Heating
On cold days use FLOOR and the outside air button
pushed in with the temperature knob all the way in the
red area. The system will bring in outside air, heat it and
send it to the floor ducts.
If your vehicle has an engine coolant heater, 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 to
provide heat. See “Engine Coolant Heater” in the Index.
Ventilation
For mild outside temperatures when little heating or cooling
is needed, use UPPER and outside air to direct air through
your vehicle. Your vehicle also has the flow
- through
ventilation system described later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use DEFOG.
Air Conditioning with Automatic and
Auxiliary Temperature Control
(If Equipped)
With this system, you set a temperature. You can then
either let the system adjust airflow and force to maintain
the temperature, or you can manually adjust the flow
and force. The system works best if you keep your
windows closed while using it.
