Forward Sensing Camera (FSC) The Forward Sensing Camera (FSC) detects lane indications and recognises headlights, tail lights 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).

• Adaptive LED Headlights (ALH)
• Driver Attention Alert (DAA)
• Lane Departure Warning System (LDWS)
• Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS)
• Traffic Sign Recognition System (TSR)
• Advanced Smart City Brake Support (Advanced SCBS)
• Smart City Brake Support [Forward] (SCBS F)
• Smart Brake Support (SBS)

The Forward Sensing Camera (FSC) is installed at the top of the windscreen 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 (MRCC)
• 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. Ultrasonic sensors (rear) The ultrasonic sensors (rear) function by detecting the ultrasonic waves reflected off obstructions at the rear sent from the ultrasonic sensors. The following systems also use the ultrasonic sensors (rear).

• Smart City Brake Support [Reverse] (SCBS R)

The ultrasonic sensors (rear) are mounted in the rear bumper.
