Selecting wheel set
Your vehicle is equipped with a tire
pressure warning system with a func-
tion 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 regis-
tered to the system. If a second
wheel set has not been registered,
"Set 2 (Unregistered)" will be dis-

change to the selected wheel set.
ID codes can be registered by yourself.

wheel sets normally. Cancel regis-
tration before changing between
wheel sets.
