25 mph (40 km/h) or more for
approximately 10 to 30 minutes.
Initialization is complete when the position
of each tire is determined and the inflation
pressure of each tire is displayed on the
multi-information display.
Initialization may take longer than approxi-
mately 1 hour in certain situations, such as
when the vehicle is stopped for a long time

If the power switch is turned off during
initialization, it is not necessary to restart
the initialization procedure from the
beginning as it will begin automatically
when the power switch is turned back to
ON mode.
If initialization has accidentally been
started when it is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold and then
perform the initialization procedure
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
pressure of a tire drops, the tire pressure
warning light will come on.
