2008 Cadillac SLS Service and Repair Manual

For China, Cadillac stretched the STS into the SLS, and the 2008 car is that Shanghai GM-built, China-market luxury sedan with roughly 100 mm of extra wheelbase for chauffeur-driven rear passengers. Its second model year carried the launch range of engines: a 2.8-liter DOHC V6, a 3.6-liter DOHC V6 and the 4.6-liter Northstar V8, all driving the rear wheels. Shanghai GM also began shipping the SLS to Middle East markets around this time. The long body and China-specific equipment separate it from the US STS, so this factory service and repair manual gives SLS-specific procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules.
