STEERING
Electric Power Steering
WARNING: The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked as soon as possible. WARNING:
If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control.
Your vehicle has an electric power steering
system, there is no fluid reservoir, no
maintenance is required. If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle, this increased effort prevents
overheating and permanent damage to the
steering system. You do not lose the ability
to steer your vehicle manually. Typical
steering and driving maneuvers allow the
system to cool and return to normal
operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment. Note:
A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
(If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with the
brake system to help operate advanced
stability control and accident avoidance
systems. Additionally, whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short distance
before the system relearns the strategy and
reactivates all systems.

Note:
If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor automatically recalibrates
successfully.
DRIVE MODE CONTROL
Lincoln Drive Modes
Lincoln Drive Modes deliver a driving
experience through a suite of sophisticated
electronic vehicle systems. These systems
optimize steering, handling and powertrain
response. You can control performance
settings for multiple systems from this single
location.
Changing the drive mode automatically
changes the functionality of the following
systems: •
Electronically power-assisted steering
system adjusts steering effort and feel
based on the mode you select. See
Steering (page 297).
• Electronic stability control and traction
control maintain your vehicle control in
adverse conditions or high performance
driving. See Stability Control (page 248).
• Electronic throttle control enhances the
powertrain response to your inputs.
• Transmission controls optimize with shift
schedules tuned to each mode.
• Driveline settings optimize for each
mode.
Using the System
The system automatically tailors your vehicle
configuration for each mode you select. To change the drive mode setting, use the
drive mode selector on the center console.
Note:
Mode changes are not available when
the vehicle ignition is off or when the engine
is not running.
Note: Not all settings may be available.

•
NORMAL – For everyday driving. This
mode is a perfect balance of excitement,
comfort and convenience.
• EXCITE – For aggressive on-road driving.
This mode increases throttle response,
provides a sportier steering feel, along
with quicker shifting. The suspension
stiffens, with an emphasis on handling
and control. The transmission also holds
gears longer, helping your vehicle
accelerate faster when shifting gears.
• CONSERVE
– Enables efficient and
responsible driving. It helps deliver
maximum fuel efficiency and increases
driving range.
• NORMAL 4A
– For general on-road
driving. Use this mode on normal firm
surfaces such as dry or wet pavement
and hard packed dirt or gravel roads.
Delivers power to all four wheels, as
required. •
SLIPPERY
– For less than ideal road
conditions, such as snow or ice covered
roads. Slippery mode inspires confidence
without taking away from driving
pleasure. Slippery mode lowers throttle
response and optimizes shifting for
slippery surfaces.
• DEEP CONDITIONS
– Used for crossing
terrain that has deformable deep, rutted
surfaces such as mud, deep snow or
deep sand. Do not use on dry, hard
surfaced roads.
• SLOW CLIMB
– Used when you need
extra power, such as when climbing
steep grades, going through deep sand
or pulling a boat out of a launch ramp.
Do not use on dry, hard surfaced roads.
Slow Climb mode puts you in 4x4 Low
drive line settings.
Note: Slow Climb is only available on
vehicles with 4x4 and a two-speed transfer
case. Note:
The system has diagnostic checks that
continuously monitor the system for proper
operation. Certain drive modes are not
available based on gear shifter position. If
a mode is unavailable due to a system fault
or change in gear shifter position, the mode
defaults to
NORMAL.

•
Do not rest your foot on the brake pedal
while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment.
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics.
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:
Use a floor mat designed
to fit the footwell of your vehicle that does
not obstruct the pedal area. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
Pedals that cannot move
freely can cause loss of vehicle control and
increase the risk of serious personal injury.

Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
440).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display. If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked 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 your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, your 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:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.

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

Note:
If the brake fluid level is below the MIN
mark or above the MAX mark, have your
vehicle checked as soon as possible.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our specifications.
See
Capacities and Specifications (page
440).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Change the brake fluid at the specified
intervals to prevent degraded braking
performance.
For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill. CHANGING THE 12V BATTERY WARNING:
Batteries normally
produce explosive gases which can cause
personal injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in personal
injury and damage to the vehicle or battery.
Lift the battery with a battery carrier or with
your hands on opposite corners. WARNING:
Keep batteries out of
reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush immediately
with water for a minimum of 15 minutes and
get prompt medical attention. If acid is
swallowed, call a physician immediately. WARNING:
Battery posts, terminals
and related accessories contain lead and
lead compounds, chemicals known to the
State of California to cause cancer and
reproductive harm. Wash your hands after
handling
.

Note:
Your vehicle may be equipped
with a dissimilar spare wheel and tire
assembly. A dissimilar spare wheel and
tire assembly is defined as a spare
wheel and tire assembly that is different
in brand, size or appearance from the
road tires and wheels. If you have a
dissimilar spare wheel and tire assembly
it is intended for temporary use only and
should not be used in a tire rotation.
Note: After having your tires rotated,
inflation pressure must be checked and
adjusted to the vehicle requirements.
Rotating your tires at the recommended
interval (as indicated in the Scheduled
Maintenance chapter) will help your tires
wear more evenly, providing better tire
performance and longer tire life.
Rear-wheel drive vehicles and
four-wheel drive vehicles (front tires at
left of diagram) Sometimes irregular tire wear can be
corrected by rotating the tires.
USING SNOW CHAINS
WARNING: Snow tires must be the
same size, load index and speed rating as
those originally provided by Ford. Use of
any tire or wheel not recommended by
Ford can affect the safety and performance
of your vehicle, which could result in an
increased risk of loss of control, vehicle
rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels can cause steering,
suspension, axle, transfer case or power
transfer unit failure. Follow the Ford
recommended tire inflation pressure found
on the Safety Compliance Certification
Label (on the door hinge pillar, door latch
post or the door edge that meets the door
latch post, next to the driver seat), or Tire
Label on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and adversely
affect the way your vehicle handles.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need to
use cables, it is recommended that steel
wheels (of the same size and specifications)
be used, as cables may chip aluminum
wheels.
