3186-3. Do-it-yourself maintenance
7Drive straight (with occa-
sional left and right turns) at
approximately 25 mph (40
km/h) or more for approxi-
mately 10 to 30 minutes.
When wheel position registration is
complete, a message indicating
that registration has been com-
pleted and the inflation pressure of
each tire will be d isplayed on the
multi-information display.
Even if it is not possible to drive
continuously at a pproximately 25
mph (40 km/h) or more, registration
can be completed by driving for a
long time. However, if registration
does not complete a fter driving for
1 hour or more, park the vehicle in
a safe place and leave it with the
engine switch in ON for approxi-
mately 15 minute s or more, and
then perform the dr iving procedure
again.
■When performing wheel posi-
tion registration
●Normally, wheel position registra-
tion can be completed within
approximately 30 minutes.
●Wheel position registration is per-
formed while driving at a vehicle
speed of approximately 25 mph
(40 km/h) or more.
■Wheel position registration pro-
cedure
●If the engine switch is turned off
while registering the wheel posi-
tion, the next time the engine
switch is turned to ON, the wheel
position registr ation will resume
and it will not be necessary to
restart the procedure.
●While the position of each wheel is
being determined and the inflation
pressures are not being dis-
played, if the infl ation pressure of
a tire drops, the tire pressure
warning light will come on.
■If the wheel position cannot be
registered easily
●In the following situations, wheel
position registration may take lon-
ger than usual to be completed or
may not be possible.
• Vehicle is not dr iven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• If wheel position registration does
not complete after driving for 1
hour or more, park the vehicle in a
safe place for a pproximately 15
minutes and then drive the vehicle
again.
●If the vehicle is reversed during
wheel position registration, all
data collected unt il then will be
cleared. Perform driving again.
In the following situations, it will
be necessary to perform the tire
inflation pressure setting proce-
dure of the tire pressure warning
system.
 When the specified tire infla-
tion pressure has changed,
such as due to carried load,
etc.
 When the tire inflation pres-
sure is changed such as
when the tire size is changed.
If the tire inflation pressure has
been adjusted to the specified
level, perform the tire inflation set-
ting procedure by selecting speci-
fied inflation pressure on the
multi-information display.

when tires other than the specified
size are used, etc., set the tire infla-
tion pressure using the current
pressure. Make sure to adjust the
tire inflation pressure of each tire to
the appropriate level before per-
forming tire pressure setting. The
tire pressure warning system oper-
ates based on this tire inflation
pressure.

Make sure to adjust the tire infla-
tion pressure of each tire to the
appropriate level before perform-
ing tire pressure setting. Other-
wise, the tire pressure warning
light may not illumi nate even if the
tire inflation pressure drops or
may illuminate even though the
tire inflation pressure is normal.

■Warning performance of the tire
pressure warning system
●When performing the tire pressure
setting using the current tire infla-
tion pressure, the warning timing
of the tire pressure warning sys-
tem will vary according to the con-
ditions under which tire pressure
setting was performed. Therefore,
a warning may be output even if
the tire inflation pressure drops
slightly or if the ti re inflation pres-
sure increases above that when
the tire inflation pressure was set.
●Make sure to per form the tire
pressure setting p rocedure after
adjusting the tire inflation pres-
sure. Also, make sure the tires are
cold before performing the tire
pressure setting procedure or
adjusting the tire inflation pres-
sure.

■Tire inflation pressure setting
procedure
●If the engine switch is turned off
while setting the tire inflation pres-
sure, the next time the engine
switch is turned to ON, the setting
procedure will resume and it will
not be necessary to restart the
procedure.
●If the tire inflation pressure setting
procedure is started unnecessar-
ily, adjust the tire inflation pres-
sure to the specified level with the
tires cold and then perform setting
by selecting a specified tire infla-
tion pressure, or p erform the tire
inflation pressure setting proce-
dure with the current tire inflation
pressure.
■If the tire inflation pressure can-
not be set easily
●Normally, the tire inflation pres-
sure setting procedure can be
completed in 2 or 3 minutes.
●If the tire pressure warning light
does not blink 3 times when start-
ing the tire inflation pressure set-
ting procedure, the procedure
may not have started. Perform the
procedure again from the begin-
ning.
●If tire inflation pressure setting
procedure cannot be completed
after performing the above proce-
dure, contact your Toyota dealer.
The tire pressure warning valve
and transmitter is equipped with
a unique ID code. When new
tire pressure warning valves and
transmitters are installed, new
ID codes must be registered in
the tire pressure warning com- puter.

ID codes can be registered by
yourself, but depending on
the driving conditions and
driving environment, registra-
tion may take some time to
complete.
 When using a wheel set
which all of the ID codes have
already been registered, the
wheel set can be changed in
a short amount of time.
Before performing ID code reg-
istration, make sure that no
wheels with tire pressure warn-
ing valve and transmitters
installed are near the vehicle.
4.2-inch display
1 Park the vehicle in a safe
place and turn the engine
switch off, wait for approxi-
mately 20 minutes or more,
and then start the engine.
The ID code registration procedure

Registration may take longer than
normal to complete if the vehicle
speed cannot be maintained at
approximately 25 mph (40 km/h) or
more. If registration cannot be com-
pleted after driving for 1 hour or
more, perform the registration pro-
cedure again from the beginning.

the wheel set installed differs
from that of the previous set,
it will be necessary to per-
form the tire inflation pres-
sure setting procedure of the
tire pressure warning system.
If the specified tire inflation pres-
sure is the same, it will not be nec-
essary to per form the tire inflation
pressure setting procedure.

■Replacing tire pressure warn-
ing valves and transmitters
(vehicles with a tire pressure
warning system)
●Because tire repair or replace-
ment may affect the tire pres-
sure warning valves and
transmitters, make sure to have
tires serviced by your Toyota
dealer or other qualified service
shop. In addition, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.
●Ensure that only genuine Toyota
wheels are used on your vehi-
cle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.
