2008 CADILLAC ESCALADE ESV air conditioning

To replace the battery:
1. Separate the halves of the transmitter with a at,
thin object inserted into the notch, located above
the metal base.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly. Remote Vehicle Start Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside of the
vehicle. It may also start up the vehicle’s heating or
air conditioning systems and rear window defogger.
Normal operation of the system will return after the key
is turned to the ON/RUN position.
During a remote start, the climate control system will
default to a heating or cooling mode depending on the
outside temperatures.
During a remote start, if your vehicle has an automatic
climate control system and heated seats, the heated
seats will turn on during colder outside temperatures and
will shut off when the key is turned to ON/RUN. If
your vehicle does not have an automatic climate control
system, during remote start, you will need to manually
turn the heated seats on and off. See Heated Seats
on page 1-4 for additional information.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using the remote start to have the vehicle in
view when doing so. Check local regulations for
any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.

Automatic Operation AUTO (Automatic): When automatic operation is
active the system will control the inside temperature, the
air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current temperature(s) and AUTO
come on the display. The current delivery mode and
fan speed will also be displayed for approximately
ve seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will run
when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it is hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down your vehicle. The light on the
button will come on in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F (23°C)
temperature setting and allow about 20 minutes
for the system to regulate. Use the driver’s or
passenger’s temperature buttons to adjust the temperature setting as necessary. If you choose the
temperature setting of 60°F (15°C), the system
will remain at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C),
the system will remain at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Be careful not to cover the sensor located on the top of
the instrument panel near the windshield. This sensor
regulates air temperature based on sun load and
also turns on your headlamps.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the engine coolant
temperature. Pressing the fan switch will override this
delay and change the fan to a selected speed.
O (Off): Press the driver’s side temperature knob to
turn off the climate control system. Outside air will
still enter the vehicle, and will be directed to the oor.
This direction can be changed by pressing the mode
button. The temperature can also be adjusted using
either temperature knob. Press the up or down arrows
on the fan switch, the defrost button, the AUTO
button, driver’s side temperature knob, or the air
conditioning button to turn the system on when it is off.
3-27

@ (Recirculation): Press this button to turn the
recirculation mode on. When the button is pressed, an
indicator light will come on.
This mode keeps outside air from entering the vehicle. It
can be used to reduce outside air and odors from
entering your vehicle. Recirculation may also help cool
the air inside your vehicle more quickly once the
temperature inside the vehicle is less than the outside
temperature. The recirculation mode cannot be used
with oor, defrost, or defogging modes.
If you try to select recirculation in one of those modes,
the indicator will ash three times and turn off. The
air conditioning compressor will also come on when this
mode is activated. While in recirculation mode the
windows may fog when the weather is cold and damp.
To clear the fog, select either the blend or defrost
mode and increase the fan speed. Recirculation mode
can be turned off by pressing the button again, or turning
off the engine. Air Conditioning
# (Air Conditioning): Press this button to turn the
air conditioning (A/C) compressor on and off. When
air conditioning is selected, an indicator light will come
on to let you know that the air conditioning has been
activated.
Pressing this button when the outside temperature is
too cool for air conditioning will make the air conditioning
indicator ash three times and then turn off indicating
the air conditioning mode is not available. If the air
conditioning is on and the outside temperature drops
below a temperature which is too cool for air
conditioning to be effective, the air conditioning light will
turn off to let you know the air conditioning mode has
been canceled.
On hot days, open the windows long enough to let hot
inside air escape. This helps to reduce the time it
takes for your vehicle to cool down. It also helps the
system to operate more efficiently.
The air conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
If your vehicle has heated seats or heated and cooled
seats, see Heated Seats on page 1-4 or Heated
and Cooled Seats on page 1-5 .

