Hyundai doesn't believe consumers should have to pay a premium for safety, so a long list of safety features is included as standard equipment on all 2012 Accent models. A total of six airbags protect occupants in the event of a collision, including two front impact airbags, two front seat-mounted side impact airbags, and curtain side-impact airbags for front and rear passengers. Hyundai Accent's new standard front-seat active head restraints help prevent whiplash by automatically reducing the space between a front occupant's head and the head restraint during certain rear collisions and are highly recommended by safety organizations such as the Insurance Institute for Highway Safety (IIHS). Active front head restraints are not available on Fiesta, Yaris, Aveo or Mazda2.

The Hyundai Accent's underlying structure is engineered to protect occupants using a Collision Load Dispersion mechanism and the rear doors have internal beams. The vehicle's structure distributes the force of an impact in three ways to minimize floor deformation and maintain the integrity of the cabin.

Electronic Stability Control (ESC) and Traction Control work together to help deliver confident handling in all conditions. Vehicle Stability Management (VSM) integrates control of the ESC and motor-driven power steering (MDPS) to provide handling assistance in slippery conditions or in sudden cornering scenarios. The system can deliver up to eight Newton-meters of counter-steering effort when required to assist the driver in maintaining control of the vehicle.

A key safety element for any vehicle is its braking system. Hyundai Accent is the only car in the subcompact segment to offer four wheel disc brakes as standard equipment. An Anti-lock Braking System (ABS) featuring Electronic Brake Force Distribution (EBD) and Brake Assist (BA) is also included. EBD examines the effect of vehicle load on weight distribution and apportions the braking force between front and rear axles to maximize stopping ability. In the event of a panic stop, BA ensures that maximum braking force is applied.
