2007 CADILLAC ESCALADE ESV air condition

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.
Manual Operation
You may manually adjust the air delivery mode or
fan speed.
y9 z(Fan):The switch with the fan symbol
allows you to manually adjust the fan speed.
Press the up arrow to increase fan speed and the
down arrow to decrease fan speed.
Pressing this button when the system is off will
turn the system on.
Pressing either arrow while using automatic
operation will place the fan in manual operation.
The fan setting will display and the AUTO light will
turn off. The air delivery will remain in automatic
operation.
N(Mode):Press this button to manually change
the direction of the airow in your vehicle.
Repeatedly press the button until the desired
mode appears on the display.
When the system is turned off, the display will go
blank after displaying the current status of the
system.
222

H(Vent):This setting will deliver air to the
instrument panel outlets.
)(Bi-Level):This mode allows for split air to
the instrument panel outlets and to the oor
outlets. The ow can be divided between vent and
oor outlets depending upon where the knob is
placed between the settings. A little air is directed
towards the windshield and side window vents.
Cooler air is directed to the upper vents and
warmer air to the oor vents.
6(Floor):This mode directs most of the air to
the oor outlets, with some of the air directed
to the windshield, side window outlets, and
second row oor outlets. In this mode, the system
will automatically select Outside Air.
-(Defog):See “Defogging and Defrosting” later
in this section.
@(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.
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.
224

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
The rear heat and air conditioning controls are
part of 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
will turn the rear system and the indicator off.
If the rear controls are adjusted, the system will
enter 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.

Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the
engine is not running,
as a check to show you
it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with the
generator, the generator drive belt, or another
electrical problem. Have it checked right away.
Driving while this light is on could drain your
battery.
When this light comes on, the DIC will also display
the SERVICE BATTERY NOT CHARGING
SYSTEM message. SeeDIC Warnings and
Messages on page 250for more information.If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner, to reduce
the drain on your battery.
Brake System Warning Light
With the ignition on, the brake system warning
light will come on when you set the parking brake.
If you try to drive with the parking brake engaged,
a chime will sound when the vehicle speed is
greater than 3 mph (5 km/h).
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the
other part can still work and stop you. For good
braking, though, you need both parts working well.
235

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount
of cargo being hauled as soon as it is
possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service as
soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 401.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap
properly installed should turn the light off.

CHECK TIRE PRESSURE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message will display when the
pressure in one or more of the vehicle’s tires need
to be checked. This message will also display
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 your Tire Loading
Information Label. SeeTires on page 454,Loading
Your Vehicle on page 370, andInation - Tire
Pressure on page 460. The DIC display also
shows the tire pressure values for the front and
rear tires by pressing the vehicle information
button. SeeDIC Operation and Displays on
page 245. If the tire pressure is low, the low tire
pressure warning light will come on. SeeTire
Pressure Light on page 238.
DRIVER DOOR OPEN
If the driver’s door is not fully closed and the
vehicle is in a drive gear, this message will display
and a chime will sound. 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 will display when the engine coolant
becomes hotter than the normal operating
temperature. SeeEngine Coolant Temperature
Gage on page 238. 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 will turn back on. You can continue to
drive your vehicle.
If this message continues to appear, have the
system repaired by your dealer as soon as
possible to avoid damage to your engine.
