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.
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 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 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 ALH are a system which uses the Forward Sensing Camera (FSC) to determine the situation of a vehicle ahead or a vehicle approaching in the opposite direction while driving at night to automatically switch the illumination range of the headlights, the illuminated area, or the illumination brightness.
Refer to Forward Sensing Camera (FSC) (Search).
The ALH are controlled between high and low beams as follows to assure the driver’s visibility without dazzling a vehicle ahead or a vehicle approaching in the opposite direction.
Glare-Free High Beam
This feature dims only the high-beam light shone on the vehicle ahead.
The high beams will dim while driving at a speed of about 40 km/h (25 mph) or faster. When the vehicle speed is less than about 30 km/h (18 mph), the beams switch to the low beams.
The headlight high-beam indicator light turns on while the high beams are on.
Wide-Range Low Beam
This feature extends the illumination range of the light cast by the low beams while driving at a speed less than about 40 km/h (25 mph).
Highway Mode
This feature shifts the illumination angle of the light cast by the headlights upward while driving on highways.
The distance in which the ALH can detect objects varies depending on the surrounding conditions.
Do not modify the suspensions or headlight units, or remove the camera. Otherwise, the ALH may not operate normally.
Do not rely excessively on the ALH and drive the vehicle while paying sufficient attention to safety. Switch the headlights between the high beams and low beams manually if necessary.
Under the following conditions, the ALH may not operate normally. Manually switch between the high and low beams according to the visibility, and the road and traffic conditions.
When there are other 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 curves or undulations.
When the headlights/rear lamps of vehicles ahead or in the opposite lane are dim or not illuminated.
When there is insufficient 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 ahead spraying water from its tyres onto your windscreen.
The ASL is a function to prevent the vehicle from being driven at a vehicle speed faster than a set speed. The vehicle speed is controlled to kept it below the set speed even if the accelerator pedal is depressed.
The ASL can be set between 30 km/h (20 mph) and 200 km/h (125 mph). The vehicle speed may exceed the set speed when the vehicle is driven on a down slope, however, the system notifies the driver by flashing the display and operating a warning sound.
Always turn off the system when changing drivers:
If the driver is changed and the new driver is unaware of the ASL function, the vehicle may not accelerate when the driver depresses the accelerator pedal, leading to an accident.
The system consists of the ASL display and the speed limiter switch on the steering wheel.
The setting status of the ASL is displayed in the active driving display (Type A instrument cluster*1) or the display in the instrument cluster (Type B instrument cluster*1).
To determine which instrument cluster is equipped on your Mazda, Refer to Meters and Gauges (Search).

The 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 (Advanced 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 SCBS system:
The 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.
The Advanced SCBS system operates in response to a vehicle ahead or a pedestrian. The system does not operate in response to obstructions such as a wall, 2-wheeled vehicles, or animals.
In the following cases, turn the system off to prevent a mis-operation:
The vehicle is being towed or when towing another vehicle.
The vehicle is on a chassis roller.
When driving on rough roads such as in areas of dense grass or off-road.
Refer to Stopping the Advanced Smart City Brake Support (Advanced SCBS) System Operation (Search) on how to turn off the Advanced SCBS system.
