The engine heater, if available, 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 engine 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 Heater
The electrical cord is on the passenger side of the engine compartment, in front of the air cleaner.
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.
Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.

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.
