Not the owner's manual

Many people search for the 2023 Sierra owner's manual and need more than it gives. The difference:

• Owner's manual: controls, warning lights, maintenance schedule, fluid types
• Factory repair manual: removal and installation steps, torque specs, diagnostic trouble codes, wiring diagrams and component locations

The 2023 Sierra belongs to the T1XX Sierra generation, model years 2019–2026. Years of the same generation share most procedures; equipment and electrical details still change from year to year, so the manual follows your VIN.
