From what I found in the Order Guide, there is a new feature called “Side Bicyclist Alert” - this feature appears to replace “Side Blond Zone Alert” completely which no longer appears as a feature in the order guide. The Side Bicyclist Alert is listed as only being available on the Automatic Transmissions.
I’ve been trying to read up on functionality of it compared to old traditional side blind zone systems to see why they would drop the feature from manuals. The only hypothesis I can come up with is that some of the functionality is dependent on the car being in park (to detect bicyclists before you open your door). Manuals don’t have a park gear.
Still, that seems dumb to me as you could simply track the parking brake. I know not everyone who drives stick necessarily uses the brake all the time which is a major reason why you don’t get remote start. This is a complete head scratcher though - at minimum, they could just disable the bicycles alert feature while keeping the traditional side blind zone alert.
Maybe someone from GM on here could better explain.
