Running out of fuel Avoid running out of fuel because this situation may have an adverse effect on powertrain components. If you have run out of fuel: • You may need to cycle the ignition from OFF to ON several times after refueling to allow the fuel system to pump the fuel from the tank to the engine. On restarting, cranking time will take a few seconds longer than normal. • Normally, adding 1 gallon (3.8L) of fuel is enough to restart the engine. If the vehicle is out of fuel and on a steep grade, more than 1 gallon (3.8L) may be required. indicator may come on.

ESSENTIALS OF GOOD FUEL ECONOMY Measuring techniques Your best source of information about actual fuel economy is you, the driver. You must gather information as accurately and consistently as possible. Fuel expense, frequency of fill-ups or fuel gauge readings are NOT accurate as a measure of fuel economy. We do not recommend taking fuel economy measurements during the first 1,000 miles (1,600 km) of driving (engine break-in period). You will get a more accurate measurement after 2,000 miles-3,000 miles (3,000 km-5,000 km). Filling the tank The advertised fuel capacity of the fuel tank on your vehicle is equal to the rated refill capacity of the fuel tank as listed in the Maintenance product specifications and capacities section of this chapter. 259 2008 05+ Mustang (197) Owners Guide (post-2002-fmt) USA (fus)
