INFLATING YOUR TIRES
Safe operation of your vehicle requires that your tires are properly
inflated. Remember that a tire can lose up to half of its air pressure
without appearing flat.
Every day before you drive, check your tires. If one looks lower than the
others, use a tire gauge to check pressure of all tires and adjust if required.
At least once a month and before long trips, inspect each tire and check
the tire pressure with a tire gauge (including spare, if equipped). Inflate
all tires to the inflation pressure recommended by Ford Motor Company.
WARNING:Under-inflation is the most common cause of tire
failures and may result in severe tire cracking, tread separation
or blowout, with unexpected loss of vehicle control and increased risk
of injury. Under-inflation increases sidewall flexing and rolling
resistance, resulting in heat build-up and internal damage to the tire. It
also may result in unnecessary tire stress, irregular wear, loss of vehicle
control and accidents. A tire can lose up to half of its air pressure and
not appear to be flat!
You are strongly urged to buy a reliable tire pressure gauge, as automatic
service station gauges may be inaccurate. Ford recommends the use of a
digital or dial-type tire pressure gauge rather than a stick-type tire
pressure gauge.
Use the recommended cold inflation pressure for optimum tire
performance and wear. Under-inflation or over-inflation may cause
uneven treadwear patterns.
Always inflate your tires to the Ford recommended inflation pressure
even if it is less than the maximum inflation pressure information found
on the tire. The Ford recommended tire inflation pressure is 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’s door. Failure to follow the tire
pressure recommendations can cause uneven treadwear patterns and
adversely affect the way your vehicle handles.
Maximum Permissible Inflation Pressureis the tire manufacturer’s
maximum permissible pressure or the pressure at which the maximum
load can be carried by the tire. This pressure is normally higher than the
manufacturer’s recommended cold inflation pressure which can be found
on the Safety Compliance Certification Label (affixed to either the door

Tire Replacement Requirements
WARNING:Only use replacement tires and wheels that are the
same size, load index, speed rating and type (such as P-metric
versus LT-metric or all-season versus all-terrain) as those originally
provided by Ford. The recommended tire and wheel size may be found on
either 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 the Tire Label which is
located on the B-Pillar or edge of the driver’s door. If this information is not
found on these labels, then you should contact your authorized dealer as
soon as possible. 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. If you have questions regarding tire replacement, contact your
authorized dealer as soon as possible.
WARNING:When mounting replacement tires and wheels, you
should not exceed the maximum pressure indicated on the
sidewall of the tire to set the beads without additional precautions
listed below. If the beads do not seat at the maximum pressure
indicated, re-lubricate and try again.
When inflating the tire for mounting pressures up to 20 psi (1.38 bar)
greater than the maximum pressure on the tire sidewall, the following
precautions must be taken to protect the person mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 ft (3.66 m) away from the tire wheel
assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi (1.38 bar) greater than the
maximum pressure, a Ford dealer or other tire service professional
should do the mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 ft (3.66 m) away from the tire
wheel assembly.
Your vehicle is equipped with tires designed to provide a safe ride and
handling capability.

POLICE TIRES
Wheel rims - police
To withstand the demands placed on vehicles driven under heavy duty
service conditions, Ford Motor Company installs heavy duty steel wheels.
Tires - police
Tires (including the spare) are speed-rated radials for police use. Use
only the recommended tire size and speed ratings.
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 many 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.
Tires - long term 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, it should be
moved 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.

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 TPMS
Note:Each road tire and full-size
spare is equipped with a tire
pressure sensor located inside the
tire/wheel 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. Care must be taken
when changing the tire to avoid
damaging the sensor.
It is recommended that you always have your tires serviced by an
authorized dealer.
The tire pressure should be checked periodically (at least monthly) using
an accurate tire gauge. SeeInflating Your Tiresin 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 a new wheel and tire is installed
When one of your road tires is replaced by a new tire and wheel, the
TPMS sensor located in the new tire and wheel needs to be trained to
the vehicle.

TPMS training tools
The customer training tool, P/N 8C2Z-1A203-A, can be purchased from
any Ford dealer for training the system after maintenance has been
performed that requires system training. The tire pressure monitor
activation tool, P/N 204-363, is also available through the Rotunda
catalog. For either tool, follow the training instructions as outlined below.
TPMS sensor training procedure
Note:To reduce the chances of interference from another vehicle, TPMS
training should be performed at least three feet (one meter) away from
another Ford Motor Company vehicle undergoing the TPMS training
procedure at the same time.
Note: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 chirp indicates the need to repeat the procedure.
TPMS training procedure
Note:It is recommended that you read the entire procedure before
attempting.
Note:To enter the training mode, Steps 1–6 MUST be completed within
60 seconds.
1. Place the ignition in the off position and keep the key in the ignition.
2. Press and release the brake pedal.
3. Cycle the ignition from off to on three times ending in the on position
- DO NOT start the engine.
4. Press and hold the brake pedal for two seconds, then release.
5. Turn the ignition to off - DO NOT remove the key.
6. Cycle the ignition from off to on three times ending in on - DO NOT
start the engine.
If the training mode has been entered successfully, the horn will sound
once, the TPMS indicator will flash, and the information display will show
TRAIN LF TIRE.
If after repeated attempts to enter the training mode, the horn does not
sound, the TPMS indicator does not flash, and the information display
does not show TRAIN LF TIRE, seek service from your authorized
dealer.

How temperature affects your tire pressure
The tire pressure monitoring system (TPMS) monitors tire pressure in each
pneumatic tire. While driving in a normal manner, a typical passenger tire
inflation pressure may increase approximately 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 approximately 3 psi (21 kPa) for a drop of 30°F
(17°C) in ambient temperature. This lower pressure value may be detected
by the TPMS as being significantly lower than the recommended inflation
pressure and activate the TPMS 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 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:The use of tire sealants may damage your tire
pressure monitoring system and should not be used. However, if
you must use a sealant, the TPMS sensor and valve stem on the wheel
must be replaced by an authorized Ford dealer.
WARNING:SeeTire Pressure Monitoring Systemin this
chapter for important information. If the tire pressure monitor
sensor becomes damaged, it will no longer function.
Note:The tire pressure monitoring system indicator light will illuminate
when the spare tire is in use until the spare’s TPMS sensor is trained.
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 TPMS sensors, seeTire Pressure Monitoring Systemearlier in
the chapter. During repairing or replacing of the flat tire, have the
authorized dealer inspect the TPMS sensor for damage.
