Lincoln Aviator (2020 year). Instruction — part 25

*Avoid fast starts, stops and turns

*Avoid potholes and objects on the road

*Do not run over curbs or hit the tire
against a curb when parking

Highway Hazards

No matter how carefully you drive, there
is 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 are 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 (if
equipped) 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.

Wheels and Tires

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 will help your tires wear more
evenly, providing better tire performance
and longer tire life. Sometimes irregular
tire wear can be corrected by rotating
the tires. See Scheduled Maintenance

(page 512).

USING SUMMER TIRES

Summer tires provide superior performance
on wet and dry roads. Summer tires do not
have the Mud and Snow (M+S or M/S) tire
traction rating on the tire side wall. Since
summer tires do not have the same traction
performance as All-season or Snow tires, we
do not recommend using summer tires when
temperatures drop to approximately 45°F
(7°C) or below (depending on tire wear and
environmental conditions) or in snow and ice

conditions. Like any tire, summer tire
performance is affected by tire wear and
environmental conditions. If you must drive
in those conditions, we recommend using
Mud and Snow (M+S, M/S), All-season or
Snow tires.

Always store your summer tires indoors at
temperatures above 19°F (-7°C). The rubber
compounds used in these tires lose flexibility
and may develop surface cracks in the tread
area at temperatures below 19°F (-7°C). If the
tires have been subjected to 19°F (-7°C) or
less, warm them in a heated space to at least
41°F (5°C) for at least 24 hours before
installing them on a vehicle, or moving the
vehicle with the tires installed, or checking
tire inflation. Do not place tires near heaters
or heating devices used to warm the room
where the tires are stored. Do not apply heat
or blow heated air directly on the tires.
Always inspect the tires after storage periods
and before use.

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: 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.

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:

•

255/60R19
•

Only install chains that are 10 mm or
less.

•

255/55R20
•

Only install chains that are 10 mm or
less.

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:

•

If possible, avoid fully loading your
vehicle.

•

Purchase snow chains from a
manufacturer that clearly labels body to
tire dimension restrictions.

•

When driving with snow chains do not
exceed 30 mph (50 km/h) or the
maximum speed recommended by the
chain manufacturer, whichever is less.

•

Drive cautiously. If you hear the snow
chains rub or bang against the vehicle,
stop and tighten them. If this does not
work, remove the snow chains to prevent
vehicle damage.

•

Remove the snow chains when they are
no longer needed. Do not use snow
chains on dry roads.

395

•

If a temporary spare wheel is mounted
on your vehicle, do not use snow chains
on the axle with the temporary spare
wheel.

•

Use snow chains that fit against the
sidewall of the tire to prevent the chains
from touching the wheel rims or
suspension, see following illustration.

TIRE PRESSURE MONITORING
SYSTEM

WARNING: The tire pressure

monitoring system is not a substitute for
instructionly 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 may cause
damage to the tire pressure monitoring
system sensor.

Note: If the tire pressure monitoring system
sensor becomes damaged, it may not
function.

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.

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 may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from

397

Aviator (CTV) Canada/United States of America, enUSA, Edition date: 201902, Second-Printing

Wheels and Tires

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 may not cause harmful

interference, and

2. This device must accept any interference

received, including interference that may
cause undesired operation.

Note: Changes or modifications not
expressively approved by the party
responsible for compliance could void the
user's authority to operate the equipment.
The term "IC:" before the radio certification
number only signifies that Industry Canada
technical specifications were met.

Changing Tires With a Tire Pressure
Monitoring System

E142549

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

E250820

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 127). The low
tire pressure warning light will turn on if the
tire pressure is significantly low. Once the

398

Aviator (CTV) Canada/United States of America, enUSA, Edition date: 201902, Second-Printing

Wheels and Tires

light 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 may not respond
immediately to the air added to your tires.

It may 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 may
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 may decrease
about 3 psi (21 kPa) for a drop of 30°F (17°C)
in ambient temperature. This lower pressure
value may 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 the 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 tire
pressure monitoring system sensors. See
Tire Pressure Monitoring System (page 397).
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 tire pressure monitoring
system sensor for damage.

than when you are changing a wheel in an
emergency.

WARNING: Check that the vehicle

jack is not damaged or deformed and the
thread is lubricated and clean.

WARNING: When one of the front

wheels is off the ground, the transmission
alone will not prevent the vehicle from
moving or slipping off the jack, even if the
transmission is in park (P).

WARNING: To help prevent your

vehicle from moving when changing a
wheel, shift the transmission into park (P),
set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel, place
an appropriate block or wheel chock on
the right rear wheel.

WARNING: Always use the jack

provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. If you
are unsure if the jack capacity is adequate,
contact the authorized dealer.

WARNING: Failure to follow these

guidelines could result in an increased risk
of loss of vehicle control, injury or death.

WARNING: Use only the specified

jacking points. If you use other positions,
you may damage the body, steering,
suspension, engine, braking system or the
fuel lines.

WARNING: Do not work on your

vehicle when the jack is the only support.
