Automatic Operation
1. Press the AUTO button on the Front Upper ATC Panel
and the word AUTO will illuminate in the front ATC
display, along with three temperatures for driver, front
passenger, and rear seats. The system will then automati-
cally regulate the amount of airflow.
2. Next, adjust the temperature you would like the
system to maintain, by adjusting the driver, front passen-
ger, and rear seat rotary temperature knobs. Once the
desired temperature is displayed, the system will achieve
and automatically maintain that comfort level.
3. When the system is set up for your comfort level, it is
not necessary to change the settings. You will experience
the greatest efficiency by simply allowing the system to
function automatically.
NOTE:
•
It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible.
•
The temperature can be displayed in English or Metric
units by selecting the “Display Units of Measure in”
customer-programmable feature. Refer to the “Elec-
tronic Vehicle Information Center (EVIC) — Customer-
Programmable Features” in this Section.
To provide you with maximum comfort in the automatic
mode, during cold start-ups, the blower fan will remain
on low and the DELAY symbol will appear in the front
ATC display, until the engine warms up. The fan will
engage immediately if the DEFROST mode is selected, or
by pressing the Front Upper ATC Panel blower rocker
button and setting the fan to any fixed blower speed.
