There are eight
airbags on board the 2011 Mercedes-Benz R-Class, along with the Pre-Safe safety
system and front active headrests. Newly available is 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.
the R-Class has been revised for 2011, it will need to be retested; the 2010
model achieved top "good" results for frontal, side, and rear
protection from the IIHS, though it wasn't tested by the federal government.
