Blind Spot Monitoring (BSM) (Some Models)
Blind Spot Monitoring (BSM)
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.
BSM operation
The BSM detects vehicles approaching from the rear while traveling in the forward direction at a speed of 10 km/h (6.3 mph) or faster and notifies the driver by turning on the BSM warning indicator light and displaying the vehicle detection screen.
If the turn signal 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 flashing on the BSM warning indicator light, and by activating the warning sound and the warning screen indicator 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.

-
Your vehicle
-
Detection areas
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 i-ACTIVSENSE warning indication/warning light in the instrument cluster is turned off.

-
The shift lever (manual transmission)/selector lever (automatic transmission) 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 i-ACTIVSENSE warning indication/warning light turns on and operation of the system is stopped. If the i-ACTIVSENSE warning indication/warning light remains illuminated, have the vehicle inspected at an Authorized Mazda Dealer 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 rear side radar sensor on the vehicle has occurred.

-
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 rear side radar sensor 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 rear side radar sensor 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.
-
Objects such as guardrails and concrete walls running alongside the vehicle.
-
Places where the width between guardrails or walls on each side of the vehicle narrows.

-
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.

Refer to Rear Side Radar Sensor (Search).
-
The system switches to the Rear Cross Traffic Alert (RCTA) function when the shift lever (manual transmission) or the selector lever (automatic transmission) is shifted to the reverse (R) position.
Refer to Rear Cross Traffic Alert (RCTA) (Search).
Canceling Operation of Blind Spot Monitoring (BSM)
The BSM system can be set to inoperable.

If the ignition is switched OFF while you have canceled the system using the i-ACTIVSENSE OFF switch, the system is automatically enabled the next time the ignition is switched ON. However, if the system is canceled using the personalization features, the system is not automatically enabled.
Vehicle Ahead Close Proximity Warning
When the system determines that the distance between your vehicle and a vehicle ahead is close, the i-ACTIVSENSE status symbol (warning/risk avoidance support system) changes from green to amber and the warning indication is displayed on the multi-information display. While checking the safety of the surrounding area, depress the brake pedal while keeping a safe distance from the vehicle ahead.

Driver Attention Alert (DAA)
The DAA is a system which detects driver fatigue and decreased attentiveness, and encourages the driver to take a rest.
When the vehicle is driven inside traffic lane lines at about 65 to 140 km/h (41 to 86 mph), the DAA estimates the amount of accumulated fatigue and decreased attentiveness of the driver based on the information from the Forward Sensing Camera (FSC) and other vehicle information, and encourages the driver to take a rest using an indication on the multi-information display and a warning sound.
Use the DAA on expressways or highways.
Refer to Forward Sensing Camera (FSC) (Search).

Do not rely completely on DAA and always drive carefully:
The DAA detects driver fatigue and decreased attentiveness and encourages the driver to take a rest, however, it is not designed to prevent the vehicle from straying. If you rely too much on the DAA it could lead to an accident. Drive carefully and operate the steering wheel appropriately.
In addition, the system may not be able to detect driver fatigue and decreased attentiveness correctly depending on the traffic and driving conditions. The driver must take sufficient rest in order to drive safely.
-

-
The vehicle is jolted or swayed continuously by strong winds or rough roads.
-
The vehicle is driven aggressively.
-
When making frequent lane changes.
-
The vehicle is making a curve.
-
-
The DAA detects driver fatigue and decreased attentiveness based on the driving data when the vehicle is driven at about 65 to 140 km/h (41 to 86 mph) for about 20 minutes. The driving data will be reset under the following conditions.
-
The vehicle is stopped for 15 minutes or longer.
-
The vehicle is driven at less than about 65 km/h (41 mph) for about 30 minutes.
-
The ignition is switched off.

Rear side radar sensor
The rear side radar sensors are installed inside the rear bumper, one on each side.
Always keep the surface of the rear bumper near the rear side radar sensors clean so that they operate normally. Also, do not apply items such as stickers.
Refer to Exterior Care (Search).
If the rear bumper receives a severe impact, the system may no longer operate normally. Stop the system immediately and have the vehicle inspected at an Authorized Mazda Dealer.
-
The detection ability of the rear side radar sensor has limitations. In the following cases, the detection ability may lower and the system may not operate normally.
-
The rear bumper near the rear side radar sensor has become deformed.
-
Snow, ice or mud adheres to the rear side radar sensor on the rear bumper.
-
Under bad weather conditions such as rain, snow and fog.
-
-
Under the following conditions, the rear side radar sensor cannot detect target objects or it may be difficult to detect them.
-
Small motorcycles, bicycles, pedestrians, animals, shopping carts, and stationary objects on a road or a road side.
-
Vehicle shapes which do not reflect radar waves well such as empty trailers with a low vehicle height and sports cars.
-
-
Vehicles are shipped with the direction of the rear side radar sensor adjusted for each vehicle to a loaded vehicle condition so that the rear side radar sensor detect approaching vehicles correctly. If the direction of the rear side radar sensor has deviated for some reason, have the vehicle inspected at an Authorized Mazda Dealer.
-
For repairs or replacement of the rear side radar sensor, or bumper repairs, paintwork, and replacement near the radar sensors, consult an Authorized Mazda Dealer.
-
The radar sensors are regulated by the relevant radio wave laws of the country in which the vehicle is driven. If the vehicle is driven abroad, authorization from the country in which the vehicle is driven may be required.
