How to Reset Tire Pressure Sensors on 2007 Cadillac DTS Carsby Chris Ward
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
Check the pressure in each tire with a tire gauge and note the pressures for each.
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
Turn the ignition switch to the "Run" position, but do not start the vehicle.
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.
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.

- According to the EPA, low tire pressures can result in premature tire wear and up to a 3 percent reduction in fuel economy. The TPMS will indicate when a tire is at 25 PSI, or 7 PSI lower than the factory-recommended settings. Even a 1 PSI drop in tire pressure can result in a .03 percent reduction in fuel economy. Check your tires' pressure every time you fill your car with gas.
Things You'll Need
