Starting RWARNING Extended idling at high engine speeds can produce very high temperatures in the engine and exhaust system, creating the risk of fire or other damage. RWARNING Do not park, idle, or drive your vehicle in dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, which can start a fire. If you consistently start your vehicle in subzero temperatures, use an engine block heater (if your vehicle has this option). Engine Block Heater (If equipped) Engine block heaters are strongly recommended if you live in a region where temperatures reach -10˚F (-23˚C) or below. An engine block heater warms the engine coolant, which improves starting, warms up the engine faster, and allows the heater-defrost system to respond quickly. To turn the heater on, simply plug it into a grounded 110-volt outlet. Ford recommends that you use a 110-volt circuit that is protected by a ground fault circuit interrupter. RWARNING To prevent electrical shock, do not use your heater with ungrounded electrical systems or two-pronged (cheater) adapters. For best results, plug the heater in at least three hours before you start your vehicle. Using the heater for longer than three hours will not damage the engine, so you can plug it in at night to start your vehicle the following morning. 121
