About the 2023 Kia K5

Your 2023 Kia K5 is from the K5 generation, which covers model years 2021–2026. 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 2023 model year.

Check the model year on your VIN: on a 2023 vehicle the 10th character of the 17-digit VIN is “P”. 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 3 years old, a 2023 vehicle mostly needs scheduled maintenance, software and battery checks, and correct procedures for the newer electronic systems (ADAS sensors, calibrations and module programming).

Same generation: 2021 Kia K5, 2022 Kia K5, 2024 Kia K5, 2025 Kia K5, 2026 Kia K5.

All Kia K5 model years: 2021 · 2022 · 2023 · 2024 · 2025 · 2026
