■FCC WARNING
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
Radio Frequency Radiation Exposure. This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equipment and meets the FCC radio fre-
quency (RF) Exposure Guidelines in Supplement C to OET65. This equipment has
very low levels of RF energy that it de emed to comply without maximum permissive
exposure evaluation (MPE). But it is desirable that it should be installed and oper-
ated with at least 7.9 in. (20 cm) and more between the radiator and person’s body
(excluding extremities: hands, wrists, feet and legs).
This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter.

Safety information for Safety Connect
Important! Read this information before using Safety Connect.
■ Exposure to radio frequency signals
The Safety Connect sy stem installed in your vehicle is a low-power
radio transmitter and receiver. It receives and also sends out radio fre-
quency (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 pre-
viously set by the following U.S. and international standards bodies.
● ANSI (American National Standards Institute) C95.1 [1992]
● NCRP (National Council on Radiation Protection and Measure-
ment) Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]

5-2. Steps to take in an emergency
The tire pressure warning system may be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies are nearby.
●If a radio set at similar frequency is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, particularly around the wheels or
wheel housings.
●If non-genuine Lexus wheels are used (Even if you use Lexus wheels, the tire
pressure warning system may not work properly with some types of tires.)
●If tire chains are used.
■If the tire pressure warning light comes on after flashing frequently for 1 minute
If the tire pressure warning light comes on after flashing frequently for 1 minute
when the “POWER” switch is turned to ON mode, have it checked by your Lexus
dealer.
■Customization that can be configured at Lexus dealer
The vehicle speed linked seat belt reminder buzzer can be disabled. 
(Customizable features P. 5 7 2 )
CAUTION
■When the electric power steering system warning light comes on
The steering wheel may become extremely heavy. 
If the steering wheel becomes heavier than usual when operating, hold firmly and
operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change
it with the spare tire and have the flat tire repaired by the nearest Lexus dealer.
