DO±IT±YOURSELF SERVICEPRECAUTIONS
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 eas\
y 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, se\
e ºParts
and toolsº.
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 compartment ± the engine,
radiator, exhaust manifold and power steering fluid
reservoir, etc. ± will be hot. So be car eful not to touch them.
Oil and other fluids may also be hot.

Do not smoke, cause sparks or allow open flames near 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.

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, or excessive engine wear
could result. Also backfiring could cause a fire in the engine
compartment.

be damaged.

Be careful not to scratch the glass surface with the wiper frame.
