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.

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 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 HBC determines that it is dark based on the brightness of the surrounding area. At the same time, the HBC indicator light (green) in the instrument cluster illuminates.
The HBC determines that it is dark based on the brightness of the surrounding area.
When the vehicle speed is about 30 km/h (19 mph) or more, 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 HBC switches the headlights to low beams.
The low beams may not switch to high beams when cornering.
Operation of the HBC function can be disabled. Refer to Personalisation Features (Search).
Switching to low beams
Shift the lever to the low beam position.
The HBC indicator light (green) turns off.

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 system switches the headlights to the high beams after the ignition is switched ON and the headlight switch is in the position. The ALH indicator light (green) in the instrument cluster turns on simultaneously.
The ALH determine that it is nighttime based on the brightness of the surrounding area.
The system cancels operation when the headlight switch is turned to a position other than , the headlights are manually switched to low beams, or the high beams are flashed on and off.
The system can be changed so that the ALH do not operate.
Refer to Personalisation Features (Search).

The ALH indicator light (green) turns off and the is illuminated.
The LDWS notifies the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traffic lane using the Forward Sensing Camera (FSC) and if it determines that the vehicle may be deviating from its lane, it notifies the driver using the active driving display (vehicles with active driving display), and by flashing the LDWS warning light and activating the LDWS warning beep.
Use the LDWS when you drive the vehicle on roads with white or yellow lines.
Refer to Forward Sensing Camera (Search).
The warning light illuminates when the system has a malfunction.
Refer to Warning Lights (Search).
Do not use the LDWS under the following conditions:
The system may not operate adequately according to the actual driving conditions, resulting in an accident.
Driving on roads with tight curves.
Driving under bad weather conditions (rain, fog, and snow).
The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not designed to compensate for a driver’s lack of caution and if you rely too much on the LDWS it could lead to an accident. The driver is responsible for assuring lane changes and other manoeuvres. Always pay attention to the direction in which the vehicle is travelling and the vehicle’s surroundings.
Do not modify the suspension. If the vehicle height or the damping force of the suspensions is changed, the LDWS may not operate correctly.
If your vehicle deviates from its traffic lane, the LDWS operates (warning sound and indicator light). Steer the vehicle adequately to drive the vehicle to the centre of the lane.
When the direction indicator lever is operated for a lane change, the LDWS warning is automatically cancelled. The LDWS warning becomes operable when the direction indicator lever is returned and the system detects the white or yellow lines.
If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the vehicle moves close to a white or yellow line, the system determines that the driver is making a lane change and the LDWS warning is automatically cancelled.
The LDWS may not operate during the period immediately after the vehicle has deviated from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly within a short period of time.
The LDWS does not operate if it does not detect the white or yellow lines of the traffic lane.
Under the following conditions, the LDWS may not be able to detect white or yellow lines correctly and the LDWS may not operate correctly.
If an object placed on the instrument panel is reflected in the windscreen and picked up by the camera.
Heavy luggage is loaded in the luggage compartment or on the rear seat and the vehicle is inclined.
The tyre pressures are not adjusted to the specified pressure.
When the vehicle is driven on the entry and exit to or from the rest area or tollgate of a highway.
The white or yellow lines are less visible because of dirt or paint flaking.
The vehicle ahead is running near a white or yellow line and the line is less visible.
A white or yellow line is less visible because of bad weather (rain, fog, or snow).
The vehicle is driven on a temporary lane or section with a closed lane due to construction.
A misleading line is picked up on the road such as a temporary line for construction, or because of shade, lingering snow, or grooves filled with water.
The surrounding brightness suddenly changes such as when entering or exiting a tunnel.
The illumination of the headlights is weakened because of dirt or the optical axis is deviated.
The windscreen is dirty or foggy.
Back-light is reflecting from the road surface.
The road surface is wet and shiny after rain, or there are puddles on the road.
The shade of a guardrail parallel to a white or yellow line is on the road.
The width of a lane is excessively narrow or wide.
The road is excessively uneven.
The vehicle is shaken after hitting a road bump.
