2004 Cadillac XLR Owner's Manual - Page 285

When rotating your vehicle's tires, always use the correct rotation pattern shown here. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the tire and loading information label, see Inflation - Tire Pressure on page 5-57 and Loading Your Vehicle on page 4-32. Vehicles equipped with the Tire Pressure Monitor (TPM) system will need to have the sensors reset after a tire rotation is performed. A special tool is needed to reset the sensor identification codes. See your dealer for service. Make certain that all wheel nuts are properly tightened. See Wheel Replacement on page 5-66 and "Wheel Nut Torque" under Capacities and Specifications on page 5-91. {CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause a crash. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. 5-61
