THEFT PREVENTION LABELS
SV61011
Your new vehicle carries theft prevention labels which are
approximately 47 mm (1.85 in.) by 12 mm (0.47 in.).
The purpose of these labels is to reduce the incidence of
vehicle thefts by facilitating the tracing and recovery of parts
from stolen vehicles. The label is designed so that once it is
applied to a surface, any attempt to remove it will result in
destroying the integrity of the label. Transferring these labels
intact from one part to another will be impossible.
NOTICE
You should not attempt to remove the theft preventionlabels as it may violate certain state or federal laws.

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 ªParts and toolsº on page 320.
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 the ignition is off if you work near the electric
cooling fan or radiator grille. With the ignition on, the
electric cooling fan may automatically start to run if
the air conditioning is on and/or if the coolant
temperature is high.

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

Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.
