The “Maintenance Required” light on your vehicle’s dashboard is a common sight, and it can be a source of frustration and anxiety. However, it doesn’t always mean that there is a major problem with your car. In many cases, it is simply a reminder that some routine maintenance is due. In this article, we’ll show you how to clear the “Maintenance Required” light without having to take your car to a mechanic. We’ll also provide some tips on how to avoid getting the light in the future.
If you see the “Maintenance Required” light on your dashboard, the first thing you should do is check your vehicle’s owner’s manual. The manual will tell you what the light means and what steps you need to take to clear it.

1. Check the Oil Regularly
One of the most important things you can do to keep your car running smoothly is to check the oil regularly. The oil lubricates the moving parts in your engine, and if it gets too low, it can cause serious damage. Check your oil level at least once a month, and add oil as needed.
2. Change the Oil and Filter Regularly
In addition to checking the oil level, you should also change the oil and filter regularly. This will help to remove dirt and contaminants from the oil, and it will keep the engine running cleanly. The oil change interval will vary depending on your car, so be sure to consult your owner’s manual for specific instructions.
3. Keep the Tires Inflated to the Correct Pressure
Underinflated tires can cause a number of problems, including increased fuel consumption, poor handling, and premature wear. Check the tire pressure regularly, and inflate the tires to the correct pressure as specified in your owner’s manual.
4. Rotate the Tires Regularly
Rotating the tires helps to ensure that they wear evenly, which can prolong their lifespan. The tire rotation interval will vary depending on your car, so be sure to consult your owner’s manual for specific instructions.
5. Get Regular Brake Inspections
The brakes are one of the most important safety features on your car, so it’s important to get them inspected regularly. A brake inspection will check the brake pads, rotors, and calipers for wear and damage. If any problems are found, they can be repaired before they become more serious.
6. Replace the Air Filter Regularly
A dirty air filter can restrict airflow to the engine, which can lead to reduced performance and fuel economy. Replace the air filter according to the manufacturer’s recommended interval, or more often if you drive in dusty or polluted conditions.
7. Get Regular Tune-Ups
A tune-up can help to improve your car’s performance and fuel economy. A tune-up will typically include replacing the spark plugs, air filter, and fuel filter. It may also include adjusting the timing and fuel mixture.
8. Drive Conservatively
The way you drive can have a big impact on the maintenance needs of your car. Avoid aggressive driving habits, such as speeding, hard braking, and rapid acceleration. These habits can put extra stress on the engine, transmission, and brakes.
9. Keep Your Car Clean
A clean car is more likely to be well-maintained. Wash your car regularly, and pay attention to areas that are prone to rust, such as the undercarriage and wheel wells.
10. Follow the Maintenance Schedule in Your Owner’s Manual
The best way to prevent maintenance issues is to follow the maintenance schedule in your owner’s manual. This schedule will tell you when to perform specific maintenance tasks, such as oil changes, tire rotations, and brake inspections. By following the maintenance schedule, you can help to keep your car running smoothly for many years to come.
