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.

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).
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 Sensor (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).
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 illuminates or flashes when the system has a malfunction.
Refer to Warning/Indicator 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 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 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 30 km/h (19 mph) or higher, 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 Rear Cross Traffic Alert (RCTA) system is designed to assist the driver in checking the area to the rear of the vehicle on both sides while the vehicle is reversing by alerting the driver to the presence of vehicles approaching the rear of the vehicle.
The Rear Cross Traffic Alert (RCTA) system detects vehicles approaching from the left and right sides of the vehicle while the vehicle is being reversed out of a parking space, and notifies the driver of possible danger using the Blind Spot Monitoring (BSM) warning lights and the warning buzzer.
Rear Cross Traffic Alert (RCTA) operation
The Rear Cross Traffic Alert (RCTA) system operates when the selector lever is shifted to the reverse (R) position.
If there is the possibility of a collision with an approaching vehicle, the Blind Spot Monitoring (BSM) warning light flashes and the warning beep is activated simultaneously.
(With rearview monitor)
The Rear Cross Traffic Alert (RCTA) warning indication in the rearview monitor also synchronizes with the Blind Spot Monitoring (BSM) warning light on the door mirrors.
Always check the surrounding area visually before actually putting the vehicle in reverse:
The system is only designed to assist you in checking for vehicles at the rear when putting the vehicle in reverse. Due to certain limitations with the operation of this system, the Blind Spot Monitoring (BSM) warning light may not flash or it might be delayed even though a vehicle is behind your vehicle. Always make it your responsibility as a driver to check the rear.
In the following cases, the Blind Spot Monitoring (BSM) OFF indication/indicator light turns on and operation of the system is stopped. If the Blind Spot Monitoring (BSM) OFF indication/indicator light remains illuminated, have the vehicle inspected at an Authorised Mazda Dealer as soon as possible.
Some problem with the system including the Blind Spot Monitoring (BSM) warning lights has occurred.
A large deviation in the installation position of a radar sensor (rear) on the vehicle has occurred.
There is a large accumulation of snow or ice on the rear bumper near a radar sensor (rear).
Driving on snow-covered roads for long periods.
The temperature near the radar sensors becomes extremely hot due to driving for long periods on slopes during the summer.
The battery voltage has decreased.
Under the following conditions, the radar sensors (rear) cannot detect target objects or it may be difficult to detect them.
The vehicle speed when reversing is about 12 km/h (7 mph) or faster.
The radar sensor (rear) detection area is obstructed by a nearby wall or parked vehicle. Reverse the vehicle to a position where the radar sensor detection area is no longer obstructed.)
A vehicle is approaching directly from the rear of your vehicle.
The vehicle is parked on a slant.
Directly after pressing the Blind Spot Monitoring (BSM) switch and the system becomes operable.
In the following cases, it may be difficult to view the illumination/flashing of the Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors.
Snow or ice adheres to the door mirrors.
The front door glass is fogged or covered in snow, frost or dirt.
Turn off the Rear Cross Traffic Alert (RCTA) system while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will be blocked causing the system to not operate normally.
