What does the blue light on a Honda Dash mean?

The blue light on a Honda dashboard typically indicates that the vehicle's Eco Assist system is active. The Eco Assist system is a feature designed to help drivers improve their fuel efficiency by providing real-time feedback on driving habits and suggesting ways to optimize fuel consumption.


Understanding the Honda Eco Assist System


The Eco Assist system in Honda vehicles is a technology that aims to help drivers achieve better fuel economy. It does this by monitoring various factors, such as acceleration, braking, and engine performance, and providing visual feedback to the driver through the dashboard display.



  • When the blue Eco Assist light is illuminated, it indicates that the driver is operating the vehicle in an efficient manner, which can help maximize fuel economy.

  • The blue light will flash when the driver is accelerating or braking in a way that is less efficient, prompting them to adjust their driving style.

  • The Eco Assist system also provides a real-time "Eco Guide" that displays a bar graph showing the current fuel efficiency of the vehicle, allowing the driver to monitor their performance and make adjustments as needed.


By using the Eco Assist system, Honda drivers can learn to adopt more fuel-efficient driving habits, which can lead to significant savings in fuel costs over time.


Other Dashboard Lights on Honda Vehicles


In addition to the blue Eco Assist light, Honda dashboards may display a variety of other indicator lights, each with its own meaning and purpose. Some common dashboard lights include:



  • Check Engine Light: Indicates a problem with the vehicle's engine or emissions system that requires attention.

  • Maintenance Required Light: Alerts the driver that the vehicle is due for scheduled maintenance, such as an oil change or tire rotation.

  • Brake System Light: Indicates a problem with the vehicle's braking system that requires immediate attention.

  • Tire Pressure Monitoring System (TPMS) Light: Alerts the driver when one or more tires have low air pressure.


It's important for Honda owners to familiarize themselves with the meaning of these dashboard lights and to address any issues promptly to ensure the safe and efficient operation of their vehicle.
