MAINTENANCE Tire inflation pressure Check the pressure with a gauge every two weeks, or at least once a month and adjust as shown on the tire and loading information label. See page 657 for additional information. Tire surface Check the tires carefully for cuts, damage or excessive wear. See page 671 for additional information. Tire rotation Rotate the tires according to the maintenance schedule. (For scheduled maintenance information, please refer to the "Owner's Manual Supplement / Scheduled Maintenance".) See "Rotating tires" on page 670. DOES YOUR VEHICLE NEED REPAIRING? Be on the alert for changes in performance and sounds, and visual tip-offs that indicate service is needed. Some important clues are: D Engine missing, stumbling, or pinging D Appreciable loss of power D Strange engine noises D A fluid leak under the vehicle (However, water dripping from the air conditioning after use is normal.) D Change in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked immediately.) D Flat-looking tires, excessive tire squeal when cornering, uneven tire wear D Vehicle pulls to one side when driving straight on a level road D Strange noises related to suspension movement D Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches floors, vehicle pulls to one side when braking D Engine coolant temperature continually higher than normal If you notice any of these clues, take your vehicle to your Lexus dealer as soon as possible. It probably needs adjustment or repair. 611