Defogging and Defrosting Fog on the inside of the 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 or frost 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.
Use the mode up and down arrows to select the defog
or defrost modes.
- (Defog): This mode directs air to the windshield,
oor outlets, and side window vents. When you select this
mode, the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is close to freezing. The recirculation mode cannot be
selected while in the defog mode. Do not drive the vehicle
until all the windows are clear.
0 (Defrost): This mode directs a portion of the air to
the windshield and side window vents and some to
the oor vents. In this mode, the system will
automatically force outside air into your vehicle. The
recirculation mode cannot be selected while in the
defrost mode. The air conditioning compressor will run
automatically in this setting, unless the outside
temperature is close to freezing. 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 from the rear window.
< (Rear Window Defogger): The rear window
defogger will turn off automatically after it has been
activated. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Do not drive the vehicle until all the windows are clear.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
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 air outlets located in the center and on the side
of your instrument panel to direct the airow.
Operation Tips
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
When you enter a vehicle in cold weather, press the
fan up button to the maximum fan level before
driving. This helps clear the intake ducts of snow
and moisture, and reduces the chance of fogging
the inside of your window.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
Adding outside equipment to the front of your
vehicle, such as hood-air deectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle. Rear Air Conditioning and Heating
System and Electronic Climate
Controls For vehicles with the rear heat and air conditioning
controls, they are integrated with the rear seat audio
controls located in the center console. The system can
be controlled from the front controls as well as the
rear controls.
To turn the system on, press the AUX button on the
front climate control system, an indicator will be
lit. Pressing the AUX button the rst time will turn the
rear system on in a mimic mode. In this mode, the
airow in the rear will be approximately the same
direction, temperature, and fan speed as the front.
Pressing the AUX button again turns the rear system
and the indicator off.
If the rear controls are adjusted, the system enters a
rear independent mode. Airow in the rear will then be
directed according to the settings of rear controls.
The rear system can be turned off by pressing the AUX
button on the front climate control system and the
indicator will turn off.
If the indicator in the front AUX button is off, the rear
system is off.

CHECK TIRE PRESSURE This message displays when the pressure in one or
more of the vehicle’s tires needs to be checked.
This message also displays LEFT FRONT, RIGHT
FRONT, LEFT REAR, or RIGHT REAR to indicate which
tire needs to be checked. You can receive more than
one tire pressure message at a time. To read the other
messages that may have been sent at the same
time, press the set/reset button. If a tire pressure
message appears on the DIC, stop as soon as you can.
Have the tire pressures checked and set to those
shown on the Tire Loading Information label. See Tires
on page 5-56 , Loading Your Vehicle on page 4-35 ,
and Inflation - Tire Pressure on page 5-62 . The DIC also
shows the tire pressure values. See DIC Operation
and Displays on page 3-49 . If the tire pressure is low,
the low tire pressure warning light comes on. See
Tire Pressure Light on page 3-42 . DRIVER DOOR OPEN This message displays and a chime sounds if the driver
door is not fully closed and the vehicle is in a drive
gear. Stop and turn off the vehicle, check the door for
obstructions, and close the door again. Check to
see if the message still appears on the DIC.
ENGINE HOT A/C (Air Conditioning)
TURNED OFF This message displays when the engine coolant
becomes hotter than the normal operating temperature.
See Engine Coolant Temperature Gage on page 3-42 .
To avoid added strain on a hot engine, the air
conditioning compressor automatically turns off. When
the coolant temperature returns to normal, the air
conditioning compressor turns back on. You can
continue to drive your vehicle.
If this message continues to appear, have the system
repaired by your dealer/retailer as soon as possible
to avoid damage to the engine.

4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mixture to the coolant surge tank
until the level reaches the FULL COLD mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
6. Verify coolant level after engine is shut off and the
coolant is cold. If necessary, repeat coolant ll
procedure Steps 1 through 6. Engine Fan Noise Your vehicle has electric cooling fans. You might hear
the fans spinning at low speed during most everyday
driving. The fans can turn off if no cooling is required.
Under heavy vehicle loading, trailer towing, and/or
high outside temperatures, or if you are operating the
air conditioning system, the fans can change to
high speed and you might hear an increase in fan noise.
This is normal and indicates that the cooling system
is functioning properly. The fans change to low speed
when additional cooling is no longer required.
