Thanks again rav. I was looking for that! I looked on line but the list is long... 412 pages

It looks like mine does not have that option. Tho I do have a panic button.
I have recently acquired a 2017 Silverado, pretty base model. v8, 4x4, manual trans case. My question is, do all 2017's have alarms? My owners manual says it does but I cannot seem to set or activate it.
Thanks for any thoughts.
