light Mercury Grand Marquis 1011 s Owners Manual

“Premium” unleaded gasoline is not recommended for vehicles designed
to use “Regular” unleaded gasoline because it may cause these problems
to become more pronounced. If the problems persist, see your
authorized dealer.
FFV engines
If you experience starting, rough idle or hesitation driveability problems
during a cold start, try a different brand of E85 fuel. If the driveability
problems continue, fill the vehicle with regular unleaded gasoline and
drive vehicle normally until gasoline is used. See your authorized dealer
if the problem persists.
Do not add aftermarket fuel additive products to your fuel tank. It
should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. These products have not been approved for your engine and
could cause damage to the fuel system. Repairs to correct the effects of
using an aftermarket product in your fuel may not be covered by your
warranty.
Many of the world’s automakers approved the World-Wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-Wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-Wide Fuel Charter.
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

Alternator - police
The high-output alternator provides 200 amperes of current to support
the high power requirements of modern police equipment. Output at idle
is approximately 130 amperes. Current demand by both the vehicle and
all energized police equipment in excess of this amount during vehicle
idling will place the electrical system into a discharge condition.
Electrical power management systems should be applied if necessary to
avoid discharging the battery.
Power distribution connector
Power for aftermarket equipment can be obtained from the power
distribution connector located under the glove compartment. This
connector contains several fused power feeds and inputs available for the
addition of accessories. The following tables show the circuits available
for equipment.

The mating connector is provided on the end of the power distribution
connector. The vehicle modifier can either purchase pins for the mating
connector and install them on the wires before they are inserted into the
connector, thereby avoiding any splicing, or purchase an optional power
pigtail for the interface. The power pigtail (P/N 14A411) plugs into the
power distribution connector and provides blunt cut wires ready for
splicing by the vehicle modifier.
See thePolice Interceptor Modifier Guidefor more details.
Rear power point - police
The rear power point is a battery access port for police auxiliary
equipment mounted in the trunk. It is capable of supplying 80 amps of
battery power. The front power distribution box (PDB) contains two
50 amp fuses, which protect the power point. Battery access is via two
studs contained in an enclosure, mounted in the trunk, on the right side
fender support. The terminal with the red wires is the battery positive,
and the terminal with the black wire is the ground. Remove both fuses in
the front PDB before removing the cover to the rear power point. Ensure
load devices can be turned off, and are switched off when reinserting
fuses.
WARNING:Under no circumstance should the rear power point
cover be removed without first pulling the two fuses in the front
power distribution box. Removing cover without pulling fuses could
result in an electrical hazard, and result in personal injury. Shut off
load devices before inserting fuses.

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.

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.

Seat belt extenders should never be worn when the lap strap will not
adjust snugly on the hips and/or when the intersection of the lap belt
and shoulder belt straps (measured along the lap strap) is less than six
(6) inches (15 cm) from an imaginary center line of the occupant’s body.
WARNING:Do not use extensions to change the fit of the
shoulder belt across the torso.
Calibrated speedometer - police
Deviations from true road speeds are minimized by a calibrated
speedometer head which gives both miles-per-hour (0–140 mph) and
kilometer-per-hour (0–222 km/h) readings. The speedometer head
assembly accuracy is2 mph (3 km/h) over the entire range (at 70°F
[21°C]). The “certified calibration” applies to the head assembly only and
does not apply to the indicated speed of the system, which is affected by
variations in vehicle loading, tire inflation pressures, tire rolling radii and
driveline ratios.
Red/White map light - police (if equipped)
The police vehicle may be equipped with a red/white map light located in
the headliner between the driver and front seat passenger. A
three-position switch provides either white or night-vision red options.
When the rocker switch is in the center position, the lamp is off.
Pressing the left side (white dot) makes the lamp operate in the white
light mode. Pressing the right side (red dot) makes the lamp operate in
the night-vision red mode.
Mobile communication systems
The Federal Communications Commission regulates the use of mobile
communication systems (such as two-way radios, telephones and theft
alarms) that are equipped with radio transmitters. If you install this
equipment in your vehicle, you should comply with those rules and a
qualified technician should install the equipment. Ford Motor Company
vehicles are in compliance with FCC regulations (CFR 47 Part 15) and
SAE J551d for radiated electromagnetic emissions.
Mobile communication systems may harm the operation of your vehicle,
particularly if they are not properly designed for automotive use or not
properly installed. For example, when operated, such systems may cause
the engine to stumble or stall and may affect 4R70W transmission
operation. In addition, such systems may themselves be damaged or their
operation affected by operating your vehicle. (Citizen band [CB]

transceivers, garage door openers and other transmitters whose power
output is 5 watts or less will not ordinarily affect your vehicle’s
operation.)
Because we have no control over the installation, design or manufacture
of such systems, Ford cannot assume responsibility for any adverse
effects or damage that may result if you use this equipment.
Malfunction of aftermarket electronic equipment should be resolved by
the equipment manufacturer.
Aftermarket equipment installation
Ford has developed aPolice Interceptor Modifier Guideto assist the
vehicle modifier in safely installing police equipment into the vehicle.
The guide provides detailed information on the location of key vehicle
components that must be untouched and warnings for other areas where
caution must be exercised. The Modifier Guide is available for
downloading, free of charge, from www.fleet.ford.com.
When installing aftermarket equipment, avoid using fasteners that are too
long for the application or are in an area which might damage vehicle
components, including wiring, brake lines, fuel tank and lines, powertrain
components, exhaust system and suspension.
Also, do not make electrical connections to vehicle electrical systems not
specifically designed for aftermarket equipment installations. Refer to the
“Wiring Diagram Manual” for electrical system information.
Do not install any components into the powertrain control module
(PCM) or PCM harness. Connecting into this system may affect engine
and transmission operation.
As an example: connection of aftermarket electrical equipment into the
brake light circuit or any other circuit which is connected to the PCM,
anti-lock brake computer, airbag system or any other vehicle system
which will cause vehicle malfunction.
WARNING:Contact during a crash with aftermarket equipment
in a vehicle can result in a personal injury.
WARNING:Installation of prisoner barriers may increase the
risk of injury to front seat occupants if the vehicle is impacted
from the rear at high speeds. This risk should be balanced, by the law
enforcement agency, against the risk of injury to the Officer associated
with prisoner transport.
