The dreaded “Maintenance Required” light. It illuminates on your dashboard, often shortly after you’ve had an oil change, causing a moment of panic. Is something wrong with your car? Did the mechanic miss something? Most likely, no. This light is simply a reminder based on a predetermined interval, usually mileage or time, and it needs to be reset after the service is completed. Understanding how to turn off this light yourself can save you a trip back to the shop and empower you to maintain your vehicle more efficiently.
Understanding The Maintenance Required Light
The “Maintenance Required” light is not the same as the “Check Engine” light. The latter indicates a problem with your car’s engine or emissions system and requires diagnostic attention. The “Maintenance Required” light is a proactive reminder for routine services, with the oil change being the most common trigger. It’s a helpful feature designed to prevent neglecting essential maintenance tasks.
These lights are programmed at the factory with specific service intervals that vary from make to model. Consult your owner’s manual to understand the correct service schedule for your vehicle. While changing your oil, it is prudent to check other car fluids as well.
Ignoring the “Maintenance Required” light won’t immediately damage your vehicle, but prolonged neglect of necessary maintenance certainly will. Following the recommended maintenance schedule helps maintain your car’s performance, fuel efficiency, and longevity.
Why The Light Remains On After An Oil Change
The mechanic is responsible for turning off the light; however, mistakes happen. It’s a straightforward process, but it’s easy to overlook, especially in a busy shop. Another reason the light remains on is if you’re performing your own oil changes, you’ll need to know how to reset the system yourself.
Tools You Might Need
The tools needed to reset the maintenance light are minimal. Depending on your vehicle, you may only need:
- Your car key
- Your owner’s manual
For some vehicles, you might require:
- A scan tool (OBDII scanner) – particularly for models with electronic service reminders.
Step-by-Step Guide To Resetting The Maintenance Light
The reset procedure varies considerably between different car manufacturers and models. The following methods are common, but always refer to your owner’s manual for the specific instructions for your vehicle. Incorrect procedures could potentially affect other electronic systems.
Method 1: The Accelerator Pedal and Ignition Key Dance
This method is often used in older vehicles. While the exact steps can vary slightly, here’s a general outline:
- Turn the ignition key to the “ON” position (do not start the engine).
- Fully depress the accelerator pedal three times within five seconds.
- Turn the ignition off.
- Start the engine and see if the light has been reset.
If the light remains on, repeat the process or consult your owner’s manual for variations on this technique.
Method 2: Using The Trip Meter Reset Button
This is a common method used across various makes, including Toyota and Honda vehicles.
- Turn the ignition OFF.

Choosing The Right Oil
Selecting the correct type of oil is just as important as changing it regularly. Your vehicle’s owner’s manual will specify the recommended oil type and viscosity grade.
- Conventional Oil: The traditional type of motor oil, suitable for older vehicles or those with simpler engine designs.
- Synthetic Oil: A more advanced formulation that provides superior lubrication, protection, and performance, especially in extreme temperatures.
- Synthetic Blend Oil: A mixture of conventional and synthetic oils, offering a balance of benefits at a lower cost than full synthetic.
- High-Mileage Oil: Formulated specifically for vehicles with higher mileage, containing additives to help prevent leaks and reduce wear.
Using the wrong type of oil can negatively impact your engine’s performance and longevity. Always consult your owner’s manual and choose an oil that meets the manufacturer’s specifications.
Documenting Your Oil Changes
Keeping track of your oil changes is a good practice for maintaining your vehicle’s service history. This documentation can be helpful for warranty purposes and when selling the vehicle.
You can document your oil changes in several ways:
- Service Log: Keep a written record of each oil change, including the date, mileage, oil type, and any other services performed.
- Digital Records: Use a spreadsheet or a dedicated maintenance tracking app to record your oil changes electronically.
- Receipts: Save receipts from oil changes performed by a mechanic.
Having a clear record of your oil change history demonstrates your commitment to vehicle maintenance and can increase the resale value of your car.
