Heads-up display arrangements for vehicles including a seat in which an occupant sits, a system for forming an image of text and/or graphics in a field of view of the occupant, a determination arrangement for determining a position of the occupant (or a part thereof) and an adjustment system for adjusting the seat based on the occupant's determined position to thereby change the orientation of the occupant relative to the image. Change of the orientation of the occupant relative to the image may entail adjusting the seat and/or adjusting the image forming system, which is often a heads-up display system. Adjustment of the seat may involve moving the seat forward or backward and/or up or down, or any other direction or way possible given the construction of the seat.
