3-7 Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT (on the standard system)
to direct outside air through your vehicle. Air will flow
through the middle instrument panel outlets.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it's moving. When the
vehicle is not moving, you can get outside air to flow
through by selecting any air choice (except the rear
window defogger) and any fan speed.
H±23±0020±T
Your vehicle has air outlets that allow you to adjust the
direction and amount of airflow inside the vehicle. Push
the outlet up or down to direct airflow to your
preference. Increase or reduce the amount of airflow by
opening and closing the louvers. Opening and closing
the louvers will also direct airflow from side
-to-side.
H±23±0025±T
If you have the rear seat passenger outlet, it's attached to
the back of the console. You can adjust the airflow
toward either seating area, the floor or upward. Turn the
end knobs up and down to direct airflow. Increase or
reduce the amount of airflow by adjusting the lever
between the two rear vents up or down. Open and close
the louvers to direct airflow from side
-to-side.

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 better, reducing the chance of
fogging your windows.

When you enter a vehicle with the standard system
in cold weather, select HEATER to supply air
through the floor outlets. Then turn the fan on high
for a few moments before driving away. This will
blow moist air from the intake outlets toward the
floor, not the windshield. It reduces the chance of
fogging your windows. If you have the electronic
system, the AUTO setting will do this for you.
Manual operation of the electronic system in the
HEAT mode will also supply air through the
floor outlets.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

When the engine idles for a long time, the exterior
temperature sensor may cause the system to blow air
that is too cool. Once the vehicle is moving again the
system will try to maintain the set temperature inside
your vehicle.
When you start your vehicle and the EXT TEMP
display flashes (electronic system only) for some
time, the system may need repair. See your dealer.
Defogging and Defrosting
On cool, humid days, use DEFOG to keep the
windshield and side windows clear. Use DEFROST to
remove fog or ice from the windshield quickly in
extremely humid or cold conditions.
If you have the standard system, use DEFOG and adjust
the fan speed to your comfort level. Use DEFROST
with the temperature toward the red area and the fan
control toward high.
If you have the electronic system, press the DEFOG
button and adjust the fan speed by pressing the fan
button up or down to your comfort level. If you select
DEFROST from AUTO, the system will control the fan
speed. Adjust the temperature to your comfort level by
pressing the TEMP up or down button

3-9 Rear Window Defogger
H±23±4004±RH±23±0007±T
The lines you see on the rear window warm the glass.
Press the button to start warming your window. If you
have the standard system, a light will glow in the switch
while the defogger is working.After 10 minutes it will turn off by itself, or press the
button during the heating cycle to turn it off. If you need
additional warming time, push the button again. The
system will then operate for five minutes before going
off by itself.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the defogger grid. The repairs wouldn't be
covered by your warranty.
