Automatic Operation
Press the AUTO button on the Automatic Temperature
Control (ATC) Panel.
Next, adjust the temperature you would like the system
to maintain by adjusting the driver and front passenger
temperature control buttons. Once the desired tempera-
ture is displayed, the system will achieve and automati-
cally maintain that comfort level.
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.
UNDERSTANDING YOUR INSTRUMENT PANEL 423
The temperature can be displayed in U.S. or Metric units
by selecting the US/M customer-programmable feature.

To provide you with maximum comfort in the Automatic
mode, during cold start-ups, the blower fan will remain
on low until the engine warms up. The blower will
increase in speed and transition into Auto mode.
Manual Operation
This system offers a full complement of manual override
features.
NOTE: Each of these features operate independently
from each other. If any one feature is controlled manually,
temperature control will continue to operate automati-
cally.
