150 Starting and Stopping the Engine • Make sure your vehicle is parked in a clean area, clear of combustibles. • Make sure the heater, heater cord and extension cord are firmly connected. • Check for heat anywhere in the electrical hookup once the system has been operating for approximately 30 minutes. • 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. • Keep plug terminals clean and free of dirt and corrosion. • 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 before use. To clean them, use a dry cloth. 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. 2014 05+ Mustang (197) Owners Guide gf, 2nd Printing, May 2013 USA (fus)
