There is no reset switch ... it's a warranty/mileage item in the memory module. When the light comes on, instead of taking the vehicle in for service, try diconnecting the battery for about five (5) minutes before reconnecting it. The light should go out. If it doesn't, then a technician needs to check your system. I've had to reset the light on my 2000 Grand Marquis 3 or 4 times already.

If you disconect the battery for 15 seconds and that does not make it go out then you will have to take it to some who can reset your computer.
if you have an autozone close by they can read, reset/clear any codes you have on your ecm..
The '96 and newer, I believe, need an OBD II scan tool. Don't just jumper the ALDL under the dash or you'll blow your PCM. The SES light coming on is the PCM telling you there is a problem somewhere in the system, and you should get the code to see where it is. Fixing it will shut that light off, after resetting the PCM (disconnect battery for 15 seconds, or pull the PCM B fuse for same time and then replace).
this may be random but i had to post just in case (i own a 94 sl2) i had put an after market air filter on the car, and removed the IAT sensor on the snorkle, that made my "service engine soon" light come on, put the iat back on, light went away, AND this was during a period where i disconnected the battery every night so i do not believe the battery trick is gonna help you in a Saturn...unless you truly DONT have a car problem that needs to be fixed, but if you do, then that light is not going to go away until you remedy that problem.
