Hyundai Azera: 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 depressed for a few seconds: The system will be limited, judging that the driver wants to speed up.
