Severe duty equipment
Seat Belt Extenders
A common complaint from police officers is the difficulty of buckling and
unbuckling the seat belt due to the location of a vehicle equipment
console and/or equipment being worn on the hip, such as a side arm.
The length of the buckle in relation to these other components can make
the buckle difficult to find and make connection of the seat belt
challenging. As a result, some police departments have begun employing
the use of seat belt extenders to make the practice of buckling and
unbuckling of seat belts easier for the driver.
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 from an imaginary center line of the occupant's body.
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 (
"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.
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]
