Maintenance and care
●If you accidentally perform initializa-
tion when initializ ation is not neces- sary, 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 pres -
sures are not being displayed on the
multi-information display, if the infla - tion pressure of a ti re 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. Nor -
mally, initialization completes within
approximately 30 minutes. • Vehicle is not drive n at approximately
40 km/h (25 mph) or more
• Vehicle is driven on unpaved roads • Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit - ters of your vehicle over those of other
vehicles.
• If the vehicle is dri ven in heavy traffic or another situation where other vehi -
cles are driven close by, it may take
time for the system t o recognize the tire pressure warning valve and trans -
mitters of your vehicle over those of
other vehicles.
●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
vehicle again.
●If the vehicle is rev ersed during initial-
ization, the data up to that point is
reset, so perform the initialization pro - cedure again from the beginning.
●In the following situations, initialization will not be started or was not com -
pleted properly and the system will not
operate properly. Pe rform the initial- ization procedure again.
• If, when attempting to start initializa -
tion, the tire pressure warning light
does not blink 3 times.
• If, when the vehicl e has been driven for about 20 minutes after performing
initialization, the tire pressure warning
light blinks for approximately 1 minute and then illuminates.
If initialization cannot be completed after
performing the above procedure, con -
tact any authorized T oyota retailer or
Toyota authorized repairer, or any reli -
able repairer.
Every tire pressure warning valve
and transmitter has a unique ID
code. When replacing a tire pres -
sure warning 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 approxi mately 20 min-
utes, and then start the hybrid
system.
WARNING
■When initializing the tire pres -
sure warning system
Do not initialize tire inflation pressure without first adjusting the tire inflation
pressure to the specified level. Other -
wise, the tire pressu re warning light may not come on even if the tire infla-
tion pressure is lo w, or it may come
on when the tire inf lation pressure is actually normal.

Maintenance and care
●ID codes can be registered by your-
self, but depending on the driving con - ditions and drivi ng environment,
registration may t ake some time to
complete.
●As the tires will be warm when regis -
tration is completed, make sure to allow the tires to c ool before perform-
ing initialization.
■Canceling ID code registration
●To cancel ID code registration after it
has been started, s elect “Identifying
Each Wheel & Position” on the multi-
information display and press and
hold again.
●If ID code registration has been can -
celed, the tire pres sure warning light
will blink for approximately 1 minute when the power switch is turned to
ON and then illuminate. The tire pres -
sure warning syst em will be opera- tional 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 can -
cel registration, perform the ID code
registration start procedure again and then turn the power switch off before
driving.
■If ID codes are no t registered prop-
erly
●In the following situations, ID code
registration may take longer than usual to be completed or may not be
possible. Normally, registration com -
pletes within appr oximately 30 min- utes.
If ID code registrati on is not complete
after driving for app roximately 30 min- utes, continue driving for a while.
• Vehicle is not parked for approxi -
mately 20 minutes or more before driving
• Vehicle is not drive n at approximately
40 km/h (25 mph) or more • Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit - ters of your vehicle over those of other
vehicles
• Wheel with tire p ressure warning valve and transmit ter installed is
inside or near the vehicle
If registration does not complete after
driving for 1 hour or more, perform the
ID code registration procedure again
from the beginning.
●If the vehicle is reversed during regis -
tration, the data up to that point is
reset, so perform the registration pro - cedure again from the beginning.
●In the following si tuations, ID code registration will no t be started or was
not completed properly and the sys -
tem will not operate properly. Perform the ID code regist ration procedure
again.
• If, when attempting to start ID code registration, the ti re pressure warning
light does not blink slowly 3 times.
• If, when the vehicl e has been driven for about 10 minutes after performing
ID code registration, the tire pressure
warning light blinks for approximately 1 minute and the n illuminates.
●If ID code registration cannot be com- pleted after perfo rming the above pro-
cedure, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
Your vehicle is equipped with tire
pressure warning system with the
function to have ID codes regis-
