Adaptive brake lights: Effective warning of rear-end collisions

If your vehicle supports the adaptive brake light feature, make sure to enable both the flashing brake light and hazard flasher. The adaptive
brake lights only function with panic braking from speeds over 30mph (the hazards only activate when stopped from speeds over 45mph).

Shertex, what is your build date? My June 2005 E320's rear SAM does not have the adaptive brake light option to enable.
