Step-by-Step Guide: Using the Eco Assist System Effectively

To harness the full potential of the Eco Assist System in your Acura ILX Hybrid, it's essential to understand how to interpret its feedback and adjust your driving accordingly. Below is a detailed guide on how to do this:

1. Familiarize Yourself with the Eco Assist Display

When you start your ILX Hybrid, look at the dashboard's Eco Assist leaf indicator. This display is your primary source of feedback on how efficiently you are driving. The leaves light up progressively based on your driving habits:

  • More Leaves: Indicates fuel-efficient driving—gentle acceleration, steady speeds, and smooth braking.
  • Fewer Leaves: Suggests aggressive acceleration, rapid deceleration, or excessive idling, all of which reduce efficiency.

Pay close attention to this display as it updates in real time; it’s a useful tool to guide your driving style during each trip.

2. Activate the Econ Mode for Optimal Efficiency

Press the Econ button located on the center console or dashboard. Activating this mode adjusts the vehicle’s throttle response, making acceleration less sensitive and reducing power demand. Additionally, the climate control system modifies its operation to reduce electrical load, such as by adjusting air conditioning compressor activity.

Keep in mind that while Econ mode improves efficiency, it may slightly affect acceleration responsiveness and climate control comfort. Use this mode primarily during city driving or highway cruising where maximum power is less necessary.

3. Practice Smooth Acceleration and Deceleration

The Eco Assist System rewards gentle pressure on the accelerator and gradual braking. Avoid sudden starts and stops, as these consume more fuel and reduce the number of leaves displayed on the Eco Assist indicator.

Try to anticipate traffic flow and maintain a steady speed. When approaching a stoplight or traffic jam, ease off the accelerator early and brake softly. This not only improves fuel efficiency but also maximizes regenerative braking, which helps recharge the hybrid battery.

4. Monitor the Energy Flow Monitor

The ILX Hybrid’s instrument cluster includes an energy flow monitor that visually represents when the vehicle is using gasoline, electric power, or regenerative braking. This feature helps you understand how the hybrid system operates and how your driving impacts energy use.

Use this display to learn when the vehicle switches between power sources. Aim to maximize electric power use and regenerative braking by maintaining efficient driving habits.

5. Limit Use of Accessories That Increase Energy Consumption

While driving, be mindful of accessories such as heated seats, defrosters, and powerful climate control settings, which can increase electrical load and reduce overall efficiency. Econ mode helps manage some of these systems automatically, but manual adjustments can also make a difference.

6. Plan Your Routes and Trips

Efficient driving begins even before you start the engine. Planning routes that avoid heavy traffic, steep hills, and frequent stops can improve the effectiveness of the Eco Assist System. Consider carpool lanes, highways, or roads with fewer traffic lights to minimize stop-and-go driving.

Additional Tips for Maximizing Fuel Efficiency in Your Acura ILX Hybrid
