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 Ҁ10˚F (Ҁ23˚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 more quickly. 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 leave it plugged in all night to start your vehicle the following morning. What To Do If The Engine Does Not Start Fuel Pump Shut-Off Switch If the engine cranks but does not start or does not start even after a small collision, the fuel pump shut-off switch may have been activated. The shut-off switch is a device intended to stop the fuel pump when your vehicle has been involved in a substantial jolt. Refer to the Roadside emergencies section for more information. 214
