Driving and Operating

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).
