The PHEV break-in section of the Australian warranty and service manual recommends the first service at 6 months or 3,500 km HEV Trip, whichever comes first. The HEV mileage condition and the vehicle’s total mileage are not the same figure.
For people who often commute entirely on electric power, the time condition is equally important; do not ignore the manual’s requirements just because the engine is used infrequently. Check the service schedule for your specific model, driving conditions, and subsequent routine maintenance intervals.
This post only summarizes this publicly available initial break-in requirement; it does not present it as a universal interval for all DM-i vehicles in every market.