There are two or more adjacent white or yellow lines.
There are various road markings or lane markings of various shapes near an intersection.
The system goes on operation standby when the LDWS OFF 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.
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.
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 turn.
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.
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 30 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.
Press the LDWS OFF switch to cancel the LDWS. The LDWS OFF indicator light turns on.
If the system determines that there is the possibility of a lane departure, the LDWS warning beep activates and the LDWS warning light flashes. Operate the steering wheel appropriately and steer the vehicle to the centre of the lane.
For vehicles equipped with the active driving display, if there is the possibility of a lane departure, the system indicates the direction it determines that the vehicle is deviating in the active driving display.
Indication on display
If the LDWS warning sound is set to rumble*1, the sound will be heard from the vehicle speaker on the side which the system determined the vehicle may be deviating from its lane.
It may be difficult to hear the LDWS warning beep depending on the surrounding conditions such as outside noise.
The volume of the LDWS warning sound can be changed.
Refer to Personalisation Features (Search).
The type of warning sound (rumble*1/beep) on the LDWS can be changed.
Refer to Personalisation Features (Search).
A rumble strip is a series of grooves in the road pavement surface positioned at specific intervals, and when the vehicle passes over it a vibration and rumble sound is produced which alerts the driver that the vehicle is departing from the lane.
The rumble sound is a reproduction of the sound which occurs when a vehicle passes over a rumble strip.
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on both sides during lane changes by notifying the driver of the presence of vehicles approaching from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while travelling in the forward direction at a speed of 30 km/h (19 mph) or faster and notifies the driver by turning on the BSM warning indicator light and displaying the vehicle detection screen (vehicles with active driving display).
If the direction indicator lever is operated to signal a turn in the direction in which the BSM warning indicator light is illuminated while the approaching vehicle is detected, the BSM notifies the driver of possible danger by turning on the BSM warning indicator light, and by activating the warning sound and the warning screen indicator display (vehicles with active driving display).
The detection area on this system covers the driving lanes on both sides of the vehicle and from the rear part of the front doors to about 50 m (164 ft) behind the vehicle.
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a lane change. Due to certain limitations with the operation of this system, the BSM warning indicator light, the warning sound and the warning screen indicator display may not activate or they might be delayed even though a vehicle is in an adjacent driving lane. Always make it your responsibility as a driver to check the rear.
The BSM will operate when all of the following conditions are met:
The ignition is switched ON.
The BSM OFF indicator light in the instrument cluster is turned off.
The vehicle speed is about 30 km/h (19 mph) or faster.
The BSM will not operate under the following circumstances.
The vehicle speed falls below about 25 km/h (15 mph) even though the BSM OFF switch indicator light is turned off.
The shift lever (manual transaxle)/selector lever (automatic transaxle) is shifted to reverse (R) and the vehicle is reversing.
The turning radius is small (making a sharp turn, turning at intersections).
In the following cases, the BSM OFF indicator light turns on and operation of the system is stopped. If the BSM OFF indicator light remains illuminated, have the vehicle inspected at an Authorised Mazda Repairer as soon as possible.
Some problem with the system including the BSM warning indicator lights is detected.
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). Remove any snow, ice or mud on the rear bumper.
Driving on snow-covered roads for long periods.
The temperature near the radar sensors (rear) 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.
A vehicle is in the detection area at the rear in an adjacent driving lane but it does not approach. The BSM determines the condition based on radar detection data.
A vehicle is travelling alongside your vehicle at nearly the same speed for an extended period of time.
Vehicles approaching in the opposite direction.
A vehicle in an adjacent driving lane is attempting to pass your vehicle.
A vehicle is in an adjacent lane on a road with extremely wide driving lanes. The detection area of the radar sensors (rear) is set at the road width of expressways.
In the following case, the flashing of the BSM warning indicator light, and the activation of the warning sound and the warning screen indicator display may not occur or they may be delayed.
A vehicle makes a lane change from a driving lane two lanes over to an adjacent lane.
Driving on steep slopes.
Crossing the summit of a hill or mountain pass.
When there is a difference in the height between your driving lane and the adjacent lane.
