2009 CADILLAC SRX climate control

Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of
charge. It then adjusts the voltage for best performance
and extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage move
up or down. This is normal. If there is a problem, an
alert will be displayed.The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on: headlamps, high beams, fog lamps,
rear window defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer loads, and
loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 3-51.

Automatic Operation
The system automatically controls the fan speed, air
delivery, and air conditioning in order to heat or cool the
vehicle to the desired temperature.
To place the system in automatic mode do the following:
AUTO (Automatic Mode):
1. Turn the fan and mode controls to the AUTO
position. This also sets the recirculation mode
to automatic operation on the display.
2. Press the up or down arrows to adjust the
temperature to a comfortable setting between
70°F (21°C) and 80°F (27°C).
3. Allow the system time to stabilize. This might take
several minutes in very hot or cold weather. Then
adjust the temperature, as needed for best comfort.
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. In cold weather, the system starts at reduced
fan speeds to avoid blowing cold air into the vehicle
until warmer air is available. The automatic system
starts out blowing air at the oor, but changes modes
automatically as the vehicle warms up to maintain the
chosen temperature setting. The length of time
needed to warm the interior depends on the outside
temperature and the amount of time that has passed
since the vehicle was last driven.
3-22

«ª(Driver’s Temperature Controls):Press the up
or down buttons closest to the driver to increase or
decrease the temperature inside the vehicle.
«ª(Passenger’s Temperature Controls):Press the
up or down buttons closest to the passenger to
increase or decrease the temperature for the front
passenger. If the passenger climate control system is
off, pressing either of these buttons turns it on.
Manual Operation
O(On/Off):Press to turn the climate control system on
or off. While off, adjusting any button or control,
except recirculation and rear window defog turns the
system back on. The air inlets default to outside
air when the climate control system is turned off.
9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. The fan
speed remains at this speed until it is turned to AUTO
or adjusted to a different level. In the automatic position,
the blower might go to a lower speed during an
OnStar
®session to limit the background noise.Air Delivery Mode Control:
To change the current mode, select one of the following:
AUTO:Turns on the automatic delivery mode
operation.
F(Vent):Air is directed to the instrument panel outlets.
*(Bi-Level):Air is directed to the instrument panel
outlets and the oor outlets. The temperature of the air
to the oor will be warmer than the air to the upper
outlets.
7(Floor):Air is directed to the oor outlets with some
air directed to the outboard outlets, side window
outlets, and defroster outlet.
W(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield and oor
outlets, with some air going to the outboard outlets and
side window outlets. When selected, the system
turns off recirculation and runs the air conditioning,
unless the outside temperature is at or below freezing.
If recirculation mode is selected while using the
defog mode, the system recirculates air for about
10 minutes and then returns to outside air mode.
3-23

0(Defrost):This mode clears the windshield of fog or
frost more quickly. Air is directed to the windshield
with some air going to the side window outlets. When
selected, the system turns off recirculation and runs the
air conditioning compressor, unless the outside
temperature is at or below freezing.
Do not drive the vehicle until all the windows are clear.
PASS (Passenger’s Climate Control):Press to
turn the passenger climate control system on or off.
Then press the passenger
«orªbuttons to adjust
the temperature. Pressing PASS again automatically
sets the passengers temperature to the drivers setting.
Turning off the passenger temperature display does
not turn off the passenger climate control system.
Air Inlet Modes
There are three options for bringing air into the climate
control system. They are controlled by pressing the
outside air button on the climate control panel.The climate control display indicates one of the
following three modes:
9(Auto Air Inlet):This mode lets the automatic
climate control system choose the best air inlet position
for cooling or warming the vehicle. To have full
automatic climate control, the fan and mode controls
must be set to the AUTO position. On hot days,
the recirculation mode may be selected automatically.
?(Recirculation):This 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.
The recirculation mode cannot be used with oor, defog,
or defrosting modes. Using recirculation for long periods
of time can 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 auto air inlet or
outside air.
F(Outside Air):Air is pulled from outside the
vehicle. Outside air is always selected in defrost mode
to prevent fogging.
3-24

Air Conditioning
#
(Air Conditioning):Press to turn the air
conditioning on or off, and override the automatic
system. When selecting the AUTO fan or AUTO mode,
the air conditioning comes on automatically, as
necessary.
The air conditioning system removes moisture from the
air, so water might drip underneath the vehicle while
idling or after turning off the engine. This is normal.
Sensors
There is a solar sensor
located on top of the
instrument panel, near the
windshield.There is an interior
temperature sensor
located below the climate
control system next to
the steering wheel.
An ambient sensor is located behind the grille in front
of the vehicle.
These sensors help the climate control system
automatically control the temperature setting.
The system can supply cooler air to the side of the
vehicle facing the sun. The recirculation mode will also
be used as needed to maintain cool outlet temperatures.
Do not cover any of the sensors or the climate control
system might not work properly.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press to turn the rear window
defogger on or off. The rear window defogger stays on
for about 20 minutes, before turning off. At higher
vehicle speeds, the rear defogger can stay on
continuously. Each additional press runs the defogger
for about 10 minutes.
When the rear window defogger is pressed, the heated
outside mirrors come on. They help to clear fog or
frost from the surface of the mirror. SeeOutside Heated
Mirrors on page 2-40.
Notice:Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not 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.
Operation Tips

Clear away any ice, snow, or leaves from the air
inlets at the base of the windshield that could
block the ow of air into the 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 the vehicle more
effectively.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter might need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-28.
Set the climate control system to AUTO fan and
mode and then adjust the temperature setting
up or down a few degrees for best comfort.
