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.
Registering ID codes

2Press or of the meter
control switches on the steering
wheel and select .
3 Press or of the meter
control switches and select

until the tire pressure warning
light starts slowly blinking 3
times.
The change wheel set mode is acti - vated and registration is started.
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 illumi - nate and “--” will be displayed for the
inflation pressure o f each tire on the
multi-information display.
6 Drive straight (with occasional
left and right turns) at approxi -
mately 40 km/h (25mph) or
more for approximately 10 to 30
minutes.
When registration is completed, the tire
pressure warning light will go off and
the inflation pressure of each tire will be displayed on the multi-information dis -
play.
Even if the vehicle is not driven at approximately 40 k m/h (25 mph) or
more, registration c an be completed by
driving for a long ti me. However, if reg- istration does not complete after driving
for 1 hour or more, perform the proce-
dure again from the beginning.

ing system. ( →P.523)
■When registering ID codes
●ID code registration is performed
while driving at a vehicle speed of
approximately 40 km/h (25 mph) or more.
●Before performing ID code registra -
tion, make sure that no wheels with tire pressure warning valve and trans -
mitters installed ar e near the vehicle.
●Make sure to initialize the tire pres-
sure warning system a fter registering
the ID codes. If t he system is initial- ized before registering the ID codes,
the initialized val ues will be invalid.

been registered, no change will
be made when selecting this
function in the menu.
 Only a change between both
registered wheel set is possible,
mixing between these wheel sets
is not supported.
■How to change between wheel

light turns on after flashing for 1 minute.
After 2 minutes, regi stration of a sec-
ond wheel set is being performed. The
tire pressure warning light will turn off
and “--” will be displayed for the inflation
pressure of each tir e on the multi-infor-
mation display.
6 Initialize the tire pressure warn-
ing system. ( →P.523)
If the tire inflation pressure settings for the installed tires c hange, initialization
operations are require d, but if the tire
inflation pressure settings are the same, initialization is not required.
Drive straight (with occasional left
and right turns) at approximately 40
