2004 CADILLAC ESCALADE sensor

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’s
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 illuminate
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. Turn the driver’s or
passenger’s side temperature knob 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.

This message will be displayed if any of the tire monitor
sensors have malfunctioned, or if the tire monitor
sensors have not been programmed, or if the
recommended tire pressures are not programmed.
Press the select button to clear it from the DIC display.
Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added
sound equipment may interfere with the operation
of your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment
that has been added improperly.
Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. See
“Retained Accessory Power (RAP)” underIgnition
Positions on page 2-18.

Tire Pressure Monitor System
The Tire Pressure Monitor (TPM) system uses radio
and sensor technology to check tire pressure levels. If
your vehicle has this feature, sensors are mounted
on each tire and wheel assembly, except the spare tire.
The TPM sensors transmit tire pressure readings to
a receiver located in the vehicle.
When a low tire pressure condition is detected, the TPM
system will display the CHECK TIRE PRESSURE
warning message on the Driver Information Center
(DIC); and at the same time illuminate the low tire
pressure warning symbol. For additional information and
details about the DIC operation and displays seeDIC
Operation and Displays on page 3-51andDIC Warnings
and Messages on page 3-62.
When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is signicantly
under-inated.
You should stop and check your tires as soon as
possible, and inate them to the proper pressure as
indicated on the vehicle’s tire information placard.Driving on a signicantly under-inated tire causes the
tire to overheat and can lead to tire failure.
Under-ination also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability. Each tire, including the spare, should be
checked monthly when cold and set to the
recommended ination pressure as specied in the
vehicle placard and owner’s manual.
The Certication/Tire label or the Tire and Loading
Information label (tire information placard) shows the
size of your vehicle’s original tires and the correct
ination pressure for your vehicle’s tires when they are
cold. SeeInation - Tire Pressure on page 5-74. For
the location of the tire and loading information label, see
Loading Your Vehicle on page 4-50.
Your vehicle’s TPM system can alert you about a low
tire pressure condition but it does not replace normal tire
maintenance. SeeTire Inspection and Rotation on
page 5-78andTires on page 5-65.
Notice:Do not use a tire sealant if your vehicle is
equipped with Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.

TPM Sensor Identication Codes
Each TPM sensor has a unique identication code. Any
time you rotate your vehicle’s tires or replace one or
more of the TPM sensors, the identication codes
will need to be matched to the new tire/wheel position.
Each tire/wheel position is matched to a sensor, by
increasing or decreasing the tire’s air pressure.
The sensors are matched to the tire/wheel positions in
the following order: left front (LF); right front (RF);
right rear (RR) and left rear (LR).
You will have one minute to match the rst tire/wheel
position, and ve minutes overall to match all four
tire/wheel positions. If it takes longer than one minute,
to match the rst tire and wheel, or more than ve
minutes to match all four tire and wheel positions the
matching process stops and you will need to start over.
The TPM sensor matching process is outlined below:
1. Set the Parking brake.
2. Turn the ignition switch to RUN with the engine off.3. Turn the exterior lamp switch from “Off” to “On” four
times within 3 seconds. A double horn chirp will
sound and the TPM low tire warning light will begin to
ash. The double horn chirp and ashing TPM
warning light indicate that the TPM matching process
has started. The TPM warning light should continue
ashing throughout the matching procedure. The
SERVICE TIRE MONITOR message will be
displayed on the Driver Information Center (DIC).
4. Start with the left (driver’s side) front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPM sensor by increasing or decreasing
the tire’s air pressure for 10 seconds, then stop and
listen for a single horn chirp. The single horn chirp
should sound within 15 seconds, conrming that the
sensor identication code has been matched to this
tire and wheel position. If you do not hear the
conrming single horn chirp, you will need to start
over with step number one. To let air-pressure out of
a tire you can use the pointy end of the valve cap, a
pencil-style air pressure gage or a key.
6. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in step 5.
5-76

7. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in step 5.
8. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in step 5.
9. After hearing the conrming horn chirp for the left
rear tire, check to see if the TPM warning light is
still ashing. If yes, turn the ignition switch to OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Certication/Tire label or
the Tire and Loading Information label.
11. Put the valve caps back on the valve stems
The spare tire does not have a TPM sensor. If you
replace one of the road tires with the spare, the CHECK
TIRE PRESSURE message will be displayed on the
DIC screen. This message should go off once you
re-install the road tire containing the TPM sensor. The
SVC TIRE MONITOR message is displayed when
the TPM system is malfunctioning. One or more missing
or inoperable TPM sensors will cause the service tire
monitor message to be displayed. See your dealer
for service.Federal Communications Commission and

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-79andWheel Replacement
on page 5-83for more information.
Make sure the spare tire is stored securely. Push, pull,
and then try to rotate or turn the tire. If it moves,
use the ratchet/wheel wrench to tighten the cable. See
Changing a Flat Tire on page 5-86.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeeScheduled Maintenance
on page 6-5.When rotating your tires, always use the correct rotation
pattern shown here.
Do not include the spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the tire and loading
information label. SeeLoading Your Vehicle on
page 4-50andInation - Tire Pressure on page 5-74,
for more information. Make certain that all wheel
nuts are properly tightened. See “Wheel Nut Torque”
underCapacities and Specications on page 5-124.
If your vehicle has the Tire Pressure Monitor (TPM)
system, the sensors will need to be reset after a
tire rotation is performed. See “TPM Sensor
Identication Codes” underTire Pressure Monitor
System on page 5-75.
