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 once every 60 seconds while the vehicle is
being driven, and once every 60 minutes if the vehicle
is stationary for more than 15 minutes.
Using the Driver Information Center (DIC), tire pressure
levels can be viewed by the driver. For additional
information and details about the DIC operation and
displays seeSystem Controls on page 3-48and
DIC Warnings and Messages on page 3-57. 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.
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 Tire and Loading Information Label (your vehicle’s
tire information placard) shows the size of your
vehicle’s original tires and their recommended cold
ination pressures. SeeLoading Your Vehicle on
page 4-45, for the location of the tire and loading
information label. Also seeInation - Tire Pressure on
page 5-58.
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 5-63andTires on page 5-51.
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.

CADILLAC SRX 2005 1.G User Guide TPM Sensor Identi�cation Codes
Each TPM sensor has a unique identi�cation code. Any

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 and 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.
