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”.
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:

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, radiator and exhaust
manifold will be hot, so be careful not to touch them. Oil
and fluid may also be hot.
Do not smoke, cause sparks or allow open flames
around fuel or the battery. The 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.

Make sure the ignition is off if you work near the engine
and condenser cooling fan or radiator grille. With the
ignition on, the engine and condenser cooling fan will
automatically start to run if the engine coolant
temperature is high or if the air conditioner is on.

Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
failing material, fluid spray, etc.
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.
