Canceling ID code registration
To cancel ID code registration after it has been started, select [New tyre registra-
tion] again on the center display.
If ID code registration has been canceled, the tire pressure warning light will turn off.
If the warning light does not turn off, ID code registration may not have been cancelled
correctly. To cancel registration, select [New tyre registration] again on the center display.
Selecting wheel set
Your vehicle is equipped with a tire pressure warning system with a function to
register two sets of ID codes. This allows for registration of a second wheel set, for
example a winter set.
● The wheel set can be changed only if a second wheel set has been registered to
the system. If a second wheel set has not been registered, "Set 2(Unregistered)"
will be displayed and it will not be possible to change to the selected wheel set.
ID codes can be registered by yourself.
