Crown Victoria Severe Duty 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. 281 2011 Crown Victoria (cro) Owners Guide, 1st Printing USA (fus)
