OUTLINE
In order to set all SRTs, the self-diagnoses as in the “SRT ITEM” table must have been performed at least once. Each diagnosis may require actual driving for a long period of time under various conditions.
 
 
SRT ITEM
The table below shows required self-diagnostic items to set the SRT to “CMPLT”.