Directly after the BSM system becomes operable by changing the setting.
If the road width is extremely narrow, vehicles two lanes over may be detected. The detection area of the radar sensors (rear) is set according to the road width of expressways.
The BSM warning indicator light may turn on and the vehicle detection screen may be displayed in the display in reaction to stationary objects (guardrails, tunnels, sidewalls, and parked vehicles) on the road or the roadside.
A BSM warning indicator light may flash or the warning beep and the warning screen indicator display may be activated several times when making a turn at a city intersection.
Turn off the BSM while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radar’s radio waves will be blocked causing the system to not operate normally.
In the following cases, it may be difficult to view the illumination/flashing of the BSM warning indicator lights equipped on the door mirrors.
Snow or ice is adhering to the door mirrors.
The front door glass is fogged or covered in snow, frost or dirt.
The system switches to the Rear Cross Traffic Alert function when the shift lever (manual transaxle) or the selector lever (automatic transaxle) is shifted to the reverse (R) position.
Refer to Rear Cross Traffic Alert (RCTA) (Search).
The BSM or Rear Cross Traffic Alert (RCTA) system notifies the driver of the presence of vehicles in adjacent lanes or at the rear of the vehicle using the BSM warning indicator light, the warning sound and the display indicator (vehicles with active driving display) (BSM) while the systems are operational.
BSM warning indicator lights
The BSM warning indicator lights are equipped on the left and right door mirrors. The warning indicator lights turn on when a vehicle approaching from the rear in an adjacent lane is detected.
When the ignition is switched ON, the warning indicator light turns on momentarily and then turns off after a few seconds.
Forward driving (BSM operation)
The BSM detects vehicles approaching from the rear and turns on the BSM warning indicator lights equipped on the door mirrors according to the conditions. Additionally, while a BSM warning indicator light is illuminated, if the direction indicator lever is operated to signal a turn in the direction in which the BSM warning indicator light is illuminated, the BSM warning indicator light flashes.
Reverse driving (Rear Cross Traffic Alert (RCTA) system operation)
The Rear Cross Traffic Alert (RCTA) system detects vehicles approaching from the left and right of your vehicle and flashes the BSM warning indicator lights.
Function for cancelling illumination dimmer
If the BSM warning indicator lights turn on when the position lights are turned on, the brightness of the BSM warning indicator lights is dimmed.
If the BSM warning indicator lights are difficult to see due to glare from surrounding brightness when travelling on snow-covered roads or under foggy conditions, press the dimmer cancellation button to cancel the dimmer and increase the brightness of BSM warning indicator lights when they turn on.
Refer to Instrument Panel Illumination (Search).
Display indicator (Vehicles with active driving display)
The detected approaching vehicle and warning are displayed in the active driving display when the vehicle is moving forward (BSM operational).
The detected direction is displayed with a detection indicator (white) when an approaching vehicle is detected. In addition, if the direction indicator lever is operated to signal a lane change while the vehicle is detected, the display changes the colour (amber) of the warning indicator.
BSM warning beep
The BSM warning beep is activated simultaneously with the flashing of a BSM warning indicator light.
The BSM and Rear Cross Traffic Alert (RCTA) systems are turned off and the BSM OFF indicator light in the instrument cluster turns on.
Vehicles with BSM OFF switch
When the BSM OFF switch is pressed, the BSM and Rear Cross Traffic Alert (RCTA) systems are turned off and the BSM OFF indicator light in the instrument cluster turns on.
If the switch is pressed again, the BSM and Rear Cross Traffic Alert (RCTA) systems become operable and the BSM OFF indicator light turns off.
When the ignition is switched OFF, the system status before it was turned off is maintained. For example, if the ignition is switched OFF while the BSM and Rear Cross Traffic Alert (RCTA) systems are operable, the BSM and Rear Cross Traffic Alert (RCTA) systems remain operable the next time the ignition is switched ON.
Vehicles without BSM OFF switch
The BSM system can be set to inoperable.
Refer to Personalisation Features (Search).
