Driving 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. Using the engine block heater (if equipped) If your vehicle is factory-equipped with an engine block heater, a rubber cap/plug assembly will be visbly attached to the grille on the front of the vehicle. For factory equipped, this assembly is loose shipped in-vehicle for dealership installation. If not factory-equipped, the engine block heater can be purchased through dealership accessories. Replacement rubber caps are available through the dealer, 3L1Z-6E088-AA. 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 plug the heater in, remove the cap from the plug and insert the plug into a 110 volt grounded outlet. Be sure to re-attach the cap onto the plug when the heater is not in use. Note: Make sure you disconnect the cap from the plug when opening the hood. To reduce the risk of electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters. Guarding against exhaust fumes Carbon monoxide is present in exhaust fumes. Take precautions to avoid its dangerous effects. 234 2004 Navigator (nav) Owners Guide (post-2002-fmt) USA English (fus)
