This guide walks you through the simple process of resetting the engine oil light on a Lexus IS 250. You’ll save time and avoid unnecessary trips to the dealership by following our clear, easy-to-follow instructions.
Key Takeaways
- Know your model year: The reset method varies slightly between 2006–2013 and 2014–2015 IS 250 models, so confirm your vehicle’s year first.
- Use the trip meter button: This is the primary tool for resetting the oil light—no scan tools or dealership visits needed.
- Turn the ignition to “ON” but don’t start the engine: This powers the dashboard without engaging the motor, allowing access to maintenance settings.
- Cycle through display modes: Use the trip button to navigate to the oil life percentage screen before initiating the reset.
- Hold the button for 10–15 seconds: Patience is key—release only when the oil light blinks or resets to 100%.
- Verify the reset worked: Turn the car off and back on to confirm the oil light no longer appears on the dashboard.
- Regular maintenance prevents warnings: Resetting the light doesn’t replace oil changes—stick to your scheduled service intervals.

Why Does the Oil Light Come On?

Before we dive into the reset process, it’s important to understand why the oil light appears in the first place. The Lexus IS 250 is equipped with an advanced oil life monitoring system that tracks your driving habits, engine temperature, mileage, and other factors to determine when an oil change is needed.
Unlike older cars that rely solely on mileage (e.g., “change oil every 3,000 miles”), the IS 250 uses real-time data to estimate oil degradation. This means the oil light might come on after 5,000 miles for one driver and 7,500 for another—depending on how they drive.
When the system calculates that the oil has reached the end of its useful life, it triggers the “Oil Maintenance Required” or “Check Engine” light on your dashboard. This is your cue to get an oil change. However, after the oil is changed, the system doesn’t automatically reset. That’s where you come in.
Resetting the oil light tells the car’s computer that fresh oil has been installed and resets the oil life percentage back to 100%. If you skip this step, the light will remain on—even though your oil is clean and full.
Tools and Preparation
The beauty of resetting the IS 250 oil light is that you don’t need any special tools. Everything you need is already in your car. Here’s what to gather before you begin:
- Your Lexus IS 250 (obviously!)
- The key fob or physical key
- A few minutes of uninterrupted time
Make sure your car is parked on a level surface and the engine is off. You don’t need to raise the car or access the engine bay—this is a dashboard-only procedure.
Also, confirm that you’ve actually changed the oil. Resetting the light without fresh oil defeats the purpose and could lead to engine damage over time. If you’re unsure whether the oil was changed, check the dipstick or ask the technician who performed the service.
Step-by-Step Guide to Reset the Oil Light
Now that you’re prepared, let’s walk through the reset process. The steps differ slightly depending on your IS 250’s model year, so we’ll cover both the 2006–2013 and 2014–2015 versions.
For 2006–2013 Lexus IS 250 Models
If your IS 250 was manufactured between 2006 and 2013, follow these steps:
Step 1: Turn the Ignition to “ON”
Insert your key into the ignition and turn it to the “ON” position. This powers up the dashboard and electronics, but does not start the engine. You should see all the warning lights illuminate briefly—including the oil light.
Do not press the brake pedal or start the engine. We only want the ignition on.
Step 2: Locate the Trip Meter Button
Look at your instrument cluster, just below the speedometer. You’ll see a small button labeled “TRIP” or “ODO/TRIP.” This button cycles through different display modes, including trip distance, average fuel economy, and oil life percentage.
Press this button repeatedly until you see “OIL LIFE” or a percentage (e.g., “OIL LIFE 15%”) on the screen.
Step 3: Press and Hold the Trip Button
Once the oil life percentage is displayed, press and hold the trip button. Keep holding it for about 10 to 15 seconds.
You’ll notice the percentage start to count down or the display may blink. This is normal. Continue holding the button until the oil life resets to 100% or the oil light turns off.
Step 4: Turn Off the Ignition
Once the reset is complete, release the button and turn the ignition back to the “OFF” position. Wait about 10 seconds, then turn it back to “ON” to verify the reset.
The oil light should no longer be illuminated. If it is, repeat the process.
