Well Usman Bhai I've seen the Reviews of many Cars Internationally, Many have this green button to activate the efficiency mode.Its a totally new Function of the e Button that U can say a new advancement & a good initiative for PAKISTAN. Also as we all know that the world is going towards Saving the Fuel for Future so Go Green is kind of a campaign in whole World But still not initiated in Pakistan.
HONDA's e Con
As I've seen along time ago the reviews of HONDA, according to them when you press that green button:
1.The green leaf indicator Shows us how Greeener or efficiently you are driving your car.(Its also in Corolla, But its simply a Light that turns ON till 2-3 RPM)
The real actions things are:
1.Throttle response Softened, as its been controlled electronically to get the good efficiency & reduces throttle opening for a given pedal input
2.Gear in A/T changes at Considerably lower RPMs. More foot motion is required for gear changes, pressing the button again cancels Econ mode.
3.In Cruise control, limits acceleration/throttle opening rates when engaged, which may allow more vehicle speed variations especially on hills
4.Also it effects the AC to be efficient when its on AUTO mode(Climate Control, Don't know we got it in Pak or not)
NOTE: I can't Guarantee all Friends here that we will get all these e CON Functions here in Pak for sure, I've Shared my knowledge what I've saw in other Country's Vehicles. There will be some functions from the list we will get!!
