To Use the Engine Heater

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
protected by a ground fault detection
function. An ungrounded outlet could
cause an electric shock.
Use a weatherproof, heavy-duty,
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.
Do not operate the vehicle with the
heater cord permanently attached to
the vehicle. Possible heater cord and
thermostat damage could occur.
Driving and Operating

While in use, do not let the heater
cord touch vehicle parts or sharp
edges. Never close the hood on the
heater cord.
Before starting the vehicle, unplug the
cord, reattach the cover to the plug,
and securely fasten the cord. Keep the
cord away from any moving parts.
5. Before starting the engine, be sure to
unplug and store the cord as it was
before to keep it away from moving
engine parts. If you do not, it could be
damaged.
Contact your dealer for information on how
long to use the heater in your
particular area.