When the BSM is set to inoperable, the BSM and Rear Cross Traffic Alert (RCTA) systems are turned off and the BSM OFF indicator light in the instrument cluster turns on.
When the ignition is switched OFF, the system status before it was turned off is maintained. For example, if the ignition is switched OFF while the BSM and Rear Cross Traffic Alert (RCTA) systems are operational, the BSM and Rear Cross Traffic Alert (RCTA) systems remain operational the next time the ignition is switched ON.
The TSR helps prevent the driver from overlooking traffic signs, and provides support for safer driving by displaying traffic signs on the active driving display which are recognised by the Forward Sensing Camera (FSC) or recorded in the navigation system while the vehicle is driven.
The TSR displays the speed limit (including auxiliary signs) and do not enter signs.
If the vehicle speed exceeds the speed limit sign indicated in the active driving display while the vehicle is driven, the system notifies the driver using the indication in the active driving display and a warning sound.
The TSR is not supported in some countries or regions. For information concerning the supported countries or regions, consult an expert repairer, we recommend an Authorised Mazda Repairer.
The TSR operates only if the navigation system SD card (Mazda genuine) is inserted in the SD card slot. Consult an expert repairer, we recommend an Authorised Mazda Repairer for details.
Always check the traffic signs visually while driving.
The TSR helps prevent the driver from overlooking traffic signs and provides support for safer driving.

The SCBS R is a system which is designed to reduce damage in the event of a collision by operating the brake control (SCBS brake) when the system’s ultrasonic sensors detect an obstruction at the rear of the vehicle while driving at a speed of about 2 to 8 km/h (2 to 4 mph) and the system determines that a collision is unavoidable.
Do not rely completely on the SCBS R system:
The SCBS R 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.
To assure the correct operation of the SCBS R, heed the following cautions.
Do not apply a sticker to an ultrasonic sensor (rear) (including transparent stickers). Otherwise, the ultrasonic sensor (rear) may not be able to detect vehicles or obstructions which could result in an accident.
Do not disassemble an ultrasonic sensor (rear).
If cracks or damage caused by flying gravel or debris is visible around an ultrasonic sensor (rear), stop using the SCBS R system immediately and have your vehicle inspected by an expert repairer, we recommend an Authorised Mazda Repairer. If the vehicle continues to be driven with cracks or scratch marks left around an ultrasonic sensor, the system may operate unnecessarily and cause an unexpected accident.
Refer to Stopping the Smart City Brake Support [Reverse] (SCBS R) System Operation (Search).
Consult an expert repairer, we recommend an Authorised Mazda Repairer for rear bumper replacement.
Do not modify the suspension:
If the vehicle height or inclination is changed, the SCBS R system may not operate correctly because it cannot detect obstructions correctly.
Do not apply a strong force to an ultrasonic sensor (rear):
When washing the vehicle, do not spray highly pressurised water against an ultrasonic sensor (rear), or rub it strongly. In addition, do not hit the rear bumper forcefully when loading and unloading cargo Otherwise, the sensors may not detect obstructions correctly which could cause the SCBS R system to not operate normally, or it could operate unnecessarily.
When driving off-road in areas where there is grass or foliage, it is recommended that the SCBS R system be turned off.
Always use tyres of the specified size and the same manufacturer, brand, and tread pattern on all 4 wheels. In addition, do not use tyres with significantly different wear patterns on the same vehicle. Otherwise, the SCBS R system may not operate normally.
If ice or snow is stuck on the ultrasonic sensors (rear) they may not be able to detect obstructions correctly depending on the conditions. In such cases, the system may not be able to perform controls correctly. Always drive carefully and pay attention to the rear of the vehicle.
The vehicle posture changes depending on the accelerator pedal, brake pedal and steering wheel operations, which could make it difficult for the system to recognise an obstruction, or it could facilitate unnecessary detection. In such cases, the SCBS R may or may not operate.
The SCBS R system will operate under the following conditions.
The engine is running.
The change lever (manual transaxle vehicle) or the selector lever (automatic transaxle vehicle) is in the R (reverse) position.
The vehicle speed is between about 2 to 8 km/h (2 to 4 mph).
