2006 SUBARU Legacy, Legacy Station Wagon, and Outback Station Wagon Owner’s Manual (P/N A2440BE-A)

This 438-page Subaru Owner’s Manual carries publication code A2440BE-A and the edit date December 6, 2006. The date shown is the document edit date; fit should be confirmed by publication code and vehicle configuration. The opening coverage page lists Legacy Sedan, Legacy Station Wagon, and Outback Station Wagon for North America. Later tables also separate Legacy and Outback sedan/wagon data by engine and equipment, along with U.S. and Canadian instrument layouts. Some content applies only to vehicles so equipped. The supplied file is a PDF of the fourteen-chapter publication.

This is an owner’s manual—not a factory repair manual. Its scope is vehicle operation, owner-level maintenance, emergency work, system warnings, capacities, and specifications. It does not provide internal engine or transmission repair, circuit-level wiring schematics, scan-tool fault trees, or full removal and overhaul procedures. Subaru directs repairs and adjustments outside this manual’s scope to a dealer. Detailed service intervals are assigned to the separate Warranty and Maintenance Booklet, and navigation operation is referred to a separate supplement. Do not treat this publication as a repair manual for teardown or electrical diagnosis.

Vehicle and Powertrain Coverage

• Factory engine codes are EJ253 (2.5-liter SOHC non-turbo), EJ255 (2.5-liter DOHC turbo), and EZ30D (3.0-liter DOHC six-cylinder). Specifications include displacement, bore and stroke, compression ratio, firing order, and NGK plug numbers FR5AP-11, SILFR6A, and ILFR6B.
• Transmission coverage includes the 5-speed manual, 6-speed manual for the 2.5GT spec.B, 4-speed automatic, and 5-speed automatic. Operating sections explain manual mode, shift-lock and reverse-inhibiting functions, SPORT mode, and SI-DRIVE Intelligent, Sport, and Sport Sharp modes for turbo and 3.0-liter models.
• Chassis and driver-assist content covers AWD operation, the rear viscous limited-slip differential where equipped, ABS, Electronic Brake Force Distribution, Vehicle Dynamics Control, TPMS, cruise control, and brake-pad wear indicators. The U.S. emissions section explains how CHECK ENGINE/MIL operation, stored diagnostic trouble codes, and OBD readiness status affect inspection, including the “more than one Not Ready” rejection condition.

Maintenance and Specification Depth

Separate engine-compartment views identify the 2.5-liter non-turbo, 2.5-liter turbo, and 3.0-liter layouts. The maintenance chapter covers engine oil/filter and coolant service, the air cleaner, spark plugs, drive belts, manual and automatic transmission lubricants, front and rear differential oil, power-steering fluid, brake and clutch fluid, pedal checks, tires, wipers, battery, fuses, and bulbs.

Hard data includes:

• Engine oil: 4.2 US qt for 2.5-liter models and 5.8 US qt for 3.0-liter models.
• Transmission lubricant: 3.7 US qt for the 5-speed manual, 4.3 US qt for the 6-speed manual, 9.8 US qt ATF for 2.5-liter non-turbo models, and 10.4 US qt ATF for turbo and 3.0-liter models.
• Cooling system: 6.7–7.7 US qt, depending on engine and transmission. The manual also specifies API GL-5 manual/differential oil, fresh DOT 3 or DOT 4 brake and clutch fluid, and 74–89 lbf·ft (100–120 N·m) wheel-nut torque.

Tire tables cover P205/55R16 through 215/45R18 applications, model-specific pressures, 60 psi temporary-spare data, alignment values, and trailer-towing rear pressures. Fuse charts map 33 passenger-compartment positions plus engine-compartment circuits. Bulb data identifies H7 low beam, 9005/HB3 high beam, the Outback 9006/HB4 fog lamp, and sedan/wagon rear-lamp differences. Climate-control data identifies HFC134a refrigerant and a 12-month/9,300-mile air-filter interval where equipped.

Owner Procedures and Illustrated References

The Owner’s Manual provides procedures for CR2025 key-fob battery replacement and resynchronization, programming or deleting up to four remote codes, alarm/chirp and passive-arming settings, remote-start option functions, oil/filter and coolant service, air-cleaner and wiper replacement, bulb and fuse replacement, flat-tire handling, jump starting, overheating, towing, and manual rear-gate release. They are identified here without reproducing the working sequences.

Illustrated references include Sedan and Station Wagon SRS component-location views, three engine-compartment overviews, U.S./Canada combination-meter layouts, both fuse charts, the bulb chart, and vehicle-identification label locations. Electrical coverage is limited to controls, indicators, fuses, bulbs, and owner-level checks; there are no wiring diagrams or electrical schematics.

Important Service Cautions

Before repair work around the steering wheel or column, dashboard, center console, front seats, center pillars, roof-side areas, rear wheelhouses, or under the rear center seat, review the SRS section. Yellow SRS and pretensioner circuits must not be probed with electrical test equipment; tampering can cause accidental deployment or leave the system inoperative. A Subaru AWD vehicle must never be tested on a single two-wheel dynamometer because uncontrolled movement and serious transmission damage can result. On 5-speed automatic models, non-specified ATF can damage the transmission; Dexron III is described only as a temporary substitute for the 4-speed unit.

The 63-page restraint chapter covers the FMVSS 208 advanced frontal-airbag system, dual-stage inflators, passenger weight and seatbelt-tension sensing, pretensioners, LATCH and top-tether anchors, side and curtain airbags, monitored sensors/modules, warning-light behavior, service boundaries, and modification risks. It is safety and system-reference material, not 68 pages of airbag repair diagnostics.

For technicians, independent repair shops, and experienced DIY owners, this manual is most useful for confirming vehicle configuration, owner-service specifications, warning indicators, and safety limits before parts selection or deeper repair work.
