2006 Cadillac STS Owner's Manual - Page 394

If a tire goes flat, and your vehicle has a spare tire, see Changing a Flat Tire (STS Only) on page 5-83. This information shows you how to use your vehicle's tire changing equipment and how to change a flat tire safely. Run-Flat Tires (STS-V) If your vehicle has run-flat tires, there is no spare tire and no tire changing equipment. Run-flat tires can operate effectively with no air pressure for a limited distance and speed. Your vehicle also has a Tire Pressure Monitor (TPM) which will alert you if there is a loss of tire pressure in any of the tires. These tires perform so well without any air pressure that a Tire Pressure Monitor (TPM) is used to alert you when there is a low tire condition. {CAUTION: Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. Use the jack provided with your vehicle only for changing a flat tire. {CAUTION: When the low tire warning light is displayed on the instrument panel cluster, your vehicle's handling capabilities will be reduced during severe maneuvers. If you drive too fast, you could lose control of your vehicle. You or others could be injured. Do not drive over 55 mph (90 km/h) when the low tire warning light is displayed. Drive cautiously and check your tire pressures as soon as you can. 5-82
