Why Is My Maintenance Required Light On? 5 Causes & Fix

The maintenance required light is a mileage-based countdown reminder — not a fault warning. It turns on automatically when your car has driven a set number of miles since the last service reset, almost always indicating an oil change is due. It does not mean something is broken.

What the Maintenance Required Light Is (And Isn't)

The maintenance required light (typically labeled "MAINT REQD" or shown as a wrench icon) is fundamentally different from the check engine light. It contains no diagnostic information — it's a simple odometer-based timer that resets every time a technician runs the reset procedure after a service.

The check engine light (engine outline, also orange or yellow) is triggered by an OBD-II trouble code from a specific malfunctioning sensor. If you're seeing an engine outline, not "MAINT REQD," this article is not the right diagnosis — have the code read first.

5 Reasons the Maintenance Required Light Is On

Oil Change Interval Reached

On most vehicles, the MAINT REQD light is calibrated to illuminate at the oil change interval — either a fixed mileage (3,000, 5,000, or 7,500 miles depending on vehicle and oil type) or a variable interval calculated by the car's oil life monitoring system.

Modern synthetic oils last 7,500–10,000 miles between changes. If your light came on and you recently changed your oil, the technician likely forgot to reset the counter.

Fix: Schedule an oil change if you haven't had one recently. If you have, ask the shop to reset the maintenance counter.

Multi-Point Service Interval

Some manufacturers program the MAINT REQD light to also illuminate at multi-point inspection intervals (often every 15,000 or 30,000 miles). These services typically include tire rotation, brake inspection, cabin air filter check, and fluid top-ups.

Fix: Consult your owner's manual for what services are due at your current mileage. A 30,000-mile service is more comprehensive than a routine oil change.

Light Wasn't Reset After Last Service

This is common. Shops manually reset the counter after service, but if they forgot, the light resets to the previous interval count and illuminates again within days. It looks like a new problem but is just an administrative miss.

Fix: Reset the light yourself using your vehicle's trip reset procedure (see the FAQ below for model-specific steps) or return to the shop and ask them to reset it.

Battery Was Disconnected or Replaced

On some vehicles, disconnecting or replacing the battery can trigger the maintenance light, even if no service is due. The car's computer loses memory state and defaults certain indicators.

Fix: Reset the maintenance counter using the trip reset procedure for your model.

The Car Is New to You (Used Vehicle)

If you recently purchased a used vehicle, the previous owner or dealer may have never reset the counter. The light may come on regardless of actual service history.

Fix: Check when the last oil change was documented (oil-change sticker in the door jamb or hood) against your current mileage. If service is due, get it done and reset. If not, just reset the counter.

How to Reset the Maintenance Required Light (2026)

Most reset procedures follow one of two patterns:

Toyota / Lexus (most models):
1. Turn the ignition key to On (not Start). Do not start the engine.
2. Locate the Trip Reset button on the instrument cluster (near the odometer).
3. Hold the Trip Reset button until the odometer display shows dashes or "000000."
4. Release the button. Turn the ignition off and back on to confirm the light is out.

Honda / Acura:
1. Turn the ignition to On.
2. Press and hold the Select/Reset button (usually on the steering wheel or instrument cluster).
3. Hold for 10 seconds until the maintenance indicator resets.

Most Other Makes (GM, Ford, Chrysler):
1. Turn the ignition to On.
2. Press the accelerator pedal fully three times within 10 seconds.
3. Turn ignition off and on to verify reset.

Always check your owner's manual under "Maintenance Reminder" or "Service Indicator Reset" for the exact procedure for your model year — minor variations exist even within the same manufacturer's lineup.

According to AAA, oil changes are the most critical routine maintenance for engine longevity. Running an engine on degraded oil is one of the top causes of premature engine wear in vehicles between 50,000–100,000 miles.

"Engine oil lubricates moving parts, reduces heat, and carries away contaminants. As oil ages and is contaminated, its protective properties degrade. Adhering to manufacturer oil change intervals — not necessarily the old 3,000-mile rule — is the most cost-effective engine protection." — AAA Automotive Research

In Short

The maintenance required light means one thing: a scheduled service interval has been reached. It is not a fault code. Schedule your oil change, get the service done, and have the counter reset. If the light came on within days of a recent service, the shop forgot to reset the counter — it takes 30 seconds to fix. Never confuse it with the check engine light, which requires an OBD-II scan to diagnose.

What You Also May Want To Know

What does the maintenance required light mean?

It's a mileage-based service reminder, not a mechanical warning. It illuminates automatically when your vehicle hits a set mileage since the last reset — typically indicating an oil change is due.

Is it safe to drive with the maintenance required light on?

Yes, briefly. The light is a reminder, not an emergency. Get the service done within the next 500–1,000 miles.

How do I reset the maintenance required light myself?

On most Toyota/Lexus: turn ignition to On, hold the Trip Reset button until the odometer shows 000000. On Honda: hold the Select/Reset button for 10 seconds with ignition On. Consult your owner's manual for your exact model.

What is the difference between the maintenance required light and the check engine light?

The maintenance required light is a mileage countdown timer with no diagnostic data. The check engine light is triggered by a specific OBD-II sensor fault. If you see an engine outline, not "MAINT REQD," have the code read.

What services does the maintenance required light cover?

On most vehicles it is tied to oil change intervals. Some models also factor in tire rotation, brake inspection, and multi-point inspections at 15,000 or 30,000-mile intervals.
