Mazda CX-5 Maintenance Schedule (KF, 2019–2021)

On the 2019–2021 CX-5 (KF), Mazda's US schedule has you replace the engine oil and filter when the wrench indicator light comes on, and at least once every 12 months or 7,500 miles (12,000 km) since the last change. The spark plugs are replaced every 75,000 miles (120,000 km) on the 2.5L, but every 40,000 miles (64,000 km) on the 2.5L Turbo. The coolant is first replaced at 120,000 miles (192,000 km) or 10 years.

This guide covers the second-generation (KF) CX-5 in the 2019, 2020 and 2021 model years, with the 2.5L SKYACTIV-G, the 2.5L SKYACTIV-G Turbo and, for 2019 only, the 2.2L SKYACTIV-D diesel. The figures come from Mazda's US scheduled maintenance booklets for those three years and the 2019 owner's manuals. It does not cover CX-5s from before the 2019 model year, from 2022 onward or the first generation, and this page gives no figures for them.

Quick reference: KF CX-5 schedule

These are the normal (Schedule 1) values. Mazda marks items R (replace), I (inspect) or, for the diesel air filter, C (clean), and this guide keeps those verbs. The 2019 diesel has its own rows, covered in its own section.

Schedule 1 and Schedule 2

Mazda's US schedules come in two parts. Schedule 1 is the normal one, and the table above uses it. Schedule 2 is for severe use and has its own fixed intervals for several items. Most are shorter, but its cabin and engine air filter mileages are higher than Schedule 1's.

For the oil, Mazda names the severe conditions: extended idling or low-speed operation, such as a police car, taxi or driving school car, and dusty conditions. The Schedule 2 values for the other items are given with each item below. They are separate from the normal values and are never folded into them.

Engine oil, filter and tire rotation

Engine oil and filter. The US default is Mazda's Engine Oil Flexible Maintenance. Replace the oil and filter when the wrench indicator light comes on, and at least once every 12 months or 7,500 miles (12,000 km) since the last change. Reset the oil data after every change.

With extended idling or low-speed operation, or in dusty conditions, Mazda uses fixed maintenance instead: replace the oil and filter every 5,000 miles (8,000 km) or 6 months.

Tire rotation. Rotate the tires every 7,500 miles (12,000 km). Under Schedule 2, rotate every 5,000 miles (8,000 km). Mazda gives no time limit for rotation.

Filters, spark plugs, coolant and drive belts

Engine air filter. On the 2.5L and the 2.5L Turbo, Mazda marks it R at 22,500 miles (36,000 km) or 36 months, and again at 45,000 miles (≈72,000 km) or 72 months. Under Schedule 2, replace it every 30,000 miles (48,000 km) or 36 months. In very dusty or sandy areas, Mazda says to clean it, and if necessary replace it, more often.

Cabin air filter. Schedule 1 marks R every 15,000 miles (≈24,000 km) or 24 months. Under Schedule 2, the interval changed between model years: the 2019 schedule says every 25,000 miles (40,000 km) or 2 years, and the 2020 and 2021 schedules say every 30,000 miles (48,000 km) or 2 years.

Spark plugs. The two gasoline engines have different intervals. On the 2.5L SKYACTIV-G, replace the plugs every 75,000 miles (120,000 km). On the 2.5L SKYACTIV-G Turbo, replace them every 40,000 miles (64,000 km). Mazda gives the same interval under severe conditions, and no time limit. Mazda labels the 75,000-mile row as every engine except the Turbo. On the gasoline CX-5, that means the 2.5L SKYACTIV-G, so check which engine your CX-5 has before using either figure.

Engine coolant. The first replacement is at 120,000 miles (192,000 km) or 10 years. After that, replace it every 60,000 miles (96,000 km) or 5 years. The interval is the same under severe conditions. Mazda recommends FL-22 coolant and warns that other coolant may seriously damage the engine and cooling system.

Drive belts. On the 2.5L and the 2.5L Turbo, this is an inspection, not a replacement. Schedule 1 marks I at 22,500 miles (36,000 km) or 36 months, and again at 45,000 miles (≈72,000 km) or 72 months. Under Schedule 2, inspect them every 20,000 miles (≈32,000 km) or 24 months.

Brakes, steering and suspension

Brake items are inspections. Mazda marks the disc brakes I every 7,500 miles (12,000 km) or 12 months, and the brake lines, hoses and connections I every 15,000 miles (≈24,000 km) or 24 months. Under Schedule 2, inspect the disc brakes every 5,000 miles (8,000 km) or 6 months, and also inspect the brake fluid level.

Steering and suspension are inspected every 15,000 miles (≈24,000 km) or 24 months, and the interval is the same under severe conditions. Mazda lists steering operation and linkages, the front and rear suspension, ball joints, wheel bearing axial play and the driveshaft dust boots.

The 2019 diesel (2.2L SKYACTIV-D)

Mazda sold the 2.2L SKYACTIV-D diesel in the CX-5 Signature AWD for the 2019 model year. The 2020 and 2021 scheduled maintenance booklets still print diesel rows, but Mazda's 2020 and 2021 CX-5 releases list only the 2.5L and the 2.5L Turbo, so the diesel rows below are for 2019 only. The diesel follows the same oil, tire rotation, coolant, brake and steering rows as the gasoline engines. It has its own rows for the following:

• Air filter: clean every 7,500 miles (12,000 km) or 12 months, and replace every 22,500 miles (36,000 km) or 36 months. Under Schedule 2, clean every 5,000 miles (8,000 km) or 6 months and replace every 30,000 miles (48,000 km) or 36 months. In very dusty or sandy areas, clean it and if necessary replace it more often.
• Fuel filter: replace every 22,500 miles (36,000 km) or 36 months. Under Schedule 2, replace every 20,000 miles (≈32,000 km) or 24 months.
• Drive belts: inspect every 22,500 miles (36,000 km) or 36 months. Under Schedule 2, inspect every 10,000 miles (≈16,000 km) or 12 months.
• Diesel exhaust fluid: top up the urea tank with new fluid once a year. At 36 and 72 months, check the mileage of the last three years. If it is 12,000 miles (19,200 km) or more, top up. If it is less than 12,000 miles (19,200 km), replace the fluid in the urea tank.
• Glow plugs: replace them when the glow indicator light stays on.

What Mazda does not schedule for the CX-5

Several items that generic checklists include have no interval in the US schedules in Mazda's booklets for these years:

• Brake fluid replacement. There is no row in either schedule. Schedule 2 only inspects the brake fluid level.
• Automatic transmission fluid. There is no row in the 2019, 2020 or 2021 US schedules.
• Rear differential oil and transfer oil (AWD). There is no mileage interval. The 2019 and 2020 schedules list both items with a note that the oil should be replaced if the component has been submerged in water, and the 2021 schedule drops both rows.
• Battery. There is no battery interval in the US scheduled maintenance.
• Fuel filter on the gasoline engines. Only the diesel has a fuel filter row.

If a shop quotes one of these as factory scheduled, ask which page of the owner's manual or maintenance booklet it comes from.
