You don't!
If part of the mat is still flat, the best you could do would be to cut out the warped section, and make some smaller mats.
The mats need to be stored flat.
If transported in a car, laying it flat is important too, as the heat coming thru the glass can warp it.
Touching the mat with a hot iron can do it as well.
