Driving If the engine fails to start using the preceding instructions (flexible fuel vehicles only) 1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then crank the engine. 2. When the engine starts, release the key, then gradually release the accelerator pedal as the engine speeds up. If the engine still fails to start, repeat Step 1. Guarding against Exhaust Fumes WARNING: If you smell exhaust fumes inside your vehicle, have this checked immediately. Do not drive your vehicle if you smell exhaust fumes. Carbon monoxide is present in exhaust fumes. Take precautions to avoid its dangerous effects. Important Ventilating Information If you stop your vehicle and leave the engine idling for long periods of time, we recommend that you do one of the following: • Open the windows at least one inch (2.5 centimeters). • Set your climate control to outside air. ENGINE BLOCK HEATER (IF EQUIPPED) An engine block heater warms the engine coolant which aids in starting and allows the heater/defroster system to respond quickly. If your vehicle is equipped with this system, your equipment includes a heater element which is installed in your engine block and a wire harness which allows the user to connect the system to a grounded 120 volt A/C electrical source. The engine block heater plug can be located through the center opening of the lower front bumper assembly. The block heater system is most effective when outdoor temperatures reach below 0°F (-18°C). For flexible fuel vehicles, if operating with E85 ethanol, an engine block heater must be used if ambient temperature is below 0°F (-18°C). See Cold weather starting earlier in this chapter for more information on starting with ethanol. WARNING: Failure to follow engine block heater instructions could result in property damage or physical injury. 269 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
