Preventive maintenance

Know what deserves attention next.

Use this timeline to organize inspections and prepare questions. Your vehicle's factory maintenance schedule, oil-life system, warning messages, and service history always take priority.

Mileage + time checkpoints

Start with condition. Confirm with the manual.

Whichever limit comes first—time, mileage, a warning, or a failed inspection—deserves attention. “Inspect” does not automatically mean “replace.”

  1. 01
    Quick condition check

    Monthly + before long trips

    Any mileage

    Catch visible problems before they become roadside problems.

    • TiresCheck pressure when cold, visible damage, and uneven tread wear.
      Inspect
    • Lights and warningsConfirm exterior lights work and investigate new dashboard warnings.
      Inspect
    • Fluids and leaksLook for fresh spots under the vehicle and check accessible fluid levels.
      Inspect
    • Wipers and washer fluidReplace damaged blades and keep the reservoir filled.
      As needed
  2. 02
    Routine service checkpoint

    5,000-7,500 miles

    About 6-12 months

    Use the oil-life monitor or the exact interval in your owner's manual.

    • Engine oil and filterService only at the viscosity, specification, and interval required for your engine.
      Manual required
    • Tire rotationRotate using the pattern and interval approved for your tire and drivetrain setup.
      If specified
    • BrakesInspect pad life, rotor condition, hoses, and signs of pulling or vibration.
      Inspect
    • Tire pressureCheck all road tires and the spare if the vehicle carries one.
      Inspect
  3. 03
    Filters + wear items

    15,000-30,000 miles

    About 1-2 years

    Actual filter life changes dramatically with dust, traffic, weather, and mileage.

    • Engine air filterInspect for restriction or contamination; replace only with the correct fit.
      Inspect
    • Cabin air filterInspect or replace when airflow, odor, or the manufacturer interval calls for it.
      As needed
    • 12-volt batteryTest state of health and inspect the terminals, hold-down, and case.
      Test
    • Belts and hosesLook for cracking, glazing, swelling, leakage, or abnormal noise.
      Inspect
  4. 04
    Fluid decision point

    30,000-60,000 miles

    About 2-5 years

    Fluid type and service method must match the vehicle; universal advice is not enough here.

    • Brake fluidTest or replace only on the interval and fluid specification the manufacturer provides.
      Manual required
    • Transmission fluidInspect or service using the exact fluid and procedure for the transmission.
      Manual required
    • CoolantCheck condition, concentration, level, leaks, and the vehicle's replacement interval.
      Inspect
    • Driveline fluidsCheck differential, transfer-case, or transaxle service needs if equipped.
      If equipped
  5. 05
    Major wear checkpoint

    60,000-100,000 miles

    About 4-8 years

    Modern spark-plug and coolant intervals vary widely, so confirm the engine-specific schedule.

    • Spark plugsReplace only with the specified plug type, gap guidance, and torque procedure.
      If due
    • Serpentine belt systemInspect the belt, tensioner, idlers, alignment, and accessory-pulley noise.
      Inspect
    • Cooling systemCheck hoses, radiator, reservoir, cap, thermostat symptoms, and coolant interval.
      Inspect
    • Suspension and steeringInspect joints, bushings, boots, shocks or struts, and alignment symptoms.
      Inspect
  6. 06
    Protect the long-term owner

    90,000-120,000+ miles

    Higher-mileage review

    At higher mileage, condition and service history matter as much as the odometer.

    • Timing beltService only if the engine uses one and the manufacturer says it is due.
      If equipped
    • Mounts, seals, and hosesInspect age-related rubber deterioration, seepage, vibration, and leaks.
      Inspect
    • Wheel bearings and axlesInvestigate humming, looseness, torn boots, clicking, or vibration.
      Inspect
    • Complete history reviewCompare receipts and prior work with every remaining item in the factory schedule.

Severe-use reminder

Your driving conditions can shorten the schedule.

Many owner manuals publish a separate severe or special-use schedule. Check that section if any of these describe how the vehicle is used.

Make it vehicle-specific

Turn the baseline into your real schedule.

  1. 01Find the factory schedule

    Use the owner's manual, manufacturer owner portal, or service-information source for the exact year, model, engine, and drivetrain.

  2. 02Choose the correct use case

    Compare normal and severe-use definitions honestly. Time limits still matter when annual mileage is low.

  3. 03Record what was actually done

    Save the date, mileage, part or fluid specification, receipt, and any follow-up observation.
