Mazda CX-3: i-ACTIVSENSE / i-ACTIVSENSE (Some models)

Mazda CX-3 (2015-2025) Owner's Manual / When Driving / i-ACTIVSENSE / i-ACTIVSENSE (Some models)

i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support systems which make use of a Forward Sensing Camera (FSC) and radar sensors. These systems consist of active safety and pre-crash safety systems. These systems are designed to assist the driver in safer driving by reducing the load on the driver and helping to avert collisions or reduce their severity. However, because each system has its limitations, always drive carefully and do not rely solely on the systems.

Active Safety Technology

Active Safety Technology supports safer driving by helping the driver to recognize potential hazards and avert accidents.
