Documented applications

ATS — Alpha (2013–2019)

2019 Single-source

3.6L models in the sedan guide; the 2015 coupe guide and the 2018 coupe and sedan guides print the code with a footnote digit attached (HEY6, HEY4, HEY5) and name it elsewhere only in a cross-reference note, so 2015 and 2018 are left out; 2019 from GM Authority's 2019 ATS interior colors page, which does not credit GM

Escalade — K2XX (2015–2020)

2015–2017 Factory-verified

2015: Luxury, Premium; extra charge; the lists read leather, level 4, Jet Black/Vecchio; GM Authority 2016 trim table
