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
units by selecting the US/M customer-programmable
feature. Refer to the “Electronic Vehicle Information
Center (EVIC) — Customer-Programmable Features
(SETUP)” in this section of the manual.
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 ATC
display until the engine warms up. The blower will
increase in speed and transition into Auto mode and
DELAY will no longer be illuminated in the display. The
blower will engage immediately if the Defrost mode is
selected, or by adjusting the blower control knob and
setting the fan to any fixed speed.
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,
the temperature doors will continue to operate automati-
cally.
There are six fixed blower speeds. Use
this control to regulate the amount of
air forced through the system in any
mode you select. The blower speed
increases as you move the control
clockwise from the OFF position.
The blower fan speed can be set to any fixed speed by
adjusting the blower control knob. The fan will now
operate at a fixed speed until additional speeds are
