What to look for
- Check the infotainment menus/settings related to this feature.
- Look for physical buttons, labels or interior/exterior cues.
- Compare with OEM documentation for your model year (trim names are not reliable).
Common confusion
- Aftermarket retrofits can look similar but won’t match factory build coding.
- Some features are bundled with other options; the factory code is the proof.
Best way to confirm: verify your exact car options build data via VIN and match it to SA 3AZ.
