For all versions of the Verna ... location is inside the dashborad and behind the glove compartment. But AFAIK, it isnt present on base models. The place is there, but no filter. Same problem with base models of Swift And SX4.
But i don see any dust settled anywhere inside my verna!! Now i understand i why there used to be loads of dust on all the knobs and the buttons in the dashboard in my safari!! Maybe safari doesn have this!!
