optimal oil life change interval depending on the vehicle driving conditions and weather events.
It needs to be performed in the following cases:
1. If the service lamp is on, run car diagnostics first for troubleshooting. After that, reset the driving
mileage or driving time, so as to turn off the service lamp and enable a new driving cycle.

oil life, you need to reset the service lamp.
