Active ECO System

1.

Active ECO System While the general eco system encourages the driver to drive efficiently by displaying ECO lights on the dashboard, the active ECO system controls the transmission forcibly to achieve fuel efficiency. The driver can activate the active ECO button on the steering wheel to engage this mode. If the active ECO is selected, then the engine and transmission are controlled with priority placed on fuel efficiency. It achieves even greater fuel economy than the conventional system. The active ECO system may not engage under certain conditions. (e.g., when driving up an incline or before the engine is warmed up). If active ECO is not selected, then the general ECO System can be selected and engaged.

Active ECO Features A. Engine control - Minimizes fuel consumption caused by unnecessary acceleration: Limits engine torque during acceleration (disengages limit control when starting to move or accelerating suddenly to ensure trouble-free performance). B. Transmission control - Lowers the up shift vehicle speed: Lowers engine RPM when driving. - Prevents down shift if possible: Prevents driving under high engine RPM. - Expands the direct connection area of the torque converter. Inform the driver that the following conditions are not malfunctions. 1. The active ECO system provides improved fuel efficiency through direct control of the engine / transmission, but the actual fuel saved may be less than you expect, depending on the driving conditions and the driver's driving habits. 2. The active ECO limits acceleration on flat ground to conserve fuel, but this feature is disengaged when driving up an inclined road. 3. When a driver activates the active ECO System, the mode is maintained until the driver deactivates the system. 4. The conventional eco driving notices are not activated when active ECO is on. However, a green lamp on the dashboard is permanently on. (The constant on state of the green lamp signifies that the active ECO system is currently engaged.)

Conditions That Prevent Active ECO System Engagement (1) Active ECO is not active when the coolant temperature falls below the preset level. (2) Active ECO is not active if the APS opening is maintained for longer than the preset limit. (3) Active ECO is not active if the check engine lamp is blinking. (4) Active ECO is not active if a CAN error message occurs. (5) Active ECO is not active if a deactivate signal is triggered by the TCU. (6) Active ECO is not active if VDC is engaged. (7) Active ECO is not active if pattern is switched to other than the normal or active ECO transmission pattern.
