2021 Mazda CX-3 Maintenance Schedule
This is the last CX-3 Mazda sold in the U.S. Its tables are the nameplate’s settled ones — a Schedule 1 ceiling of 12 months or 7,500 miles and a severe table whose shortest rows fall every 5,000 miles — with the rear differential oil and transfer oil rows removed from both. This page states that model year’s own tables and no other year’s.
What Is Different About This Model Year
The reason this model year has its own page instead of being read off an earlier CX-3’s.
Mazda Published This Table for This Model Year Alone
Mazda revised the published schedule at this model year. It is also the last model year this research covers for the nameplate, so nothing after it is stated here either. What that means for the table below is set out in the cards that follow.
The Rear Differential and Transfer Oil Rows Are Gone
Both rows are removed from both of this model year’s schedules, and the submerged-in-water footnote goes with them. The model year before it prints both, and the one before that also carries a conditional 30,000-mile replacement. Mazda publishes nothing at all for them here, so this page states nothing — and the CX-3 was sold with all-wheel drive in every one of these years, so it is a question owners do ask.
The Kit Reads “If Equipped”
The emergency flat tire repair kit row is printed if equipped on this model year and if installed on the one before it, inspected annually either way, with a yearly check of the repair fluid expiration date. A wording change rather than an interval change, recorded so the two pages are not assumed identical because their numbers are.
Every Stated Interval Is Unchanged
Schedule 1 keeps its 12 month or 12,000 km (7,500 mile) ceiling, its 22,500-mile air filter and its 15,000-mile cabin air filter; Schedule 2 keeps its 5,000-mile disc brakes and its 25,000-mile cabin air filter. The boundary at this model year is a removed row, and a removed row is still a difference a page has to state.
What Mazda Never Scheduled for This Car
No CX-3 document in any model year prints a brake fluid replacement row — only a brake and clutch fluid level inspection — and none prints an automatic transmission fluid row or a fuel filter row. That was checked against both of this model year’s Mazda documents rather than assumed, and neither has them.

What Mazda asks for at your mileage

Updates Mazda has issued for your car

What was done, and what comes next
Schedule 1 — Normal Driving
This model year’s normal-driving table, grouped by the interval Mazda marks each row at.
Sourced from the Scheduled Maintenance (U.S.A., Canada, and Puerto Rico) section of the 2021 Mazda CX-3 owner’s manual, document CX-3_8JL1-EA-20G_Edition1, section pages 435 to 438, and from no other model year’s manual. Mazda’s standalone scheduled-maintenance document for this model year is character-identical to it, and both were checked for a brake fluid replacement row; neither has one. Your own manual is the authority for your vehicle; bring the mileage and our team will read the table with you. For this model year specifically, Mazda’s own book is document CX-3_8JL1-EA-20G_Edition1_old 2020-5-22 — the one to check your vehicle against.
Which Schedule Applies to Your CX-3
On this model year the answer is a property of the whole car, not of one row.
Mazda’s Own Condition List
Repeated short-distance driving; driving in dusty conditions; driving with extended use of brakes; driving in areas where salt or other corrosive materials are used; driving on rough or muddy roads; extended periods of idling or low-speed operation; driving for long periods in cold temperatures or extremely humid climates; driving in extremely hot conditions; driving in mountainous conditions continually. Mazda prints: follow Schedule 1 if none of these apply, and if any do apply, follow Schedule 2.
It Is the Whole Car, Not One Row
On this car a single condition moves the entire schedule to Schedule 2 — the oil, the disc brakes and every chassis row with it. Mazda’s newer books do something different and map each condition to specific items, leaving every other row on its normal interval. Two different models of severe service, and neither may be written the other one’s way.
Flexible and Fixed Are a Separate Question
Mazda prints, for this model year: engine oil flexible maintenance is selected by default for U.S.A. and Puerto Rico residents, and if either extended periods of idling or low-speed operation such as a police car, taxi or driving-school car, or driving in dusty conditions applies, follow Schedule 2 with engine oil fixed maintenance. So a dusty-conditions car is on Schedule 2 and on the fixed 5,000-mile oil interval rather than on the wrench light.
Rows That Are Not for This Market
Mazda routes Canada residents to Schedule 2 outright. That is a market routing rather than a statement about how a car is driven in Mobile, and it is not quoted as one here. Which of the two U.S. tables your CX-3 is on is a question about how it is driven, and our service team will go through the condition list with you.
Schedule 2 — Severe Driving
The severe-driving table for this model year.
Every 5,000 Miles or 6 Months
Engine oil and filter on the fixed basis, disc brakes, engine coolant level, brake and clutch fluid level, tire inflation pressure and tire wear, function of all lights, all locks and hinges lubricated, and washer fluid level. Tire rotation runs at the same cadence and is printed as a sentence: rotate every 8,000 km (5,000 miles).
Every 15,000 Miles or 18 Months
Fuel lines and hoses, brake lines, hoses and connections, steering operation and linkages, front and rear suspension with ball joints and wheel bearing axial play, driveshaft dust boots, and the bolts and nuts on the chassis and body. The same rows sit at every 15,000 miles or 24 months on Schedule 1 — the mileage matches and the month figure does not, which is exactly why the two tables are quoted separately.
Cabin Air Filter — 25,000 Miles
Mazda prints, on this model year’s Schedule 2: replace every 40,000 km (25,000 miles) or 2 years. That is the CX-3’s own figure and it is not the one Mazda prints for every other crossover of the same era, so a severe cabin filter borrowed from a showroom neighbour is wrong for this car. Schedule 1 replaces the cabin air filter every 15,000 miles or 24 months.
The Longer Severe Rows
Every 20,000 miles or 24 months — drive belts. Every 30,000 miles or 36 months — air filter, and hoses and tubes for emission. At 35,000 miles or 42 months, once — exhaust system and heat shields. Spark plugs and engine coolant carry the same figures they carry on Schedule 1, and the emergency flat tire repair kit is inspected annually. Mazda adds one note to the severe air filter row: if the vehicle is operated in very dusty or sandy areas, clean and if necessary replace the air filter more often than the recommended intervals.

