more for approximately 10 to
30 minutes.
When initialization is complete, the
inflation pressure of each tire will be
displayed on the multi-information
display.
Even if the vehicle is not driven at
approximately 25 mph (40 km/h) or
more, initialization can be com-
pleted by driving for a long time.
However, 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.
■ When initializing
● Vehicles with tire inflation pres-
sure display function only: Initial-
ization is performed while driving
at a vehicle speed of approxi-
mately 25 mph (40 km/h) or more.
● Make sure to carry out initializa-
tion after adjusting the tire inflation
pressure. Also, make sure the
tires are cold before carrying out
initialization or tire inflation pres-
sure adjustment.
● Vehicles with tire inflation pres-
sure display function only: The tire
pressure warning system can be
initialized by yourself, but depend-
ing on the driving conditions and
driving environment, initialization
may take some time to complete.
■ The initialization operation
● If you have accidentally turned the
engine switch to OFF during ini-
tialization, it is not necessary to
restart the initialization again as
initialization will restart automati-
cally when the engine switch has
been turned to ON for the next
time.
● 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.
● 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.
■ When initialization of the tire
pressure warning system has
failed (vehicles without tire
inflation pressure display func-
tion)
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.
● 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.
• Vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved
roads
• Vehicle is driven near other vehi-
cles and system cannot recog-
nize tire pressure warning valve
and transmitters of your vehicle
