To Operate the System
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.
-
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).
Adaptive LED Headlights (ALH) (Some Models)
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 (19 mph), the beams switch to the low beams.
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.
To Operate the System
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).
Blind Spot Monitoring (BSM) (Some Models)
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 instrument cluster (Type A/B) and 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 instrument cluster (Type A/B) and 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 R position 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 expert repairer (we recommend 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 2 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 2 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).
Cancelling Operation of Blind Spot Monitoring (BSM)
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 system notifies the driver that it provided steering wheel operation assistance on the multi-information display and the active driving display.
Multi-information display (Basic display)
Multi-information display (i-ACTIVSENSE display)
Active driving display
When the driver operates the steering wheel while the steering wheel operation assist is operating, the steering wheel operation assistance is cancelled.
Smart City Brake Support [Forward] (SCBS F) (Some Models)
The SCBS F system alerts the driver of a possible collision using an indication in the display and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle ahead and determines that a collision with a vehicle ahead is unavoidable while the vehicle is being driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system reduces damage in the event of a collision by operating the brake control (Smart City Brake Support (SCBS) brake) when the system determines that a collision is unavoidable while the vehicle is being driven at a vehicle speed of about 4 to 30 km/h (2 to 18 mph). It may also be possible to avoid a collision if the relative speed between your vehicle and the vehicle in front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the brake pedal while the system is in the operation range at about 4 to 30 km/h (2 to 18 mph), the brakes are applied firmly and quickly to assist. (Brake Assist (Smart City Brake Support (SCBS) brake assist))
Do not rely completely on the SCBS F system:
-
The SCBS F 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.
-
The SCBS F is a system which operates in response to a vehicle ahead. The system may not be able to detect or react to 2-wheeled vehicles or pedestrians.
In the following cases, turn the system off to prevent a mis-operation:
-
The vehicle is being towed or when towing another vehicle.
-
The vehicle is on a chassis roller.
-
When driving on rough roads such as in areas of dense grass or off-road.
