Mazda CX-9 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.

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-keep Assist System (LAS) & 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.

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.

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.

Front camera/side cameras/rear view camera

The front camera, side cameras, and rear camera shoot images of the area surrounding the vehicle. The 360º View Monitor uses each camera.

Cameras are installed to the front bumper, door mirrors, and liftgate.

Adaptive Front Lighting System (AFS)

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.

A system malfunction or operation conditions are indicated by a warning.

NOTE The Adaptive Front Lighting System (AFS) function can be switched to operable/inoperable using the personalization function.


High Beam Control System (HBC)
