WARNING
  Failure to follow engine block heater instructions could result in property damage or serious personal injury.
  Do not use your heater with ungrounded electrical systems or two-pronged adapters. There is a risk of electrical shock.

Note:  The heater is most effective when outdoor temperatures are below 0°F (-18°C).
The heater acts as a starting aid by warming the engine coolant. This allows the climate control system to respond quickly. The equipment includes a heater element (installed in the engine block) and a wire harness. You can connect the system to a grounded 120-volt AC electrical source.
We recommend that you do the following for a safe and correct operation:
  • Use a 16-gauge outdoor extension cord that is product certified by Underwriter’s Laboratory (UL) or Canadian Standards Association (CSA). This extension cord must be suitable for use outdoors, in cold temperatures, and be clearly marked Suitable for Use with Outdoor Appliances. Do not use an indoor extension cord outdoors. This could result in an electric shock or become a fire hazard.
  • Use as short an extension cord as possible.
  • Do not use multiple extension cords.
  • Make sure that when in operation, the extension cord plug and heater cord plug connections are free and clear of water. This could cause an electric shock or fire.
  • 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 heater system is checked for proper operation before winter.
Using the Engine Block Heater
The engine block heater plug is located in a housing in the left fog lamp bezel. Open the hinged, circular door and 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 will achieve maximum temperature after approximately three hours of operation. If you use the heater longer than three hours, this will not improve system performance and will use unnecessary electricity.
