Driving Note: If the engine does not start on the first try, turn the key to OFF, wait 10 seconds and try again. If the engine still fails to start, press the accelerator to the floor and try again; this will allow the engine to crank with the fuel shut off in case the engine is flooded with fuel. If your vehicle has an automatic transmission, it will have a computer assisted cranking system. This feature assists in starting the engine. If the ignition key is turned to the 4 (START) position, and then released when the engine begins cranking, the engine may continue cranking for up to 10 seconds or until the vehicle starts 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 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 block heater system is most effective when outdoor temperatures reach below 0°F (-18°C). Failure to follow engine block heater instructions could result in property damage or physical harm. To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters. 258 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
