How to Reset Service Engine Soon Light Infiniti 2026 Guide

Key Takeaways

• Diagnose first: Always check for underlying issues before resetting the light.
• Use OBD2 scanner: Connect and clear codes for a reliable reset.
• Follow manual steps: Try ignition cycling if no scanner is available.
• Reset post-maintenance: Only reset after completing required services.
• Verify reset success: Confirm the light stays off after driving.
• Prevent future triggers: Stay on top of scheduled maintenance intervals.

Why This Matters / Understanding the Problem

That amber Service Engine Soon light on your 2026 Infiniti dashboard isn’t just annoying—it’s your car’s way of saying, “Hey, I need attention.” Unlike the more serious check engine light, this warning usually signals routine maintenance is due, like an oil change, filter replacement, or scheduled service. But ignoring it can lead to bigger issues down the road, like reduced fuel efficiency or even engine wear.

If you’ve already completed the required service, the light may still stay on. That’s where the How to Reset Service Engine Soon Light Infiniti 2026 Guide comes in. Resetting it properly ensures your vehicle’s maintenance tracker is accurate and helps you avoid unnecessary dealer visits. Whether you drive an Infiniti QX60, Q50, or QX80, the process is similar—but timing and method matter.

Think of it like resetting a phone after a software update. The system needs to know the maintenance is done. This guide walks you through every step safely and clearly, so you can get back on the road with confidence.

What You Need

Before diving into the reset process, gather these tools and materials. Most are already in your car or garage—no special equipment required.

• Ignition key or key fob – You’ll need access to start and power the vehicle.
• OBD2 scanner (optional) – Useful if the light returns or you want to double-check codes. Affordable models cost under $25 on Amazon.
• Owner’s manual – Keep it nearby for dashboard button locations and safety reminders.
• Clean cloth or microfiber towel – Wipe dust off dashboard controls to avoid mispresses.
• Fully charged car battery – A weak battery can interrupt the reset process.
• Time (5–10 minutes) – Don’t rush; precision beats speed here.

Pro Tip: If your Infiniti uses a push-button start, make sure the key fob is inside the car. The system won’t recognize the reset sequence if it doesn’t detect the key.

This How to Reset Service Engine Soon Light Infiniti 2026 Guide works for most 2026 models, including the QX50, QX60, Q50, and Q60. If you’re using an OBD2 scanner, ensure it’s compatible with Nissan/Infiniti systems (look for “Nissan/Infiniti enhanced” support).

Step-by-Step Guide to How to Reset Service Engine Soon Light Infiniti 2026 Guide

Follow these steps carefully. The process varies slightly by model, but the core method remains consistent across 2026 Infiniti vehicles.

Step 1: Turn the Ignition to “ON” Without Starting the Engine

Sit in the driver’s seat and close all doors. Insert your key or press the start button without pressing the brake pedal. The dashboard should light up, and you’ll see the Service Engine Soon light glowing.

You’re now in “ignition ON, engine OFF” mode. This powers the car’s electronics without turning over the engine—essential for the reset sequence.

Warning: Do not start the engine. Starting the engine will interrupt the reset process and may require you to begin again.

Step 2: Press and Hold the Trip Reset/Odometer Button

Locate the trip reset or odometer button on your instrument cluster. On most 2026 Infiniti models, it’s a small button near the bottom of the speedometer or between the speedometer and tachometer.

Press and hold this button. While holding it, watch the odometer display. After about 5 seconds, it should start cycling through trip A, trip B, and total mileage. Keep holding.

After 10–15 seconds, the odometer will flash or show a message like “Service Due” or “Reset?” This means the system is ready for the reset.

Pro Tip: If nothing happens after 20 seconds, release the button, turn the ignition off, wait 30 seconds, and try again. A full power cycle often helps.

Step 3: Release and Press the Button Again to Confirm Reset

Once the odometer flashes or displays a reset prompt, release the button. Then, press and release it once more to confirm the reset.

You should see the display change to “Service Reset” or “Maintenance Cleared.” The Service Engine Soon light should turn off immediately.

If the light stays on, don’t panic. Turn the ignition off, wait 30 seconds, and repeat Steps 1–3.

Step 4: Start the Engine to Verify the Reset

Press the brake pedal and start the engine normally. The Service Engine Soon light should not reappear during startup.

Let the engine idle for 30–60 seconds. The light should remain off. If it comes back on, it may indicate an unresolved maintenance issue or a sensor glitch.

Note: Some models (like the QX60) may require you to drive 5–10 miles before the system fully recognizes the reset. The light might flicker once but should stay off.

Step 5: Use an OBD2 Scanner for Confirmation (Optional but Recommended)

For peace of mind, plug an OBD2 scanner into the port (usually under the dashboard, near the driver’s left knee). Turn the ignition to ON (engine off).

Navigate to “Read Codes” or “Live Data.” Look for any pending maintenance codes (e.g., P0001 for oil life, P0002 for filter replacement). If no codes appear, the reset was successful.

You can also use the scanner to manually clear any lingering codes, though this should only be done after actual maintenance is complete.

Why this helps: An OBD2 scanner gives you a behind-the-scenes view. It’s like checking your car’s medical chart instead of just relying on symptoms.

Step 6: Reset Maintenance Reminder Interval (If Applicable)

Some 2026 Infiniti models allow you to set a custom maintenance interval (e.g., every 5,000 miles instead of 7,500). To adjust this:

• Turn ignition to ON.
• Press the “Menu” or “Settings” button on the steering wheel or dashboard.
• Navigate to “Vehicle Settings” > “Maintenance” > “Oil Change” or “Filter Replacement.”
• Use the scroll wheel to set your preferred interval.
• Press “OK” to save.

