Automatic Operation
AUTO (Automatic):The system automatically controls
fan speed, air delivery, and air conditioning in order
to heat or cool the vehicle to the desired temperature.
When the indicator light is on, the system is in full
automatic operation. If the air delivery mode or fan
setting is manually adjusted, the auto indicator turns
off and displays will show the selected settings.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature setting
will not cause the system to heat or cool any faster.
If the system is set at the warmest temperature
setting, it remains in manual mode at that
temperature and it will not go into automatic mode.
To avoid blowing cold air in cold weather, the system
delays turning on the fan until warm air is available.
The system starts out blowing air at the oor, but can
automatically change modes as the vehicle warms
up to maintain the chosen temperature setting.
The length of time needed for warm up depends on
the outside temperature and the length of time that
has elapsed since the vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.

M/F(Recirculation/Outside Air):Press this
button to switch between recirculation and outside
air modes. The indicator light comes on to show which
mode is being used. The recirculation mode recirculates
and helps to quickly cool the air inside the vehicle.
It can be used to prevent outside air and odors from
entering the vehicle. Press the auto button to have
the system select the best air delivery mode for
the temperature setting.
Recirculation is not available in the defrost mode and
automatically turns off 10 minutes after defog is selected.
This helps to limit window fogging in the vehicle.
Using recirculation for long periods of time could cause
the air inside the vehicle to become too dry or stuffy.
To prevent this from happening, after the air in the vehicle
has cooled, select outside air or press the auto button.
The outside air mode pulls fresh air from outside the
vehicle. Outside air is always selected in defrost mode to
prevent fogging.Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. It only works
when the ignition is in ON/RUN.
=(Rear Window Defogger):Press to turn the rear
window defogger on or off.
The rear window defogger stays on for about 15 minutes,
before turning off if the vehicle is moving at a slower
speed. At higher speeds, the rear window defogger may
stay on continuously. With each additional press, the
defogger runs for about 10 minutes. The defogger can
also be turned off by turning off the engine.
The heated outside rearview mirrors turn on when the
rear window defogger button is on and helps to clear
fog or frost from the surface of the mirror. SeeOutside
Heated Mirrors on page 2-53.
Notice:Do not try to clear frost or other material
from the inside of the front windshield and rear
window with a razor blade or anything else that is
sharp. This may damage the rear window defogger
grid and affect your radio’s ability to pick up
stations clearly. The repairs wouldn’t be covered
by your warranty.

Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.

Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:If the engine is operated with the tachometer
in the shaded warning area, the vehicle could be
damaged, and the damages would not be covered by
the vehicle warranty. Do not operate the engine with
the tachometer in the shaded warning area.The CTS-V tachometer has tracer lights that follow the
movement of the tachometer indicator. The tracer lights
can be turned off in the DIC Vehicle Customization.
SeeDIC Vehicle Customization on page 3-72for more
information.
For the CTS-V, the tracer lights also ash when it is
time to up-shift to avoid the engine speed limit.
SeeAutomatic Transmission Operation on page 2-36
orManual Transmission Operation on page 2-40
for more information.
Engine Speed Limiter
This feature prevents the engine speed from reaching
an unsafe level. If the level is too high, the throttle closes
or limits the fuel supply until the engine speed returns
to a safe level. Throttle operation and fuel supply returns
to normal when engine speed is lowered.
For the CTS-V, the tachometer tracer lights ashes prior
to reaching engine speed limit. The tracer lights also
ash on automatic transmission vehicles while in
the DSC or Tap Shift modes. United States and

check. Then, after several more seconds, the status
indicator will light either ON or OFF, or either the on
or off symbol, to let you know the status of the right
front passenger frontal airbag.If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag is enabled (may inate).
If the word OFF or the off symbol is lit on the passenger
airbag status indicator, it means that the passenger
sensing system has turned off the right front passenger
frontal airbag.
If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be
a problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
