2006 Cadillac STS-V Owner's Manual - Page 376

Run-Flat Tires (STS-V) If your vehicle has run-flat tires, there is no spare tire and no tire changing equipment. Your vehicle also has a Tire Pressure Monitor System (TPMS) which will alert you if there is a loss of tire pressure in any of the tires. See Tire Pressure Monitor System on page 5-67. {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. If a tire goes flat, you will not need to stop on the side of the road to change the tire. You can just keep on driving. The vehicle's run-flat tires can operate effectively with no air pressure for up to 50 miles (80 km) at speeds up to 55 mph (90 km/h). The shorter the distance you drive and the slower the speed, the greater the chance that the tire will not have to be replaced. When a tire is filled with air, it provides a cushion between the road and the wheel. Because you will not have this cushion when driving on a deflated run-flat tire, try to avoid potholes that could damage your wheel and require replacement of it. Some road hazards can damage a tire beyond repair. This damage could occur even before you have driven on the tire in a deflated condition. When a tire has been damaged, or if you have driven any distance on a deflated run-flat tire, check with an authorized run-flat tire service center, as soon as possible, to determine whether the tire can be repaired or should be replaced. To maintain your vehicle's run-flat feature, all replacement tires must be self-supporting tires. To locate the nearest GM or authorized run-flat servicing facility, call Roadside Service. See Roadside Service on page 7-5 for details. 5-64
