Automatic Operation - Chevrolet 2008 Avalanche Owner's Manual

Passenger's Side Temperature Control
The passenger's temperature buttons can be used to
change the temperature of the air coming through the
system on the passenger's side of the vehicle. The
temperature can be adjusted even if the system is turned
off. This is possible since outside air will always flow
through the system as the vehicle is moving forward
unless it is set to recirculation mode. See "Recirculation"
later in this section.
Press the + or − buttons to increase or decrease the
cabin temperature. The passenger side display will show
the temperature setting decreasing or increasing.
The passenger's temperature setting can be set to
match the driver's temperature setting by pressing the
PASS button and turning off the PASS indicator. When
the passenger's temperature setting is set different than
the driver's setting, the indicator on the PASS button will
illuminate and both the driver's side and passenger's side
temperature displays will be shown.

Automatic Operation

AUTO (Automatic): When automatic operation is
active the system will control the inside temperature,
the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change
to show the current temperature(s) and AUTO will
be lit on the display. The current delivery mode
and fan speed will also be displayed for
approximately 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor
will run when the outside temperature is over
about 40°F (4°C). The air inlet will normally be
set to outside air. If it is hot outside, the air inlet
may automatically switch to recirculate inside air
to help quickly cool down your vehicle. The light
on the button will illuminate in recirculation.
