inflation pressure LINCOLN NAVIGATOR 2017 User Guide

Improper or inadequate vehicle
maintenance can cause tires to wear
abnormally. Inspect all your tires,
including the spare, frequently, and
replace them if one or more of the
following conditions exist:
Tire Wear When the tread is worn down to one
sixteenth of an inch (2 millimeters), 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 millimeters).
When the tire tread wears down to the
same height as these wear bars, the tire
is worn out and must be replaced.
Damage
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. Tires can be damaged
during off-road use, so inspection after
off-road use is also recommended.
Age WARNINGS
Tires degrade over time depending
on many factors such as weather,
storage conditions, and conditions of
use (load, speed, inflation pressure) the
tires experience throughout their lives. In general, tires should be replaced
after six years regardless of tread
wear or even if they have not been used.
However, heat caused by hot climates
or frequent high-load conditions can
accelerate the aging process and may
require you to replace tires more
frequently. You should replace your spare tire
when you replace the road tires or
after six years due to aging even if it has
not been used. 308

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.

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.
312
Navigator (TB5) Canada/United States of America, enUSA, First Printing Wheels and TiresE142548

•
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. 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.
313
Navigator (TB5) Canada/United States of America, enUSA, First Printing Wheels and Tires

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 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.
The tire pressure monitoring system
complies with part 15 of the FCC rules and
with RSS-210 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.
This device complies with part 15 of the FCC

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.

When Inflating Your Tires
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 to 4 psi (14 to 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 of30°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.
317
Navigator (TB5) Canada/United States of America, enUSA, First Printing Wheels and Tires

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.
Tire Pressure Monitoring System Reset
Procedure
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. Note:
You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation on vehicles that require
different recommended tire pressures in the
front tires as compared to the rear tires. Overview
To provide the vehicle's load carrying
capability, some vehicles require different
recommended tire pressures in the front tires
as compared to the rear tires. The tire
pressure monitoring system equipped on
these vehicles is designed to illuminate the
low tire pressure warning light at two
different pressures; one for the front tires
and one for the rear tires.
Since tires need to be rotated to provide
consistent performance and maximum tire
life, the tire pressure monitoring system
needs to know when the tires are rotated to
determine which set of tires are on the front
and which are on the rear. With this
information, the system can detect and
properly warn of low tire pressures.
System reset tips:
•
To reduce the chances of interference
from another vehicle, perform the system
reset procedure at least three feet (one
meter) away from another Ford Motor
Company vehicle undergoing the system
reset procedure at the same time.
• Do not wait more than two minutes
between resetting each tire sensor or the
system will time-out and the entire
procedure will have to be repeated on
all four wheels.
• A double horn will sound indicating the
need to repeat the procedure.
Performing the System Reset Procedure
Read the entire procedure before attempting.
1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes, then park
in a safe location where you can easily
get to all four tires and have access to
an air pump.
2. Place the ignition in the off position and keep the key in the ignition.
3. Cycle the ignition to the on position with
the engine off.
