Backup grid lines

[Zoni]

2021 Tahoe premier has only one grid line for backup assistance. Daughters 2022 Tahoe Z71 has two. Am I missing something?

On the camera screen, the grid line button selects between 1 line for lining up a trailer tongue and the grid area. Press the button. See “Surroubd Vision” in the owners manual.
