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 ignition 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.
● ANIS (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 ignition is on. Otherwise, the cellu-
lar 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 ignition is turned off.

Maintenance and care
■Tire pressure warning system certificationFor vehicles sold in the U.S.A.
NOTE:
This device complies with Part 15 of the FCC Rules. Operation is subject to the fol-
lowing two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
NOTICE:
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installa-
tion. This equipment generate s, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful inter-
ference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful inter-
ference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
●Reorient or relocate the receiving antenna.
●Increase the separation between the equipment and receiver.
●Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
●Consult the dealer or an experienced radio/TV technician for help.
FCC WARNING:
Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
For vehicles sold in Canada
NOTE:
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must a ccept any interference, including interfer-
ence that may cause undesired operation of the device.

When trouble arises

5-2. Steps to take in an emergency
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
■The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such as natural air
leaks or tire inflation pressure changes caused by temperature. In this case, adjust-
ing the tire inflation pressure will turn off the warning light.
■When a tire is replaced with a spare tire
The spare tire is also equipped with the tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare
tire is low. If a tire goes flat, even though the flat tire is replaced with the spare tire,
the warning light does not turn off. Replace the spare tire with the repaired tire and
adjust the proper tire inflation pressure. The warning light will turn off after a few
minutes.
■If the tire pressure warning system is inoperative
The tire pressure warning system may become inoperative in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmitters are used.
●If the ID code on the tire pressure warning valves and transmitters is not regis-
tered.
●If electronic devices or facilities using similar radio wave frequencies are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If the tire pressure warning select switch is set to a different tire setting.
●If there is a lot of snow or ice on the vehicle, in particular around the wheels or
wheel housings.
●If non-genuine Lexus wheels are used.
●If tire chains are used.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or higher.
●If the tire is in a location subject to poor radio wave signal reception.
