Yeah, depends on the tire.
Odds are pretty good that if you show up with 42PSI in the front and 40 PSI in the rear you will be too high. Chalk your tires before the first run, i.e. make a line across the first tread block down to the sidewall of the tire in 2 places close to 180 degrees apart with a piece of chalk. Inspect the line after your run. The chalk should be worn off to the edge of the tread but not beyond it. If the chalk isn't worn off to the edge of the tread drop pressure slowly until it is in 1-2 PSI increments after every run. If you have a compressor to add air if you let too much out you can guess directly at the right pressure and adapt up and down.
The odds are pretty good that your ideal pressure for neutral(ish) handling in your Accent with a street tire will be about 36-38PSI in the front and 32-35PSI in the rear. But, don't just fill up to that range and hope, like faith said it depends on the tire and that can make a huge difference.
If your rear is sliding around a lot on you letting a bit more air out of the rears tends to help, just don't overdo it.
