Mercury Grand Marquis (2011 year). Manual

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 the Police Interceptor Modifier Guide for 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 the Crown 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.

Crown Victoria Severe Duty

276

2011 Crown Victoria (cro)
Owners Guide, 3rd Printing
USA (fus)

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 Victoria Workshop
Manual for 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 Victoria Workshop
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.

Crown Victoria Severe Duty

277

2011 Crown Victoria (cro)
Owners Guide, 3rd Printing
USA (fus)

• 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 NOT start the engine.

Crown Victoria Severe Duty

278

2011 Crown Victoria (cro)
Owners Guide, 3rd Printing
USA (fus)

7. Train the TPMS sensors in the tires using the following TPMS reset
sequence starting with the left front tire in 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

⁄

-turn and repeat the procedure starting with Step 1.

Crown Victoria Severe Duty

280

2011 Crown Victoria (cro)
Owners Guide, 3rd Printing
USA (fus)

• If the horn does not sound while attempting to reset any wheel, seek

service from your authorized dealer.

10. Perform Steps 8 and 9 on the right front tire, right rear tire and
finally the left rear tire. Training is complete after the horn sounds for
the last tire trained (left rear tire).

Turn the ignition to off. If two short horn beeps are heard, the reset
procedure was unsuccessful and must be repeated.

If after repeating the procedure and two short beeps are heard when the
ignition is turned to off, seek assistance from your authorized dealer.

Brakes - police

The police vehicle is equipped with heavy duty front disc brake pads to
meet the varying demands of different police service for fade resistance
and other performance requirements.

The police vehicle has standard anti-lock brakes and may be equipped
with traction control.

Brake fluid maintenance

Police pursuits involving hard braking result in very high temperatures in
the brake system, including the brake fluid. Over time, repeated
exposure to high brake temperatures can degrade brake fluid, potentially
reducing its boiling point. A lower boiling point could cause long brake
pedal travel and a loss of braking confidence during subsequent pursuit
driving. Ford recommends that police fleets replace the brake fluid at
every brake pad service interval. Brake fluid may be replaced more
frequently on vehicles involved in frequent high-speed pursuits with
heavy brake usage.

INTERIOR

Heavy duty seats - police

The front seat assemblies, including the seat adjustment mechanisms and
supports, are ruggedly designed and ensure working comfort. An
anti-stab plate is integrated into the seat back to reduce the risk of
officer injury. An adjustable power lumbar system is standard on the
driver’s seat.

Seat belt extenders

Some police departments have begun employing the use of seat belt
extenders to make the practice of buckling and unbuckling seat belts
easier for officers wearing hip mounted radios, side arms, etc.

Crown Victoria Severe Duty

281

2011 Crown Victoria (cro)
Owners Guide, 3rd Printing
USA (fus)

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 is

⫾2 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]

Crown Victoria Severe Duty

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 a Police Interceptor Modifier Guide to 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.

Trunk Pack™ and trunk loading

WARNING: Ford recommends that police equipment be both
secured and laterally aligned. Hard, stiff or sharp objects,

especially when not secured or properly located, pose a risk to the fuel
tank and back seat occupants in the event of a high speed rear impact.
After-market organizers that do not adequately deform in rear-impacts
can themselves become injury-producing objects. When locating,
securing and mounting police equipment, please review the

⬙Trunk

Equipment Mounting Guide,

⬙ available on the www.cvpi.com website,

which provides recommended fastener mounting types and locations.

WARNING: Following the trunk packing considerations, also on
the www.fleet.ford.com website, is the most meaningful method

of reducing risk. If your department practice is inconsistent with the
Trunk Packing Considerations, then Ford suggests that you consider
purchasing an optional drop-in Trunk Pack™ to further reduce the risk
of injury resulting from police equipment pushing forward into the
back seat and/or fuel tank in the event of a high-speed rear impact.
The Trunk Pack™ provides more flexibility to officers transporting
police equipment than the trunk packing considerations.

To improve trunk packing by police agencies, Ford has made the
following items available:
• Trunk Pack™ – a drop-in box with a tough plastic shell made of high

density Polyethylene (HDPE). It both aligns police equipment laterally
in the trunk and utilizes a puncture resistant lining on the forward
side of the box to reduce the risk of police equipment penetrating into
the fuel tank and/or back seat in high-speed rear impacts.

• Trunk Equipment Mounting Guide – an outline pattern with

recommended fastener mounting locations in the trunk. The guide can
be found in the Police Interceptor Modifier Guide and on the
Internet at www.fleet.ford.com.

• Trunk packing considerations – the following guidelines are offered to

reduce the risk of unique police equipment items pushing through the
fuel tank and/or back seat (see our www.fleet.ford.com website for
more details).

Trunk packing considerations

A slogan has been developed to increase police agency awareness of the
importance of trunk packing.

Equipment categories and placement

It is recognized that a wide variety of equipment is carried in the trunks of
police vehicles as noted above. This section addresses the inherent risks of
various types of equipment in the event of a high-speed rear impact.

