Driving the 4 (start) position, the engine may continue cranking for up to 10 seconds or until the vehicle starts. Note: Cranking may be stopped at any time by turning the key to the off position. 3. After idling for a few seconds, release the parking brake, apply the brake, shift into gear and drive. Note: If the engine does not start on the first try, turn the key to the off position, wait 10 seconds and try Step 2 again. If the engine still fails to start, press the accelerator to the floor and try Step 2 again, keeping the accelerator on the floor until the engine begins to accelerate above cranking speeds; this will allow the engine to crank with the fuel shut off in case the engine is flooded with fuel. Your vehicle may have remote start capability. Refer to Remote entry system in the Locks and Security chapter. Cold weather starting (flexible fuel vehicles only) The starting characteristics of all grades of E85 ethanol make it unsuitable for use when ambient temperatures fall below 0°F (-18°C). Consult your fuel distributor for the availability of winter grade ethanol. As the outside temperature approaches freezing, ethanol fuel distributors should supply winter grade ethanol (same as with unleaded gasoline). If summer grade ethanol is used in cold weather conditions, 0°F to 32°F (-18°C to 0°C), you may experience increased cranking times, rough idle or hesitation until the engine has warmed up. You may experience a decrease in peak performance when the engine is cold when operating on E85 ethanol. Do not crank the engine for more than 10 seconds at a time as starter damage may occur. If the engine fails to start, turn the key to off and wait 30 seconds before trying again. Do not use starting fluid such as ether in the air intake system. Such fluid could cause immediate explosive damage to the engine and possible personal injury. If you should experience cold weather starting problems on E85 ethanol, and neither an alternative brand of E85 ethanol nor an engine block heater is available, the addition of unleaded gasoline to your tank will improve cold starting performance. Your vehicle is designed to operate on E85 ethanol alone, unleaded gasoline alone, or any mixture of the two. See Choosing the right fuel in the Maintenance and Specifications chapter for more information on ethanol. 268 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
