The RDX's standard headlights help the model earn a Top Safety Pick+ designation from the IIHS. Oddly, the top-of-the-line Advance package is only rated Acceptable (to the other trims' Good rating) because the IIHS found the model's set-up caused more glare for oncoming drivers. In either case the RDX's standard collision mitigation braking system avoided collisions at 12 and 25 mph. The NHTSA gives the RDX a five-star overall score. The RDX comes standard with the Acura Watch suite of safety- and driver-assist features. In addition to adaptive cruise control, it includes lane-departure warning with corrective steering assist, blind-spot monitoring, forward collision warning, and collision mitigation braking. A surround-view camera system and rear cross-traffic alert are optionally available.
