2015 LINCOLN NAVIGATOR warning

In order to prevent the engine from running at too low an RPM, which
may cause it to stall, the SST will still automatically make some
downshifts if it has determined that you have not downshifted in time.
Although the SST will make some downshifts for you, it will still allow
you to downshift at any time as long as the SST determines that the
engine will not be damaged from over-revving.
The SST will not automatically upshift, even if the engine is approaching
the RPM limit. It must be shifted manually by pressing the + button.
Engine damage may occur if excessive engine revving is held without
shifting.
PRS (Progressive Range Selection)
With the gearshift lever in D (Drive), press the – button to active PRS.
The available and selected gears will be indicated on the instrument
cluster.
All available gears will be displayed with the current gear indicated.
Press the – button again to lock out gears beginning with the highest
gear. Example: press the – button twice to lock out 6th and 5th gears.
Only the available gears will be displayed and the transmission will
automatically shift between the available gears. Press the + button to
unlock gears to allow the transmission to shift to higher gears. The
transmission will shift automatically within the gear range you select.
Automatic Transmission Adaptive Learning
This feature is designed to increase durability and provide consistent
shift feel over the life of the vehicle. A new vehicle or transmission may
have firm shifts, soft shifts or both. This operation is considered normal
and will not affect function or durability of the transmission. Over time,
the adaptive learning process will fully update transmission operation.
Additionally, whenever the battery is disconnected or a new battery
installed, the strategy must be relearned.
Brake-Shift Interlock – Floor-Shifter Assembly
WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING: When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.

WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is pressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed, it is possible that a fuse has
blown or the vehicle’s brake lamps are not operating properly. Refer to
the Fuses chapter for more information.
If the fuse is not blown and the brake lamps are working properly, the
following procedure will allow you to move the gearshift lever from P
(Park): 1. Apply the parking brake, turn the
ignition key to the off position, and
remove the key.
2. Starting at the rear of the trim
panel, using a screwdriver (or
similar tool) carefully pry up the
trim panel from rear attachments
and disconnect it from the console
to expose the inside of the
gearshift.
3. Locate the brake shift interlock
lever on the passenger side of the
shifter assembly.
4. Apply the brake pedal. Using a
screwdriver (or similar tool), press
and hold the brake shift interlock
lever while pulling the gearshift lever
out of the P (Park) position and into
the N (Neutral) position.
5. Install the trim panel.
6. Apply brake pedal, start the vehicle, and release the parking brake.
See your authorized dealer as soon as possible if this procedure is used.

USING FOUR-WHEEL DRIVE (4WD) (if equipped)
WARNING:For important information regarding safe operation
of this type of vehicle, see General Informationin theWheels
and Tires chapter.
Note: Do not use 4X4 mode on dry, hard surfaced roads. Doing so will
produce excessive noise, increase tire wear and may damage drive
components. 4X4 mode is only intended for consistently slippery or loose
surfaces.
Your 4x4 features the heavy-duty Control Trac® 4WD system which
includes a computer-operated transfer case. This unique system is
interactive with the road, continually monitoring and adjusting torque
delivery to the front and rear wheels to optimize vehicle control.
4WD Indicator Lights
The indicator lights illuminate in the message center in the
reconfigurable telltale (RTT) location under the following conditions.
Refer to Warning Lamps and Indicators in theInstrument Cluster
chapter.
Note: When a 4X4 system fault is present, the system will typically
remain in whichever 4X4 mode was selected prior to the fault condition
occurring. It will not default to 4X2 in all circumstances. When this
warning is displayed, have your vehicle serviced by an authorized dealer.
4X2- Momentarily illuminates when 2H is selected.
4X4 AUTO - Continuously illuminates when 4A is selected
4X4 - Continuously illuminates when 4H is selected.
CHECK 4X4 - Displays when a 4X4 fault is present.

