When to service & replace parts
A year-by-year plan for the routine jobs. Service earlier when the dashboard mileage reminder is due.
| When | Service | What to do |
|---|---|---|
| Year 1 | Service A |
|
| Year 2 | Service B |
|
| Year 3 | Service A |
|
| Year 4 | Service B |
|
| Year 5 | Service A |
|
| Year 6 | Service B |
|
Service sooner if the dashboard kilometre limit is reached before the year is up. This pattern starts with the first service. Use your service history to find your place in the cycle; count separate fluid and filter intervals from their last change.
Replacement intervals
| Part or fluid | When to replace it |
|---|---|
| Engine oil and oil filter | Every 1 year, or sooner if shown on the dashboard |
Replace according to wear
Brake pads, discs, tyres and wipers do not share a fixed replacement mileage.
Brake pads and discs
Check pad thickness and disc condition. Replace when they reach the wear limit.
Wiper blades
Replace blades that leave streaks, skip across the glass or have damaged rubber.
Tyres
Check tread, damage and cracking, and correct the pressures.
Service checklist
Service A and Service B alternate, normally once a year. Follow the time or kilometres remaining on your dashboard, whichever comes first. Extra work can fall due with either service.
