In this tutorial, we learn how to use different drive modes in the 2010 Prius. The Prius offers a smooth and gentle ride, and new technology lets you tailor the driving experience to your needs. All you have to do is press the button and let the car do the rest. The EV mode lets you drive for longer distances at low speeds using the electric motor only. This is an extremely quiet ride that doesn't produce any emissions. The ECO mode makes the most of fuel economy, even on stop and go city streets. The engine burns less gas and adjusts air conditioning. The PWR mode adjusts drive response by adjusting how you drive through different settings along the time you're driving. You can also drive normally and still save on gas costs!
