front ATC unit is in the “AUTO” position. Once the
desired temperature is displayed, the system will achieve
and maintain that comfort level automatically. 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 U.S. or Metric by
selecting the US/M customer programmable feature.
Refer to the “Overhead Console-Customer Program-
mable Features” in Section 3 of this manual. To provide you with maximum comfort in the automatic
mode, during cold start-ups the blower fan will remain
off and “DELAY” will appear in the front ATC display
until the engine warms up. Also, an estimate of the time
remaining until the “DELAY” is over will appear peri-
odically in the display. However, the fan will engage
immediately if the defrost mode is selected or by rotating
the blower control to any fixed blower speed.
This feature may be disabled using the following proce-
dure:
•Press and hold the Heated Rear Window and Auto LO
buttons for 5 seconds.
•The “DELAY” symbol will flash to indicate that the
feature as been disabled.

Manual Operation
This system offers a full complement of manual override
features. The “AUTO” symbol in the front ATC display
will be turned off when the system is being used in the
manual mode. NOTE:
Each of these features operate independently
from each other. If any one feature is controlled manually,
the remaining features will continue to operate automati-
cally.
The left blower control knob can be set to any fixed
blower speed by rotating the knob from low to high. The
fan will now operate at a fixed speed until additional
speeds are selected or either the Auto HIor Auto LO
buttons are pressed. This allows the front occupants to
control the volume of air circulated in the vehicle and
cancel the “AUTO” mode.
The operator can also select the direction of the air by
rotating the right mode control knob to one of the
following positions.
