DIRECT MODE CONTROL OUTLINE [SJ6A-EL]
Features
Direct mode control enables temporary use of manual shifting using the steering shift switch even when the
selector lever is in the D range.
The transmission can be controlled at the driver's discretion by operating the steering shift switch, which
enables effective downshift during deceleration using engine brake force, cornering after deceleration, and
acceleration when passing.
After switching to direct mode, the system returns to automatic shift mode automatically in accordance with
driving conditions.
