INTRODUCTION DO-IT-YOURSELF SERVICE PRECAUTIONS If you perform maintenance yourself, be sure to follow the correct procedure given in this Section. You should be aware that improper or incomplete servicing may result in operating problems. Performing do-it-yourself maintenance during the warranty period may affect your warranty coverage. Read the separate Lexus Warranty statement for details and suggestions. This Section gives instructions only for those items that are relatively easy for an owner to perform. As explained in Section 5, there are still a number of items that must be performed by a qualified technician with special tools. For information on tools and parts for do-it-yourself maintenance, see "Parts and tools" on page 625. Utmost care should be taken when working on your vehicle to prevent accidental injury. Here are a few precautions that you should be especially careful to observe: CAUTION D When the engine is running, keep hands, clothing, and tools away from the moving fan and engine drive belt. (Removing rings, watches, and ties is advisable.) D Right after driving, the engine compartment - the engine, radiator, exhaust manifold and power steering fluid reservoir, etc. - will be hot. So be careful not to touch them. Oil and other fluids may also be hot. D If the engine is hot, do not remove the radiator cap or loosen the drain plugs to prevent burning yourself. D Do not smoke, cause sparks or allow open flames around fuel or the battery. Their fumes are flammable. D Do not get under your vehicle with just the body jack supporting it. Always use automotive jack stands or other solid supports. D Be sure that the ignition is off if you work near the electric cooling fans or radiator grille. With the ignition on, the electric cooling fans will automatically start to run if the engine coolant temperature is high and/or the air conditioning is on. 622
