How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they are under-inflated. 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 inflation 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. Re-check 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. Tire Pressure Monitor System If your vehicle has this feature, it is designed to alert you when the system detects a large change in the pressure of one tire. The system cannot alert you before you drive that a tire is low or flat. You must begin driving before the system will work properly. The system works with the brake control system and is designed to detect differences in the tire rotation speeds that are caused by changes in tire pressure. The tire pressure monitoring system does not replace normal tire maintenance, see Tires on page 5-57, Tire Inspection and Rotation on page 5-68 and When It Is Time for New Tires on page 5-69. This light, on the instrument panel cluster, comes on when the tire pressure monitoring system detects a low-tire condition. This light will also come on for a few seconds and then go off when you turn the ignition to ON. This indicates that the tire pressure monitoring system is functioning properly. If the low-tire pressure warning light comes on while driving your vehicle, the system may have detected a low-tire condition. 5-65
