Maintenance and care
■Initializing the tire pressure
warning system
Initialize the syst em with the tire
inflation pressure adjusted to the
specified level.
■Initialization procedure
●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 pressure adjustment.
●If you have accidentally turned the
engine switch off during initializa-
tion, it is not necessary to restart
the initialization ag ain as initializa-
tion will restart aut omatically when
the engine switch has been turned
to ON for the next time.
●If you accidentally restart the ini-
tialization when ini tialization is not
necessary, adjust the tire inflation
pressure to the specified level
when the tires are cold, and con-
duct initialization again.
●While the position of each tire is
being determined and the inflation
pressures are not being displayed
on the multi-information display, if
the inflation pres sure of a tire
drops, the tire pressure warning
light will come on.
■When initialization of the tire
pressure warning system has
failed
Initialization may take longer to
complete if the vehicle is driven on
an unpaved road. When performing
initialization, drive on a paved road if
possible. Depending on the driving
environment and condition of the
tires, initialization will be completed
in approximately 10 to 30 minutes. If
initialization is n ot complete after
driving approximately 10 to 30 min-
utes, continue driving for a while.
If the inflation pressure of each tire
is not displayed after driving for
approximately 1 hour, perform the following procedure.
●Park the vehicle in a safe place for
approximately 20 minutes. Then
drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes.
However, in the following situations,
the tire inflation pr essure will not be
recorded and the system will not
operate properly. Perform initializa-
tion 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 operating the tire pressure
warning reset switch, the tire pres-
sure warning light does not blink 3
times.
●After performing initialization, the
tire pressure warn ing light blinks
for 1 minute then stays on while
driving.
If the inflation pressure of each tire
is still not displayed, have the vehi-
cle inspected by your Toyota dealer.
Every tire pressure warning
valve and transmitter has a
unique ID code. When replacing
a tire pressure warning valve
WARNING
■When initializing the tire pres-
sure warning system
Do not initializing tire inflation
pressure without f irst adjusting
the tire inflation pressure to the
specified 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.
