RC F_U Important! Read this information abou t exposure to radio frequency signals
before using Safety Connect;
The Safety Connect system installed in your vehicle is a low-power radio trans-
mitter and receiver. It receives and also sends out radio frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC) adopted RF
exposure guidelines with safety levels for mobile wireless phones. Those guide-
lines are consistent with the safety standards previously set by the following U.S.
and international 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 literatur e. Over 120 scientists, engineers, and physicians from
universities, and government health agen cies and industries reviewed the avail-
able body of research to deve lop the ANSI Standard (C95.1).
The design of Safety Connect complies wi th the FCC guidelines in addition to
those standards. Safety information for Safety Connect

Maintenance and care ■
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 tires not equipped with tire pressure warning valves and tr ansmitters 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 phon e 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 engine swit ch off during initialization, it is not neces-
sary to press the reset switch again as initialization will re start automatically when the
engine switch has been turned to IG NITION ON mode for the next time.●
If you accidentally press the re set switch when initialization is not necessary, adjust the
tire inflation pressure to the specified leve l when the tires are co ld, 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. ●
When operating the tire pres sure warning reset switch, th e tire pressure warning light
does not blink 3 times. ●
After carrying out the initializat ion procedure, the tire pressu re warning light blinks for 1
minute then stays on after driving for 20 minutes.
