Combustion control mode | Idle speed control | Stops feedback control of idle speed and controls with specified speed. | ||
Recovery speed control at decelerating | Stops recovery speed control by the fuel cut at decelerating and controls with specified speed. | |||
Idle neutral control | Stops idle neutral control. |
note | When depressing accelerator pedal three-fourths (3/4) or more, the control system does not start the engine. Do not depress accelerator pedal too much. |
