It's okay to drive with the eco light on, especially when city driving or driving in stop and go traffic as eco mode helps you save fuel.
However because eco mode limits your throttle response you should turn eco mode off when highway driving to get more power.
Eco mode also reduces your air conditioning output to save on fuel as well.
To turn eco mode off you simply press the eco mode button and it will turn the eco mode off and then you simply press the button again to turn eco mode back on.
The eco button is often located near the steering wheel or shifter and pressing it turns the mode on or off and may have a leaf symbol as well and say eco.

Although a flashing eco light, especially when it's paired with a flashing check engine light can indicate a more serious engine problem or emission system problem and could be due to a faulty sensor, low oil level or dirty air filter.
If the eco light is flashing, especially with a flashing check engine light you should have the vehicle scanned with an OBD-II scanner to find the specific code and cause.
