I need to do yearly maintenance at the dealer (or if I exceed some fixed mileage before that), they do the oil change in the course of that. If I would skip yearly maintenance the warranty is voided.

PS: that's for Mazda car.

That’s definitely not the case in the US (see Magnuson-Moss 1975) and many other countries have similar laws.
