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.

■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.
• 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 is 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 correctl y 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 press the reset switch again as initialization will restart automatically when the
power switch has been turned to 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 cold, and conduct initial-
ization again.
●While the position of each tire is being de termined and the inflation pressures are not
being displayed on the multi-info rmation display, if the inflation pressure of a tire drops,
the tire pressure warning light will come on.

AVERTISSEMENT
■Précautions relatives aux coussins gonflables SRS
●Si vous avez des difficultés à respirer après le déploiement des coussins gonflables
SRS, ouvrez une porte ou une vitre pour faire entrer de l'air frais, ou bien descendez
du véhicule si cela ne présente pas de danger. Essuyez tout résidu dès que possible
afin d'éviter d'éventuelles irritations de la peau.
●Si les parties renferma nt les coussins gonflables SRS, comme les garnitures du volant
et des montants avant et arrière, sont endommagées ou craquelées, faites-les rem-
placer par votre concessionnaire Lexus.
●Ne placez rien sur le siège du passager avant, comme un coussin par exemple. Cela
a pour conséquence de répartir le poids du passager sur toute la surface du siège, ce
qui empêche le capteur de détecter correctement le poids du passager. En consé-
quence, les coussins gonflables frontaux SR S du passager avant risquent de ne pas se
déployer en cas de collision.
■Modification et mise au rebut des compos ants du système de coussins gonflables
SRS
Ne mettez pas votre véhicule au rebut et ne procédez à aucune des modifications sui-
vantes sans consulter votre concessionna ire Lexus. Les coussins gonflables SRS
peuvent ne pas fonctionner correctement ou se déployer (se gonfler) accidentelle-
ment, provoquant la mort ou de graves blessures.
●Installation, dépose, démontage et réparation des coussins gonflables SRS
●Réparations, modifications, démontage ou remplacement du volant, du tableau de
bord, des sièges ou de leur garnissage, des montants avant, latéraux et arrière, des
rails latéraux de toit, des pa nneaux de porte avant, de la garniture de porte avant ou
des haut-parleurs de porte avant
●Modifications du panneau de porte avant (p ar exemple, perçage d'un trou dans le
panneau)
●Réparations ou modifications des ailes avan t, du pare-chocs avant ou des flancs de
l'habitacle
●Installation d'un protège-calandre (pare- buffle, pare-kangourou, etc.), de chasse-
neige, de treuils ou d'un porte-bagages de toit
●Modifications du système de suspension du véhicule
●Installation d'appareils él ectroniques tels que les ém etteurs/récepteurs radios
mobiles et les lecteurs CD
●Modifications de votre véhicule pour une personne atteinte d'un handicap physique
