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 engine switch is in the “ON” position, it
receives and also sends radio frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels fo r 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 Radi ation Protection and Measurement)
Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on comp rehensive 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 resear ch to develop the ANSI Standard
(C95.1).
The design of the Lexus Link System complies wi th the FCC guidelines in
addition to those standards.

■Lexus Link transceiver antenna
●Use only the supplied or an approved antenna. Unauthorized antennas, modifi-
cations, or attachments could damage the Lexus Link System and may violate
FCC regulations.
CAUTION
■FCC WARNING
Changes or modifications in construction not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equip-
ment.
Radio Frequency Exposure. This device is approved for Mobile Application only
and, to comply with applicable FCC radio frequency exposure regulations, must be
used with a distance of at least 7.9 in. (20 cm) between the antenna and the body of
any person at all time during use.
■Caution regarding interference with electronic devices
Persons using medical devices such as a pacemaker should not touch or come in
close contact with the antenna while the vehicle engine switch is on. Otherwise, the
cellular signals may cause a malfunction in the medical devices.
●Before using an automatic car wash,
disconnect the antenna by unscrewing
it from the roof mount.
When you remove the antenna, make
sure the engine switch is turned off.

4-2. Maintenance
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained speciali sts 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 de aler will promptly take care of it.
CAUTION
■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.
●Battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brain damage. Wash your hands after han-
dling. (P. 333)
●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 thorough ly with soap and water.

Maintenance and care
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.
■When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, inverter, 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 or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
■When working near the electric cooling fan or radiator grille
Be sure the engine switch is in “LOCK”.
With the engine switch is in the “ACC” or “ON” position, the electric cooling fan
may automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 3 2 9 )
■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.
