Reset the service light on 2008 Porsche Cayenne

After changing the oil on my Porsche Cayenne I need to turn the service light off. If you could tell me how to do this it would be very helpful.

I am reading that it must be turned off with "PST2", or the Porsche System Tester 2. Seems like unfortunately you will need to take it to someone with this tool (dealer...or Porsche specialty shop) to reset it.
