'08 MATRIX_U (L/O 0706) Keep your tire inflation pressures at the proper level. The recommended cold tire inflation pressures, tire sizes and the combined weight of occupants and cargo (vehicle capacity weight) are described on page 304 and 308. They are also on the tire and loading information label. You should check the tire inflation pressure every two weeks, or at least once a month. And do not forget the spare! The following instructions for checking tire inflation pressure should be observed: D The pressure should be checked only when the tires are cold. If your vehicle has been parked for at least 3 hours and has not been driven for more than 1.5 km or 1 mile since, you will get an accurate cold tire inflation pressure reading. D Always use a tire pressure gauge. The appearance of a tire can be misleading. Besides, tire inflation pressures that are even just a few pounds off can degrade ride and handling. D Take special care when adding air to the compact spare tire. The smaller tire size can gain pressure very quickly. Add compressed air in small quantities and check the pressure often until it reaches the specified pressure. D Do not bleed or reduce tire inflation pressure after driving. It is normal for the tire inflation pressure to be higher after driving. D Never exceed the vehicle capacity weight. Passenger and luggage weight should be located so that the vehicle is balanced. Tire pressure gauge INSPECTION AND ADJUSTMENT PROCEDURE 1. Remove the tire valve cap. 2. Press the tip of the tire pressure gauge to the tire valve. 3. Read the pressure using the graduations of the gauge. 4. In case the tire inflation pressure is not within the prescribed range, insert the compressed air from the valve. In case of applying too much air, press the center of the valve and release the air to adjust. 281 2008 COROLLA MATRIX from Aug. '07 Prod. (OM12B26U)
