EBD allocates braking force according to load: with a full complement of passengers or when heavily laden with luggage, EBD boosts brake force to the rear wheels to maintain Mazda3's short stopping distance.

Intelligent Auto Light System assures better visibility for easier driving. The system uses both forward- and upward-facing sensors to monitor ambient light to automatically switch on the lights when necessary – such as entering a tunnel.

Mazda Advanced Impact Distribution and Absorption System built around a unique triple-H structure resists deformation and efficiently disperses impact energy away from the cabin.

Front airbags deploy to maximize passenger protection and minimize the risk of airbag-inflicted injuries.

Front seatbelts feature a pretensioner to instantaneously tighten the belt in a collision and hold the occupant firmly in place. After pretensioner operation, a load limiter loosens the seatbelt in a controlled manner to prevent excessive pressure on the wearer’s chest.

Crashable brake pedal features a structure to retract the pedal away from the driver's foot in a frontal collision to lower the risk of pedal-inflicted foot and leg injuries. Mazda3's steering column collapses horizontally to minimize impact on the driver's head and chest.
