LINCOLN NAVIGATOR 2017 Owners Manual

As a result of the above dimensional
differences, Sport utility vehicles 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
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.

Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half (1 ½) times as well
on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual
conditions of their use, however, and
may depart significantly from the norm
due to variations in driving habits,
service practices, and differences in
road characteristics and climate.
Traction AA A B C
WARNING
The traction grade assigned to this
tire is based on straight-ahead
braking traction tests, and does not
include acceleration, cornering,
hydroplaning or peak traction
characteristics. The traction grades, from highest to
lowest are AA, A, B, and C. The grades
represent the tire
’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature A B C WARNING
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure. The temperature grades are A (the
highest), B and C, representing the tire
’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.

See
Load Carrying (page 209).
Inflating Your Tires
Safe operation of your vehicle requires
that your tires are properly inflated.
Remember that a tire can lose up to half
of its air pressure without appearing flat.
Every day before you drive, check your
tires. If one looks lower than the others,
use a tire gauge to check pressure of all
tires and adjust if required.
At least once a month and before long
trips, inspect each tire and check the tire
pressure with a tire gauge (including
spare, if equipped). Inflate all tires to the
inflation pressure recommended by Ford
Motor Company. You are strongly urged to buy a reliable
tire pressure gauge, as automatic
service station gauges may be
inaccurate. Ford recommends the use
of a digital or dial-type tire pressure
gauge rather than a stick-type tire
pressure gauge.
Use the recommended cold inflation
pressure for optimum tire performance
and wear. Under-inflation or
over-inflation may cause uneven
treadwear patterns.
WARNING
Under-inflation is the most common
cause of tire failures and may result
in severe tire cracking, tread separation
or blowout, with unexpected loss of
vehicle control and increased risk of
injury. Under-inflation increases sidewall
flexing and rolling resistance, resulting
in heat buildup and internal damage to
the tire. It also may result in unnecessary
tire stress, irregular wear, loss of vehicle
control and accidents. A tire can lose up
to half of its air pressure and not appear
to be flat! 305
Navigator (TB5) Canada/United States of America, enUSA, First Printing Wheels and Tires

Always inflate your tires to the Ford
recommended inflation pressure even
if it is less than the maximum inflation
pressure information found on the tire.
The Ford recommended tire inflation
pressure is found on the Safety
Compliance Certification Label or Tire
Label (affixed to either the door hinge
pillar, door-latch post, or the door edge
that meets the door-latch post, next to
the driver's seating position), or Tire
Label located on the B-pillar or the edge
of the driver's door. Failure to follow the
tire pressure recommendations can
cause uneven treadwear patterns and
adversely affect the way your vehicle
handles.
Note:
Do not reduce tire pressure to
change the ride characteristics of the
vehicle. If you do not maintain the
inflation pressure at the levels specified
by Ford, your vehicle may experience a
condition known as shimmy. Shimmy is
a severe vibration and oscillation in the
steering wheel after the vehicle travels
over a bump or dip in the road that does
not dampen out by itself. Shimmy may
result from significant under-inflation of
the tires, improper tires (load range, size,
or type), or vehicle modifications such
as lift-kits. In the event that your vehicle
experiences shimmy, you should slowly
reduce speed by either lifting off the
accelerator pedal or lightly applying the
brakes. The shimmy will cease as the
vehicle speed decreases.
Maximum Inflation Pressure is the tire
manufacturer's maximum permissible
pressure and the pressure at which the
maximum load can be carried by the tire.
This pressure is normally higher than the
manufacturer’ s recommended cold
inflation pressure which can be found
on the Safety Compliance Certification Label (affixed to either the door hinge
pillar, door-latch post, or the door edge
that meets the door-latch post, next to
the driver's seating position), or Tire
Label located on the B-pillar or the edge
of the driver's door. The cold inflation
pressure should never be set lower than
the recommended pressure on the
Safety Compliance Certification Label
or Tire Label.
When weather temperature changes
occur, tire inflation pressures also
change. A 10°F (6°C) temperature drop
can cause a corresponding drop of 1 psi
(7 kPa) in inflation pressure. Check your
tire pressures frequently and adjust
them to the proper pressure which can
be found on the Safety Compliance
Certification Label or Tire Label.
To check the pressure in your tire(s):
1. Make sure the tires are cool, meaning
they are not hot from driving even a
mile.
306
Navigator (TB5) Canada/United States of America, enUSA, First Printing Wheels and Tires

Note:
If you are checking tire pressure
when the tire is hot, (for example, driven
more than 1 mile [1.6 kilometers]), never
bleed or reduce air pressure. The tires
are hot from driving and it is normal for
pressures to increase above
recommended cold pressures. A hot tire
at or below recommended cold inflation
pressure could be significantly
under-inflated.
Note: If you have to drive a distance to
get air for your tire(s), check and record
the tire pressure first and add the
appropriate air pressure when you get
to the pump. It is normal for tires to heat
up and the air pressure inside to go up
as you drive.
2. Remove the cap from the valve on
one tire, then firmly press the tire gauge
onto the valve and measure the
pressure.
3. Add enough air to reach the
recommended air pressure. Note:
If you overfill the tire, release air
by pressing on the metal stem in the
center of the valve. Then recheck the
pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,
including the spare.
Note: Some spare tires operate at a
higher inflation pressure than the other
tires. For T type mini-spare tires, see the
Dissimilar spare wheel and tire
assembly information for a description.
Store and maintain at 60 psi (4.15 bar).
For full-size and dissimilar spare tires,
see the Dissimilar spare wheel and tire
assembly information for a description.
Store and maintain at the higher of the
front and rear inflation pressure as
shown on the Safety Compliance
Certification Label or Tire Label.
6. Visually inspect the tires to make sure
there are no nails or other objects
embedded that could poke a hole in the
tire and cause an air leak. 7. Check the sidewalls to make sure
there are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel Valve
Stems
Periodically inspect the tire treads for
uneven or excessive wear and remove
objects such as stones, nails or glass
that may be wedged in the tread
grooves. Check the tire and valve stems
for holes, cracks, or cuts that may permit
air leakage and repair or replace the tire
and replace the valve stem. Inspect the
tire sidewalls for cracking, cuts, bruises
and other signs of damage or excessive
wear. If internal damage to the tire is
suspected, have the tire demounted and
inspected in case it needs to be repaired
or replaced. For your safety, tires that
are damaged or show signs of excessive
wear should not be used because they
are more likely to blow out or fail.
