1996 Ford Crown Victoria Owner's Manual - Page 66

A problem is indicated if the fuel gauge bar graph displays only the top two and bottom two bars and the message center display for Distance To Empty or Fuel Remaining functions display the letters "CO" or "CS". If this happens, contact your dealer for service as soon as possible. Speedometer The speedometer tells you how many miles (kilometers) per hour your vehicle is moving. It indicates the speed up to 120 mph or up to 195 km/h. You can press the E/M (English/Metric) button located just below the message center display to show the speed you are going in either miles per hour or kilometers per hour. Odometer The odometer tells you the total number of miles or kilometers your vehicle has been driven. If the cluster is replaced, and the accumulated mileage on the odometer is unknown, the replacement cluster will have the circled "S" illuminated with zero miles on the odometer. If the actual vehicle mileage can be verified, then an authorized service center can program the actual mileage into the odometer of the replacement cluster. The actual mileage (if known) or an estimated mileage (if unknown) is shown on a label affixed on the door pillar. 73