4WD switch positions
WARNING:Utility and four-wheel drive vehicles are not
designed for cornering at speeds as high as passenger cars any
more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Avoid sharp turns or abrupt maneuvers in
these vehicles.
Note: The AdvanceTrac® with RSC® stability enhancement system can
be turned off manually by pressing the AdvanceTrac button, see the
Traction Control chapter for more information. This will disable the
engine management feature, allowing the vehicle to maintain full power
and enhanced momentum through the obstacle.
Note: The Control Trac selector switch should not be changed while the
rear wheels are slipping.
The Control Trac system functions in
four modes:
•2H (4X2) delivers power to the
rear wheels only. The message
center will momentarily display 4x2
when this mode is selected. This mode is appropriate for normal
on-road driving on dry pavement and provides the best fuel economy.
• 4A (4X4 AUTO) provides electronic control four-wheel drive with
power delivered to all four wheels, as required, for increased traction.
The message center will display 4A when this mode is selected. This
mode is appropriate for all on-road driving conditions, such as dry
road surfaces, wet pavement, snow, or gravel.
• 4H (4X4) provides electronically locked four-wheel drive power to
front and rear wheels. The message center will display 4X4 when this
mode is selected. This mode is not recommended for use on dry
pavement. This mode is only intended for severe winter or off-road
conditions, such as deep snow, ice or shallow sand.
Shifting between system modes
Note: Do not perform these operations if the rear wheels are slipping.
Note: Some noise may be heard as the system shifts or engages.
Press any button (4X2, 4X4 AUTO or 4X4) at a stop or while driving.
The message center may display a message indicating a 4X4 shift is in
progress. Once the shift is complete the message center will then display
the system mode selected.

How Your Vehicle Differs From Other Vehicles
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles are notdesigned for cornering at speeds as high as passenger
cars any more than low-slung sports cars are designed to perform
satisfactorily under off-road conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
Driving Off-Road With Truck and Utility Vehicles
Note: On some 4WD models, the initial shift from two-wheel drive to
four-wheel drive while the vehicle is moving can cause some momentary
clunk and ratcheting sounds. This is the front drivetrain coming up to
speed and the automatic locking hubs engaging and is not cause for
concern.
Note: Your vehicle may be equipped with a front air dam that can
become damaged (due to reduced ground clearance) when taking your
vehicle off-road. This air dam can be taken off by removing two bolts.
4WD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.

Power is supplied to all four wheels through a transfer case. On 4WD
vehicles, the transfer case allows you to select between different 4WD
modes when necessary. Information on transfer case operation and
shifting procedures can be found in this chapter. Information on transfer
case maintenance can be found in theMaintenancechapter. You should
become thoroughly familiar with this information before you operate
your vehicle.
4WD (when you select a 4WD mode) uses all four wheels to power the
vehicle. This increases traction, enabling you to drive over terrain and
road conditions that a conventional two-wheel drive vehicle cannot.
Basic Operating Principles In Special Conditions
• Do not use 4x4 on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4WD modes are only intended for consistently slippery or loose
surfaces.
• Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
• If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
• It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
• It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
If your vehicle gets stuck
WARNING: Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.

If you do stall out, do not try to turn around because you might roll over.
It is better to back down to a safe location.
Apply just enough power to the wheels to climb the hill. Too much
power will cause the tires to slip, spin or lose traction, resulting in loss of
vehicle control.Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral; instead,
disengage overdrive or manually
shift to a lower gear. When
descending a steep hill, avoid
sudden hard braking as you could
lose control. When you brake hard,
the front wheels can’t turn and if
they aren’t turning, you won’t be able to steer. The front wheels have to
be turning in order to steer the vehicle.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
pump the brakes.
Driving on snow and ice
WARNING: If you are driving in slippery conditions that require
tire chains or cables, then it is critical that you drive cautiously.
Keep speeds down, allow for longer stopping distances and avoid
aggressive steering to reduce the chances of a loss of vehicle control
which can lead to serious injury or death. If the rear end of the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.

GENERAL INFORMATION
Note:Occasional brake noise is normal. If a metal-to-metal, continuous
grinding or continuous squeal sound is present, the brake linings may be
worn out. Have them inspected by an authorized dealer. If your vehicle
has continuous vibration or shudder in the steering wheel while braking,
have your vehicle inspected by an authorized dealer.
Note: Brake dust may accumulate on the wheels, even under normal
driving conditions. Some dust is inevitable as the brakes wear and does
not contribute to brake noise. See the Vehicle Carechapter for wheel
cleaning instructions.
See theInstrument Cluster chapter for information on the
brake system warning light.
Wet brakes result in reduced braking efficiency. Gently press the brake
pedal a few times when driving from a car wash or standing water to dry
the brakes.
Brake Over Accelerator
In the event the accelerator pedal becomes stuck or entrapped, apply
steady and firm pressure to the brake pedal to slow your vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to park
(P) and apply the parking brake. Inspect the accelerator pedal and the
area around it for any items or debris that may be obstructing its
movement. If none are found and the condition persists, have your
vehicle towed to the nearest authorized dealer.
Anti-Lock Brake System
This system helps you maintain steering control during emergency stops
by keeping the brakes from locking. This lamp momentarily illuminates when you turn the ignition
on. If the light does not illuminate during start-up, remains on
or flashes, the anti-lock brake system may be disabled. Have
the system checked by an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still effective.
If the brake warning lamp illuminates when you release the
parking brake, have the system checked by an authorized
dealer.
