2015 LINCOLN NAVIGATOR tire type

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.

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.

•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.

GENERAL INFORMATION
Notice to Utility Vehicle, Van and Truck Owners
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles. To reduce the risk of serious
injury or death from a rollover or other crash you must:
• Avoid sharp turns and abrupt maneuvers.
• Drive at safe speeds for the conditions.
• Keep tires properly inflated.
• Never overload or improperly load your vehicle.
• Make sure every passenger is properly restrained.
WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
All occupants must wear seat belts. Children and infants must use
appropriate restraints to minimize the risk of injury or ejection.
Utility vehicles, vans and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles, vans and
trucks 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.
Four-Wheel Drive System (If Equipped)
WARNING: Do not become overconfident in the ability of
four-wheel drive vehicles. Although a four-wheel drive vehicle
may accelerate better than a two-wheel drive vehicle in low-traction
situations, it will not stop any faster than two-wheel drive vehicles.
Always drive at a safe speed.
A vehicle equipped with four-wheel drive (when selected) has the ability
to use all four wheels to power itself. This increases traction which may
enable you to safely drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.

•Narrower – to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, sport-utility vehicles,
vans and trucks often will have a
higher center of gravity and a
greater difference in center of
gravity between the loaded and
unloaded condition.
These differences that make your
vehicle so versatile also make it
handle differently than an ordinary
passenger car.
TIRE CARE
Information About Uniform Tire Quality Grading Tire Quality Grades apply to new
pneumatic passenger car tires. The Tire
Quality Grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
• Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic passenger car tires. They do
not apply to deep tread, winter-type snow tires, space-saver or
temporary use spare tires, light truck or LT type tires, tires with nominal
rim diameters of 10 to 12 inches or limited production tires as defined in
Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades: The U.S.
Department of Transportation requires Ford Motor Company to give you
the following information about tire grades exactly as the government
has written it.
