 Safety information for the Lexus Link System
Important! Read this information before using the Lexus Link System. ■Exposure to radio frequency signals
The Lexus Link System installed in your vehicle is a low power ratio trans-
mitter and receiver. When the “POWER” switch is in the ON mode, it
receives and also sends radio frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for mobile wireless
phones. Those guidelines are consistent with the safety standards previ-
ously set by both U.S. and international standards bodies.
● ANSI (American National Standards Institute) C95.1 [1992]
● NCRP (National Council on Radiation Protection and Measurement)
Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on comprehensive and periodic evaluations
of the relevant scientific literature. Over 120 scientists, engineers, and
physicians from universities, government health agencies, and industry
reviewed the available body of research to develop the ANSI Standard
(C95.1).
The design of the Lexus Link System complies with the FCC guidelines in
addition to those standards.

■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialists and are kept up to date with the
latest service information. They are well informed about the operations of all
systems on your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been
performed is under warranty coverage. If any problem should arise while your
vehicle is under warranty, your Lexus dealer will promptly take care of it.
CAUTION
■If your vehicle is not properly maintained
It could result in serious damage to the vehicle and possible serious injury or death.
■Hazardous materials
●Engine exhaust, some of its constituents, and a wide variety of automobile com-
ponents contain or emit chemicals known to the State of California to cause can-
cer and birth defects and other reproductive harm. Work in a well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by compo-
nent wear contain or emit chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm. Avoid exposure and wash
any affected area immediately.
●12 volt battery posts, terminals and related accessories contain lead and lead
compounds which are known to cause brain damage. Wash your hands after
handling. (→P.  4 4 7 )
●Used engine oil contains chemicals that have been shown to cause cancer in lab-
oratory animals. Avoid prolonged and repeated contact. Always protect your
skin by washing thoroughly with soap and water.

CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions.
■When working on the engine compartment
●Make sure that the indicator on the “POWER” switch and the “READY” indicator
are both off.
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, power control unit, radiator, exhaust manifold,
etc. right after driving as they may be hot. 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 expose an open flame to fuel. Fuel fumes are flam-
mable.
■When working near the electric cooling fan or radiator grille
Be sure the “POWER” switch is OFF.
With the “POWER” switch in ON mode, the electric cooling fan may automatically
start to run if the air conditioning is on and/or the coolant temperature is high. 
(→ P.  4 4 5 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also a backfire could cause a fire in the engine compartment.
