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 ªParts and tools.º
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: 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.)
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.
Do not smoke, cause sparks or allow open flames
around fuel or the battery. Their fumes are
flammable.
Be extremely cautious when working on the
battery. It contains poisonous and corrosive
sulfuric acid.
Do not get under your vehicle with just the body
jack supporting it. Always use automotive jack
stands or other solid supports.
Use eye protection whenever you work on or
under your vehicle where you may be exposed to
flying or falling material, fluid spray, etc.
CAUTION!

NOTICE
Remember that battery and ignition cables carry
high currents or voltages. Be careful of
accidentally causing a short circuit.
Before closing the engine hood, check to see that
you have not forgotten any tools, rags, etc.
Do not drive with the air cleaner removed,
excessive engine wear could result. Also
backfiring could cause a fire in the engine

the transmission could be damaged.
Be careful not to scratch the glass surface with
the wiper frame.
