In short it reduces available horsepower, and it also limits the AC unit so that it doesn't run as frequently, thereby reducing engine demand.Eco-mode Function
The engine and CVT are constantly controlled in a coordinated way by a computer that normally switches automatically between high-performance and fuel-efficiency modes depending on driving conditions.
The Eco-mode Function incorporates a coordinated control program that makes maximum use of fuel efficiency mode to further improve the vehicle's efficiency. Drivers can easily switch to Eco-mode using either the car navigation system screen or the Eco-mode switch.
Cars driving in Eco-mode respond more gradually to accelerator input. However, in emergency avoidance and other situations when rapid acceleration is necessary, the computer immediately switches the system to enable quick acceleration.
