radio wave conditions, the display
may be corrected by driving and
changing the radio wave condi-
tions.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system w ill change in
accordance with the conditions
under which it was initialized. For
this reason, the system may give a
warning even if th e tire pressure
does not reach a low enough level,
or if the pressure is higher than the
pressure that was adjusted to when
the system was initialized.

Maintenance and care
multi-information display. Also,
“--” is displayed for inflation
pressure of each tire on the
multi-information display while
the tire pressure warning sys-
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
driving for 1 hour or more, park
the vehicle in a safe place for
approximately 20 minutes and
then drive the vehicle again.
■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
power switch off during initializa-
tion, it is not necessary to restart the initialization again as initializa-
tion will restart automatically when
the power 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 s
pecified 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 pressure of a tire
drops, the tire pressure warning
light will come on.
■When initializat ion of the tire
pressure warning system has
failed
Initialization may take longer to
complete if the vehi cle 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 not 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 ho ur, 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 p erform the ini-
tialization procedure again from
the beginning.
