Update: There is a great thread located here at DSMTuners.com | DSM Maintenance Guide

Any dealer can tell you this. You can also obtain a copy of the owners manual for your year, make and model car from Mitsubishi or Chrysler. It's pretty much a typical regimen of changes for oil, filters, plugs and belts. You can also get a shop manual for your car which details the wheres, whens and hows for the various procedures.

There is now some maintenance information in this FAQ.

New owners: PLEASE read the Recalls section of this FAQ to inform yourself about important potential problems. Also note that timing AND balance shaft belts REALLY should be changed by 60 kmiles (90 kkm), so used-car owners will want to check that right away.
