Spark — M400 (2016–2022)

2017–2018 Confirmed

2LT; high-back front buckets (AV5); footnote-digit-only (rule 11(d)): the 2017 guide's color and trim page (p.22) prints the code with the raised footnote mark 2 (includes Blue seat insert), and the 2018 guide's (GM Authority PDF copy, p.30) prints HH62; no page prints the bare code, so the row carries no factory citation

This page aggregates every documented appearance of HH6 in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
