LS500h_OM_OM50F42U_(U) Important! Read this information about
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 Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.
 ANSI (American National Stan-
dards Institute) C95.1 [1992]
 NCRP (National Council on Radia-
tion Protection and Measurement)
Report 86 [1986]
 ICNIRP (International Commission
on Non-Ionizing Radiation Protec-
tion) [1996]
Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over
120 scientists, engi neers, and physi-
cians from universi ties, and govern-
ment health agencies and industries
reviewed the available body of
research to develop the ANSI Stan-
dard (C95.1).
The design of Safety Connect com-
plies with the FCC guidelines in addi-
tion to those standards.Safety information for Safety

 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( → P.86)
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( → P.431)
■
Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
■
Tire inflation pressure
●
It may take a few minutes to display the
tire inflation pressure after the power
switch is turned to ON mode. It may also
take a few minutes to display the tire infla-
tion pressure after inflation pressure has
been adjusted.
●
Tire inflation pressu re changes with tem-
perature. The displayed values may also be different from the values measured
using a tire pressure gauge. ■
Situations in which the tire pressure
warning system may not operate prop-
erly ●
In the following cases, the tire pressure
warning system may not operate prop-
erly.
• If non-genuine Lexus wheels are used.
• If a tire has been replaced with a tire that
is not an OE (Original Equipment) tire.
• If a tire has been replaced with a tire that
is not of the specified size.
• If tire chains, etc. are installed.
• An auxiliary-supported run-flat tire is
equipped.
• If a window tint that affects the 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 much higher
than the specified level.
• If wheels not equipped with tire pressure
warning valves and transmitter are used.
• If the ID code on the tire pressure warn-
ing valves and transmitters is not regis-
tered in the tire pressure warning
computer. ●
Performance may be af fected in the fol-
lowing situations.
• When driving near a TV tower, electric
power plant, gas stat ion, radio station,
large display, airport or other facility that
generates strong radi o waves or electri-
cal 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 changing
the location of the vehicle as the radio wave
conditions may change.
●
When the vehicle is stopped, the time
taken for the warning to start or turn off
may be longer.
●
When the inflation pressure of a tire
drops rapidly, for example when a tire has
burst, the warning may not operate.

Vehicle specifications ■
Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment test surfaces of asphalt and
concrete. A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction. ■
Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudd en tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Fede ral Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is prop erly inflated and not
overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
