Handling the radar sensor
Blind Spot Monitor sensors are installed be hind the left and right sides of the rear
bumper respectively. Observe the following to ensure the Blind Spot Monitor can
function correctly.
●
Do not subject a sensor or its surrounding area on the rear bumper to a strong
impact.
If a sensor is moved even slightly off po sition, the system may malfunction and vehi-
cles may not be detected correctly.
In the following situations, have your vehicle inspected by your Lexus dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is sc ratched or dented, or part of them has
become disconnected. ●
Do not disassemble the sensor. ●
Do not attach stickers to the sensor or surrounding area on the rear bumper.●
Do not modify the sensor or surr ounding area on the rear bumper.●
Do not paint the rear bumper any color other than an official Lexus color. ●
Keep the sensors and the surrounding areas
on the rear bumper clean at all times.
If a sensor or its surrounding area on the rear
bumper is dirty or covered with snow, the
Blind Spot Monitor ma y not operate and a
warning message (  P. 5 4 3 ) w i l l b e d i s -
played. In this situation, clear off the dirt or
snow and drive the vehicle with the operation
conditions of the BSM function (  P. 3 6 9 )
satisfied for approximately 10 minutes. If the

Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of the
tire pressure warning valves and transmitters. ■
Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when tire
chains are fitted.

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 frequency (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 safe ty standards previously set by the fol-
lowing U.S. and international standards bodies. ●
ANSI (American National Stan dards Institute) C95.1 [1992]●
NCRP (National Council on Radiation Protection and Measurement)
Report 86 [1986] ●
ICNIRP (International Commission on Non-Ionizing Radiation Protection)
[1996]
Those standards were based on comprehensive and periodic evaluations of
the relevant scientific literature. Over 120 scientists, engineers, and physi-
cians from universities, and governme nt health agencies and industries
reviewed the available body of research to develop the ANSI Standard
(C95.1).
The design of Safety Connect complies wi th the FCC guidelines in addition to
those standards. ■

Maintenance and care
RX450h_U_OM0E013U Check if the treadwear indicators are showing on the tires. Also check the tires
for uneven wear, such as excessive wear on one side of the tread.
Check the spare tire condition and pressure if not rotated.
New tread
Wo r n t r e a d
Treadwear indicator The location of treadwear indicators is shown by a “TWI” or “  ” mark, etc., molded
into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.
Rotate the tires in the order shown. To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is
carried out at the same interval as tire
inspection.
Do not fail to initialize the tire pressure
warning system after tire rotation.Tires Replace or rotate tires in accordance with maintenance schedules and tread-
wear.

488 6-3. Do-it-yourself maintenance
RX450h_U_OM0E013U Your vehicle is equipped with a tire pressure warning system that uses tire pres-
sure warning valves and transmitters to detect low tire inflation pressure before
serious problems arise.
◆ Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and transmitters
must also be installed.
When new tire pressure warning valves and transmitters are installed, new ID
codes must be registered in the tire pressure warning computer and the tire
pressure warning system must be initialized. Have tire pressure warning valve
and transmitter ID codes registered by your Lexus dealer. (  P. 4 8 9 )
◆ Initializing the tire pressure warning system ■
The tire pressure warning system must be initialized in the following circum-
stances: ●
When the tire inflation pressure is changed such as when changing travel-
ing speed. ●
When the tire inflation pressure is changed such as when the tire size is
changed. ●
When rotating the tires
When the tire pressure warning system is initialized, the current tire inflation
pressure is set as the benchmark pressure.Tire pressure warning system ●
The tire pressure detected by the tire
pressure warning system can be dis-
played on the multi-information display. The illustration used is intended as an exam-
ple, and may differ from the image that is
actually displayed on the multi-information
display.●
If the tire pressure drops below a prede-
termined level, the driver is warned by a
screen display and a warning light.
(  P. 5 3 8 ) The illustration used is intended as an exam-
ple, and may differ from the image that is
actually displayed on the multi-information
display.

How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the power switch off. Initialization cannot be performe d while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation pressure
level. (  P. 5 8 9 )Make sure to adjust the tire pressure to the specified cold tire inflation pressure
level. The tire pressure warning system w ill operate based on this pressure level.
Turn the power switch to ON mode.
Select on the multi-information display. (  P. 1 0 9 )
Press or of the meter con-
trol switch, select the “TPMS”
screen and then press and hold
the
until the tire pressure
warning light blinks slowly 3
times. “- -” will be displayed for inflation
pressure of each tire on the multi-
information display while the tire
pressure warning system determines
the position of each tire.
When position of each tire is determined, the inflation pressure of each tire will be
displayed on the multi-information display.
Drive the vehicle at approximately 25 mph (40 km/h) or more for approx-
imately 10 to 30 minutes until the inflat ion pressure of each tire is displayed
on the multi-information display. If tire inflation pressure becomes low before the inflation pressure is displayed, the
tire pressure warning light will come on.
Depending on the vehicle and driving conditions, initializati on may take up to
approximately 1 hour to complete.
◆ Registering ID codes
The tire pressure warning valve and transmitter is equipped with a unique ID
code. When replacing a tire pressure warning valve and transmitter, it is nec-
essary to register the ID code. Have the ID code registered by your Lexus
dealer. 1

When to replace your vehicle’s tires
Tires should be replaced if: ●
The treadwear indicators are showing on a tire. ●
You have tire damage such as cuts, splits, cracks deep enough to expose the fabric, and
bulges indicating internal damage. ●
A tire goes flat repeatedly or cannot be prop erly repaired due to the size or location of
a cut or other damage.
If you are not sure, consult with your Lexus dealer. ■
Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered, the tire
pressure warning system will not work proper ly. After driving for about 20 minutes, the
tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunc-
tion. ■
Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has seldom
or never been used or damage is not obvious. ■
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.■
Maximum load of tire
Check that the maximum load of the replacem ent tire is greater than 1 /2 of the Gross
Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is
greater.
For the GAWR, see the Certification Label. For
the maximum load of the tire, see the load limit
at maximum cold tire inflation pressure men-
tioned on the sidewall of the tire. (  P. 5 9 4 )
