However, each regular maintenance as well as day−to−day care is more important than ever before to ensure smooth, trouble−free, safe, and economical driving. It is the owner’s responsibility to make sure the specified maintenance, including general maintenance services, is performed. Note that both the new vehicle and emission control system warranties specify that proper maintenance and care must be performed. See the “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for complete warranty information. General maintenance General maintenance items are those day−to−day care practices that are important to your vehicle for proper operation. It is the owner’s responsibility to ensure that the general maintenance items are performed regularly. These checks or inspections can be done either by yourself or your Lexus dealer. 288 Scheduled maintenance The scheduled maintenance items listed in the “Owner’s Manual Supplement/Scheduled Maintenance” are those required to be serviced at regular intervals. For details of your maintenance schedule, read the “Owner’s Manual Supplement/Scheduled Maintenance”. It is recommended that any replacement parts used for maintenance or for the repair of the emission control system be Lexus supplied. The owner may elect to use non−Lexus supplied parts for replacement purposes without invalidating the emission control system warranty. However, use of replacement parts which are not of equivalent quality may impair the effectiveness of the emission control systems. You may also elect to have maintenance, replacement, or repair of the emission control devices and system performed by any automotive repair establishment or individual without invalidating this warranty. See “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for complete warranty information. MAINTENANCE Where to go for service? GENERAL MAINTENANCE Lexus technicians are well−trained specialists and are kept up to date with the latest service information through technical bulletins, service tips, and in−dealership training programs. They are well informed about the operation of all the systems on your vehicle. Listed below are the general maintenance items that should be performed at the intervals specified. It is recommended that any problem you notice be brought to the attention of your Lexus dealer or qualified service shop for their advice. You can be confident that your Lexus dealer’s service department performs the best job to meet the maintenance requirements of your vehicle. CAUTION Your copy of the repair order is proof that all required maintenance has been performed for warranty coverage. And if any problems should arise with your vehicle while under warranty, your Lexus dealer will promptly take care of it. Again, be sure to keep a copy of the repair order for any service performed on your Lexus. What about do−it−yourself maintenance? Many of the maintenance items are easy to do yourself, if you have a little mechanical ability and a few basic automotive tools. Simple instructions for how to perform them are presented in Section 6. If you are a skilled do−it−yourself mechanic, the Lexus service manuals are recommended. Please be aware that do−it−yourself maintenance can affect your warranty coverage. See your “Owner’s Guide”, “Owner’s Manual Supplement” or “Warranty Booklet” for the details. Make these checks only where adequate ventilation can be obtained if you run the engine. Vehicle exterior Items listed below should be performed from time to time, unless otherwise specified. Tire pressure Check the pressure with a gauge every two weeks, or at least once a month and adjust as shown on the tire pressure label. See page 324 for additional information. Tire surface Check the tires carefully for cuts, damage or excessive wear. See page 326 for additional information. Wheel nuts When checking the tires, make sure to check the nuts for looseness. Tighten them if necessary. 289 MAINTENANCE Tire rotation Vehicle interior Rotate the tires according to the maintenance schedule. (For scheduled maintenance information, please refer to the “Owner’s Manual Supplement/Scheduled Maintenance”.) See page 326 for additional information. Items listed below should be checked regularly, e.g. while performing periodic services, cleaning the vehicle, etc. Fluid leaks Make sure the headlight, stop lights, tail lights, turn signal lights, and other lights are working. Check headlight aim. Check underneath for leaking fuel, oil, water or other fluid after the vehicle has been parked for a while. If you smell fuel fumes or notice any leak, have the cause found and corrected immediately. Lights Service reminder indicators and warning buzzers Check that all service reminder indicators and warning buzzers function properly. Doors and engine hood Steering wheel Check that all doors, including trunk lid, operate smoothly and all latches lock securely. Make sure the engine hood secondary latch secures the hood when the primary latch is released. Check that it has the specified freeplay. Be alert for changes in steering condition, such as hard steering, excessive freeplay or strange noise. Seats Check that all front seat controls such as seat adjusters, seatback recliner, etc. operate smoothly. Check that the head restraints move up and down smoothly and that the locks hold securely in any latched position. Seat belts Check that the seat belt system such as buckles, retractors and anchors operate properly and smoothly. Make sure the belt webbing is not cut, frayed, worn or damaged. 290 MAINTENANCE Accelerator pedal Engine compartment Check the pedal for smooth operation and uneven pedal effort or catching. Items listed below should be checked from time to time, e.g. each time when refueling. Brake pedal Washer fluid Check the pedal for smooth operation and the proper clearance and freeplay. Check the brake booster function. Make sure there is sufficient fluid in the tank. See page 348 for additional information. Brakes Engine coolant level At a safe place, check that the brakes do not pull to one side when applied. Make sure the coolant level is between the “F” and “L” lines on the see−through reservoir when the engine is cold. See page 315 for additional information. Parking brake Check that the pedal has the proper travel and that, on a safe incline, your vehicle is held securely with only the parking brake applied. Automatic transmission “Park” mechanism On a safe incline, check that your vehicle is held securely with the selector lever in “P” position and all brakes released. Radiator, condenser and hoses Check that the front of the radiator and condenser are clean and not blocked with leaves, dirt, or insects. See page 317 for additional information. Battery Check the battery condition by the indicator color. See page 341 for additional information. Brake fluid level Make sure the brake fluid level is correct. See page 322 for additional information. Engine oil level Check the level on the dipstick with the engine turned off and the vehicle parked on a level spot. See page 312 for additional information. 291 MAINTENANCE Power steering fluid level Check the level through the reservoir. The level should be in the “HOT” or “COLD” range depending on the fluid temperature. See page 323 for additional information. Exhaust system If you notice any change in the sound of the exhaust or smell exhaust fumes, have the cause located and corrected immediately. (See “Engine exhaust caution” on page 223.) 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 292 MAINTENANCE If you notice any of these clues, take your vehicle to your Lexus dealer as soon as possible. It probably needs adjustment or repair. EMISSIONS INSPECTION AND MAINTENANCE (I/M) PROGRAMS CAUTION Some states have vehicle emission inspection programs which include OBD (On−Board Diagnostics) checks. Do not continue driving with the vehicle unchecked. It could result in serious vehicle damage and possibly personal injury. The OBD system monitors the operation of the emission control system. When the OBD system determines that a problem exists somewhere in the emission control system, the malfunction indicator lamp comes on. In this case, your vehicle may not pass the I/M test and need to be repaired. Contact your Lexus dealer to service the vehicle. Even if the malfunction indicator lamp does not come on, your vehicle may not pass the I/M test as readiness codes have not been set in the OBD system. Readiness codes are automatically set during ordinary driving. However, when the battery is disconnected or run down, the codes are erased. Also, depending on your driving habits, the codes may not be completely set. Also, if the malfunction indicator lamp had come on recently due to temporary malfunction such as a loose fuel tank cap, your vehicle may not pass the I/M test. The malfunction indicator lamp will go off after taking several driving trips, but the error code in the OBD system will not be cleared unless about 40 trips or more are taken. If your vehicle does not pass the I/M test even the malfunction indicator lamp does not come on, contact your Lexus dealer to prepare the vehicle for re−testing. 293 MAINTENANCE 294
