■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds GPS data to the already included war-
ranty-based Lexus roadside service.
Subscribers can press the “SOS” button to reach a Safety Connect response-
center agent, who can help with a wide range of needs, such as: towing, flat
tire, fuel delivery, etc. For a descript ion of the Roadside Assistance services
and their limitations, please see the Safety Connect Terms and Conditions,
which are available at Lexus.com.
Important! Read this informatio n before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power radio\
transmitter and receiver. It receives and also sends out radio frequency (RF)
signals.
In August 1996, the Federal Commu nications Commission (FCC) adopted
RF exposure guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with the safe ty standards previously set by the fol-
lowing U.S. and internat ional standards bodies.
●ANSI (American National Stan dards Institute) C95.1 [1992]
●NCRP (National Council on Radiation Protection and Measurement)
Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation Protection)
[1996]
Those standards were based on comprehensive and periodic evaluations of
the relevant scientific literature. Over 120 scientists, engineers, and physi-
cians from universities, and governme nt health agencies and industries
reviewed the available body of rese arch to develop the ANSI Standard
(C95.1).
The design of Safety Connect complies wi th the FCC guidelines in addition to
those standards.

6-3. Do-it-yourself maintenance
■Situations in which the tire pressure warning system may not operate properly
●In the following cases, the tire pressure warning system may not operate properly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects th e radio wave signals is installed.
• If there is a lot of snow or ice on the vehi cle, particularly around the wheels or wheel
housings.
• If the tire inflation pressure is extr emely higher than the specified level.
• If wheel without the tire pressure warning valve and transmitter are used.
• If the ID code on the tire pressure warning valves and transmitters is not registered
in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility that generates st rong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
If tire position information is not correctly displayed due to the radio wave conditions,
the display may be corrected by driving and changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could be
extended.
●When tire inflation pressure declines rapidly for example when a tire has burst, the
warning may not function.
■The initialization operation
●Make sure to carry out initialization afte r adjusting the tire inflation pressure.
Also, make sure the tires are cold before carryi ng out initialization or tire inflation pres-
sure adjustment.
●If you have accidentally turned the power switch off during initialization, it is not neces-
sary to manually restart the in itialization again, as initialization will restart automatically
the next time the power switch is turned to ON mode.
●If you accidentally perform initialization when initialization is not necessary, adjust the
tire inflation pressure to the specified leve l when the tires are cold, and conduct initial-
ization again.
■When initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following cases, the set-
tings have not been recorded and the system will not operate properly. If repeated
attempts to record tire inflation pressure settings are unsuccessful, have the vehicle
inspected by your Lexus dealer.
●The initialization message is not displayed on the multi-information display when per-
forming initialization.
●After carrying out the initializat ion procedure, the tire pressure warning light blinks for 1
minute then stays on after driving for 20 minutes.
