2005 Cadillac CTS Owner's Manual - Page 356

Run-Flat Tires (CTS-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: Special tools and procedures are required to service a run-flat tire. If these special tools and procedures aren't used you or others could be injured and your vehicle could be damaged. Always be sure the proper tools and procedures, as described in the service manual, are used. To order a service manual see Service Publications Ordering Information on page 7-12. {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. Don't 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. See Run-Flat Tires (CTS-V) on page 5-61 and Tire Pressure Monitor System (CTS-V) on page 5-65, for additional information. Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers. 5-76
