cally when the engine switch has
been turned to ON for the next
time.
• Vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved
roads
●If you accidentally perform the ini-
tialization when initialization is not
necessary, adjust the tire inflation
pressure to the specified level
when the tires are cold, and con-
duct initialization again.
• Vehicle is driven near other vehi-
cles and system cannot recog-
nize tire pressure warning valve
and transmitters of your vehicle
over those of other vehicles.
●Vehicles with tire inflation pres-
sure display function only: 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
inflation pressure of a tire drops,
the tire pressure warning light will
come on.
If initialization does not complete
after driving for 1 hour or more, park
the vehicle in a safe place for
approximately 20 minutes and then
drive the vehicle again.
●If the vehicle is reversed during
initialization, the data up to that
point is reset, so perform the ini-
tialization procedure again from
the beginning.
■When initialization of the tire
pressure warning system has
failed (vehicles without tire
inflation pressure display func-
tion)
●In the following situations, initial-
ization will not be started or was
not completed properly and the
system will not operate properly.
Perform the initialization proce-
dure again.
• If, when attempting to start initial-
ization, 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.
Initialization can be completed in a
few minutes. However, in the follow-
ing cases, the settings have not
been recorded and the system will
not operate properly. If repeated
attempts to record tire inflation pres-
sure settings are unsuccessful,
have the vehicle inspected by your
Toyota dealer.
●When operating the tire pressure
warning reset switch, the tire pres-
sure warning light does not blink 3
times.
If the inflation pressure of each tire
is still not displayed, have the vehi-
cle inspected by your Toyota dealer.
●After driving for a certain period of
time since the initialization has
been completed, the warning light
comes on after blinking for 1 min-
ute.
■If the tire pressure warning sys-
tem is not initialized properly
(vehicles with tire inflation pres-
sure display function)
In the following situations, initializa-
tion may take longer than usual to
be completed or may not be possi-
ble. Normally, initialization com-
pletes within approximately 30
minutes.
