Warning
Improper use of the heater cord or an
extension cord can damage the cord and
may result in overheating and fire.

Plug the cord into a three-prong
electrical utility receptacle that is

function. An ungrounded outlet could
cause an electric shock.

15 amp-rated extension cord if needed.
Failure to use the recommended
extension cord in good operating
condition, or using a damaged heater
or extension cord, could make it
overheat and cause a fire, property
damage, electric shock, and injury.

the vehicle. Possible heater cord and
thermostat damage could occur.
