K313 CVT  CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM  Transmission Control Switch Circuit  


DESCRIPTION

After moving the shift lever to M, it is possible to change the shift range between M1 and M10 using the shift lever. Moving the shift lever to "+" once raises the shift range by one, and moving the shift lever to "-" lowers the shift range by one.
