How to Turn Off Eco Mode on a Mitsubishi Mirage: Complete Guide for Every Model Year

Eco Mode is a signature feature in the Mitsubishi Mirage, designed to boost fuel efficiency and minimize emissions. However, there are times when drivers crave more responsiveness or power—especially during highway driving or steep climbs. This comprehensive guide explains how to turn off Eco Mode on your Mitsubishi Mirage, what happens when you do, and how to optimize performance and fuel economy.

🚗 Understanding Eco Mode in the Mitsubishi Mirage

Eco Mode automatically adjusts throttle response, engine output, and even transmission timing to reduce fuel consumption. When active, it prioritizes smooth acceleration, conservative power delivery, and efficient fuel use—perfect for city driving or steady commutes.

However, the trade-off is reduced throttle sensitivity and slower response times. That’s why many Mirage owners choose to disable it temporarily for better control and acceleration.

⚙️ Why You Might Want to Turn Off Eco Mode

There are specific driving conditions where turning off Eco Mode is beneficial:

• Highway Merging or Overtaking: You’ll need full power to accelerate quickly.
• Mountain or Hill Driving: Steep inclines require stronger torque and throttle response.
• Towing or Heavy Loads: Eco Mode can limit engine power, making it harder to haul weight.
• Cold Weather: Disabling Eco Mode allows faster warm-up and more stable idle.
• Personal Preference: Some drivers simply prefer a more engaging driving experience.

🧭 Step-by-Step: How to Turn Off Eco Mode on a Mitsubishi Mirage

The process varies slightly depending on your Mirage’s model year and trim, but the methods are generally straightforward.

1. Locate the Eco Button

Most Mitsubishi Mirage models have a physical ECO button—look for it on:

• The center console near the gear shifter.
• The dashboard near the steering wheel.
• On some trims, it may appear on the touchscreen infotainment system under vehicle settings.

2. Press the Eco Button Once

• Press the ECO button once to deactivate the mode.
• The Eco indicator light on the dashboard should turn off, confirming deactivation.

If the light remains on, check your owner’s manual—some models require a longer press or a vehicle restart.

3. Use the Touchscreen Settings (For Newer Models)

On Mirage models with a touchscreen display:

• Go to Menu → Vehicle Settings → Driving Modes → Eco Mode.
• Toggle the switch off.
• The dashboard indicator will disappear once Eco Mode is disabled.

4. Automatic Deactivation

In some Mirage variants, Eco Mode automatically turns off when:

• You accelerate aggressively.
• You reach highway speeds.
• You switch to manual gear mode (for CVT trims).

🧩 Troubleshooting: Eco Mode Won’t Turn Off

If your Mirage’s Eco Mode remains active after pressing the button, it could indicate a minor glitch or system issue. Here’s what to check:

1. Electrical or Button Contact Problems

• Dust or debris may block the button’s sensor—clean it gently.
• If pressing the button has no effect, try turning the ignition off and on again.

2. Software Glitch

• Disconnect the car battery for 5–10 minutes to reset the system.
• Reconnect and test again—this often clears minor electronic faults.

3. Automatic Re-Engagement

Some Mirage models automatically re-enable Eco Mode under specific conditions, such as:

• Low battery voltage
• Cold starts
• Extended idle periods

If Eco Mode reactivates frequently or erratically, have a technician check your engine control module (ECM) at a Mitsubishi service center.

⚡ Driving Without Eco Mode: What to Expect

Turning off Eco Mode instantly alters how your Mirage behaves:

Benefits

• Faster acceleration and throttle response
• Better hill-climbing and highway merging
• Improved performance during overtaking

Drawbacks

• Slightly lower fuel economy
• Higher emissions output
• Louder engine noise during acceleration

🛠️ Tips for Maximizing Fuel Efficiency Without Eco Mode

Even when Eco Mode is off, there are plenty of ways to maintain great fuel economy:

1. Smooth Acceleration

Avoid sudden throttle inputs—gradual acceleration saves gas.

2. Maintain Proper Tire Pressure

Underinflated tires increase rolling resistance, forcing your engine to burn more fuel.

3. Reduce Weight

Remove unnecessary cargo and accessories to improve efficiency.

4. Regular Maintenance

Change air filters, use the correct oil grade, and keep your engine tuned.

Yes, though you’ll consume slightly more fuel. Many drivers keep it off for performance-based driving.

🧠 Final Recommendations for Managing Eco Mode

To get the best out of your Mitsubishi Mirage, understand when to prioritize fuel savings and when to maximize power:

• Use Eco Mode: During city commutes, stop-and-go traffic, or long trips where efficiency matters most.
• Disable Eco Mode: On highways, steep roads, or whenever immediate power is essential.

Balance is key—adjust the setting to suit your journey, not just your fuel budget.
