About the 2011 Cadillac STS
Model year 2011 is part of the STS generation (2005–2011). It is the last model year of this generation and includes the running changes made during production, which is why a manual for the exact year matters.
Check the model year on your VIN: on a 2011 vehicle the 10th character of the 17-digit VIN is “B”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 15 years old, a 2011 vehicle often needs work on the cooling system, timing components, suspension bushings, motor mounts and corroded electrical connectors, all jobs where the exact factory procedure and torque values save time.
Same generation: 2005 Cadillac STS, 2006 Cadillac STS, 2007 Cadillac STS, 2008 Cadillac STS, 2009 Cadillac STS, 2010 Cadillac STS.
