Active ECO helps improve fuel efficiency by controlling the engine and transaxle. Fuel-efficiency is determined by the driver's driving habits and road conditions.

Active ECO is designed on the assumption of light to mild throttle driving style to control engine and transaxle in order to optimize fuel economy. A person with an aggressive throttle driving style may find the engine performance in Active ECO on mode to be unsatisfactory, and thus may not realize any fuel economy gain.
