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]
