The fourth-generation Toyota Yaris Mk4 (XP210/P21) (2020–Present) moved onto the GA-B platform, bringing a far more efficient hybrid system and modern driver aids to the supermini. After a service its digital display expects the maintenance reminder reset, clearing the wrench once fresh oil and filter are fitted. Owners also run a TPMS reset so the tyre-pressure system relearns after a rotation, and clear the brake pad wear warning when new pads are installed. A steering angle calibration keeps the lane-keep and pre-collision systems accurate after alignment work. The hybrid’s 12V auxiliary battery sits in the boot; renewing it resets trip and clock data. Pick the service reset that suits your Yaris from the procedures listed directly below.
