Running out of fuel
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
•Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.
•The service engine soon
indicator may come on. For more
information on the service engine soon
indicator, refer to
Warning lights and chimesin theInstrument Clusterchapter.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend taking
fuel economy measurements during the first 1,000 miles (1,600 km) of
driving (engine break-in period). You will get a more accurate
measurement after 2,000 miles–3,000 miles (3,000 km–5,000 km).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theMaintenance
product specifications and capacitiessection of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.

Headlight flashers (wig-wags) - police
An interfacing connector is provided on the headlight circuit for use of
the headlights as alternating flashers (wig-wags). The connector is
located in front of the radiator. A protective cap is attached to prevent
contaminants from entering the connector when a wig-wag module is not
installed. When installing a headlight flasher (wig-wag) module, remove
the connector and tape it to the wigwag module harness. This will ensure
that the cap is available to be reattached if the wig-wag module is
removed. For additional information, refer to theCrown Victoria
Wiring Diagram Manual.
If your vehicle is equipped with one of the optional Police Interceptor
Equipment Packages, the connector will already be used by the supplied
wig-wag module that comes with the option package.
Note:Use of the wig-wag feature overrides normal operation of the high
beam headlights, including flash-to-pass. However, the low beam
headlights will remain on and unaffected.
HEAVY-DUTY SUSPENSION - POLICE
This option includes certain heavy-duty components that contribute to
the vehicle’s stability and road handling capability under extremes of
operation. The police vehicle has a heavy duty steering gear, extra
control shock absorbers and heavy-duty front and rear stabilizer bars.
COOLERS
It is strongly recommended that auxiliary devices such as lights not be
installed at the grille. Such devices will reduce airflow through the grille
and could potentially impact the cooling system performance.
Oil cooler - police
The 4.6L engine has an engine oil cooler to maintain engine oil
temperatures.
Engine and transmission coolers
External transmission and power steering coolers are located behind the
grille and in front of the radiator. It is strongly recommended that
auxiliary devices such as lights and sirens not be installed in the air path
of these coolers as they will impact cooling system performance.

3. A firm strike on the cover (about 20 lbft [89 N•m] of force) will
deploy the system any time the key or engine is turned on.
In the event of a manual deployment, nozzles will deploy to near ground
level and the underbody of the vehicle will be covered with suppressant
fluid. The suppressant contains no hazardous materials (but may cause
minor skin or eye irritation) and can be readily cleaned up by flushing
the underbody with water (or soap and water). Manual deployment
should have no adverse affect on vehicle handling; however, caution
should be exercised in moving the vehicle as ground clearance will be
compromised by the deployed nozzles. Because of reduced ground
clearance, the vehicle should not be driven through an automatic car
wash with nozzles in the deployed condition.
The fire suppression system is a single use system - all major
components will have to be replaced in the event of a manual
deployment.
Figure A
The approved ISO symbol for fire suppression is shown in Figure A. This
symbol is printed on the manual activation switch and on the diagnostic
telltale on the instrument cluster.
The system automatically performs a diagnostic check self check and
momentarily lights the cluster lamp when the key is turned on. If the
diagnostic lamp stays on refer to the appropriate sections of the Ford
service manual for further diagnostic and service procedures.
The system is active any time the key or engine is turned on following
the diagnostic check.
The system has been designed and tested to withstand a 75 mph
(120 km/h) 50% off-set rear impact by Taurus-sized vehicle. However, in
some crashes, including very high-energy crashes, the fire suppression
system could be so damaged by the crash forces that it cannot deploy.
Like any vehicle component, the fire suppression system cannot
withstand any and all crashes. No vehicle can eliminate the risk of fires.
You should not consider the vehiclefireproofbecause it is equipped
with a fire suppression system.
