Driving style — good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
•Smooth, moderate operation can yield up to 10% savings in fuel.
•Steady speeds without stopping will usually give the best fuel
economy.
•Idling for long periods of time (greater than one minute) may waste
fuel.
•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between the top gears occurs. Unnecessary
shifting of this type could result in reduced fuel economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.

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 the Tire Pressure Monitoring
System (TPMS) that illuminates a
low tire pressure telltale on the
instrument cluster when one or
more of your tires is significantly under-inflated.

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™.
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 theTrunk Equipment
Mounting Guidefor 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.
