Engine 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.
To Use the Engine Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
attached to the diagonal brace
on the driver side of the engine
compartment.
3. 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.
4. Before starting the engine, be
sure to unplug and store the
cord as it was before to keep it
away from moving engine parts,
and prevent damage.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.
