Tires: 6 INSPECTION AND MAINTENANCE • Recommended Cold Tire Inflation Pressure of Original Tires • Size of Compact Spare Tire • Recommended Cold Tire Inflation Pressure of Compact Spare Tire Recommended Cold Tire Inflation Pressures Front Tires Rear Tires Compact Spare Tire 230 kPa 33 psi 230 kPa 33 psi 420 kPa 60 psi specification when the vehicle is driven outside in very cold temperature. If you adjust the tire pressure in a garage that is warmer than the outside temperature, you should add 1 psi to the recommended cold tire inflation pressure for every 10°F difference between garage temperature and outside temperature. Measuring Air Pressure Use the following steps to achieve proper tire inflation: 1) Identify the recommended tire pressure on the vehicle's Tire and Loading Information Label or in the owner's manual. 2) Remove the valve cap from the tire valve stem. 3) Using a reliable pressure gauge, measure the tire inflation pressure by pressing the tire gauge firmly onto the valve to get a pressure measurement. Remember that inflation pressures should be checked when the tires are "cold", meaning before they have been driven one mile or after sitting for three hours or more allowing the tire to cool to ambient air temperature. 4) If the air pressure is too high, slowly release the air by pressing on the tire valve stem with the edge of the tire gauge until you reach the correct pressure. 5) If the air pressure is too low, fill the tire with air at a service station until it reaches the recommended pressure. 6) Make sure all tires have the same air pressure (unless the owner's manual indicates otherwise). WARNING • Air pressures should be checked when the tires are cold or you may get inaccurate readings. • Check the inflation pressure from time to time while inflating the tire gradually, until the specified pressure is obtained. • Never underinflate or overinflate the tires. Underinflation can cause unusual handling characteristics or can cause the rim to slip on the tire bead, resulting in an accident or damage to the tire or rim. Underinflation can also cause tires to overheat, leading to tire failure. Overinflation can cause the tire to burst, resulting in personal injury. Overinflation can also cause unusual handling characteristics which may result in an accident. NOTE: The tire inflation pressure will change due to changes in atmospheric pressure, temperature or tire temperature when driving. To reduce the chance that the low tire pressure warning light will come on due to normal changes in temperature and atmospheric pressure, it is important to check and adjust the tire pressures when the tires are cold. Tires that appear to be at the specified pressure when checked after driving, when the tires are warm, could have pressure below the specification when the tires cool down. Also, tires that are inflated to the specified pressure in a warm garage may have pressure below the 9-27 80J22-03E
