Drive at approximately 25
mph (40 km/h) or more for
approximately 10 to 30 min-
utes.
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, initializat ion can be com-
pleted by driving for a long time.
However, if initia lization does not
complete after driving for 1 hour or
more, park the vehicle in a safe
place for approximately 20 minutes
and then drive th e vehicle again.
■When initializing
●Initialization is performed while
driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●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 tir e inflation pres-
sure adjustment.
●The tire pressure warning system
can be initialized by yourself, but
depending on the driving condi-
tions and driving environment, ini-
tialization may take some time to complete.
■The initialization operation
●If you have accidentally turned the
power switch off during initializa-
tion, it is not necessary to manu-
ally restart the initialization again,
as initialization will restart auto-
matically the next time the power
switch is turned to ON.
●If you accidentally perform initial-
ization when initia
lization 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.
■If the tire pressure warning sys-
tem is not initia lized properly
●In the following situations, initial-
ization may take longer than usual
to be completed or may not be
possible. Normally, initialization
completes within approximately
30 minutes.
• Vehicle is not dr iven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehi-
cles and system cannot recog-
nize tire pressure warning valve
and transmitters o f your vehicle
over those of other vehicles
If initialization 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.
●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.
●In the following situations, initial-

7Drive at 25 mph (40 km/h) or
more for approximately 10 to
30 minutes.
Registration is complete when the
tire pressure warning light turns off
and the inflation pressure of each
tire is displayed on the multi-infor-
mation display.
Even if the vehicle is not driven at
approximately 25 mph (40 km/h) or
more, registration can be com-
pleted by driving for a long time.
However, if regist ration does not
complete after driving for 1 hour or
more, perform the procedure again
from the beginning.

warning system. ( P.407)
■When registering ID codes
●ID code registration is performed
while driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Before performin g ID code regis-
tration, make sure that no wheels
with tire pressur e warning valve
and transmitters installed are near
the vehicle.
●Make sure to initialize the tire
pressure warning system after
registering the ID codes. If the
system is initializ ed before regis-
tering the ID codes, the initialized
values will be invalid.
●ID codes can be registered by
yourself, but depending on the
driving conditions and driving
environment, registration may
take some time to complete.
■Canceling ID code registration
●To cancel ID code registration
after it has been started, turn the
power switch off before driving the
vehicle.
If the vehicle is driven after ID
code registration is started, to
cancel registration, perform the ID code registration start procedure
again and turn the power switch
off before driving.
●If ID code registration has been
canceled, the tire pressure warn-
ing light will blin
k for approxi-
mately 1 minute when the power
switch is turned to ON and then
illuminate. The tire pressure warn-
ing system will be operational
when the tire pressure warning
light turns off.
●If the warning lig ht does not turn
off even after several minutes
have elapsed, ID code registration
may not have been canceled cor-
rectly. To cancel registration, per-
form the ID code registration start
procedure again and then turn the
power switch off before driving.
■If ID codes are not registered
properly
●In the following situations, ID code
registration may take longer than
usual to be completed or may not
be possible. Normally, registration
completes within approximately
30 minutes.
• Vehicle is not parked for approxi- mately 20 minutes or more before
driving
• Vehicle is not dr iven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved
roads
• Vehicle is driven near other vehi-
cles and system cannot recog-
nize tire pressure warning valves
and transmitters o f your vehicle
over those of other vehicles
• Wheel with tire p ressure warning
valve and transmitter installed is
inside or near the vehicle
If registration does not complete
after driving for 1 hour or more, per-
