Install the tire valve cap. If the gauge and the air pump are not available, have your vehicle checked by your Toyota dealer. CAUTION Be sure to reinstall the tire valve caps. Without the valve caps, dirt or moisture could get into the valve core and cause air leakage. If the caps have been lost, have new ones put on as soon as possible. Incorrect tire inflation pressure may waste fuel, reduce the comfort of driving, reduce tire life and make your vehicle less safe to drive. If a tire frequently needs refilling, have it checked by your Toyota dealer. CAUTION Keep your tires properly inflated. Otherwise, the following conditions may occur and cause an accident resulting in death or serious injuries. Low tire pressure (underinflation)- D Excessive wear D Uneven wear D Poor handling D Possibility of blowouts from overheated tire. D Poor sealing of the tire bead D Wheel deformation and/or tire separation D A greater possibility of tire damage from road hazards 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 a graduation of the gauge. 4. In case that 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. 266 2004 MATRIX from Oct. '03 Prod. (OM12861U)
