Request the hearing.  If you do not the DMV will automatically suspend your driving priviledges. There are a couple of ways the request can help.  First, it is an opportunity to question the officer without a prosecuting attorney present This is a great opportunity to gather evidence to use in your future criminal proceeding.Second, if the officer does not show for the hearing, which they have been known to do, you will not lose your license. At least at the DMV stage.Request the hearing and show up for it.  It cannot hurt.Hope this helps
