light CADILLAC ESCALADE EXT 2007 3.G Repair Manual

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.
221

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.
222

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, seeHeated Seats on page 10
orHeated and Cooled Seats on page 11.
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.
223

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, etc.,
may affect the performance of the heating and
air conditioning system. Check with your
dealer before adding equipment to the outside
of your vehicle.
Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that
something is wrong before it becomes serious
enough to cause an expensive repair or
replacement. Paying attention to your warning
lights and gages could also save you or others
from injury.Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As
you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they
are working. If you are familiar with this section,
you should not be alarmed when this happens.
Gages can indicate when there may be or is
a problem with one of your vehicle’s functions.
Often gages and warning lights work together
to let you know when there is a problem with
your vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to do
repairs can be costly – and even dangerous.
So please get to know your warning lights and
gages. They are a big help.
Your vehicle also has a Driver Information Center
(DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 243.
225

Safety Belt Reminder Light
When the key is turned to RUN or START, a
chime will sound for several seconds to remind
people to buckle their safety belts. The driver
safety belt light will also come on and stay on for
several seconds. Then it will ash for several
more. You should buckle your seat belt.
This chime and light
will be repeated if the
driver remains
unbuckled and the
vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor
the light will come on.
SeePassenger Sensing System on page 78for
more information.
Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN
or START, a chime will sound for several seconds
to remind the front passenger to buckle their
safety belt. This would only occur if the passenger
airbag is enabled. SeePassenger Sensing
System on page 78for more information. The
passenger safety belt light will also come on and
stay on for several seconds, then it will ash
for several more.
This chime and light
will be repeated if
the passenger remains
unbuckled and the
vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
228

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical system
for malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensors, the airbag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag
System on page 67.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds. Then
the light should go out.
This means the system
is ready.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are
driving, your airbag system may not work
properly. Have your vehicle serviced right away.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to
RUN. If the light does not come on then, have
it xed so it will be ready to warn you if there is
a problem.
229

Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your overhead console has a passenger airbag
status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal airbag.If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is enabled
(may inate).
{CAUTION:
If the on indicator comes on when you
have a rear-facing child restraint installed
in the right front passenger’s seat, it means
that the passenger sensing system has not
turned off the passenger’s frontal airbag.
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.

Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint,
no system is failsafe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 78for more on this,
including important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag readiness
light ever come on together, it means
that something may be wrong with the
airbag system. If this ever happens, have
the vehicle serviced promptly, because
an adult-size person sitting in the right
front passenger seat may not have the
protection of the frontal airbag. See
Airbag Readiness Light on page 229.
231

Charging System Light
The charging system
light will come on briey
when you turn the
ignition to the START
position, as a check to
show you it is working.
The light 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 Driver Information
Center (DIC) will also display the SERVICE
BATTERY CHARGING SYSTEM message. See
DIC Warnings and Messages on page 248
for 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 the 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.
232

If the warning light comes on and a chime sounds
there could be a brake problem.
Have your brake system inspected right away.
This light may also come on due to low brake uid.
SeeBrakes on page 433for more information.
This light should come on briey when you turn
the ignition key to RUN. If it does not come
on then, have it xed so it will be ready to warn
you if there is a problem.If the light comes on while you are driving, pull
off the road and stop carefully. You may notice
that the pedal is harder to push or may go closer
to the oor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 378.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
