Active ECO System

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
-
|
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).
|
-
|
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.)
