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 system goes on operation standby when the LDWS switch is pressed and the LDWS OFF indicator light in the instrument cluster turns off. For vehicles equipped with the active driving display, the driving lane (border lines) is indicated in the display.
Indication on display
Drive the vehicle in the centre of the driving lane while the LDWS OFF indicator light is turned off. The system becomes operational when all of the following conditions are met.
The vehicle is driven in the centre of the driving lane with the white or yellow lines on the left and right sides, or on either side.
The vehicle speed is 70 km/h (44 mph) or faster.
The vehicle is driven on a straight road or road with gentle curves.
For vehicles equipped with the active driving display, the driving lane is indicated in the display.
Indication on display
The LDWS does not operate in the following cases:
The system cannot detect white or yellow lines.
The vehicle speed is less than 65 km/h (40 mph).
The vehicle is making a sharp curve.
The vehicle is making a curve at an inadequate speed.
The LDWS does not operate until the system detects a white or yellow line on either the left or right.
When the system detects a white or yellow line on one side only, the system will activate the warning only when the vehicle deviates on the side where the white or yellow line is being detected.
The distance and warning sensitivity (likelihood of a warning) which the system uses to determine the possibility of a lane departure can be changed.
Refer to Personalisation Features (Search).
Auto cancel
In the following cases, the LDWS cancels automatically and the LDWS warning light in the instrument cluster turns on.
The temperature inside the camera is high or low.
The windscreen around the camera is foggy.
The windscreen around the camera is blocked by an obstruction, causing poor forward visibility.
For vehicles equipped with the active driving display, the lane (border lines) is indicated in the display. The LDWS is enabled automatically when the operation conditions are met, and the LDWS warning light turns off.
Auto cancel warning
When the following operations are performed, the LDWS determines that the driver intends to make a lane change and the LDWS warning is cancelled automatically. The LDWS is enabled automatically after the driver performs the operation.
The steering wheel is operated abruptly.
The brake pedal is depressed abruptly.
The accelerator pedal is depressed abruptly.
The direction indicator lever is operated (after the direction indicator lever is returned, the LDWS may not operate for about 3 seconds which is the period of time required to make a lane correction).
After about 60 seconds have elapsed with the direction indicator lever left operating, the LDWS warning may operate if the vehicle is close to a white or yellow line.
Smart Brake Support (SBS) is a system which alerts the driver of a possible collision using an indicator and warning sound in the instrument cluster while the vehicle is being driven at about 15 km/h or faster (10 mph or faster) and the system's radar sensor (front) determines that your vehicle may hit a vehicle ahead. Furthermore, if the radar sensor (front) determines that a collision is unavoidable, the automatic brake control is performed to reduce damage in the event of a collision.
In addition, when the driver depresses the brake pedal, the brakes operate more quickly to assist the driver (vehicles with brake fluid pre-fill).
Do not rely completely on the Smart Brake Support (SBS) system and always drive carefully:
The Smart Brake Support (SBS) is designed to reduce damage in the event of a collision, not avoid an accident. The ability to detect an obstruction is limited depending on the obstruction, weather conditions, or traffic conditions. Therefore, if the accelerator pedal or brake pedal is mistakenly operated it could result in an accident. Always verify the safety of the surrounding area and depress the brake pedal or accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
If the vehicle is towed or you are towing something, switch the Smart Brake Support (SBS) system off to prevent a mistaken operation.
The Smart Brake Support (SBS) system operates when all of the following conditions are met:
The ignition is switched ON.
The Smart Brake Support (SBS) system is on.
The vehicle speed is about 15 km/h or faster (10 mph or faster).
The relative speed between your vehicle and the vehicle ahead is about 15 km/h or faster (10 mph or faster).
The Dynamic Stability Control (DSC) is not operating.
The Smart Brake Support (SBS) system may not operate under the following conditions:
If the vehicle is accelerated rapidly and it comes close to a vehicle ahead.
The vehicle is driven at the same speed as the vehicle ahead.
The accelerator pedal is depressed.
The brake pedal is depressed.
The steering wheel is being operated.
The selector lever is being operated.
The direction indicator is being used.
When the vehicle ahead is not equipped with tail lights or the tail lights are turned off.
When warnings and messages, such as a dirty windscreen, related to the Forward Sensing Camera (FSC)/laser sensor (front) are being displayed in the centre display.
Although the objects which activate the system are four-wheeled vehicles, the radar sensor (front) could detect the following objects, determine them to be an obstruction, and operate the Smart Brake Support (SBS) system.
Objects on the road at the entrance to a curve (including guardrails and snow banks).
A vehicle appears in the opposite lane while cornering or rounding a curve.
When crossing a narrow bridge.
When passing under a low gate or through a tunnel or narrow gate.
When entering an underground parking area.
Metal objects, bumps, or protruding objects on the road.
If you suddenly come close to a vehicle ahead.
When driving in areas where there is high grass or forage.
Two-wheeled vehicles such as motorbikes or bicycles.
Pedestrians or non-metallic objects such as standing trees.
When the system operates, the user is notified by the flashing Smart Brake Support (SBS) indicator light (red) and the active driving display.
The Smart Brake Support (SBS) warning light (amber) turns on when the system has a malfunction. Refer to Warning/Indicator Lights (Search).
If the Smart Brake Support (SBS) is operating, the indicator light (red) flashes.
If there is the possibility of a collision with a vehicle ahead, the beep sounds continuously and a warning is indicated in the active driving display.
The Smart Brake Support (SBS) system can be temporarily deactivated.
Refer to Personalisation Features (Search).
When the Smart Brake Support (SBS) system is turned off, the Smart Brake Support (SBS) OFF indicator light turns on.
When the engine is restarted, the system becomes operational.
If the Smart Brake Support (SBS) system operation is turned off, the Smart City Brake Support (SCBS) system operation is turned off simultaneously.
