Registering ID codes
The tire pressure warning valve and
transmitter is equipped with a unique
ID code. When new tire pressure
warning valves and transmitters are
installed, new ID codes must be regis-
tered in the tire pressure warning com-
puter.
ID codes can be registered by your-
self, but depending on the driving
conditions and driving environ-
ment, registration may take some
time to complete.
When using a wheel set which all of
the ID codes have already been reg-
istered, the wheel set can be
changed in a short amount of time.

tion, make sure that no wheels with tire
pressure warning valve and transmit-
ters installed are near the vehicle.