Why This Model Year Has Its Own Page
It is the final U.S. CX-3, and the one whose tables drop the rear differential oil and transfer oil rows. Its intervals are the nameplate’s settled ones — a 7,500-mile Schedule 1 ceiling, a 22,500-mile air filter, 5,000-mile severe disc brakes — so what makes this page different from the one before it is which rows exist rather than which numbers they carry.
Schedule 1 and Schedule 2
Schedule 1 is the normal-driving table and hangs off a maximum interval of 12 months or 7,500 miles. Schedule 2 is the severe-driving table and marks its shortest rows at 6 months or 5,000 miles. On this model year’s wording a single severe condition moves the whole car onto Schedule 2.
Booking and Pricing
Service pricing moves, so it lives on the service offers page rather than being written into this one — what you read there is current. Book through the service scheduler, or see the rest of what we do at the Mazda service center.
2021 Mazda CX-3 Maintenance Schedule Questions
What is the maintenance schedule for a 2021 Mazda CX-3?⌄
Mazda prints two tables for this model year. Schedule 1, for normal driving, hangs off a maximum interval of 12 months or 12,000 km (7,500 miles) and marks each row at the columns it falls on. Schedule 2, for severe driving, runs on a grid of 6 months and 5,000 miles, with the disc brakes on every one of those columns.
How often is the cabin air filter replaced on a 2021 Mazda CX-3?⌄
Every 15,000 miles or 24 months on Schedule 1. On Schedule 2 Mazda prints: replace every 40,000 km (25,000 miles) or 2 years. The 25,000-mile severe figure is the CX-3’s own and holds across every model year of the nameplate.
When is the brake fluid replaced on a 2021 Mazda CX-3?⌄
Mazda does not schedule a brake fluid replacement for this car. Both of its published tables carry a brake and clutch fluid level inspection every 5,000 miles or 6 months on the severe schedule and no replacement row at all, and that was checked against both of Mazda’s documents for this model year. Where Mazda publishes nothing, this page states nothing and our service team will inspect and advise.
Does this page apply to an older CX-3?⌄
Only to this model year. The one before it still prints rear differential oil and transfer oil rows, and the earlier ones differ by more than that — different grids, a different oil ceiling and a different severe brake interval. Each CX-3 model year has its own page.
How much is maintenance for a 2021 Mazda CX-3 at Dean McCrary Mazda?⌄
Service pricing moves, so it lives on one page that is kept current rather than being written into pages like this one. Current offers are on the service offers page, and our service team will confirm the figure for your CX-3 when you book.
