5 Reasons Why the Eco Light is Not Working

Many, myself included, love having an Eco light on their vehicle. With gas prices soaring right now, it is crucial for us to get the most out of every single fill up at the gas station. But when your Eco light is not working, it is frustrating to anyone that relies on this. 

What is the Eco Light on a Vehicle?

The Eco light on a vehicle is a piece of technology that allows you to get some good fuel economy.

Some drivers believe fully in the eco indicator light, while others say if you just watch how you are driving, you can do the same thing. But with Eco mode, you can drive how you wish and you will still be saving fuel. 

How Does Eco Mode Work?

Eco Mode helps to regulate climate control in a vehicle. Power output and seat heating are also controlled by this. 

To provide you with better fuel economy, the transmission and engine performance are restricted. Should you press as hard as you can on the gas pedal, you will speed up how the car manufacturer intended you to. 

At this time, you will receive maximum fuel economy without adverse side effects. Fuel, air, and other adjustments are provided to help with this. You will not notice a huge change, but may notice a slight decrease in power. 

How Does Eco Mode Work?

You can view the Eco Light on your multi information display. If you are not able to see this, press the Display (or DISP) button on the steering wheel continuously until you can see it.

The better your fuel economy is at that time is when the indicator bar is the closest to the left.

When you use a slight touch on the accelerator, the bar will remain in the eco range and the green eco-indicator will show up on the screen.

When you press hard on the accelerator, the indicator will be removed and the bar will stretch beyond the Eco zone and begin flashing. That means it’s most likely that you’re utilizing more gas than you should be.
