Crown Victoria Severe Duty TRANSMISSION The police vehicle has a unique high-performance powertrain including transmission and an aluminum driveshaft, which is designed for maximum vehicle performance. Due to the nature of this powertrain, some powertrain noise may be present. Driving in the overdrive cancel mode for prolonged periods at high speeds will deteriorate performance and may cause extensive engine damage. Crown Victoria police vehicles are designed to operate in the (Overdrive) gear selector position while in pursuit. Optimum performance (Overdrive). Operation in the overdrive cancel will be obtained in mode should only be used in situations noted in this publication. WARNING: Under no circumstances should the aluminum driveshaft be replaced with a steel driveshaft. Doing so will adversely affect vehicle operation which could lead to personal injury. POWERTRAIN OVERSPEED PROTECTION The powertrain control module (PCM) includes logic to electronically prevent powertrain overspeed in any transmission selector position. IDLE METER Your vehicle may be equipped with an idle meter to indicate how much time the vehicle is idling in P (Park) or N (Neutral). The meter is incorporated with the vehicle odometer. Pressing the odometer-reset button once will display the trip odometer (miles followed by a ЉTЉ for trip odometer). Pressing the odometer-reset button a second time will display the idle meter (hours followed by an ЉhЉ for hours). The idle meter only accumulates time when the vehicle is in P (Park) or N (Neutral). Displayed time is cumulative for the vehicle. It cannot be reset to zero. Police/Fleet vehicles often experience long periods of idling, during which engine oil will continue to break down but mileage is not accumulated on the odometer. To assist fleet managers in maintaining proper oil change intervals, the idle meter will help determine when an oil change is required. For every hour that the vehicle idles, it has accumulated the equivalent of approximately 33 miles (53 km) of driving. Using the combination of the vehicle odometer and idle meter allows the fleet manager to better determine when the oil needs to be changed. 270 2010 Crown Victoria (cro) Owners Guide, 2nd Printing USA (fus)
