Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm‐up in
cold weather conditions at or below −18°C (0°F).
Vehicles with an engine coolant heater should be
plugged in at least four hours before starting. Some
models have an internal thermostat in the cord which
will prevent engine coolant heater operation at
temperatures above −18°C (0°F).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the front of the engine
compartment, on the passenger side of the vehicle.
3. You must remove the plastic cap to access
the plug.
4. Plug it into a normal, grounded 110-volt AC outlet.
{
WARNING:
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.
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.
