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 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 cccxliii.
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.
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.

Oil identification mark
The ILSAC (International Lubricant Standardization and
Approval Committee) Certification Mark is added to some oil
containers to help you select the oil you should use.
To ensure excellent lubrication performance for your engine,
“Toyota Genuine Motor Oil” is available, which has been
specifically tested and approved for all Lexus engines.
Please contact your Lexus dealer for further details about
“Toyota Genuine Motor Oil”.
CHECKING THE ENGINE COOLANTLEVEL
1Reservoir cap2Upper line3Lower line
Look at the see through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the “F” and “L” lines on the reservoir. If the level
is low, add the coolant. (For the coolant type, see “Coolant
type selection” described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the “L” line,
add coolant. Bring the level up to the “F” line.
