steering LINCOLN NAVIGATOR 2015 Owner's Guide

WARNING:Obtain immediate service if a system error is
detected. You may not notice any difference in the feel of your
steering, but a serious condition may exist. Failure to do so may result
in loss of steering control.
Your vehicle is equipped with an electric power-assisted steering system.
There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Extreme continuous steering may increase the effort it takes
for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.
When a steering system error is detected, steering messages may appear
in the information display.
Steering Tips
If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

AUTO LEVELING SUSPENSION SYSTEM (if equipped)
The automatic leveling suspension system is designed to improve ride,
handling and general vehicle performance during:
•Certain road conditions
• Steering maneuvers
• Braking
• Acceleration
• Towing
This system keeps the rear of your vehicle at a constant level through a
hydraulic pump inside each rear shock. Depending on the payload or
road surface conditions it will take approximately 2 miles (3.2 km) for
the leveling to complete.
If the loaded vehicle is not moved for approximately 12 hours, the
leveling system may bleed down to a lower height. This can be especially
apparent if a trailer is left attached to the parked vehicle for long periods
of time. You must drive your vehicle in order to re-level the suspension.
If a self-equalizing hitch is being used, your vehicle should be drive
approximately 2 miles (3.2 km) with the trailer prior to adjusting
(leveling) the hitch.

•If your vehicle is equipped with Continuous Controlled Damping
Suspension (CCD Suspension), you can select NORMAL or SPORT
drive control modes for better experience while towing a trailer. See
the Information Displays chapter for details on selecting driving
modes.
• If you are towing a trailer frequently in hot weather, hilly conditions,
at the gross combined weight rating (or any combination of these
factors), consider refilling your rear axle with synthetic gear lubricant
(if the axle is not already filled with it). See the Capacities and
Specifications chapter for the lubricant specification.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in position P.
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not included with vehicle.)
Your vehicle may be equipped with a temporary or conventional spare
tire. A “temporary” spare tire is different in size (diameter or width),
tread-type (All-Season or All-Terrain) or is from a different manufacturer
than the road tires on your vehicle. Consult information on the tire label
or Safety Compliance label for limitations when using.
Launching or Retrieving a Boat or Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer beforebacking the trailer into
the water.
Note: Reconnect the wiring to the trailer afterremoving the trailer from
the water.
When backing down a ramp during boat launching or retrieval:
• Do not allow the static water level to rise above the bottom edge of
the rear bumper.
• Do not allow waves to break higher than 6 inches (15 centimeters)
above the bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
• Causing internal damage to the components.
• Affecting driveability, emissions, and reliability.
Replace the rear axle lubricant anytime the rear axle submerges in
water. Water may have contaminated the rear axle lubricant, which does
not normally require checking or changing unless it is leaking or other
axle repair is required.

TOWING THE VEHICLE ON FOUR WHEELS
Emergency Towing
WARNING:If your vehicle has a steering wheel lock, make sure
the ignition is in the accessory or on position when being towed.
If your vehicle becomes inoperable (without access to wheel dollies,
car-hauling trailer, or flatbed transport vehicle), it can be flat-towed (all
wheels on the ground, regardless of the powertrain and transmission
configuration) under the following conditions:
• Your vehicle is facing forward for towing in a forward direction.
• Place the transmission in position N.See Automatic transmission in
the Transmission chapter if you cannot move the transmission into
N.
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is 50 miles (80 kilometers).
Recreational Towing
Note: Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering your vehicle. See the Climate
Control chapter.
Follow these guidelines if you have a need for recreational towing, such
as towing your vehicle behind a motorhome. We designed these
guidelines to prevent damage to your transmission.
Do not tow your vehicle with any wheels on the ground, as vehicle or
transmission damage may occur. It is recommended to tow your vehicle
with all four (4) wheels off the ground, such as when using a car-hauling
trailer. Otherwise, you cannot tow your vehicle.

•Add particular accessories to your vehicle (e.g.; bug deflectors,
rollbars or light bars, running boards, ski racks).
• Drive with the wheels out of alignment.
DRIVING THROUGH WATER
WARNING: Do not drive through flowing or deep water as you
may lose control of your vehicle.
Note: Driving through standing water can cause vehicle damage.
Note: Engine damage can occur if water enters the air filter.
Before driving through standing water, check the depth. Never drive through water that is higher than the bottom
of the wheel hubs.
When driving through standing water, drive
very slowly and do not stop your vehicle. Your
brake performance and traction may be
limited. After driving through water and as
soon as it is safe to do so:
•Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that the steering power assist works.
FLOOR MATS
WARNING: Always use floor mats that are designed to fit the
foot well of your vehicle. Only use floor mats that leave the pedal
area unobstructed. Only use floor mats that are firmly secured to
retention posts so that they cannot slip out of position and interfere
with the pedals or impair safe operation of your vehicle in other ways.
WARNING: Pedals that cannot move freely can cause loss of
vehicle control and increase the risk of serious personal injury.

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.

When Fail-Safe Mode is Activated
WARNING:Fail-safe mode is for use during emergencies only.
Operate the vehicle in fail-safe mode only as long as necessary to
bring the vehicle to rest in a safe location and seek immediate repairs.
When in fail-safe mode, the vehicle will have limited power, will not be
able to maintain high-speed operation, and may completely shut down
without warning, potentially losing engine power, power steering assist,
and power brake assist, which may increase the possibility of a crash
resulting in serious injury.
WARNING: Never remove the coolant reservoir cap while the
engine is running or hot.
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Restart the engine and take your vehicle to an authorized dealer.
Note: Driving the vehicle without repairing the engine problem increases
the chance of engine damage. Take your vehicle to an authorized dealer
as soon as possible.
AUTOMATIC TRANSMISSION FLUID CHECK
Note: Transmission fluid should be checked by an authorized dealer. If
required, fluid should be added by an authorized dealer.
The automatic transmission does not have a transmission fluid dipstick.
Refer to your scheduled maintenance information for scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, (i.e., if the transmission slips or
shifts slowly) or if you notice some sign of fluid leakage.
Maintenance 271
2015 Navigator(nav)
Owners Guide gf, 2nd Printing, December 2014
USA (fus)

Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
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
Your vehicle is equipped with an electric power steering (EPS) system.
There is no fluid reservoir to check or fill. For additional information on
the electric power steering (EPS) system, Refer toDriving Aids.
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
the Capacities and Specifications chapter.
Note: The front and rear washer systems are supplied from the same
reservoir.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
