tialization does not complete after driv-
ing for 1 hour or more, park the vehicle in a safe place for more than 15 min-utes and please drive a vehicle once
again with the engine switch ON. ( →P.285)
■Initialization procedure
●Make sure to carry out initialization
after adjusting the tire inflation pres- sure.Also, make sure the tires are cold
before carrying out initialization or tire inflation pressure adjustment.
●If you have accidentally turned the engine switch off during initialization, it is not necessary to press the reset
switch again as initialization will restart automatically when the engine switch is turned to ON the next time.
●If you accidentally press the reset switch when initialization 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 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. (Usu-ally, the vehicle will need to be driven
for approximately 10 to 30 minutes to complete initialization.) If initialization is not complete after driving approxi-
mately 30 minutes, continue driving for a while.• If the vehicle is driven on an unpaved
road, it may take longer to complete initialization.• If the vehicle is backed up while per-
forming initialization, data collected during initialization will be cleared and it will take longer than normal to com-
plete.
• If the vehicle is driven in heavy traffic or another situation where other vehi-cles are driven close by, it may take
time for the system to recognize the tire pressure warning valve and trans-mitters of your vehicle over those of
other vehicles.
If initialization is not complete after driv-
ing for approximately 1 hour, park the
vehicle in a safe place for more than 15
minutes and then drive the vehicle
again.
●In the following situations, initialization
will not be started or was not com- pleted properly and the system will not operate properly. Perform 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 vehicle 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,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
The tire pressure warning valve

■When initializing the tire pres- sure warning system
Do not initialize the tire pressure
warning system without first adjusting the tire inflation pressure to the speci-fied level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation
pressure is actually normal.
