Starting and Stopping the Engine • Make sure the system is unplugged and properly stowed before driving your vehicle. Make sure the protective cover seals the prongs of the block heater cord plug when not in use. Make sure the heater system is checked for proper operation before winter. • Using the Engine Block Heater Make sure the receptacle terminals are clean and dry prior to use. Clean them with a dry cloth if necessary. The heater uses 0.4 to 1.0 kilowatt-hours of energy per hour of use. The system does not have a thermostat. It achieves maximum temperature after approximately three hours of operation. Using the heater longer than three hours does not improve system performance and unnecessarily uses electricity. 155 MKZ (CC9)
