Engine Coolant Heater

The vehicle may have this feature. In very cold weather,
0°F ( 18°C) or colder, the engine coolant heater can
help. The vehicle will start easier and get better
fuel economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum of four
hours prior to starting your vehicle. At temperatures
above 32°F (0°C), use of the coolant heater is not
required.

To Use the Engine Coolant Heater

1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is attached to the underside of the vehicle's
diagonal brace, which is located above the engine
air cleaner/filter assembly.
3. Plug it into a normal, grounded 110-volt AC outlet.
CAUTION:
{
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a fire. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Unplug and store the cord as it was before to keep
it away from moving engine parts, before starting
the engine. If this is not done, the cord could
be damaged.
