•
Higher - to allow higher load carrying
capacity and to allow it to travel over
rough terrain without getting hung up or
damaging underbody components.
• Shorter - to give it the capability to
approach inclines and drive over the
crest of a hill without getting hung up or
damaging underbody components. All
other things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs
than a vehicle with a longer wheelbase.
• Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, Sport utility vehicles and trucks
often 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 us 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.
Glossary of Tire Terminology
*
Tire label: A label showing the original
equipment tire sizes, recommended
inflation pressure and the maximum
weight the vehicle can carry.

Tire Identification Number (TIN): A
number on the sidewall of each tire
providing information about the tire
brand and manufacturing plant, tire size
and date of manufacture. Also referred
to as DOT code.
*
Inflation pressure: A measure of the
amount of air in a tire.
407

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!
Always inflate your tires to the our
recommended inflation pressure even
if it is less than the maximum inflation
pressure information found on the tire.
Our 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 us, 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.
414
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Wheels and Tires
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle
has tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should
determine the proper tire inflation pressure
for those tires).
As an added safety feature, your vehicle has
been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates a
low tire pressure telltale when one or more
of your tires is significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and could affect
the vehicle ’s handling and stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’
s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system will not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions could occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or
more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.

When Inflating Your Tires
WARNING: Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure to
follow this instruction could result in
personal injury or death.
When putting air into your tires (such as at a
gas station or in your garage), the tire
pressure monitoring system will not respond
immediately to the air added to your tires.
It could take up to two minutes of driving
over
20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure.
How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system monitors
tire pressure in each pneumatic tire. While
driving in a normal manner, a typical
passenger tire inflation pressure could
increase about
2–4 psi (14–28 kPa) from a
cold start situation. If the vehicle is stationary
overnight with the outside temperature significantly lower than the daytime
temperature, the tire pressure could
decrease about
3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value could be detected by
the tire pressure monitoring system as being
significantly lower than the recommended
inflation pressure and activate the system
warning light for low tire pressure. If the low
tire pressure warning light is on, visually
check each tire to verify that no tire is flat. If
one or more tires are flat, repair as
necessary. Check the air pressure in the road
tires. If any tire is under-inflated, carefully
drive the vehicle to the nearest location
where air can be added to the tires. Inflate
all the tires to the recommended inflation
pressure.
CHANGING A ROAD WHEEL WARNING:
If the tire pressure
monitor sensor becomes damaged it may
not function. Note:
You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on this vehicle.
If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe place
on the side of the road.
Have a flat serviced by an authorized dealer
in order to prevent damage to the system
sensors.
See Tire Pressure Monitoring
System (page 421). Replace the spare tire
with a road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the system
sensor for damage.

HD Radio Reception and Station Troubleshooting
Potential reception issues
If you are listening to a multicast station and you are on the fringe of\
the reception area, the station may mute
due to weak signal strength.
Reception area
If you are listening to HD1, the system switches back to the analog broa\
dcast until the digital broadcast is
available again. However, if you are listening to any of the possible HD2-HD7 multicast channels\
, the station
mutes and stays muted unless it is able to connect to the digital signal\
again.
When the system first receives a station, aside from HD2-HD7 multicast s\
tations, it first plays the station in the
analog version. Once the receiver verifies the station is an HD Radio station, it shifts to the digital version.
Depending on the station quality, you may hear a slight sound change when the station changes from analo\
g
to digital. Blending is the shift from analog to digital sound or digita\
l back to analog sound.
Station blending
In order to provide the best possible
experience, use the contact form to report
any station issues found while listening to a
station broadcasting with HD Radio
technology. Independent entities own and
operate each station. These stations are
responsible for the accuracy of all audio
streams and data fields.
