between the MIN and MAX lines are within the normal
operating range; there is no need to add fluid. If the fluid levels are outside
of the normal operating range, the performance of the system could be
compromised; seek service from your authorized dealer immediately.
POWER STEERING FLUID CHECK
Check the power steering fluid. Refer toscheduled maintenance
information.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir. Refer to theCapacities and
Specificationschapter for the proper fluid type.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter that is integrated with
the fuel tank. Regular maintenance or replacement is not needed.
WASHER FLUID CHECK
WARNING:If you operate your vehicle in temperatures below
40°F (5°C), use washer fluid with antifreeze protection. Failure
to use washer fluid with antifreeze protection in cold weather could
result in impaired windshield vision and increase the risk of injury or
accident.
Add fluid to fill the reservoir if the level is low. Only use a washer fluid
that meets Ford specifications. See the technical specifications chart in
theCapacities and Specificationschapter.
Note:The front and rear washer systems are supplied from the same
reservoir.

CHANGING A ROAD WHEEL
WARNING:The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used.
However, if you must use a sealant, the TPMS sensor and valve stem on
the wheel must be replaced by an authorized Ford dealer.
WARNING:SeeTire Pressure Monitoring Systemin this
chapter for important information. If the tire pressure monitor
sensor becomes damaged, it will no longer function.
Note:The tire pressure monitoring system indicator light will illuminate
when the spare tire is in use. To restore the full functionality of the
monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
If you get a flat tire while 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 TPMS sensors. SeeTire Pressure Monitoring Systemearlier in
the chapter. 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 TPMS sensor for damage.
Dissimilar Spare Tire and Wheel Assembly Information
WARNING:Failure to follow these guidelines could result in an
increased risk of loss of vehicle control, injury or death.
If you have a dissimilar spare tire and wheel assembly, then it is intended
for temporary use only. This means that if you need to use it, you should
replace it as soon as possible with a road tire and wheel assembly that is
the same size and type as the road tires and wheels that were originally
provided by Ford. If the dissimilar spare tire or wheel is damaged, it
should be replaced rather than repaired.
A dissimilar spare tire and wheel assembly is defined as a spare tire or
wheel that is different in brand, size or appearance from the road tires
and wheels and can be one of three types:
1.T-type mini-spare:This spare tire begins with the letter T for tire
size and may have Temporary Use Only molded in the sidewall.
