Driving your vehicle
Active ECO operation
Active ECO helps improve fuel efficiency
by controlling the engine and transaxle.
But fuel-efficiency can be changed by the
driver's driving habits and road condi-
tions.
• When the Active ECO button is
pressed the ECO indicator (green) will
illuminate to show that the Active ECO
is operating.
• When the Active ECO is activated, it
does not turn off even though the
engine is restarted again. To turn off
the system, press the active ECO but-
ton again.
• If Active ECO is turned off, it will return
to the normal mode.
Limitation of Active ECO
operation:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though there is
no change in the ECO indicator.
• When the coolant temperature is low:
The system will be limited until engine
performance becomes normal.
• When driving up a hill:
The system will be limited to gain power
when driving uphill because the engine
torque is restricted.
• When using sports mode:
The system will be limited according to
the shift location.
• When the accelerator pedal is deeply
pressed for a few seconds:
The system will be limited, judging that
the driver wants to speed up.
