with Acura's ''SportShift sequential'' shift capability, activated by paddles mounted on the steering wheel for 2007-2009 models (additionally FWD was offered in some trims for 2010-2012 models). The paddles can be used in Drive (D) to make a gear change with the transmission returning to automatic mode as soon as the vehicle resumes a steady-cruise state. The Sport (S) setting has higher shift points and quicker downshifts, and using a paddle in “Sport” immediately puts the transmission in fully-manual mode. The four-cylinder engines in the first-generation RDX all use a timing chain, whereas the V6 installed in subsequent years (2013-2018) all use timing belts.

s, including dual front airbags, front side airbags, and dual-side curtain airbags. The front airbags use a dual-threshold, dual-stage technology that can adjust the timing and speed of each airbag deployment depending on the degree of impact and the driver's or front passenger's seat belt usage. If sensors deem the front passenger is too small (less than ), the front airbag is designed not to deploy. The front passenger's side airbag is also designed to shut off if a child or small-statured adult is leaning into the airbag's deployment path. In the event of a sufficient side impact or roll-over, the side curtain airbag deploys from above the door frames of the affected side, with coverage for both the front and rear occupants on that side, and stays inflated longer than if there were a collision. Front seats feature active head restraints and their seat belts are equipped with pre-tensioners and force limiters. In November 2006, the RDX was crash-tested by the U.S.
