FAQQuestions about the STS manual
Which STS years does this manual cover?
Every year from 2005 to 2011 — 7 separate manuals, one per model year. Pick your year in the selector; the manual you receive is matched to that exact year, engine and trim.
Is this the OEM Cadillac STS manual or an aftermarket guide?
The OEM version. It carries the procedures, specifications, torque values and wiring diagrams Cadillac published for the STS, organized by system — not a condensed aftermarket summary.
Does it include STS wiring diagrams?
Yes. Full wiring diagrams are part of every STS manual, alongside repair procedures, specifications and diagnostic information.
Does the manual cover STS recalls?
6 recalls are on federal record across the 2005–2011 STS, listed by year below. The manual carries the manufacturer's diagnostic and repair procedures behind the systems involved; the recall repairs themselves are performed free by Cadillac dealers.
Why do some STS years cost more?
Every STS year is $29.99.
Is this a subscription?
No. One payment, and the manual is yours to keep — unlike per-vehicle subscriptions that renew every year.
How do I get the manual after purchase?
