i-ACTIVSENSE
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 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 (vehicles with active driving display).
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 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 10 km/h (6.3 mph) or faster.
-
-
The BSM will not operate under the following circumstances.
-
The vehicle speed falls below about 10 km/h (6.3 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 warning indication/warning light turns on and operation of the system is stopped. If the BSM 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 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 traveling 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 radar sensors (rear) of the BSM may be regulated under the radio wave related laws of the country where the vehicle is driven. The sensors in this system are approved for use in the U.S.A. (including territories), Canada, and Mexico. If a vehicle with a BSM is driven in a country other than the U.S.A., Canada, or Mexico, the system has to be turned off using the BSM OFF switch.
-
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).
Smart Brake Support (SBS) (Some Models)
The SBS system alerts the driver of a possible collision using a display and warning sound if the radar sensor (front) and the Forward Sensing Camera (FSC) determine that there is the possibility of a collision with a vehicle ahead while the vehicle is being driven at about 15 km/h or faster (10 mph or faster). Furthermore, if the radar sensor (front) and the Forward Sensing Camera (FSC) 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 are applied firmly and quickly to assist. (Brake Assist (SBS brake assist))
Do not rely completely on the SBS system and always drive carefully:
The 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.
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.
-
The SBS system operates when all of the following conditions are met:
-
The ignition is switched ON.
-
The 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 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 turn signal is being used.
-
When the vehicle ahead is not equipped with taillights or the taillights are turned off.
-
When warnings and messages, such as a dirty windshield, related to the Forward Sensing Camera (FSC) are being displayed in the center 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 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.
