2009 CADILLAC STS center console

Sensors
The solar sensor located on the instrument panel, near
the windshield, monitors the solar heat.
The interior temperature sensor located on the
instrument panel to the right of the steering wheel,
measures the temperature of the air inside the vehicle.
The climate control system uses the information
from these sensors to adjust the temperature, the fan
speed and the air delivery, in order to maintain the
selected temperature. The system may also supply
cooler air to the side of the vehicle facing the sun.
Do not cover the sensors or the automatic climate
control system will not work properly.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airow.
Turn the thumbwheel towards the vehicle door to open
the outlets and allow the maximum amount of air to
enter your vehicle. Turn the thumbwheel towards
the center console 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 3-54.

Rear Climate Control System
The vehicle has a rear climate control system. The base
model includes air outlets in the rear of the center console
for cooling and under-seat air outlets for heating. The
temperature, amount of airow, and the air delivery mode
is controlled automatically by the front climate control
system.
Some vehicles may have an optional climate control
panel for the rear passenger, located on the back of the
center console.

The front climate control system automatically controls
the amount of airow to the rear seat passengers,
regardless of optional equipment. Airow to the rear
system turns off when defrost is selected on the front
climate control panel, in order to direct air to clear the
windshield.
z(Heated Seat):Press to turn on rear heated seats.
There are two buttons, each with three indicator lights,
located between the climate control knobs on the rear
climate control panel.
Keep the area under the front seats clear of any objects
so the air in the vehicle can circulate effectively.

again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on

LANE DEPARTURE SYSTEM
UNAVAILABLE
If your vehicle has the Lane Departure Warning (LDW)
system, this message may display if the LDW system
does not activate due to a temporary condition. See the
Index in the Navigation manual for more information.
LEFT REAR DOOR AJAR
This symbol appears with
this message.
This message displays when the driver side rear door
is not closed completely. Make sure that the door
is closed completely.
NO FOBS DETECTED
This message displays if the vehicle does not detect the
presence of a keyless access transmitter when you have
attempted to start the vehicle or a vehicle door has just
closed. The following conditions may cause this message
to appear:
Driver-added equipment plugged into the accessory
power outlet on the center console is causing
interference. Examples of these devices are cell
phones and cell phone chargers, two-way radios,
power inverters, or similar items. Try moving the
keyless access transmitter away from these devices
when starting the vehicle. In addition, PDA devices
and remote garage and gate openers may also
generate Electromagnetic Interference (EMI) that
may interfere with the keyless access transmitter.
Do not carry the keyless access transmitter in the
same pocket or bag as these devices.
The vehicle is experiencing Electromagnetic
Interference (EMI). Some locations, such as airports,
automatic toll booths, and some gas stations, have
EMI elds which may interfere with the keyless
access transmitter.
3-86

If moving the transmitter to
different locations within
the vehicle does not help,
place the transmitter in the
center console transmitter
pocket with the buttons
facing forward and then
press the START button.
The vehicle’s battery voltage is low. The battery
voltage must be above 10 volts for the keyless
access transmitter to be detected properly.
NO FOB OFF OR RUN?
This message displays when the keyless access
transmitter is not detected inside the vehicle while you
are trying to turn the ignition off. Your vehicle may be
near a strong radio antenna signal causing the keyless
access system to be jammed. The vehicle remains in
ACCESSORY until OFF or START has been pressed or
10 minutes has expired. If you turn the ignition off and
you cannot nd the keyless access transmitter, you will
not be able to restart the vehicle. The keyless access
transmitter needs to be inside of the vehicle in order for
the vehicle to start. SeeStarting the Engine on page 2-27
for more information.
