Tire Pressure Monitor System. Cadillac Evoq 2003

For 1990-2009 cars

The Tire Pressure Monitor (TPM) system uses radio and sensor technology to check tire pressure levels. Sensors, mounted on each road wheel, transmit tire pressure readings to a receiver located in the trunk. Tire pressure status and tire pressure warnings are shown on the Driver Information Center (DIC) display. See Driver Information Center (DIC) , for details regarding DIC controls and displays.

The system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry and Science Canada.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This device complies with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device.

Changes or modifications to this system by anyone other than an authorized service facility could void authorization to use this equipment.

If the TPM system detects low tire pressure, below 25 psi (172 kPa), or high tire pressure, above 38 psi (262 kPa), a message, CHECK TIRE PRESSURE, will appear on the Driver Information Center (DIC) display. By pressing the INFO button, the DIC screen will show which tire(s) has the low or high pressure condition. See Inflation - Tire Pressure for information regarding correct tire inflation. If a tire is low, you should stop as soon as possible and check all your tires for damage. If a tire is flat, see If a Tire Goes Flat .

Notice: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors.

Once a low or high tire pressure condition is detected, the TPM system will display the CHECK TIRE MESSAGE each time the engine is started, until the tire(s) are set to the correct inflation pressure.

The Tire-Loading Information Label, which is located on the rear edge of the driver's door, shows the correct inflation pressure for the tires on your vehicle.

The TPM system also allows the driver to check the air pressure status of each road tire using the Driver Information Center (DIC). Each tire's air pressure will be listed individually, in the following order: LF (left front or driver's side front tire), RF (right front or passenger's side front tire), RR (right rear or passenger's side rear tire) and LR (left rear or driver's side rear tire). See Inflation - Tire Pressure for information regarding correct tire inflation. Also, see Driver Information Center (DIC) for information on the DIC controls and displays.

If the DIC display doesn't show tire pressures or the SERVICE TPM SYSTEM message appears, see your dealer for service. The TPM system may not work properly while the compact spare tire is installed.

Anytime you replace one or more tires or rotate your tires, the TPM system will need to be reset. A special tool is needed to reset the sensor identification codes. See your dealer for service.

Your vehicle was delivered from the factory with aluminum valve stem caps. If you ever have to replace the valve stem caps on your vehicle, you should replace them with aluminum or plastic caps.

The TPM system can alert you about a low or high tire pressure condition, but it doesn't replace normal tire maintenance. See Tires .
