Driving See Choosing the right fuel in the Maintenance and Specifications chapter for more information on ethanol. Hot weather starting (flexible fuel vehicles only) If you are experiencing a rough or rolling idle after start-up with the outside temperature above 80°F (27°C), the idle should improve within 10 to 30 seconds. If the problems persist below this temperature, see your authorized dealer. 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 Carbon monoxide is present in exhaust fumes. Take precautions to avoid its dangerous effects. If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Important ventilating information If the engine is idling while the vehicle is stopped for a long period of time, open the windows at least one inch (2.5 cm) or adjust the heating or air conditioning to bring in fresh air. ENGINE BLOCK HEATER (IF EQUIPPED) An engine block heater warms the engine coolant which aids in starting and heater/defroster performance. Use of an engine block heater is strongly recommended if you live in a region where temperatures reach -10°F (-23°C) or below. For best results, plug the heater in at least three hours before starting the vehicle. The heater can be plugged in the night before starting the vehicle. To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters. 241 2007 F-150 (f12) Owners Guide (post-2002-fmt) USA (fus)
