LTZ (2018–2019 Premier), AN3 seats; two-tone, extra charge; the lists name it Cocoa/Pillion Brown Sauvage; the 2015 and 2016 Suburban guides and the 2018 and 2019 Suburban order guides print the code only with a footnote digit (H4X3, H4X4), so 2015, 2018 and 2019 rest on no citable page and are left out of the years, and 2016 and 2017 rest on the shared lists
