The maintenance light in your vehicle is there for a reason—it reminds you when it is time for scheduled service, such as an oil change or other routine maintenance. While the light itself is not an emergency warning, ignoring it can lead to missed maintenance intervals that affect performance and longevity.
After the required service has been performed, the light needs to be reset. In many cases, this is a simple process you can do yourself, but it varies from one vehicle to another. Knowing how to reset your maintenance light helps keep your service reminders accurate and your vehicle’s maintenance schedule on track.
Why the Maintenance Light Comes On
The maintenance light is triggered by your vehicle’s onboard computer, usually based on mileage, time since the last reset, or a combination of both. For example, if your oil change interval is set for 5,000 miles, the light will appear once you hit that mileage, regardless of the oil’s actual condition.
In newer vehicles, maintenance reminders may be more advanced and can monitor oil life based on driving conditions, temperature, and engine load. Still, the principle remains the same: the light is there to prompt you to schedule service.
When to Reset the Light
You should only reset the maintenance light after the recommended service has been completed. Resetting it without actually performing maintenance defeats the purpose and can cause you to miss important service intervals.
For example, if you reset the oil change reminder without changing the oil, you risk running the engine with degraded oil, which can lead to premature wear or damage.
How to Reset the Light
The steps to reset a maintenance light vary by make and model. However, most follow one of these general methods:
Method 1: Using the Ignition Key
- Turn the key to the “ON” position without starting the engine.
- Locate the reset button or trip odometer button on the dashboard.
- Press and hold the button until the maintenance light begins to flash or turn off.
- Turn the ignition off, then back on to confirm the reset.
Method 2: Using the Menu Screen
- Turn the ignition to “ON” or press the start button without pressing the brake pedal.
- Navigate to the settings or vehicle info menu using the steering wheel controls.
- Select “Maintenance” or “Oil Life.”
- Choose the “Reset” option and confirm.
Some vehicles require a combination of pedal presses or button sequences, which are detailed in the owner’s manual.
When a Reset Requires a Scan Tool
On certain newer vehicles, the maintenance reminder system may need to be reset using a diagnostic scan tool. This is more common in luxury brands and models with advanced maintenance tracking systems. Your mechanic can perform this reset during routine service.
Why It’s Important to Keep Reminders Accurate
The maintenance light is more than just a visual alert—it is a tool to help you protect your investment. Keeping it accurate ensures you never miss essential services like oil changes, tire rotations, and filter replacements.
If the light is ignored, reset incorrectly, or reset too early, you may end up with an inaccurate maintenance history. This can not only affect your vehicle’s health but also reduce its resale value if service records are incomplete or inconsistent.
Preventive Maintenance Matters
Resetting your maintenance light is only part of the equation. Performing the actual maintenance on time is what truly matters. Following your manufacturer’s recommended schedule helps prevent costly repairs, maintains performance, and keeps your warranty valid if applicable.
