Cadillac 2004 SRX - Manual (Page 380)

Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation 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 inflation pressure as specified in the
vehicle placard and owner’s manual.
The Certification/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 inflation pressure for your vehicle’s
tire. See
Inflation - Tire Pressure on page 5-68.
For the location of the tire and loading information label,
see
Loading Your Vehicle on page 4-48.
Your vehicle’s TPM system can alert you about a low
tire pressure condition but it does not replace normal tire
maintenance. See
Tire Inspection and Rotation on
page 5-72 and Tires on page 5-58.
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 Identification Codes
Each TPM sensor has a unique identification code.
Any time you replace one or more of the TPM sensors,
the identification 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 first tire/wheel
position, and five minutes overall, to match all four
tire/wheel positions. If it takes longer than one minute,
to match the first tire and wheel, or more than five
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.
