K120 / K120F / K121 / K121F CVT K121 / K121F 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.
