TPMS
malfunctionIf your tires are properly inflated
and your spare tire is not in use
and the TPMS warning light still
flashes, have the system inspected
by your 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 (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 THE TIRES
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.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire pressure monitoring system
(TPMS)in theTires, Wheels and Loadingchapter. 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 TPMS sensor for
damage.
WARNING:The use of tire sealants may damage your tire
pressure monitoring system (TPMS) 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:Refer toTire pressure monitoring system (TPMS)
in theTires, Wheels and Loadingchapter for important
information. If the tire pressure monitor sensor becomes damaged, it
will no longer function.
Dissimilar spare tire/wheel 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 tire/wheel, 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 tire/wheel 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.

WHEELS/TIRES/BRAKES
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.
Training the tire pressure monitoring system (TPMS)
All Crown Victorias are equipped
with a tire pressure monitoring
system (TPMS) that illuminates a
low tire pressure warning light on
the instrument cluster when one or
more of your tires is significantly under-inflated.

Each road tire, as well as the spare,
is equipped with a tire pressure
sensor fastened to the inside of the
rim, opposite (180 degrees) from
the valve stem. The signal from each
transmitter is digitally unique to
avoid interference from transmitters
on other nearby vehicles.
Note:The spare has a TPMS
sensor, but is not programmed to
the module.
Changing tires with a TPMS
Care should be taken avoid damaging the sensor and band during
mounting or dismounting. Please refer to the Crown VictoriaWorkshop
Manualfor the complete mount and dismount procedure. This is critical,
as the procedure is different from previous model years due to the
introduction of the TPMS.
When a new tire/wheel is installed,the TPMS sensor located in the
new tire/wheel needs to be “trained” to the vehicle.
TPMS training tools,such as P/N 8C2Z-1A203-A, can be purchased
from any Ford dealer for use by the driver or shop technician for training
the system after maintenance has been performed that requires system
training. The Tire Pressure Monitor Activation Tool, P/N 204-363, has
more functionality and is designed primarily for shop use. For either tool,
follow the training instructions as outlined below.
Note:This procedure is also included in the Crown VictoriaWorkshop
Manual.
TPMS reset tips:
•To reduce the chances of interference from another vehicle, the TPMS
reset procedure should be performed at least three feet (one meter)
away from another Ford Motor Company vehicle undergoing the TPMS
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 chirp indicates the need to repeat the procedure.
TPMS reset procedure
Note:It is recommended that you read the entire procedure before
attempting.
Note:To enter the reset 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 NOTstart the engine.

4. Press and hold the brake pedal
for two seconds, then release.
5. Turn the ignition to off -DO
NOTremove the key.
6. Cycle the ignition from off to on three times ending in on -DO NOT
start the engine.
If the reset mode has been entered successfully, the horn will sound
once, and the TPMS indicator
will flash.
If after repeated attempts to enter the reset mode, the horn does not
sound, and the TPMS indicator
does not flash, seek service from
your authorized dealer.

7. Train the TPMS sensors in the tires using the following TPMS reset
sequence starting with theleft front tirein the following clockwise
order:
•Left front (Driver’s side front tire)
•Right front (Passenger’s side front tire)
•Right rear (Passenger’s side rear tire)
•Left rear (Driver’s side rear tire)
8.Left front tire:Place the TPMS reset tool against the left front tire
where the tire meets the rim, opposite from the valve stem (1) as shown.
This is where the sensor is located inside the rim.
Both tools, the TPMS training tool (part number 8C2Z-1A203-A)
or the Tire Pressure Monitor Activation Tool (part number
204-363), must be held against the tire sidewall opposite the
valve stem as illustrated. For the TPMS training tool, the device
should be held as illustrated, with the arrow on the tool pointing
towards the rim; do not use the tool with the arrow pointing away
from the rim as it may not activate the sensor.
9. Press and release the activation button while holding either tool to the
side wall until the horn sounds. The horn will sound once within
approximately 10 seconds to indicate the process was successful.
Note:
•If a double horn chirp is heard, repeat the procedure. If a single horn
chirp is not heard, move the vehicle to rotate the wheels at least a
14-turn and repeat the procedure starting with Step 1.
