There is also a temperature sensor located beside
the audio system on the driver's side of the vehicle.
This sensor reads the inside air temperature and
helps to establish ventilation system requirements
while operating in AUTO mode. Do not cover
the temperature sensor or the system will not
work properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or moisture condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or
frost from the windshield more quickly.
É
(Defog): Press the MODE button until the defog
symbol appears on the automatic climate control
system display.
This mode directs most of the air to the windshield and
the floor outlets. A small amount of air is also directed
to the outboard outlets for the side windows.
To help clear the side windows quickly, do the following:
1. Select the bi-level mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the temperature.
