tem determines the position.
Drive the vehicle at approxi-
mately 25 mph (40 km/h) or
more for approximately 10 to 30
minutes until the inflation pres-
sure of each tire is displayed on
the multi-information display.
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 completed by driving for a
long time. However, if initializa-
tion does not complete after

■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 ou t 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 again 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 initialization 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-inform
ation 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
Initialization may take longer to
complete if the ve hicle 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 no t 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
