inflation pressure of each tire on the multi-
information display while the tire pressure
warning system determines the position.
8Drive 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
approximately 20 minutes and then drive
the vehicle 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 ou t initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initializat ion 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 accidenta lly turned the power
switch off during initialization, it is not
necessary to manually restart the initial-
ization again, as initialization will restart automatically the next time the power
switch is turned to 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 initiali zation 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 th e initialization pro-
cedure 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 afte r performing initial-
ization, the tire pr essure warning light
blinks for approximately 1 minute and
then illuminates.
If initialization canno t be completed after
performing the above procedure, contact
your Lexus dealer.

warning system after registering the ID
codes. If the system is initialized before
registering the ID codes, the initialized
values will be invalid.
●ID codes can be registered by yourself,
but depending on the driving conditions
and driving environment, registration
may take some time to complete.
■Canceling ID code registration
●To cancel ID code registration after it has
been started, turn the power switch off
before driving the vehicle.
If the vehicle is driven after ID code regis-
tration is started, to cancel registration,
perform the ID code registration start
procedure again and turn the power
switch off before driving.
●If ID code registration has been can-
celed, the tire pressure warning light will
blink for approximately 1 minute when the
power switch is turned to ON mode and
then illuminate. The tire pressure warning
system will be operational when the tire
pressure warning light turns off.
●If the warning light does not turn off even
after several minutes have elapsed, ID
code registration may not have been
canceled correctly. To cancel registra-
tion, perform the ID code registration
start procedure again and then turn the
power switch off before driving.
■If ID codes are not registered properly
●In the following situations, ID code regis-
tration may take longer than usual to be
completed or may not be possible. Nor-
mally, registration completes within
approximately 30 minutes.
• Vehicle is not parked for approximately 20 minutes or more before driving
• 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 tran smitters of your
vehicle over those of other vehicles
• Wheel with tire pressure warning valve and transmitter installed is inside or near
the vehicle
If registration does not complete after driv-
ing for 1 hour or more, perform the ID code registration proced
ure again from the
beginning.
●If the vehicle is reve rsed during registra-
tion, the data up to that point is reset, so
perform the registration procedure again
from the beginning.
●In the following situations, ID code regis-
tration will not be started or was not com-
pleted properly and the system will not
operate properly. Pe rform the ID code
registration procedure again.
• If, when attempting to start ID code regis- tration, the tire pressure warning light
does not blink slowly 3 times.
• If, when the vehicle has been driven for about 20 minutes after performing ID
code registration, the tire pressure warn-
ing light blinks for approximately 1 minute
and then illuminates.
●If ID code registration cannot be com-
pleted after performing the above proce-
dure, contact your Lexus dealer.
