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.

Camera and Sensors

Forward Sensing Camera (FSC)

The Forward Sensing Camera (FSC) detects lane indications and recognizes headlights, taillights and city lights during nighttime driving. In addition, it also detects the vehicle ahead, pedestrians, or obstructions. The following systems also use the Forward Sensing Camera (FSC).

High Beam Control system (HBC)
Lane Departure Warning System (LDWS)
Traffic Sign Recognition System (TSR)
Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)
Advanced Smart City Brake Support (Advanced SCBS)
Smart City Brake Support (SCBS)
Smart Brake Support (SBS)

The Forward Sensing Camera (FSC) is installed at the top of the windshield near the rearview mirror.

Refer to Forward Sensing Camera (FSC).

Radar sensor (front)

The radar sensor (front) functions by detecting the radio waves reflected off a vehicle ahead sent from the radar sensor. The following systems also use the radar sensor (front).

Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)
Distance Recognition Support System (DRSS)
Smart Brake Support (SBS)

The radar sensor (front) is mounted behind the radiator grille. Refer to Radar Sensor (Front).

Radar sensors (rear)

The radar sensors (rear) function by detecting the radio waves reflected off a vehicle approaching from the rear or an obstruction sent from the radar sensors. The following systems also use the radar sensors (rear).

Blind Spot Monitoring (BSM)
Rear Cross Traffic Alert (RCTA)

The radar sensors (rear) are installed inside the rear bumper, one each on the left and right sides.

Refer to Radar Sensors (Rear).

i-ACTIVSENSE

Adaptive Front Lighting System (AFS)(Some models)

The adaptive front lighting system (AFS) automatically adjusts the headlight beams to the left or right in conjunction with the operation of the steering wheel after the headlights have been turned on and the vehicle speed is about 2 km/h (2 mph) or higher...

Mazda CX-3 (2015-2025) Owner's Manual: Lane Departure Warning System (LDWS)(Some models)

The LDWS notifies the driver that the vehicle may be deviating from its lane. The system detects the white or yellow lines on the traffic lane using the Forward Sensing Camera (FSC) and if it determines that the vehicle may be deviating from its lane, it notifies the driver using the active driving display (vehicles with active driving display), and by flashing the LDWS warning light and activating the LDWS warning beep...
