Sensors
There is a solar sensor located on the instrument
panel, near the windshield.There is also an interior
temperature sensor
located to the right of
the steering wheel
on the instrument panel.
These sensors monitor the solar radiation and the
air inside your vehicle, they use the information to
maintain the selected temperature by adjusting to
the temperature, the fan speed, and the air delivery
system. The system may also supply cooler air to
the side of the vehicle facing the sun. The
recirculation mode will also be activated, as
necessary. Do not cover the sensors or the
automatic climate control system will not work
properly.
192

Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear fog from your windshield.
Use the defog mode to clear the windows of fog
or moisture and warm the passengers. Use
the defrost mode to remove fog or frost from the
windshield more quickly.
yNz(Mode):Press this button until defog
appears on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows.
When this mode is selected, the system turns off
recirculation and runs the air-conditioning
compressor unless the outside temperature is at
or below freezing. If recirculation mode is selected
while in defog mode, it will be cancelled after
10 minutes.
If there is fog on the side windows, turn the
thumbwheel on the outboard outlets to the side
window defog position. SeeOutlet Adjustment on
page 194for more information.
0(Defrost):Pressing defrost directs most of the
air to the windshield, with some air directed to
the side windows. In this mode, the system
will automatically turn off recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
If there is fogging on the side windows, turn the
thumbwheel on the outboard outlets to the
side window defog position. SeeOutlet Adjustment
on page 194for more information. Do not drive
the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON.
=(Rear Window Defogger):Press this button
to turn the rear window defogger on or off.
Be sure to clear as much snow from the rear
window as possible.
193

The rear window defogger will turn off about
10 minutes after the button is pressed, but if the
vehicle’s speed is above 30 mph (48 km/h),
the rear defogger will stay on continuously.
If turned on again, the defogger will only run for
about ve minutes before turning off. The defogger
can also be turned off by pressing the button
again or by turning off the engine.
The heated outside rearview mirrors will heat to
help clear fog or frost from the surface of the mirror
when the rear window defogger button is on.
SeeOutside Heated Mirrors on page 141.
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.Outlet Adjustment
Use the knobs located in the center of each outlet
to change the direction of the airow. Use the
thumbwheels to open or close the outlets.
j(Side Window Defog):Turn the thumbwheel
to this symbol to use the side window defog
setting. The air coming through the outlets will be
directed toward the side windows to clear fog.
k(Open):Turn the thumbwheel to this symbol to
open the outlets completely and allow the
maximum amount of air to enter your vehicle.
A small amount of air will still be directed to the
side windows.
l(Closed):Turn the thumbwheel to this symbol
to close the outlets and minimize the amount
of air entering the vehicle.

Controls (CTS)
Your vehicle may have four controls that can be
programmed for use with the climate control
system.
The controls are located
on the left side of the
steering wheel.
SeeRecongurable Steering Wheel Controls
(SWC) (CTS) on page 169for more information on
programming these controls.
196

The TC warning light will come on briey when
you turn the ignition to ON. If it does not come on
then, have it xed so it will be ready to warn
you if there is a problem.
The light will also come on if you turn the traction
control system off using the TC on/off button
located in the glove box for the CTS and on the
steering wheel for the CTS-V.
If the TC warning light stays on or comes on while
you are driving, pull off the road as soon as
possible and stop carefully. Try resetting the
system by turning the ignition off then back on.
If the light still stays on or comes back on
again while you are driving, your vehicle needs
service. Have the Traction Control System (TCS)
inspected as soon as possible. SeeTraction
Control System (TCS) (CTS) on page 293
orTraction Control System (TCS) (CTS-V) on
page 295for more information.Engine Coolant Temperature
Warning Light (CTS)
This light will come on
when you rst start the
vehicle as a check
to let you know that the
light is working.
It will go out after a few seconds. If the light does
not come on, see your dealer.
If the light does not go out or if the light comes on
and stays on while you are driving, your vehicle
may have a problem with the cooling system. You
should stop the vehicle and turn off the engine
as soon as possible to avoid damage to the
engine. A warning chime will also sound when this
light is on.
SeeEngine Overheating on page 360for more
information.

Here are a few concerns some owners have had
about the fuel gage. All of these situations are
normal and do not indicate that anything is wrong
with the fuel gage:
At the gas station the gas pump shuts off
before the gage reads full.
The gage may change when you turn, stop
quickly or accelerate quickly.
It takes a little more or less fuel to ll the tank
than the gage indicated. For example, the gage
may have indicated that the tank was half full,
but it actually took a little more or less than half
the tank’s capacity to ll the tank.
Message Center
Message Center (CTS-V)
Your vehicle may have a message center that can
display information relating to powertrain uids, tire
pressures, vehicle dynamics, speedometer and
odometer information, and transmission status.
It also displays warning messages. There are
two different areas where message center
information will be displayed. One display is inside
of the tachometer and the other is inside of the
speedometer.These are the controls
for the message center.
They are located on
the left spoke of
the steering wheel.
The outboard switch (A and B) controls the display
of information inside of the tachometer. The
upper button (C) on the inboard switch controls
the display of information inside of the
speedometer. The lower button (D) on the inboard
switch turns the traction control on or off. See
