What this manual has that the owner's manual does not

The owner's manual stops where the repair starts. The factory repair manual picks up from there:

• Owner's manual: controls, warning lights, maintenance schedule, fluid types
• Factory repair manual: removal and installation steps, torque specs, diagnostic trouble codes, wiring diagrams and component locations

Model year 2003 is part of the second-generation Impreza (GD/GG) (2002–2007). Most procedures are shared with the other years of this generation, but options, software and wiring changed along the way, which is why the manual is built for your VIN.

Engines available for the 2003 Impreza

• 2,0 liter engine, CVT transmission, AWD
• 2,0 liter engine, 5MT transmission, AWD

The manual is made for the version in your VIN, so you don't have to work out your engine code.

• Suspension bushings and steering play
• Cooling system overhaul
