The 2012 Mercedes-Benz R-Class has a solid set of safety features, and in addition to some good safety ratings it has M-B's decades-earned reputation for safety.
Eight airbags are included in all 2012 Mercedes-Benz R-Class models, along with the Pre-Safe safety system and front active headrests. There's also a blind-spot system that alerts with a triangle in the rearview mirror, as well as a chime, when you use the turn signal and another vehicle is alongside.
In Insurance Institute for Highway Safety (IIHS), the R-Class has achieved top 'good' results for frontal, side, and rear impact--although it still hasn't been tested in the agency's new roof strength area. The federal government also hasn't yet put the R-Class through its battery of tests, which were revised last year.
