Drive straight (with occa-
sional left and right turns) at
approximately 25 mph (40
km/h) or more for approxi-
mately 10 to 30 minutes.
When wheel position registration is
complete, a message indicating
that registration has been com-
pleted and the inflation pressure of
each tire will be displayed on the
multi-information display.
Even if it is not possible to drive
continuously at approximately 25
mph (40 km/h) or more, registration
can be completed by driving for a
long time. However, if registration
does not complete after driving for
1 hour or more, park the vehicle in
a safe place and leave it with the
power switch in ON for approxi-
mately 15 minutes or more, and
then perform the driving procedure
again.
■ When performing wheel posi-
tion registration
● Normally, wheel position registra-
tion can be completed within
approximately 30 minutes.
● Wheel position registration is per-
formed while driving at a vehicle
speed of approximately 25 mph
(40 km/h) or more.
■ Wheel position registration pro-
cedure
● If the power switch is turned off
while registering the wheel posi-
tion, the next time the power
switch is turned to ON, the wheel
position registration will resume
and it will not be necessary to
restart the procedure.
● While the position of each wheel is
being determined and the inflation
pressures are not being dis-
played, if the inflation pressure of
a tire drops, the tire pressure
warning light will come on.

■ If the wheel position cannot be
registered easily
● In the following situations, wheel
position registration may take lon-

• Vehicle is driven on unpaved
roads
• If wheel position registration does
not complete after driving for 1
hour or more, park the vehicle in a
safe place for approximately 15
minutes and then drive the vehicle
again.
● If the vehicle is reversed during
wheel position registration, all
data collected until then will be
cleared. Perform driving again.
Setting the tire pressure
In the following situations, it will
be necessary to perform the tire
inflation pressure setting proce-
dure of the tire pressure warning
system.
 When the specified tire infla-
tion pressure has changed,
such as due to carried load,
etc.
 When the tire inflation pres-
sure is changed such as
when the tire size is changed.
If the tire inflation pressure has
been adjusted to the specified
level, perform the tire inflation set-
ting procedure by selecting speci-
fied inflation pressure on the multi-
information display.
When the tire inflation pressure is
to be other than specified, such as
when tires other than the specified
size are used, etc., set the tire infla-
