2 Chrysler Group achieves safety through a three part, holistic safety approach 1. Education – Safety Programs designed to educate and raise awareness of high-risk behavior 2. Active Safety – Features designed to mitigate or reduce collision severity prior to an impact 3. Passive Safety – Features designed to protect the occupant after an impact Chrysler Group Safety Overview Back Back
