2015 LINCOLN NAVIGATOR check engine

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.

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.

TRAILER SWAY CONTROL
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (such as hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
Note: This feature does not prevent trailer sway, but reduces it once it
begins.
Note: This feature cannot stop all trailers from swaying.
Note: In some cases, if vehicle speed is too high, the system may turn
on multiple times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the
stability control light flashes and the message TRAILER SWAY
REDUCE SPEED appears in the information display. The first thing to
do is slow your vehicle down, then pull safely to the side of the road and
check for proper tongue load and trailer load distribution. See the Load
Carrying chapter for specific loading information.
RECOMMENDED TOWING WEIGHTS
Note: Do not exceed the trailer weight for your vehicle configuration
listed in the chart below.
Note: Make sure to take into consideration trailer frontal area. Do not
exceed:
• 36.5 feet
2(3.39 meters2) trailer frontal area for vehicles equipped
with the standard towing package.
• 60.0 feet
2(5.57 meters2) trailer frontal area for vehicles equipped
with the optional Heavy Duty package.
Note: Exceeding this limitation may significantly reduce the
performance of your towing vehicle. Selecting a trailer with a low
aerodynamic drag and rounded front design helps optimize performance
and fuel economy.
Note: For high altitude operation, reduce the gross combined weight by
2% per 1000 feet (300 meters) starting at the 1000 foot (300 meter)
elevation point.

The standard integrated hitch has two ratings depending on mode of
operation:
•Weight-carrying mode requires a draw bar and hitch ball. The draw
bar supports all the vertical tongue load of the trailer.
• Weight-distributing mode requires an aftermarket weight-distributing
system, which includes draw bar, hitch ball, spring bars and snap-up
brackets. This system distributes the vertical tongue load of the trailer
between the truck and the trailer.
Mode Maximum trailer
weight Maximum tongue
weight
Weight-carrying 6300 lb (2857 kg) 630 lb (285 kg)
Weight-distributing 9000 lb (4082 kg) 900 lb (408 kg)
Note: These are hitch ratings only. Actual vehicle ratings are dependent
on engine, transmission and axle combinations.
Weight-distributing Hitch – Vehicles without Automatic Leveling
Suspension
WARNING: Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was before attaching the trailer. Doing so will defeat the function of the
weight-distributing hitch, which may cause unpredictable handling, and
could result in serious personal injury.
When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park your vehicle, without the trailer, on a level surface.
2. Measure the height of the top of your vehicle’s front wheel opening on the fender. This is H1.
3. Attach the trailer to your vehicle without the weight-distributing bars connected.
4. Measure the height of the top of your vehicle’s front wheel opening on the fender a second time. This is H2.
5. Install and adjust the tension in the weight distributing bars so that the height of the front fender is approximately halfway between H1
and H2.
6. Check that the trailer is level or slightly nose down toward your vehicle. If not, adjust the ball height accordingly and repeat
Steps 2–6.
Once the trailer is level or slightly nose down toward the vehicle:
• Lock the bar tension adjuster in place.

Trailer Lamps
WARNING:Never connect any trailer lamp wiring to the
vehicle’s tail lamp wiring; this may damage the electrical system
resulting in a fire. Contact an authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing up to get the feel of your
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels clear curbs and other obstacles.
When Towing a Trailer
• Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
• When stopped in congested or heavy traffic during hot weather, place
the gearshift in position Pto aid engine and transmission cooling and
to help air conditioning performance.
• Turn off the speed control with heavy loads or in hilly terrain. The
speed control may turn off automatically when you are towing on
long, steep grades.
• Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as they may overheat and become less
effective.
• If your transmission is equipped with a Grade Assist or Tow/Haul
feature, use this feature when towing. This provides engine braking
and helps eliminate excessive transmission shifting for optimum fuel
economy and transmission cooling.
• If your vehicle is equipped with AdvanceTrac™ with RSC, this system
may turn on during typical cornering maneuvers with a heavily loaded
trailer. This is normal. Turning the corner at a slower speed while
towing may reduce this tendency.

•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.
