Engine Heater
The engine coolant 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 coolant heater operation at
temperatures above −18°C (0°F).
To Use the Engine Coolant
Heater

2. Open the hood and unwrap the
electrical cord.
