Ventilation System - Chevrolet 1998 Prizm Owner's Manual

Bi-Level
You may want to use bi-level heating on cool, but sunny
days. This setting directs outside air toward your body
and warmer air toward your feet.
Move the air intake lever to CIRCULATE and turn the
airflow knob to BI-LEVEL. Turn the temperature knob
to the white area and the fan knob toward HI.
Ventilation System
For mild outside temperatures, when very little heating
is required, you can still direct outside air through
your vehicle.
Move the air intake lever to CIRCULATE and turn the
airflow knob
to
VENT. Turn
the
temperature knob to a
comfortable setting and the fan knob toward HI.
Airflow through the side vents is normal in all airflow
modes. To optimize the effectiveness of your system in
FLOOR, DEFOG, or DEFROST modes, turn the
outboard vent (shut-off) thumbwheels down to the
closed position.
Your vehicle's flow-through ventilation system
supplies outside air into the vehicle when it
is
moving.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running and the air intake
lever is at CIRCULATE.
Adjust the direction of airflow by moving the
louvered vents.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.
