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 supports safer driving by helping the driver to recognise potential hazards and avert accidents.

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).
High Beam Control System (HBC)
Adaptive LED Headlights (ALH)
Driver Attention Alert (DAA)
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.
Refer to Forward Sensing Camera (FSC) (Search).
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.
Refer to Radar Sensor (Front) (Search).
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) (Search).
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.
Refer to Ultrasonic Sensors (Rear) (Search).
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.
Refer to Warning/Indicator Lights (Search).
Headlights do not blind drivers approaching in the opposite direction no matter what side of the road you must drive your vehicle (left-hand or right-hand traffic). Therefore, it is not necessary to adjust the optical axis of the headlights when switching temporarily to driving on the opposite side of the road (left-hand or right-hand traffic).
The Adaptive Front Lighting System (AFS) function can be switched to operable/inoperable using the personalisation function.
Refer to Personalisation Features (Search).
The High Beam Control System (HBC) determines the conditions in front of the vehicle using the Forward Sensing Camera (FSC) while driving in darkness to automatically switch the headlights between high and low beams.
Refer to Warning/Indicator Lights (Search).
While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are switched to high beams when there are no vehicles ahead or approaching in the opposite direction.
The system switches the headlights to low beams when one of the following occurs:
The system detects a vehicle or the headlights/lights of a vehicle approaching in the opposite direction.
The vehicle is driven on roads lined with streetlamps or on roads in well-lit cities and towns.
The vehicle is driven at less than about 20 km/h (12 mph).
The warning light turns on when the system has a malfunction.
Refer to Warning Lights (Search).
Do not adjust the vehicle height, modify the headlight units, or remove the camera, otherwise the system will not operate normally.
Do not rely excessively on the High Beam Control System (HBC) and drive the vehicle while paying sufficient attention to safety. Switch the headlights between the high beams and low beams manually if necessary.
The timing in which the system switches the headlights changes under the following conditions. If the system does not switch the headlights appropriately, manually switch between high and low beams according to the visibility as well as road and traffic conditions.
When there are sources of light in the area such as street lamps, illuminated signboards, and traffic signals.
When there are reflective objects in the surrounding area such as reflective plates and signs.
When visibility is reduced under rain, snow and foggy conditions.
When driving on roads with sharp turn or hilly terrain.
When the headlights/rear lamps of vehicles in front of you or in the opposite lane are dim or not illuminated.
When there is sufficient darkness such as at dawn or dusk.
When the luggage compartment is loaded with heavy objects or the rear passenger seats are occupied.
When visibility is reduced due to a vehicle in front of you spraying water from its tyres onto your windscreen.
The High Beam Control System (HBC) operates to switch the headlights automatically between high and low beams after the ignition is switched ON and the headlight switch is in the AUTO and high beam position.
The High Beam Control System (HBC) determines that it is dark based on the brightness of the surrounding area. At the same time, the High Beam Control System (HBC) indicator light (green) in the instrument cluster illuminates.
When the vehicle speed is about 30 km/h (19 mph) or more, the headlights automatically switch to high beams when there are no vehicles ahead or approaching in the opposite direction.
When the vehicle speed is less than about 20 km/h (12 mph), the High Beam Control System (HBC) switches the headlights to low beams.
The low beams may not switch to high beams when cornering.
Operation of the High Beam Control System (HBC) function can be disabled. Refer to Personalisation Features (Search).
The Advanced Smart City Brake Support (Advanced SCBS) alerts the driver of a possible collision using the display and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle ahead or pedestrian and determines that a collision with the object is unavoidable while the vehicle is driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph) if the object is a vehicle ahead and about 10 to 80 km/h (6.2 to 50 mph) if the object is a pedestrian. In addition, the system reduces damage in the event of a collision by operating the brake control (SCBS brake) when the system determines that a collision is unavoidable. In addition, when the driver depresses the brake pedal, the brakes are applied firmly and quickly to assist. (Brake Assist (Advanced SCBS brake assist))
Do not rely completely on the Advanced Smart City Brake Support (Advanced SCBS) system:
The Advanced Smart City Brake Support (Advanced SCBS) system is only designed to reduce damage in the event of a collision. Over reliance on the system leading to the accelerator pedal or brake pedal being mistakenly operated could result in an accident.
