If your vehicle has an engine coolantheater, you can use it to help your system provide warm air faster when it's cold outside(0°F (-18°C) or lower). An engine coolant heater warms the coolant your engine and heating system use toprovide heat. See "Engine Coolant Heater" in the Index. Rear Window Defogger The rearwindow defogger uses a warming grid to remove fog from the rear window. Press the button to turn the defogger on. It will turn itself off after about ten minutes. Ventilation For mild outside temperatures when little heating or cooling is needed, use VENT to direct outside air through your vehicle. Your vehicle also has the flow-through ventilation system described later in this section. If you turn it on again, the defogger will only for about run five minutes before turning off. You can also turn it off by turning off the ignition or pressing the button again. Do not attach anything like a temporary vehicle license or decal across the defogger grid.
