Hi buddies, I have alto eco 2014. i am confused with a thing that happens after trip completion. when i switch off the engine the odometer shows summary of the trip i.e time, ml, eco etc, my problem is that it shows "eco 100" msg, while few days before as i purchased the car that time it was showing "eco 0". what is mean by "eco 100" and "eco 0" ?? can anybody explain???
