Eco Mode is generally during driving, ensuring that the most miles can be covered with just a gallon of gas or just a liter of fuel. On the technical side, Eco Mode does inhibit the performance of the engine and transmission, by reducing the response of throttle in an effort to boost fuel economy.

Should I turn ECO mode off?

You should use Eco Mode whenever you want to save fuel, of course! But since it affects your vehicle's performance, you shouldn't use Eco Mode anytime you anticipate you might need the extra performance. This means on highways and other busy roads; you should consider keeping Eco Mode switched off.

What is the purpose of eco mode?
