2004 CADILLAC SRX sensor

The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to.
Notice:Do not repeatedly brake or accelerate
heavily when the TCS is off. You could damage your
vehicle’s driveline.
When the TCS is switched off on AWD vehicles, you
may still feel the system working. This is normal
and necessary with the AWD hardware on your vehicle.
You should turn the system off if your vehicle ever
gets stuck in sand, mud or snow and rocking the vehicle
is required. See “Rocking Your Vehicle” underIf You
Are Stuck: In Sand, Mud, Ice or Snow on page 4-44for
more information. See alsoWinter Driving on page 4-40
for information on using TCS when driving in snowy
or icy conditions.
To turn the system off,
press the TC (traction
control) button located
near the shift lever.If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. Press the TC button again to
turn the system back on. If you press and hold the
TC button for ve seconds, the Stabilitrak
®system and
the traction control system will turn off. Press the
TC button again to turn Stabilitrak
®back on. For more
information, seeStabilitrak®System on page 4-11.
Magnetic Ride Control
Your vehicle may have Magnetic Ride Control that
automatically adjusts the ride of your vehicle.
Automatic ride control is achieved through a computer
used to control and monitor the suspension system.
The controller receives input from various sensors
to determine the proper system response. If the
controller detects a problem within the system, the DIC
will display a Service Suspension System message.
SeeDIC Warnings and Messages on page 3-64
for more information. See your dealer for service.

Tire Pressure Monitor System
Your vehicle may have this feature. 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 for the compact spare tire and wheel.
Tire pressure readings are sent 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, on the instrument panel cluster. For additional
information and details about the DIC operation and
displays seeSystem Controls on page 3-51and
DIC Warnings and Messages on page 3-64.
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 (your vehicle’s tire information placard)
shows the size of your vehicle’s original tires and the
recommended cold ination pressure for your vehicle’s
tire. SeeInation - Tire Pressure on page 5-68. For
the location of the tire and loading information label, see
Loading Your Vehicle on page 4-47.
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 5-71andTires on page 5-61.
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 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/wheel positions the
matching process stops and you will need to start over.
The TPM matching process is outlined below:
1. Set the Parking brake.
2. Turn the ignition switch to ON with the engine off.
3. Using the Remote Keyless Entry (RKE) transmitter,
lock and unlock the vehicle’s doors.
4. Press the lock and unlock buttons, at the same
time, on the RKE transmitter. A single horn chirp
will sound, indicating that the TPM system is ready,
and the sensor matching process can begin.5. Start with the left (driver’s side) front tire.
6. Remove the valve cap from the valve stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for ve seconds,
or until a horn chirp sounds. The horn chirp,
which may take up to 30 seconds, conrms that the
sensor identication code has been matched to
this tire position. To decrease the tire’s air-pressure
use the pointy end of the valve cap, a pencil-style
air pressure gage or a key.
7. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 6.
8. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 6.
9. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 6.
10. After hearing the conrming double horn chirp, for
the left rear tire, exit the matching process by
turning the ignition switch to OFF.
11. Set all four tires to the recommended air pressure
level as indicated on the tire and loading information
label.
12. 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 Service
Tire Monitor 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 Service
Tire Monitor message is also 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.

Tire Inspection and Rotation
The tires on your vehicle are different sizes front to rear.
Due to this, your tires should not be rotated. Each tire
and wheel should be used only in the position it is in.
Check your tires and wheels regularly for unusual wear
and damage. Also see,Scheduled Maintenance on
page 6-4,When It Is Time for New Tires on page 5-72
andWheel Replacement on page 5-76.
