inflation pressure of each tire is displayed
on the multi-information display.
Registration may take longer than normal
to complete if the vehicle speed cannot be
maintained at approximately 40 km/h (25
mph) or more. If registration cannot be
completed after driving for 1 hour or more,
perform the registration procedure again
from the beginning. (P.497)
After registering the ID codes, make sure
to initialize the tire pressure warning sys-
tem. (P.494)
When registering ID codes
■
Before performing ID code registration,
●
make sure that no wheels with tire pres-
sure 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 initialized before
registering the ID codes, the initialized
values will be invalid.
As the tires will be warm when registra-
●
tion is completed, make sure to allow the
tires to cool before performing initializa-
tion.
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 regis-
tration 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 warning light will blink
for approximately 1 minute when the
power switch is turned to ON mode and
then illuminate. The tire pressure warning
system will be operational when the tire
pressure warning light turns off.
If the warning light does not turn off even
●
after several minutes have elapsed, ID
code registration may not have been can-
celled correctly. To cancel registration,
perform the ID code registration start

6-3. Do-it-yourself maintenance
procedure again and then turn the power
switch off before driving.
If ID codes are not registered properly
■
In the following situations, ID code regis-
●
tration may take longer than usual to be
completed or may not be possible. (Usu-
ally, the vehicle will need to be driven for
approximately 10 to 30 minutes to com-
plete ID code registration.)
If ID code registration is not complete
after driving for approximately 30 min-
utes, continue driving for a while.
• If the vehicle is driven on an unpaved
road, it may take longer than normal to
complete registration.
• If the vehicle is backed up while perform-
ing registration, data collected during
registration will be cleared, and it will take
longer than normal to complete.
• If the vehicle is driven in heavy traffic or
another situation where other vehicles
are driven close by, it may take time for
the system to recognize the tire pressure
warning valve and transmitters of your
vehicle over those of other vehicles.
• If a wheel with a tire pressure warning
valve and transmitter installed is inside or
near the vehicle, registration of the ID
codes for the installed wheels may not be
possible.
If ID registration is not complete after driv-
ing for approximately 1 hour, park the vehi-
cle in a safe place for approximately 20
minutes and then perform the ID code reg-
istration procedure again.
In the following situations, ID code regis-
●
tration will not be started or was not com-
pleted properly and the system will not
operate properly. Perform the ID code
registration procedure again.
• If, when attempting to start ID code regis-
tration, the tire pressure warning light
does not blink slowly 3 times.
• If, when the vehicle has been driven for
about 10 minutes after performing ID
code registration, the tire pressure warn-
ing light blinks for approximately 1 minute
and then illuminates.
If ID code registration cannot be com-
●
pleted after performing the above proce-
