ing for 1 hour or more, park the vehicle
in a safe place for approximately 20
minutes and then drive the vehicle
again.
■ When initializing
● Initialization is performed while driving
at a vehicle speed of approximately
40 km/h (25 mph) or more.
● 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.
● The tire pressure warning system can
be initialized by yourself, but depend-
ing on the driving conditions and driv-
ing environment, initialization may
take some time to complete.
■ The initialization operation
● If you have accidentally turned the
power switch to OFF during initializa-
tion, it is not necessary to restart the
initialization again as initialization will
restart automatically when the power
switch has been turned to ON for the
next time.
● If you accidentally perform initializa-
tion 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. Nor-
mally, initialization completes within
approximately 30 minutes.
• Vehicle is not driven 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 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 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 reversed 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. 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, con-
tact any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
