CONSUMER INFORMATION, REPORTING SAFETY DEFECTS & BINDING ARBITRATION OF WARRANTY CLAIMS 8 5 I035A01JM-AAT CAUTION: Always observe the following: o Check pressures when the tires are cold. (After the vehicle has been parked for at least three hours or hasn't been driven more than one mile (1.6 km) since starting up.) o Check the pressure of your spare tire each time you check the pressure of other tires. o Never overload your vehicle. Be especially careful about overloading if you equip your vehicle with a luggage rack. o Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them. ! CHECKING TIRE INFLATION PRESSURE Check your tires once a month or more. Also, check the tire pressure of the spare tire. How to Check Use a good quality gage to check tire pressure. You can not tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they're underinflated. Check the tire's inflation pressure when the tires are cold. - "Cold" means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the tire and loading information label, no further adjustment is necessary. If the pressure is low, add air until you reach the recommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Recheck the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.
