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: how to take parts out and put them back, the torque for every bolt, fault codes and complete wiring diagrams

Your 2023 Ascent is from the Ascent generation, built for model years 2019–2026. Most procedures are shared with the other years of this generation, but options, software and wiring changed along the way, which is why the manual is built for your VIN.

Engine options

• 2,4 liter turbo, CVT, AWD.

Your manual is built for your version only: the VIN tells us the exact engine and transmission.
