USING SNOW CHAINS
WARNING: Do not exceed 30 mph
(50 km/h). Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not use snow chains
on snow-free roads. WARNING:
Only fit snow chains to
specified tires. WARNING:
If your vehicle is fitted
with wheel trims, remove them before
fitting snow chains. WARNING:
If you choose to install
snow tires on your vehicle, they must be
the same size, construction, and load range
as the original tires listed on the tire
placard, and they must be installed on all
four wheels. Mixing tires of different size
or construction on your vehicle can
adversely affect your vehicle's handling
and braking, and may lead to loss of
vehicle control. WARNING:
Wheels and tires must
be the same size, load index and speed
rating as those originally fitted on the
vehicle. Use of any other tire or wheel can
affect the safety and performance of your
vehicle. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure. Follow
the recommended tire inflation pressures found on the Safety Compliance
Certification label, or the Tire Label on the
B-Pillar or the edge of the driver door.
Failure to follow this instruction could result
in loss of vehicle control, vehicle rollover,
or personal injury or death.
Only use snow chains on rear wheels. Install
snow chains in pairs. Do not use
self-tensioning snow chains.
Only use snow chains on the following
specified tire sizes. Only install chains that
are 15mm or less (SAE Class S chains).
• 265/70R17
• 275/65R18
We recommend you use steel wheels of the
same size and specification if snow chains
are required because chains may chip
aluminum wheels.
Follow these guidelines when using snow
tires and traction devices:

CHECKING THE TIRE PRESSURES
Safe operation of your vehicle requires
that your tires are properly inflated.
Every day before you drive, check your
tires.
At least once a month and before long
trips, inspect each tire and check the tire
pressure with a tire gauge. Inflate all
tires to the recommended inflation
pressure. See Inflating the Tires (page
449).
INFLATING THE TIRES 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!
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.
Use the recommended cold inflation
pressure for optimum tire performance
and wear. Under-inflation or
over-inflation may cause uneven
treadwear patterns.
Inflate your tires to the recommended
inflation pressure even if it is less than
the maximum inflation pressure
information found on the tire. You can
find the tire label with the recommended
tire inflation pressure next to the tire size
on the B-Pillar or the edge of the driver
door. The recommended tire inflation pressure
is also 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 on
the B-pillar, or on the edge of the driver
door.
Failure to follow the tire pressure
recommendations can cause uneven
treadwear patterns and adversely affect
the way your vehicle handles.
INSPECTING THE TIRE FOR WEAR
449
2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Tire CareE142546
When the tread is worn down to one
sixteenth of an inch (2 mm), tires must
be replaced to help prevent your vehicle
from skidding and hydroplaning. Built-in
treadwear indicators, or wear bars,
which look like narrow strips of smooth
rubber across the tread will appear on
the tire when the tread is worn down to
one sixteenth of an inch (2 mm).
When the tire tread wears down to the
same height as these wear bars, the tire
is worn out and must be replaced.
The tires should also be balanced
periodically. An unbalanced tire and
wheel assembly may result in irregular
tire wear.
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.
INSPECTING THE TIRE FOR
DAMAGE
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
dismounted 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.
Periodically inspect the tire treads and
sidewalls for damage, such as bulges in
the tread or sidewalls, cracks in the
tread groove and separation in the tread
or sidewall. If damage is observed or
suspected, have the tire inspected by a
tire professional.
Safety Practices WARNING: If your vehicle is
stuck in snow, mud or sand, do not
rapidly spin the tires; spinning the tires
can tear the tire and cause an
explosion. A tire can explode in as little
as three to five seconds. WARNING:
Do not spin the
wheels at over 34 mph (55 km/h). The
tires may fail and injure a passenger
or bystander.
Highway Hazards
No matter how carefully you drive, there
is always the possibility that you could
eventually have a flat tire on the
highway. Drive slowly to the closest safe
area out of traffic. This could further
damage the flat tire, but your safety is
more important.
450
2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Tire Care
If you feel a sudden vibration or ride
disturbance while driving, or you suspect
your tire or vehicle has been damaged,
immediately reduce your speed. Drive
with caution until you can safely pull off
the road. Stop and inspect the tires for
damage. If a tire is under-inflated or
damaged, deflate it, remove the wheel
and replace it with your spare tire and
wheel. If you cannot detect a cause,
have the vehicle towed to the nearest
repair facility or tire dealer to have the
vehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or pothole
can cause the front end of your vehicle
to become misaligned or cause damage
to your tires. If your vehicle seems to
pull to one side when you are driving,
the wheels could be out of alignment.
Have an authorized dealer check the
wheel alignment periodically.
Wheel misalignment in the front or the
rear can cause uneven and rapid
treadwear of your tires and should be
corrected by an authorized dealer.
INSPECTING THE WHEEL VALVE
STEMS
Check the valve stems for holes, cracks,
or cuts that could permit air leakage.
TIRE ROTATION
WARNING: If the tire label shows
different tire pressures for the front
and rear tires and the vehicle has a
tire pressure monitoring system, then
you need to update the settings for
the system sensors. Always perform
the system reset procedure after tire
rotation. If you do not reset the system,
it may not provide a low tire pressure
warning when necessary.
Rotating your tires at the recommended
interval will help your tires wear more
evenly, providing better tire performance
and longer tire life. Note:
If your tires show any uneven
wear have the alignment checked by
an authorized dealer before rotating
tires.
Note: If you have a dissimilar spare
wheel and tire assembly, it is intended
for temporary use only and should not
be used in a tire rotation.
Note: After having your tires rotated,
inflation pressure must be checked and
adjusted to the vehicle requirements.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoring
system measures the vehicle's tire
pressures. A warning lamp
illuminates if one or more tires are
significantly underinflated or if there is a
system malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW WARNING: If the tire pressure
monitor sensor becomes damaged it may
not function. 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!
WARNING:
To determine the
required pressure(s) for your vehicle, see
the Safety Compliance Certification Label
(on the door hinge pillar, door-latch post
or the door edge that meets the door-latch
post, next to the driver seat) or the Tire
Label on the B-Pillar or the edge of the
driver door.
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 may 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.

TIRE PRESSURE MONITORING
SYSTEM LIMITATIONS
When the outside temperature drops
significantly, the tire pressure could decrease
and activate the low tire pressure warning
lamp.
The warning lamp could also illuminate when
you use a spare wheel, or tire sealant from
the inflator kit.
Note:
Regularly checking the vehicle tire
pressures can reduce the possibility for the
warning lamp to illuminate due to outside
air temperature changes.
Note: After you inflate the tires to the
recommended pressure it could take up to
two minutes of driving over 20 mph (32 km/h)
for the warning indicator to turn off. VIEWING THE TIRE PRESSURES
