Crown Victoria Severe Duty 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 Ϯ2 mph ( Ϯ3 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) Your 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. 281 2010 Crown Victoria (cro) Owners Guide, 2nd Printing USA (fus)
