Oldsmobile 2002 Alero - Manual (Page 141)

3-4
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use bi
- level with the temperature knob in the
middle and the A/C button pressed in. The system
directs slightly warmer air to your lower body.
Heating
On cold days, use floor mode 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 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. When you switch to defog or defrost modes
your system will automatically move from recirculation
into outside air. When you move the mode knob back to
vent or bi–level, the system will move back into
recirculation. When the car is turned off and back on the
system will default to outside air automatically.
The recirculation setting in cold weather should be used
only for outside odor control so that fog formation on
the windows is reduced.
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 mode 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.
