i-ACTIVSENSE
i-ACTIVSENSE (Some Models)
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.

-
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).

-
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).
Adaptive Front Lighting System (AFS) (Some Models)
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).
To Operate the System
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 (18 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).
Manual Switching
Switching to low beams
Shift the lever to the low beam position.
The High Beam Control System (HBC) indicator light (Green) turns off.

-
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.
Cancelling The System

Rear Cross Traffic Alert (RCTA) (Some Models)
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 shift lever (manual transaxle) or the selector lever (automatic transaxle) 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.
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 indicator light turns on and operation of the system is stopped. If the Blind Spot Monitoring (BSM) OFF indicator light remains illuminated, have the vehicle inspected at an Authorised Mazda Dealer as soon as possible.
