I had a medium sized doe run in front of the vehicle while on the highway. I had the adaptive cruise control set to 62 MPH with lane keeping assist and all other safety features enabled. When the deer ran out out in front of the vehicle the emergency breaking did not engage, nor did it flash the warning or make the chime. It caused major damage to the front center and drivers side of the vehicle. The air bags did not deploy. However, after the collision, the airbag light on the dash illuminated and stayed on. The airbag light has never came on before other than the illumination test when first starting the car. Also, the Hazzard lights did not com on automatically. The collision had enough impact to send the several hundred pound deer over 100' down the road. The only safety feature that partly worked was the retracting seat belts. I say partly worked because only the lap portion tightened. There was no tightening of the shoulder portion, which is now locked in place.
