Ram Trucks 2010 3500 - Owner Manual - Manual (Page 289)

Automatic Operation
1. Position the MODE control knob to the Auto position
on the Automatic Temperature Control (ATC) Panel.
2. Position the BLOWER control knob in the Auto posi-
tion on the ATC Panel.
3. Next, adjust the temperature you would like the
system to maintain by adjusting the driver and front
passenger temperature buttons. Once the desired tem-
perature is displayed, the system will achieve and auto-
matically maintain that comfort level.
4. 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
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.
