📚 Vehicle History

Subaru Heritage:

Subaru, a division of Subaru Corporation (formerly Fuji Heavy Industries), has a history of engineering innovative AWD systems and unique horizontally-opposed ('Boxer') engines.

First Generation Bg Bh:

The Subaru Outback originated from the Subaru Legacy wagon. The BG generation (1999-2000) was a facelifted Legacy with increased ground clearance and body cladding. The BH generation (2000-2004) continued this theme, offering a distinct identity with a raised suspension and rugged styling, available with 2.5L and 2.5L Turbo engines.

Second Generation Bp Bl:

The BP/BL generation (2005-2009) saw a redesign on a new platform, moving slightly upmarket. Engine options included 2.5L naturally aspirated and turbocharged, and the new 3.0L EZ30D H6 engine for the 3.0R trim. This generation featured improved interior refinement and more advanced safety features.

Third Generation Br Bm:

The BR/BM generation (starting 2010) marked a significant redesign, becoming larger and more SUV-like. This generation introduced the 3.6L EZ36D H6 engine and further refinements in styling and technology. This manual covers the initial year of this generation.

Manufacturing Location:

Primarily manufactured in Japan. Some models may have had assembly in other locations depending on market.

🏆 Awards & Recognition

Car And Driver 10Best:

The Outback, particularly the turbocharged GT models and H6 variants, frequently appeared on Car and Driver's '10Best' lists during various years in this period for its blend of performance, utility, and AWD capability.

Safety Awards:

Consistently received good safety ratings from IIHS and NHTSA, contributing to its reputation as a safe vehicle.

Trail Rated Equivalency:

While not officially 'Trail Rated' like Jeep vehicles, its standard AWD and higher ground clearance gave it significant off-pavement capability that appealed to outdoor enthusiasts.
