Engine Heater
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
coolant heater at least four hours
before starting the vehicle. An
internal thermostat in the plug end
of the cord will prevent engine
heater operation at temperatures
above
−
18 °C (0 °F).
To Use the Engine 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.
