The C30 includes Volvo's IDIS (Intelligent Driver Information System), which delays certain functions, such as a phone call when the driver is engaged in a more complicated maneuver (heavy braking, turning, and so on). A rear obstacle detection system is also available as an option. Other options not otherwise available in this class are a blind-spot alert system (Volvo's BLIS) and a lane-departure warning system.
Although the federal government hasn't crash-tested the C30, its safety looks to be one of the best, among small hatchbacks. It's an Insurance Institute for Highway Safety (IIHS) Top Safety Pick, earning a top 'good' rating in every test category, including the new roof strength test.
