●Do not move the vehicle backward
during registration. Registration is started again from the beginning and it may take longer than usual.
●When another vehicle is running the side of the vehicle such as in heavy traffic, it
may take longer to detect the vehicle’s tire pressure warning valves and trans-mitters.

may not be registered.

procedure for ID code registration again
after parking the vehicle for 20 minutes.
If the ID codes cannot be registered even
