how do you tell the difference in the models of a 2002 nissan xterra

The XE edition came with a roof rack, A/C, a CD player, anti-lock brakes, and a full-size spare and was available with a 4- or 6-cylinder engine. The SE came with the V6, power doors, locks, and windows, cruise control, fog lamps, step rails, tilt steering, a 6-CD changer, a first-aid kit, and 16-inch wheels. The supercharged V6 was available for both the XE and SE, and SEs with the supercharged engine had 17-inch wheels. Hope that helps!
