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) determines the conditions ahead of the vehicle while travelling 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)
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).
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)
Smart Brake Support (SBS)
The laser sensor (front) is installed at the top of the windscreen near the rearview mirror.
Refer to Laser 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) System
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).
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 are equipped which 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 (18 mph), 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 flashes 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 curves 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.
Your vehicle is equipped with a Forward Sensing Camera (FSC). The Forward Sensing Camera (FSC) is positioned near the rearview mirror and used by the following systems.
High Beam Control System (HBC)
Lane Departure Warning System (LDWS)
Smart Brake Support (SBS)
The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while travelling at night and detects traffic lanes. The distance in which the Forward Sensing Camera (FSC) can detect objects varies depending on the surrounding conditions.
Do not apply accessories, stickers or film to the windscreen near the Forward Sensing Camera (FSC).
If the area in front of the Forward Sensing Camera (FSC) lens is obstructed, it will cause the system to not operate correctly. Consequently, each system may not operate normally which could lead to an unexpected accident.
Do not disassemble or modify the Forward Sensing Camera (FSC).
Disassembly or modification of the Forward Sensing Camera (FSC) will cause a malfunction or mistaken operation. Consequently, each system may not operate normally which could lead to an unexpected accident.
Heed the following cautions to assure the correct operation of the Forward Sensing Camera (FSC).
The direction of the Forward Sensing Camera (FSC) has been finely adjusted, therefore do not change the installation position or remove the Forward Sensing Camera (FSC).
Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get dirty.
Do not remove the Forward Sensing Camera (FSC) cover.
Do not place objects on the instrument panel which reflect light.
Always keep the windscreen glass around the camera clean by removing dirt or fogging. Use the windscreen defroster to remove fogging on the windscreen.
