Safety

The R-Class received a Good overall score — the highest rating possible — in the Insurance Institute for Highway Safety's frontal-offset and side-impact crash tests. It hadn't yet undergone IIHS' new roof-strength test as of publication.

Standard safety features include side-impact airbags for the first and second rows, side curtain airbags for all three rows, antilock brakes, an electronic stability system, active head restraints for the front seats, and Pre-Safe. In the event of a likely collision, as determined by braking and stability system sensors, Pre-Safe cinches the seat belts and adjusts the position of the front seats for optimal occupant protection. A blind spot warning system is optional.
