2007 Cadillac XLR-V Owner's Manual - Page 421

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 run-flat tire, check with an authorized run-flat tire service center 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. As soon as possible, contact the nearest authorized GM or run-flat servicing facility for inspection and repair or replacement. To locate the nearest GM or run-flat servicing facility, call Roadside Assistance. For phone numbers and Roadside Service details see Roadside Service on page 487. {CAUTION: Run-flat tires are constructed differently than other tires and could explode during improper service. You or others could be injured or killed if you attempt to repair, replace, dismount, or mount a run-flat tire. Let only an authorized run-flat service center repair, replace, dismount, and mount run-flat tires. The valve stems on your run-flat tires have sensors that are part of the Tire Pressure Monitor System (TPMS). See Tire Pressure Monitor System on page 423. These sensors contain batteries which are designed to last for 10 years under normal driving conditions. See your dealer if you ever need to have a wheel replaced, or if the sensors ever need replacement. Notice: Using liquid sealants can damage the tire valves and tire pressure monitor sensors in your vehicle's run-flat tires. This damage would not be covered by warranty. Do not use liquid sealants in your vehicle's run-flat tires. 421
