inflation pressure LINCOLN MKS 2015 User Guide

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 WARNING
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. However, heat caused by hot
climates or frequent high loading
conditions can accelerate the aging
process and may require tires to be
replaced 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. 275

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.
Front-wheel drive and all-wheel
drive vehicles (front tires on the left
side of the diagram) Sometimes irregular tire wear can
be corrected by rotating the tires.
USING SNOW CHAINS
WARNINGS
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. WARNINGS
Do not use snow chains or cables on
this vehicle as they may cause damage
to your vehicle which may lead to loss
of vehicle control. Snow chains have not been approved for use
on your vehicle.
The original equipment tires on your vehicle
may have an all-weather tread design to
provide traction, handling, and braking
performance in year-round driving. You may
install snow tires for improved traction when
driving in areas with sustained periods of
snow or icy driving conditions.
TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring system is
not a substitute for manually checking
tire pressure. The tire pressure should
be checked periodically (at least monthly)
using a tire gauge, see Inflating your tires in
this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire
failure, loss of control, vehicle rollover and
personal injury. 279
MKS (), enUSA Wheels and TiresE142547

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
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.
Changing Tires With a Tire Pressure
Monitoring System

MKS (), enUSA Wheels and Tires E142549

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 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
WARNINGS
The use of tire sealant may damage
your tire pressure monitoring system
and should only be used in roadside
emergencies. If you must use a sealant, the
Ford Tire Mobility Kit sealant should be used.
The tire pressure monitoring system sensor
and valve stem on the wheel must be
replaced by an authorized dealer after use of
the sealant. If the tire pressure monitor sensor
becomes damaged, it will no longer
function. See Tire Pressure
Monitoring System (page 279). Note:
The tire pressure monitoring system
indicator light will illuminate 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 while 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
279). 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.
