Ford Police Interceptor Sedan (2018 year). Manual — part 54

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 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 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.

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 Inflating Your Tires in this
chapter.

Understanding Your Tire Pressure
Monitoring System

The tire pressure monitoring system
measures pressure in your four road tires
and sends the tire pressure readings to
your vehicle. The low tire pressure warning
light will turn on if the tire pressure is
significantly low. Once the 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:

the edge of driver’s door or the B-Pillar),
the vehicle must be driven for at least
two minutes over 20 mph (32 km/h)
before the light turns off.

TPMS malfunction

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 2–4 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

WARNINGS

Do not use tire sealants as they may
damage the tire pressure monitoring
system.

If the tire pressure monitor sensor
becomes damaged it may not
function.

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 219). 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.

Dissimilar Spare Wheel and Tire
Assembly Information

WARNING

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

If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by Ford. If the dissimilar spare tire or wheel
is damaged, it should be replaced rather
than repaired.

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
and can be one of three types:

1. T-type mini-spare: This spare tire
begins with the letter T for tire size and
may have Temporary Use Only molded in
the sidewall.
