The Cadillac DTS may be equipped with a tire pressure monitoring system, or TPMS. It detects abnormal tire pressure in each tire and alerts the driver by displaying a message on the driver information center, or DIC. When this happens, the tire's pressure will need to be adjusted and the system will need to be reset. Once the tire pressure is correct and set to factory specs, it only takes a few seconds to reset the system.

Correcting Tire Pressure

Step 1

Check the pressure in each tire with a tire gauge and note the pressures for each.

Step 2

Get the recommended tire pressure from the sticker on the driver door sill.

Adjust the pressure in each tire as necessary to ensure each tire is set to factory-recommended specifications. Add air with an air compressor or let some of the air out with the back end of the tire gauge as required.

Resetting the System

Step 1

Turn the ignition switch to the "Run" position, but do not start the vehicle.

Step 2

Depress the vehicle information button repeatedly until the "PRESS Set/Reset TO RESET TIRE SYSTEM" message displays in the instrument-panel-mounted driver information center interface.

Step 3

Depress and hold the DIC Set/Reset button for five seconds. The display will now show "TIRE PRESSURE SYSTEM RESET."

Turn the key to the "Off" position. The system is now reset and the vehicle is ready to be driven.
