Honda Civic Maintenance Minder codes
The 2024Honda Civic does not follow a printed mileage table. Its Maintenance Minder watches how the engine is used, works out the remaining oil life, and shows a code on the dash when service is due. Each code is a main item plus optional sub items.
| Code | What it covers |
|---|---|
| A |
|
| B |
|
| 1 |
|
| 2 |
|
| 3 |

- If a Maintenance Minder message does not appear more than 12 months after the display is reset, change the engine oil every year.
- If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
- If you drive primarily in urban areas with high concentrations of soot in the air from industry and diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
- Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures. If you regularly drive your vehicle under these conditions, have the transmission fluid changed every 25,000 miles (40,000 km).
- If a Maintenance Minder indicator does not appear more than 36 months after the display for item 7 is reset, change the brake fluid every 3 years.
A dash code combines a letter with digits: B12 means main item B plus sub items 1 and 2.
When the Civic shows maintenance messages

| Maintenance Due Soon | 15% to 6% | The engine oil is approaching the end of its service life; the listed items should be inspected and serviced soon. |
| Maintenance Due Now | 5% to 1% | The oil has almost reached the end of its service life; service the listed items as soon as possible. |
| Maintenance Past Due | 0%, negative distance shown | The oil life has passed. A negative distance appears after driving over 10 miles (U.S. models) and blinks. The listed items must be inspected and serviced immediately. |

Frequently asked questions
How often does a Honda Civic need an oil change?
Honda does not print a fixed mileage. The Maintenance Minder calculates remaining engine oil life from how the engine has actually been run and shows a code when service is due. Honda's guide says that if no Minder message appears more than 12 months after the display was reset, change the oil every year.
What do the Honda Civic Maintenance Minder codes mean?
A code is one main letter (A or B) plus sub item digits. A replaces engine oil. B replaces oil and filter and adds a set of inspections. The digits add rotation, filters, transmission fluid, spark plugs, coolant and brake fluid. The full table is on this page.
When does the Honda Civic show that maintenance is due?
The maintenance items appear when engine oil life drops to 15%, marked Due Soon. At 5% to 1% it shows Due Now, and after driving more than 10 miles past zero it shows a blinking negative distance, marked Past Due.
How often should Honda Civic brake fluid be replaced?
Honda's guide says that if no Minder indicator for item 7 appears more than 36 months after the display for that item was reset, change the brake fluid every 3 years.
Is this the same for earlier Civic model years?
Not necessarily. This page follows Honda's 2024 Civic guide. Sub item lists change between years and trims, so check the guide for your own year.
