Welcome to the Subaru Technical Information System (STIS)!

This website offers two different technical information experiences. One section, referred to as "Online Reference", contains PDF-based Service Manuals and previously-printed Service material (such as Service Bulletins, Newsletters, Owners Manuals, etc.). The other area, called "Service Diagnostics", contains an HTML-based version of only our Service Manuals, which allow for easy location of diagnostic Service information via "troubleshooting trees" and offers the integration of Diagnostic Trouble Codes (DTC).

We hope that the new Diagnostics Service Information area will be of special value to Subaru Automotive Technicians repairing our vehicles. We make great efforts to constantly update our Service information, so we hope this resource will quickly replace your outdated printed repair manuals, becoming a very useful tool that you can count on to always be up-to-date.
