About the 2006 Cadillac STS

Your 2006 Cadillac STS is from the STS generation, which covers model years 2005–2011. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2006 model year.

Check the model year on your VIN: on a 2006 vehicle the 10th character of the 17-digit VIN is “6”. 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 20 years old, a 2006 vehicle is in the age range where wiring, rubber hoses, seals and corrosion repairs take most of the work, and where original factory information is hardest to find.

Same generation: 2005 Cadillac STS, 2007 Cadillac STS, 2008 Cadillac STS, 2009 Cadillac STS, 2010 Cadillac STS, 2011 Cadillac STS.

All Cadillac STS model years: 2005 · 2006 · 2007 · 2008 · 2009 · 2010 · 2011
