■If the tire pressure warning system is not initialized properly
●In the following situations, init ialization may take longer than usual to be
completed or may not be possible. (Usually, the vehicle will ne ed to be
driven for approximately 10 to 30 minutes to complete initializ ation.)
If initialization is not complete after driving approximately 3 0 minutes,
continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longe r to com-
plete initialization.
• If the vehicle is backed up while performing initialization, d ata col-
lected during initialization will be cleared and it will take l onger than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other
vehicles are driven close by, i t may take time for the system to recog-
nize the tire pressure warning valve and transmitters of your v ehicle
over those of other vehicles.
If initialization is not complete after driving for approximate ly 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
drive the vehicle again.
●In the following situ ations, initialization will not be started or was not
completed properly and the system will not operate properly. Pe rform
the initialization procedure 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 per-
forming initializatio n, the tire pressure warning light blinks for approxi-
mately 1 minute and then illuminates.
●If initialization cannot be completed after performing the abov e proce-
dure, contact your Toyota dealer.

Maintenance and care
■When registering ID codes
●Before performing ID code registration, make sure that no wheels with
tire pressure warning valve and transmitters installed are near the vehi-
cle.
●Make sure to initialize the tire pressure warning system after registering
the ID codes. If the system is initialized before registering t he ID codes,
the initialized values will be invalid.
●As the tires will be war m when registration is completed, make sure to
allow the tires to cool befo re performing initialization.
■Canceling ID code registration
●To cancel ID code registration after it has been started, turn the engine
switch off before driving the vehicle.
If the vehicle is driven after ID code registration is started, to cancel reg-
istration, perform the ID code r egistration start procedure aga in and turn
the engine switch of f before driving.
●If ID code registration has been canceled, the tire pressure wa rning light
will blink for approximately 1 mi nute when the engine switch is turned to
IGNITION ON mode and then illumina te. The tire pressure warning sys-
tem will be operational when the tire pressure warning light tu rns off.
●If the warning light does not turn off even after several minut es have
elapsed, ID code registration may not have been cancelled corre ctly. To
cancel registration, perform the ID code registration start procedure
again and then turn the engine switch off before driving.

■If ID codes are not registered properly
●In the following situations, ID code registration may take longer than
usual to be completed or may not be possible. (Usually, the veh icle will
need to be driven for approximately 10 to 30 minutes to complet e ID
code registration.)
If ID code registration is not complete after driving for appro ximately 30
minutes, continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longe r than
normal to complete registration.
• If the vehicle is backed up while performing registration, dat a col-
lected during registration will be cleared, and it will take longer than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other
vehicles are driven close by, i t may take time for the system to recog-
nize the tire pressure warning valve and transmitters of your v ehicle
over those of other vehicles.
• If a wheel with a tire pressure warning valve and transmitter installed
is inside or near the vehicle, registration of the ID codes for the
installed wheels may not be possible.
If ID registration is not complete after driving for approximately 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
perform the ID code regi stration procedure again.
●In the following situations, ID c ode registration will not be started or was
not completed properly and the system will not operate properly. Per-
form the ID code registr ation procedure again.
• If, when attempting to start ID code registration, the tire pr essure
warning light does not blink slowly 3 times.
• If, when the vehicle has been driven for about 20 minutes afte r per-
forming ID code registration, the tire pressure warning light b links for
approximately 1 minute and then illuminates.
●If ID code registration cannot be completed after performing th e above
procedure, contact your Toyota dealer.
