wheel CADILLAC CTS 2005 1.G Owner's Manual

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, then use the information to maintain
the selected temperature by initiating needed
adjustments 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.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 you
select this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing. The
recirculation mode is cancelled when you enter defog
mode. If you select recirculation while in defog mode, it
will be cancelled after 10 minutes.
If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-31
for more information.
3-30

0(Defrost):Pressing defrost direts 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. Recirculation cannot be selected while
in the defrost mode.
This mode may also cause the fan speed and air
temperature to increase.
If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-31
for 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.The rear window defogger will turn off about 10 minutes
after the button is pressed. Or, 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.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.
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.
3-31

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.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-32.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/lter, it needs to be changed
periodically. For how often to change the passenger
compartment air lter, seeScheduled Maintenance on
page 6-4.
Using your climate control system without the passenger
air lter installed may allow water or other debris to
enter the system. This could cause a water leak
or noises. Make sure to install a new air lter after
removing the old one.
The passenger compartment air lter is located
underneath the hood below the windshield wiper arm on
the passenger’s side of the vehicle. SeeEngine
Compartment Overview on page 5-12for more
information on location.
3-32

Use the procedure listed below to replace the passenger
compartment air lter:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them off
again when the wipers are straight up and down
on the windshield.
This will allow you access to the leaf screen
under which is located the passenger compartment
air lter.
3. Open the hood to access the engine compartment.
SeeHood Release on page 5-11for more
information.
4. Remove the four screws that hold the leaf screen in
place and lift off the screen by lifting and sliding
toward the center of the vehicle.
5. Pull out on the two tabs located on each end of the
lter cover.
6. Lift the lter cover off by pulling it straight upward.
7. Remove the old lter and insert a new one.
Make sure the arrow on the lter is pointing toward
the passenger compartment.
SeeNormal Maintenance Replacement Parts on
page 6-14for the correct part number for the lter.
8. Reverse Steps 1 through 6 to reinstall the cover.Steering Wheel Climate
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 3-7for more information on programming
these controls.

Traction Control System (TCS)
Warning Light
If the TC (traction control)
warning light comes on
and stays on, there may be
a problem with the
traction control system.
The TC (traction control) warning light will come on
briey when you turn the ignition to ON. If it doesn’t
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 (traction control) on/off
button located in the glove box for the CTS and on
the steering wheel for the CTS-V.
If the TC (traction control) 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 inspected as soon as possible. SeeTraction
Control System (TCS) (CTS) on page 4-8orTraction
Control System (TCS) (CTS-V) on page 4-9for more
information.
Engine Coolant Temperature
Warning Light (CTS)
This light tells you that
your engine is very hot.
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, the bulb may be burned out. See your dealer
for assistance in changing the bulb.
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 sound when this light is on, also.

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. SeeTraction Control System (TCS)
