NOTICE
OWhen other wireless keys (that emit
radio waves) are being used nearby
In addition, excluding the above-men-
tioned, when the charger does not per-
form normally or the operation indicator
light is flashing continuously, it is consid-
ered that the wireless charger is malfunc-
tioning. Contact your Lexus dealer.
QTo prevent failure or damage to data
ODo not bring magnetic cards, such as
credit cards, or magnetic recording
media, etc., close to the charger while
charging, otherwise, data may disap-
pear under the influence of magne-
tism. Also, do not bring precision
instruments such as wrist watches, etc.,
close to the charger, as such objects
may break.
ODo not leave portable devices in the
cabin. The temperature inside the
cabin may become high, when under
the sun, and cause damage to the
device.
QTo prevent 12-volt battery discharge
When the hybrid system is stopped, do
not use the wireless charger for a long
time.

Maintenance and care
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( P.368)
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P.85)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
QRoutine 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.
QTire inflation pressure
OIt 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 inflation pressure after inflation
pressure has been adjusted.
OTire inflation pressure changes with tem-
perature. The displayed values may also
be different from the values measured
using a tire pressure gauge.
QSituations in which the tire pressure
warning system may not operate prop-
erly
OIn the following cases, the tire pressure
warning system may not operate prop-
erly.
• 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.
• 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 extremely
higher than the specified level.
• If wheel without tire pressure warning valves and transmitters 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.
OPerformance may be affected in the fol-
lowing situations.
• Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates
strong 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 correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
OWhen the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
OWhen tire inflation pressure declines rap-
idly for example when a tire has burst, the
warning may not function.

4168-1. Specifications
QTraction 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.
QTemperature 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 sudden tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal 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 properly inflated and not
overloaded.
Excessive speed, underinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