This information is divided into three categories:
• Carrying not recommended
• Carry with caution
• Low risk items

WARNING: Carrying not recommended – The following
items have been observed in police vehicles and should

not be transported in a vehicle trunk – containers with gasoline,
loose ammunition, loose flares, loose fire extinguisher(s), loose 4-point
lug wrench, loose crowbars, loose axes and other loose equipment with
potential puncture capability in high speed rear end collisions.

Carry with caution – These items will require special packing or
mounting consideration and possibly use of the Trunk Pack™ as an
additional level of safety. Examples include (with proposed orientation):
fire extinguisher (fixed), lug wrench 4–point (fixed - vertical), rolotape
measuring wheel (fixed - vertical), safety flares (lateral orientation – in a
container), stop stick (lateral - mount on deck lid inner panel), shovel
(lateral - place at rear of trunk), shotgun and rifle (lateral - store in
case), baton (lateral - place at rear of trunk), ammunition (container).
Flares should be placed in a protective storage container (preferably soft
sided plastic). Flares with spikes attached should be laterally oriented in
the trunk area.

1. Spare tire special considerations – The safest location for the
spare tire, jack and lug wrench is the production location on the forward
package shelf above the rear axle. If unable to mount there, the next
safest location for the spare tire is mounted vertically inside the Trunk
Pack™ using the J-bolt attachment device provided with the Trunk
Pack™. The jack and lug wrench should be stored in the rearward
compartment of the Trunk Pack™.

Crown Victoria Severe Duty

285

2011 Crown Victoria (cro)
Owners Guide, 3rd Printing
USA (fus)

2. Electronic Equipment – The safest location for the electronic
equipment is on the trunk forward package shelf. Some equipment can
be mounted in the side shelf areas, but it must not protrude into the fuel
tank area in a crash (noted in Trunk Equipment Mounting Guide). The
optional Complete Police Prep Package is available to facilitate packaging
of electronic components with a sliding tray for the forward package
shelf and side compartments in the right and left shelf area. All
equipment should be located and mounted using the

⬙Trunk Equipment

Mounting Guide

⬙ for proper positioning of fasteners. This guide can be

accessed on the www.fleet.ford.com website. The sliding tray can also be
used, depending on size, to properly store parts with rigid and sharp
edges.

3. Ammunition – The safest location for ammunition is the forward
package shelf and on the side shelves. It is recommended that a plastic
storage container be utilized and mounted using the

⬙Trunk Mounting

Equipment Guide

⬙ for proper fastener locations. It is also recommended

that ammunition remain in the purchased container and be placed in a
safe storage container.

Low risk items – These items are soft in feel and pose a low risk of
trunk wall, rear seat area, and fuel tank puncture. Examples are: a soft
camera case, biohazard kit in plastic boxes, gloves, safety rope, tow
strap, traffic cones & sleeves, rain gear, riot gear (soft), emergency
blankets, bullet resistant vest, tie straps, cloth tape, garment bags, first
responder kit, Res-Q-Flo mask (placed in garment bag), fuses (plastic
container), briefcase, notebooks, spray bottles, helmet, and jumper
cables. It is not essential but recommended that the Trunk Pack™ can
be considered for organization of low risk items, especially if mixed with
“Carry With Caution” items.

BODY

Fire suppression system (if equipped)

Your vehicle may be equipped with an optional fire suppression system.
The fire suppression system is designed to help reduce the risk of injury
in high-speed rear impacts. The fire suppression system deploys
chemicals designed to slow the spread of fire or potentially extinguish a
fire, thereby providing more time for occupants to escape from a crashed
vehicle.

Crown Victoria Severe Duty

286

2011 Crown Victoria (cro)
Owners Guide, 3rd Printing
USA (fus)

The fire suppression system is mounted beneath the vehicle and
attached to the frame above and forward of the fuel tank and rear axle.
The fire system control module is mounted inside the passenger
compartment centered underneath the rear seat cushion. The system is
designed to deploy automatically after sensing a high-speed/high-energy
rear end impact.

There is a covered manual activation switch mounted in a console on the
headliner between the visors that can be used by vehicle occupants to
manually deploy the system. The fire suppression system can be
manually deployed any time the key or engine is turned on by pushing
the button underneath the cover. The button can be accessed three
ways:

1. Pushing on the cover will release the cover latch, allowing the door to
swing open and expose the button;

2. The cover can be pulled open;

3. A firm strike on the cover (about 20 lb–ft [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.

Crown Victoria Severe Duty

Owners Guide, 3rd Printing
USA (fus)

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 vehicle “fireproof” because it is equipped
with a fire suppression system.

Ballistic door panels (if equipped)

Your vehicle may be equipped with ballistic door panels on one or both
of the front doors. Doors equipped with a ballistic panel are marked with
a sticker on the interior door trim panel above the door handle indicating
“BALLISTIC PANEL”. Otherwise, doors with ballistic panels are visually
indistinguishable from standard doors. The ballistic panels are designed
to act as a shield for the officer at the scene of an altercation.

The door panels meet National Institute of Justice (NIJ) Level III
protection requirements. NIJ is the research, development, and
evaluation agency within the U. S. Department of Justice. The panels
have been tested and certified by a NIJ approved ballistic testing
laboratory, in accordance with the methodology included in NIJ Standard
0108.01 and Los Angeles Police Department (LAPD) Standard MTD
05-01E.
