Mazda 3 Owners Manual: i-ACTIVSENSE

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.

Driver awareness support systems

Nighttime visibility

• Adaptive Front Lighting System (AFS)
• High Beam Control System (HBC)

Left/right side and rear side detection

• Lane Departure Warning System (LDWS)
• Blind Spot Monitoring (BSM) System

Forward obstruction warning

• Forward Obstruction Warning (FOW)

Rear obstruction detection when leaving a parking space

Rear Cross Traffic Alert (RCTA)

Driver support system

Inter-vehicle distance

• Mazda Radar Cruise Control (MRCC)

Pre-Crash Safety Technology

Pre-crash safety technology is designed to assist the driver in averting collisions or reduce their severity in situations where they cannot be avoided.

Collision damage reduction in low vehicle speed range

Forward driving

• Smart City Brake Support (SCBS)

Camera and Sensors

Forward sensing camera (FSC)

The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while traveling at night and detects traffic lanes. The following systems also use the Forward Sensing Camera (FSC).

• High Beam Control system (HBC)
• Lane Departure Warning System (LDWS)

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

Refer to Forward Sensing Camera (FSC) on .

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 (MRCC)
• Forward Obstruction Warning (FOW)

The radar sensor (front) is mounted behind the radiator grille.

Refer to Radar Sensor (Front) on .

Laser sensor (front)

The laser sensor (front) emits a near-infrared laser beam and receives the beam reflected off the reflective surface of a vehicle in front, and the detected beam is then used for measurement. The following systems also use the laser sensor (front).

• Smart City Brake Support (SCBS)

The laser sensor (front) is installed at the top of the windshield near the rearview mirror.

Refer to Laser Sensor (Front) on .

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) System
• Rear Cross Traffic Alert (RCTA)

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