Engine Heater

The engine coolant heater,
if equipped, can help in cold
weather conditions at or below 18 °
C (0 °F) for easier starting and better
fuel economy during engine
warm-up. Plug in the coolant heater
at least four hours before starting
the vehicle. An internal thermostat
in the plug end of the cord 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 electrical
cord is on the driver side of the
engine compartment, between
the fender and the engine
compartment fuse block.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly
3. Plug it into a normal, grounded
110-volt AC outlet.

Improper use of the heater cord
or an extension cord can damage
the cord and may result in

three-prong electrical utility
receptacle that is protected

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
