Heating
On cold days, use FLOOR and the outside air button
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 outlets.
Your vehicle has heat ducts that are directed toward the
rear seat. Keep the area under the front seats clear of
obstructions so that the heated air can reach the rear
seat passengers.
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.
Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows. For each setting, adjust the temperature
knob as desired.
To defrost the front window quickly, turn the temperature
knob all the way in the red area. Use FRONT DEFROSTER
and adjust the fan to the highest speed. To warm passengers
while keeping the front window clean, use DEFOG.
Your vehicle is equipped with side window defogger
vents. The side window defogger vents are located
above the side instrument panel vents. To defrost the
side windows, turn the temperature knob all the way
in the red area. Use FLOOR and adjust the fan to
the highest speed.
To control fogging of the windows, turn the temperature
knob all the way in the red area. Use DEFOG and adjust
the fan to the highest speed.
To defog the side windows while using air conditioning,
use BI
- LEVEL and adjust the fan to the highest speed
and press the A/C button so that the indicator light is
glowing. For added airflow to the side windows aim
the side vents toward the windows and close the
center vents.
