• A real person checks every order and the VIN before the manual is built

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: diagnosis by trouble code, step-by-step repairs, tightening torques, wiring diagrams and connector views

The 2005 STS belongs to the STS generation, model years 2005–2011. It is the first model year of this generation, so wiring, body and many procedures differ from the model before it.

Typical repairs for a 2005 STS

• Rust repair and body panels
• Fuel pump, filter and lines
• Brake lines, hoses and master cylinder
• Ignition components and idle problems
• Suspension bushings and steering play