For 2014–2015 Lexus IS 250 Models
The 2014 and 2015 IS 250 models use a slightly different interface, but the process is just as simple.
Step 1: Turn the Ignition to “ON”
As with earlier models, turn the key to the “ON” position without starting the engine. All dashboard lights should light up.
Step 2: Access the Multi-Information Display
These newer models use a multi-information display (MID) screen in the instrument cluster. Use the steering wheel controls to navigate to the “Settings” or “Vehicle Settings” menu.
Look for an option labeled “Maintenance” or “Oil Maintenance.”
Step 3: Select “Reset” or “Initialize”
Once you’re in the maintenance menu, select the option to reset the oil life. You may need to confirm by pressing “OK” or holding a button.
The system will reset the oil life to 100%, and the warning light should disappear.
Step 4: Confirm the Reset
Exit the menu and turn the ignition off. Wait a few seconds, then turn it back on. Check that the oil light is no longer active.
Practical Tips for a Smooth Reset
Even though the process is straightforward, a few tips can help ensure success:
- Be patient: Holding the button for the full 10–15 seconds is crucial. Rushing can cause the reset to fail.
- Don’t start the engine: The reset only works when the ignition is on but the engine is off. Starting the car interrupts the process.
- Check your model year: Using the wrong method for your IS 250 can lead to confusion. Double-check your vehicle’s production year before beginning.
- Use the correct button: Some drivers accidentally press the odometer reset instead of the trip button. Make sure you’re using the right one.
- Try twice if needed: If the light doesn’t reset the first time, don’t panic. Turn the car off, wait 30 seconds, and try again.
Troubleshooting Common Issues
Sometimes, the oil light reset doesn’t work as expected. Here’s how to fix the most common problems:
The Light Won’t Turn Off
If the oil light remains on after following the steps, try these fixes:
- Ensure the ignition is in the correct position. Some drivers accidentally start the engine, which cancels the reset.
- Check that you’re holding the trip button long enough. Count to 15 slowly.
- Try the process with the driver’s door open. On some models, this helps activate the reset mode.
- If all else fails, disconnect the car battery for 10 minutes. This resets the entire ECU and often clears stubborn warning lights.
The Oil Life Percentage Doesn’t Appear
If you can’t find the oil life display:
- Cycle through all trip modes by pressing the button multiple times. The oil life screen may be buried under other options.
- Consult your owner’s manual. Some IS 250 trims have slightly different menu layouts.
- Ensure the car is in “ON” mode. The display won’t show maintenance data if the ignition is off.
The Light Comes Back On Immediately
If the oil light resets but returns the next time you drive:
- You may have a faulty oil pressure sensor. This is rare but possible. Have it checked by a mechanic.
- The oil change wasn’t recorded properly. Some shops forget to reset the system—double-check with them.
- There could be an actual oil problem, such as low oil level or dirty oil. Check the dipstick and top off if needed.
When to Seek Professional Help
While resetting the oil light is a DIY-friendly task, there are times when you should consult a professional:
- If the oil light is red (not yellow or orange), it may indicate low oil pressure—a serious issue that requires immediate attention.
- If the “Check Engine” light is also on, there could be an underlying mechanical problem beyond the oil change.
- If you’ve tried the reset multiple times and it fails, there may be a software glitch or electrical issue in the instrument cluster.
In these cases, it’s best to visit a Lexus service center or trusted mechanic. They can run a full diagnostic and ensure your IS 250 is in top condition.
Maintaining Your IS 250 for Long-Term Health
Resetting the oil light is just one part of vehicle maintenance. To keep your IS 250 running smoothly, follow these best practices:
- Change oil every 5,000–7,500 miles: Even with the oil life monitor, don’t exceed 7,500 miles between changes.
- Use the right oil: Lexus recommends synthetic 0W-20 or 5W-30 oil for the IS 250. Check your owner’s manual for specifics.
- Replace the oil filter: Always install a new filter with each oil change to prevent contamination.
- Check oil levels monthly: Low oil can trigger the warning light even if the oil is fresh.
- Keep service records: This helps track maintenance and can increase resale value.
