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

Your 2018 Colorado is from the second-generation Colorado, built for model years 2015–2022. Years of the same generation share most procedures; equipment and electrical details still change from year to year, so the manual follows your VIN.