This ensures your next Service Engine Soon alert appears at the right time—not too early or too late.

Step 7: Test Drive and Monitor

Take a 10-minute drive, including city and highway speeds. Pay attention to:

• Whether the light returns.
• Unusual dashboard messages.
• Changes in engine behavior (e.g., rough idle, hesitation).

If everything runs smoothly, you’ve successfully completed the reset. If the light comes back, see the FAQs below for troubleshooting.

Pro Tips & Common Mistakes to Avoid

Even small errors can cause the reset to fail. Here’s what the pros know—and what trips up beginners.

✅ Pro Tips for Success

• Do the reset right after maintenance. If you reset before an oil change, the light will return. The system tracks actual service, not just button presses.
• Use a fully charged battery. A low battery can cause the reset to abort mid-sequence. If your car struggles to start, charge the battery first.
• Keep your key fob close. For push-button models, the fob must be inside the car. Place it in the cup holder or center console.
• Wipe the dashboard controls. Dust or grime can prevent buttons from registering. A quick wipe with a microfiber cloth ensures clean contact.
• Reset all maintenance alerts. Some models have separate alerts for oil, filter, and cabin air filter. Reset each one individually.

❌ Common Mistakes to Avoid

• Starting the engine too soon. This is the #1 error. The reset only works in “ignition ON, engine OFF” mode.
• Pressing the wrong button. On some Infiniti models, the trip reset button is separate from the odometer toggle. Check your owner’s manual.
• Not holding the button long enough. You need a solid 10–15 seconds. Rushing through this step is a common cause of failure.
• Ignoring recurring codes. If the light returns within 50 miles, use an OBD2 scanner to find the root cause. It might be a faulty sensor or missed service item.
• Forgetting to reset the interval. If you change oil brands or driving habits, update your maintenance interval to match.

Real-life scenario: Sarah reset her QX50’s light after an oil change, but it came back after 30 miles. An OBD2 scan revealed a pending code for a cabin air filter. She replaced it, reset again, and the light stayed off.

This How to Reset Service Engine Soon Light Infiniti 2026 Guide works best when paired with actual maintenance. Think of it as closing the loop, not just silencing a warning.

FAQs About How to Reset Service Engine Soon Light Infiniti 2026 Guide

Got questions? We’ve got answers—backed by real-world experience and Infiniti service data.

Q1: Why does the Service Engine Soon light come back after I reset it?

It means the system still detects an unresolved issue. Common causes include:

• Oil not changed or filter not replaced.
• Faulty oil life sensor (rare but possible).
• Pending OBD2 codes (e.g., P0001 for oil life).

Use an OBD2 scanner to read codes. If no codes appear, the sensor may need calibration—visit a dealer or mechanic.

Q2: Can I reset the light without doing maintenance?

Technically, yes—but it’s not recommended. The Service Engine Soon light is a reminder, not a punishment. Ignoring it risks:

• Reduced engine life.
• Worse fuel economy.
• Higher repair costs.

Think of it like skipping a dentist cleaning. You might feel fine now, but cavities are brewing.

Q3: Does the reset work on all 2026 Infiniti models?

Yes, but the button location and exact sequence may vary slightly. The core method (ignition ON, hold trip button, confirm) works on:

• QX50, QX60, QX80
• Q50, Q60
• QX55

Always check your owner’s manual for model-specific details. Some trims (like the QX60 Sensory) have touchscreen controls for maintenance settings.

Q4: What if the trip button doesn’t work?

Try these fixes:

• Turn the ignition off, wait 30 seconds, and try again.
• Use an OBD2 scanner to reset the light electronically.
• Check for blown fuses (see owner’s manual for fuse box location).

If all else fails, visit an Infiniti service center. The instrument cluster may need software update or repair.

Q5: Is the OBD2 scanner method safer than the button method?

Both are safe when done correctly. The OBD2 method is better if:

• The button method fails repeatedly.
• You want to confirm no codes are stored.
• You’re resetting multiple alerts (e.g., oil, filter, tire pressure).

Just ensure your scanner supports Infiniti/Nissan protocols. Cheap generic scanners may not work.

Q6: How often should I reset the light?

Only after completing the recommended maintenance. For 2026 Infiniti models, typical intervals are:

• Oil change: Every 7,500 miles or 12 months (whichever comes first).
• Air filter: Every 30,000 miles.
• Cabin air filter: Every 15,000–20,000 miles (more often in dusty areas).

Resetting too often can confuse the system. Stick to the schedule.

Q7: Can I reset the light using the infotainment system?

On some 2026 models (like the QX60 Luxe), yes. Go to:

• Infotainment screen > Settings > Vehicle > Maintenance > Reset.

But the manual button method is faster and more reliable. Use the infotainment option as a backup.

Final Thoughts

Resetting the Service Engine Soon light on your 2026 Infiniti isn’t rocket science—but it does require attention to detail. Follow this How to Reset Service Engine Soon Light Infiniti 2026 Guide step by step, and you’ll keep your dashboard clean and your car running smoothly.

Remember: The light is your friend. It’s not there to scare you—it’s there to save you time, money, and stress. Reset it only after you’ve done the actual maintenance, and use an OBD2 scanner to double-check your work.

Now that you know the process, share it with a fellow Infiniti owner. A quick 10-minute reset could save them a $100+ dealership visit. And if you ever get stuck? Grab your owner’s manual, take a breath, and try again. You’ve got this.
