2021 LINCOLN NAVIGATOR Owners Manual

Highway Hazards
No matter how carefully you drive
there
’s always the possibility that you
may eventually have a flat tire on the
highway. Drive slowly to the closest safe
area out of traffic. This may further
damage the flat tire, but your safety is
more important.
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 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’re driving, the
wheels may 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.
Front-wheel drive vehicles and those
with an independent rear suspension
may require alignment of all four wheels.
The tires should also be balanced
periodically. An unbalanced tire and
wheel assembly may result in irregular
tire wear.
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.
Note: If your tires show uneven wear
ask an authorized dealer to check for
and correct any wheel misalignment,
tire imbalance or mechanical problem
involved before tire rotation.

Note:
Your vehicle may be equipped
with a dissimilar spare wheel and tire
assembly. A dissimilar spare wheel and
tire assembly is defined as a spare
wheel and tire assembly that is different
in brand, size or appearance from the
road tires and wheels. 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.
Rotating your tires at the recommended
interval (as indicated in the Scheduled
Maintenance chapter) will help your tires
wear more evenly, providing better tire
performance and longer tire life.
Rear-wheel drive vehicles and
four-wheel drive vehicles (front tires at
left of diagram) Sometimes irregular tire wear can be
corrected by rotating the tires.
USING SNOW CHAINS
WARNING: Snow tires must be the
same size, load index and speed rating as
those originally provided by Ford. Use of
any tire or wheel not recommended by
Ford can affect the safety and performance
of your vehicle, which could result in an
increased risk of loss of control, vehicle
rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels can cause steering,
suspension, axle, transfer case or power
transfer unit failure. Follow the Ford
recommended tire inflation pressure found
on 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 Tire
Label on the B-Pillar or 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.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need to
use cables, it is recommended that steel
wheels (of the same size and specifications)
be used, as cables may chip aluminum
wheels.

Follow these guidelines when using snow
tires and chains:
•
If possible, avoid fully loading your
vehicle.
• Use only cable type chains or chains
offered by Ford/Lincoln as an accessory
or equivalent. Other conventional link
type chains may contact and cause
damage to the vehicle's wheel house
and/or body.
• Do not install chains on the front tires as
this may interfere with suspension
components.
• Only certain snow cables or chains have
been approved by Ford/Lincoln as safe
for use on your vehicle with the following
tires: 265/70R17 and 275/65R18.
• You should install snow cables or chains
that have been rated as SAE Class S.
• Install chains securely, verifying that the
chains do not touch any wiring, brake
lines, or fuel lines.
• Do not exceed 31 mph (50 km/h) or less
if recommended by the chain
manufacturer while using snow chains. •
Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does not
work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when they are no
longer needed. Do not use tire chains on
dry roads.
• Purchase chains or cables from a
manufacturer that clearly labels body to
tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the rear tires only.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer. TIRE PRESSURE MONITORING
SYSTEM WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to correctly
maintain tire pressures could increase the
risk of tire failure, loss of control, vehicle
rollover and personal injury.
Note: You should only use tire sealants in
roadside emergencies as they could cause
damage to the tire pressure monitoring
system sensor.
Note: If the tire pressure monitoring system
sensor becomes damaged, it will not
function.
424
Navigator (TB9) Canada/United States of America, enUSA, First-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.
This device complies with Part 15 of the FCC
Rules and with License exempt RSS
Standards of Industry Canada. Operation is
subject to the following two conditions:
1. This device will not cause harmful
interference, and
2. This device must accept any interference

Changing Tires With a Tire Pressure
Monitoring System
Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and
is not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor.
You should always have your tires serviced
by an authorized dealer. Check the tire pressure periodically (at least
monthly) using an accurate tire gauge. See
When Inflating Your Tires in this chapter.
Understanding Your Tire Pressure
Monitoring System The tire pressure monitoring system
measures pressure in your road tires and
sends the tire pressure readings to your
vehicle. You can view the tire pressure
readings through the information display.
See General Information (page 134). The low
tire pressure warning light will turn on if the
tire pressure is significantly low. Once thelight is illuminated, your tires are
under-inflated and need to be inflated to the
manufacturer’
s recommended tire pressure.
Even if the light turns on and a short time
later turns off, your tire pressure still needs
to be checked.
When Your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.

When You Believe Your System is Not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when your
tires need air. It can also warn you in the
event the system is no longer capable of
functioning as intended. See the following
chart for information concerning your tire
pressure monitoring system:

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 424). 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.
