Do not attach anything like a temporary vehicle license
or a decal across the defogger grid on the rear window.
NOTICE:
Don’t use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.
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.
