Hyundai Sonata: 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.
