Question about 2005 Cadillac STS
Service Tire Monitor means that one or more of your tires are underinflated, causing an out of balance condition that it can detect through the wheel speed sensors.
The code should be covered in your manual, to tell you how to reset it after the tires are inflated evenly to manufacturer's specifications.
I would check the sizes of all your tires to verify that they are the same type and size recommended by Cadillac. Also, check the tire inflation in all 4 tires to make sure they are even.
Then, follow the instructions in your manual on how to turn the 'Service Tire Monitor' light off.
If you don't have a manual, you might go to the Cadillac.com website and look under 'owners' and you can sign on to Yahoo! and get a free manual downloaded to your computer for viewing or printing, I believe.
It will come back on if the tires are unevenly inflated as you go down the road several miles.
Ford Windstars, also, have this feature. A lot of newer cars past the year 2000 have this feature which helps you to monitor the pressures and avoid getting a flat tire on a long trip.
Good luck travelling in your first Cadillac.
I have 3 Cadillacs at my disposal, a 1976 Seville, a 1990 Deville, and a 1997 Deville Limo and I love all of them, although the 1976 and 1990 need paint jobs here in Pennsylvania's harsh weather.
