Maintenance and records
≈: estimated reference — the vehicle’s service indicator prevails.
Brakes: pads and discs
Every year
Check every year. Regenerative braking spares the pads, but discs can rust or seize from lack of use: an annual check is advised.
Source [1]Cabin filter
≈ 30,000 km or 2 years
Every 1 to 2 years. Replace more often in town or if odours appear; it also protects the air conditioning and heat pump.
Source [1]Tyres: wear and rotation
Every year
Regular checks, rotation about every 10,000–15,000 km. An EV’s torque and weight wear tyres faster: watch the pressure and rotate them for even wear.

≈ 60,000 km or 2 years
At each manufacturer service. Battery, cables and cooling are checked by diagnosis; qualified workshop only.
