DOITYOURSELF 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 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 543.
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
careful not to touch them. Oil and other fluids may
also be hot.
 If the engine is hot, do not remove the radiator cap or
loosen the drain plugs to prevent burning yourself.
 Do not leave anything that may burn easily, such as
paper or rags, in the engine compartment.
 Do not smoke, cause sparks or allow open flames
around fuel or the battery. Their fumes are
flammable.
 Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or
other solid supports.
 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.

INTRODUCTION
542
Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
 Take care when filling the brake fluid reservoir
because brake fluid can harm your eyes and damage
painted surfaces. If fluid gets in your eyes, flush your
eyes with clean water immediately. If you still feel
uncomfortable with your eyes, go to the doctor.
 Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.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.
 If you spill the fluid, be sure to wash it off with water
to prevent it from damaging the parts or paint.
 Do not overfill automatic transmission fluid and
power steering fluid, or the transmission and power
steering could be damaged.
 Be careful not to scratch the glass surface with the
wiper frame.

jack correctly as shown in the illustrations.
CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:
 Follow jacking instructions.
 Do not put any part of your body under the vehicle
supported by the jack. Otherwise, personal injury
may occur.
 Do not start or run the engine while your vehicle is
supported by the jack.
 Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in “P”. Block
the wheels on the opposite side of the jack up point
if necessary.
 Make sure to set the jack properly in the jack point.
Raising the vehicle with jack improperly positioned
will damage the vehicle or may allow the vehicle to fall
off the jack and cause personal injury.
