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. NOTE: Be sure to disconnect the engine block heater before driving your vehicle. Guarding Against Exhaust Fumes Carbon monoxide, although colorless and odorless, is present in exhaust fumes. Take precautions to avoid its dangerous effects. RWARNING Do not start your vehicle in a closed garage or other enclosed area. Never sit in a stopped vehicle for more than a short period of time with the engine running. Exhaust fumes are toxic. See Guarding Against Exhaust Fumes in this chapter for more instructions. RWARNING If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. 51
