LS500_OM_(U)_1810 WARNING■
Caution regarding interference with
electronic devices●
People with implantable cardiac pace-
makers, cardiac resynchronization
therapy-pacemakers or implantable
cardioverter defibrillators should keep
away from the smart access system
with push-button start antennas.
(  P.111)
The radio waves may affect the opera-
tion of such devices. If necessary, the
entry function can be disabled. Ask
your Lexus dealer for details, such as
the frequency of radio waves and tim-
ing of the emitted radio waves. Then,
consult your doctor to see if you
should disable the entry function.●
Users of any electrical medical device
other than implantable cardiac pace-
makers, cardiac resynchronization
therapy-pacemakers or implantable
cardioverter defibrillators should con-
sult the manufacturer of the device for
information about its operation under
the influence of radio waves.
Radio waves could have unexpected
effects on the operation of such medi-
cal devices.
Ask your Lexus dealer for details on dis-
abling the entry function.

Cautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always driv e safely, taking care
to observe your surroundings.
The FCTA system is a supplementary
system that informs the driver of vehicles
approaching from the left and right of the
front of the vehicle.
Do not overly rely on the FCTA system.
Over reliance on the system may lead to
an accident, resulting in death or serious
injury.
The details of the warning display may
differ from the actual traffic conditions.
Although the warnin g display will stop
being displayed after a certain amount of
time, this does not indicate that vehicles
or pedestrians are no longer around your
vehicle.

LS500_OM_(U)_1810 6
Maintenance and care before serious problems arise.
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. (  P.80)
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. (  P.419)
■
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 engine
switch is turned to IGNITION ON mode.
It may also take a few minutes to display
the tire inflation pres sure 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.

460 8-1. Specifications
LS500_OM_(U)_1810 ■
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.
