Low Tire PressureIt will illuminate when your tire pressure is low. If the lamp
remains on with the engine running or when driving, check
your tire pressure as soon as possible.
The lamp also illuminates momentarily when you switch the ignition on
to confirm the lamp is functional. If it does not illuminate when you
switch the ignition on, or begins to flash at any time, have the system
checked by an authorized dealer. Refer to Wheels and Tiresfor more
information.
Low Washer Fluid
It will illuminate when the windshield washer fluid is low.
Parking Lamps It will illuminate when you switch the parking lamps on.
Powertrain Fault Illuminates when a powertrain fault has been detected. Contact
your authorized dealer as soon as possible.
Service Engine Soon Theservice engine soon indicator light illuminates when the
ignition is first turned to the on position to check the bulb and
to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, the “service engine soon”
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds the “service
engine soon” light blinks eight times, it means that the vehicle is not
ready for I/M testing. See the Readiness for inspection/maintenance
(I/M) testing in theFuel and Refueling chapter.
Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II) in theFuel and Refueling chapter. If
the light is blinking, engine misfire is occurring which could damage your
catalytic converter. Drive in a moderate fashion (avoid heavy acceleration
and deceleration) and have your vehicle serviced immediately by your
authorized dealer.

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.
Four-Wheel Drive (If Equipped) 179
2015 Navigator(nav)
Owners Guide gf, 2nd Printing, December 2014
USA (fus)
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.

Note:Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note: Do not rock the vehicle for more than a few minutes or damage to
the transmission and tires may occur or the engine may overheat.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Emergency maneuvers
• In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid over-driving your vehicle, i.e., turn
the steering wheel only as rapidly and as far as required to avoid the
emergency. Excessive steering will result in less vehicle control, not
more. Additionally, smooth variations of the accelerator and/or brake
pedal pressure should be utilized if changes in vehicle speed are called
for. Avoid abrupt steering, acceleration or braking which could result
in an increased risk of loss of vehicle control, vehicle rollover and/or
personal injury. Use all available road surface to return the vehicle to a
safe direction of travel.
• In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
• If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
Note: Driving through deep water may damage the vehicle.
If you must drive through high water, drive slowly. Traction or brake
capability may be limited.

When driving through water, determine the depth; avoid water higher
than the bottom of the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.“Tread Lightly” is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest
Service and the Bureau of Land Management in encouraging you to help
preserve our national forest and other public and private lands by
“treading lightly.”
Driving on hilly or sloping terrain
Note: Avoid driving crosswise or turning on steep slopes or hills.
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down. . A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
When climbing a steep slope or hill, start in a lower gear rather than
downshifting to a lower gear from a higher gear once the ascent has
started. This reduces strain on the engine and the possibility of stalling.
