trol switches and select “Vehicle
Settings”, then press “OK”.
6 Press or of the meter con-
trol switches an d select “TPWS”,
then press “OK”.
7 Press or of the meter con-
trol switches and select “Set Pres-
sure”. Then press and hold “OK”
until the tire pressure warning light
starts blinking.
A message is displaye d on the multi-infor-
mation display. Also, “--” is displayed for
inflation pressure of each tire on the multi-
information display while the tire pressure
warning system determines the position.
8 Drive at approximately 25 mph
(40 km/h) or more for approxi-
mately 10 to 30 minutes.
When initialization is complete, the infla-
tion pressure of each tire will be displayed
on the multi-information display.
Even if the vehicle is not driven at approxi-
mately 25 mph (40 km /h) or more, initial-
ization can be completed by driving for a
long time. However, if initialization does not
complete after driving for 1 hour or more,
park the vehicle in a safe place for approxi-
mately 20 minutes and then drive the vehi-
cle again.
■When initializing
●Initialization is perfor med while driving at a vehicle speed of approximately 25 mph
(40 km/h) or more.
●Make sure to carry out initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initialization or tire inflation
pressure adjustment.
●The tire pressure warning system can be
initialized by yourse
lf, but depending on
the driving conditions and driving envi-
ronment, initialization may take some
time to complete.
■The initialization operation
●If you have accidentally turned the engine
switch off during initialization, it is not
necessary to manually restart the initial-
ization again, as initialization will restart
automatically the next time the engine
switch is turned to IGNITION ON mode.
●If you accidentally perform initialization
when initialization is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold, and conduct
initialization again.
●While the position of each tire is being
determined and the inflation pressures
are not being displayed on the multi-
information display, if the inflation pres-
sure of a tire drops, the tire pressure
warning light will come on.
■If the tire pressure warning system is not
initialized properly
●In the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. Normally,
initialization comple tes within approxi-
mately 30 minutes.
• Vehicle is not driven at approximately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles and
system cannot recognize tire pressure
warning valve and transmitters of your
vehicle over those of other vehicles
If initialization does no t complete after driv-
ing for 1 hour or more, park the vehicle in a
safe place for approximately 20 minutes
and then drive the vehicle again.
●If the vehicle is reversed during initializa-

tion, the data up to that point is reset, so
perform the initialization procedure
again from the beginning.
●In the following situations, initialization
will not be started or was not completed
properly and the system will not operate
properly. Perform the initialization proce-
dure again.
• If, when attempting to start initialization,
the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for
about 20 minutes after performing ini-
tialization, the tire pressure warning light
blinks for approximately 1 minute and
then illuminates.
If initialization cannot be completed after
performing the above procedure, contact
your Lexus dealer.
Every tire pressure warning valve and
transmitter has a unique ID code.
When replacing a tire pressure warn-
ing valve and transmitter, it is necessary
to register the ID code.
When registering the ID codes, per-
form the following procedure.
1 Park the vehicle in a safe place, wait
for approximately 20 minutes, and
then start the engine. ( P.137) 2
Press or of the meter con-
trol switches and select .
3 Press or of the meter con-
trol switches and select “Vehicle
Settings”, and then press “OK”.
4 Press or of the meter con-
trol switches and select “TPWS”,
and then press “OK”.
5 Press or of the meter con-
trol switches and select “Change
Wheel Set”. Then press and hold
“OK” until the tire pressure warning
light starts slowly blinking 3 times.
Then a message will be displayed on the
multi-information display.
When registration is being performed, the
tire pressure warning light will blink for
approximately 1 minute then illuminate and
“--” will be displayed for the inflation pres-
sure of each tire on the multi-information
display.
6 Drive at approximately 25 mph
(40 km/h) or more for approxi-
mately 10 to 30 minutes.
Registration is complete when the tire
pressure warning light turns off and the
inflation pressure of ea ch tire is displayed
on the multi-information display.
Even if the vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more, regis-
tration can be completed by driving for a
long time. However, if registration does not
WARNING
■When initializing the tire pressure
warning system
Do not initialize tire inflation pressure
without first adjusting the tire inflation
pressure to the spec ified level. Other-
wise, the tire pressure warning light may
not come on even if the tire inflation pres-
sure is low, or it may come on when the
tire inflation pressure is actually normal.

Maintenance and care
The recommended cold tire inflation
pressure and tire size are displayed on
the tire and loading information label.

Tire valve Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pressure
gauge onto the tire valve.
3 Read the pressure using the gauge
gradations.
4 If the tire inflation pressure is not at
the recommended level, adjust the
pressure.
If you add too much air, press the
center of the valve to deflate.
5 After completing the tire inflation
pressure measurement and adjust-
ment, apply soapy water to the
valve and check for leakage.
6 Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure
every two weeks, or at least once a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pres-
sure
Driving with incorrect ti re inflation pressure
may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor han-
dling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating, have it
checked by your Lexus dealer.
■Instructions for checking tire inflation
pressure
When checking tire inflation pressure,
observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at
least 3 hours or has not been driven for
