Manual override buttons Your EATC has six buttons which allow you to make special selections. The buttons are located along the bottom edge of the EATC and allow you to determine where the air will be discharged. Pressing any override button changes the air discharge location only. It does not affect the ability of the system to control temperature or the fan speed. Return to fully automatic operation by pushing the AUTO button. MAX A/C button The MAX A/C feature allows for faster cooling because air is drawn from inside the vehicle. Using inside air causes the fan to sound louder which is normal for this selection. The display window will change to indicate MAX A/C and the airflow will be from the instrument panel registers. To exit, push AUTO or any of the other five manual override buttons. VENT button Press this button to select outside air through the instrument panel registers. The display window will show the set temperature and VENT to the lower right of the temperature. Your EATC will heat the air if the temperature you have selected is warmer than the outside air coming into the vehicle. However, the air will NOT be cooled regardless of the temperature setting. Airflow will be from the instrument panel registers. 101
