Ford Police Interceptor Utility (2018 year). Manual — part 57

In regions with snow and ice
during the winter months,
installation of snow tires may be
desirable. Snow tires will usually
exhibit a drop in dry pavement
handling, but may show an
increase in snow and ice traction.
When snow tires are used, they
should be installed on all four
wheels, never on the drive wheels
only.

Tire storage

Most high performance tires are
made with a nylon overlay. As
such, the following steps should
be taken to avoid flatspotting
when the vehicles are not used for
a period of time.

•

Fleets should store the vehicles
with 44 psi (303 kPa) in the

tires.

•

If the vehicle is stored for
periods longer than 30 days,
you should move it several feet
at least once during each
30-day period, so that a
different portion of the tread
contacts the ground.

•

Tire pressure should be
reduced to the recommended
pressure shown on the vehicle
certification label before the
vehicle is placed back into
service.

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 vehicle
control, vehicle rollover, personal injury,
and death. Additionally, the use of
non-recommended tires and wheels could
cause steering, suspension, axle, transfer
case, or power transfer unit failure. It is also
strongly advised to follow the Ford
recommended tire inflation pressure found
on the Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door edge
that meets the door-latch post, next to the
driver’s seating position), or Tire Label
which is located 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 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 traction devices:
•

If possible, avoid fully loading your
vehicle.

•

For police sedan, 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.

•

For police utility, use only SAE Class S
snow chains, snow cables or equivalent
on the front axle for 245/55 R18
equipped vehicles. The use of snow
chains, snow cables or other traction
assist devices that are larger than SAE
Class S may cause damage to your
vehicle’s wheel house, suspension
and/or body.

•

Do not install tire chains, cables, or
optional traction devices on the rear
tires. This could cause damage to the
vehicle’s wheel house or body.

•

Install cable chains securely, verifying
that the cables do not touch any wiring,
brake lines or fuel lines.

•

When driving with tire cables do not
exceed 30 mph (48 km/h) or the
maximum speed recommended by the
chain manufacturer, whichever is less.

•

Drive cautiously. If you hear the cables
rub or bang against your vehicle, stop
and retighten the cables. If this does
not work, remove the cables to prevent
damage to your vehicle.

•

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

If you have any questions regarding snow
chains or cables, contact an 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 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.

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 79). 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:
