Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque" under Capacities and Specifications on page 498. {CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. 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 needed, to get all the rust or dirt off. See Changing a Flat Tire on page 464. When rotating P235/50R17 size tires or 255/45ZR18 size tires, always use the correct rotation pattern shown here. If your vehicle has a compact spare tire, do not include the compact spare tire in the tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. Vehicles that have the Tire Pressure Monitor System (TPMS) will need to have the TPMS sensors reset after a tire rotation, see Tire Pressure Monitor System on page 433. 439
