Safety information for Safety Connect
Important! Read this information 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 fre-
quency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for 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 Stan dards 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]

HS250h_U_75033U(Canada)Those standards were based on comprehensive and periodic evalua-
tions of the relevant scientific literature. Over 120 scientists, engineers,
and physicians from universities, and government health agencies and
industries reviewed the available body of research to develop the
ANSI Standard (C95.1).
The design of Safety Connect complies with the FCC guidelines in
addition to those standards.

■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty
surfaces and let them dry. Excellent results are obtained by keeping the carpet as
dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid bat-
tery (traction battery) air vents, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to malfunc-
tion or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(→ P. 1 0 6 )
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the
windshield, obstructing the driver’s view and leading to an accident, resulting in
death or serious injury.

they may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes into
contact with electrical components such as the audio system above or under the
floor of the vehicle. Water may also cause the body to rust.
■Cleaning the inside of the rear window
