DESCRIPTION Moving the
shift lever to S enables the shift range to be selected. The shift range
can be selected by operating the "+" or "-" shift paddle switch. WIRING DIAGRAM
 CAUTION / NOTICE / HINT
NOTICE: After
turning the power switch off, waiting time may be required before
disconnecting the cable from the negative (-) auxiliary battery
terminal. Therefore, make sure to read the disconnecting the cable from
the negative (-) auxiliary battery terminal notices before proceeding
