Driving 3. Turn the key to 3 (on) without turning the key to 4 (start). Some warning lights will briefly illuminate. See Warning lights and chimes in the Instrument Cluster chapter for more information regarding the warning lights. Starting the engine 1. Turn the key to 3 (on) without turning the key to 4 (start). If there is difficulty in turning the key, rotate the steering wheel until the key turns freely. This condition may occur when: • the front wheels are turned. • a front wheel is against the curb. 2. Turn the key to 4 (start), then release the key as soon as the engine begins cranking. Your vehicle has a computer assisted cranking system that assists in starting the engine. After releasing the key from 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. 264 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
