Smart Brake Support (SBS)
Smart Brake Support (SBS) (Some Models)
SBS is a system designed to avoid collisions and reduce damage in the event of a collision by controlling the brakes. Sensors and camera equipped on the vehicle detect objects, and operate brake control if there is a possibility of your vehicle colliding with the object.
One part of the SBS functions when you are driving forward and the other part functions when you are driving in reverse.
Forward drive detection
Forward detection function (Some Models)
The forward detection function is designed to assist the driver in avoiding collisions with objects (vehicles ahead, pedestrians, bicycles, and motorcycles) at the front and to reduce damage in the event of a collision.
If there is a possibility of your vehicle colliding with a target object at the front, you are notified of possible danger by a screen display and a warning sound. Furthermore, if the possibility of a collision increases, brake control is performed to avoid collision and 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.
Reverse drive detection
Reverse drive detection has the following 2 functions.
Rearward detection function (Some Models)
The rearward detection function is designed to assist the driver in avoiding collisions with objects at the rear (obstructions) and to reduce damage in the event of a collision.
If there is a possibility of your vehicle colliding with a target object at the rear, you are notified of possible danger by a screen display and a warning sound. Furthermore, if the possibility of a collision increases, brake control is performed to avoid collision and reduce damage in the event of a collision.
Rear Crossing (Some Models)
The Rear Crossing is designed to avoid collision and reduce damage in the event of a collision with a vehicle approaching from the rear sides.
If there is a possibility of your vehicle colliding with a vehicle approaching from the rear sides, you are notified of possible danger by a screen display and a warning sound. Furthermore, if the possibility of a collision increases, brake control is performed to avoid collision and reduce damage in the event of a collision.
Warnings and Cautions for Using the Smart Brake Support (SBS)
Do not rely completely on the SBS.
The SBS 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.
Heed the following cautions so that the SBS can operate normally.
-
Do not modify the suspensions.
-
Handle the Forward Sensing Camera (FSC) appropriately. Otherwise, the Forward Sensing Camera (FSC) may not be able to detect target objects, which could result in an accident.
Refer to Forward Sensing Camera (FSC) (Search).
-
Handle the radar sensors appropriately. Otherwise, the radar sensors may not be able to detect target objects, which could result in an accident.
Refer to Radar Sensors (Search).
-
Handle the ultrasonic sensors appropriately. Otherwise, the ultrasonic sensors may not be able to detect target objects, which could result in an accident.
Refer to Ultrasonic Sensors (Search).
Always check the surrounding area visually.
The operation of the SBS has certain limitations. Always confirm the safety around the vehicle visually when driving.
-
If any of the following conditions is met, turn the SBS off to prevent a mis-operation.
-
A trailer is pulled or an accessory such as a bicycle carrier is installed to the rear of the vehicle.
-
The vehicle is driven on rough roads such as in areas where there is grass and foliage or off-road.
-
-
Always use tires of the specified size and the same manufacturer, brand, and tread pattern on all 4 wheels. In addition, do not use tires with significantly different wear patterns on the same vehicle. If such improper tires are used, the SBS may not operate normally.
How to Use the Smart Brake Support (SBS)
During the SBS brake control, the brake pedal may move rearward or become stiff. The brakes are operating, but continue to depress the brake pedal.
When the forward detection function operates (Some Models)
The forward detection function operates when all of the following conditions are met.
-
(If an object is a vehicle ahead)
-
The vehicle speed is about 4 km/h (3 mph) or faster.
-
-
(If an object is a bicycle/pedestrian)
-
The vehicle speed is about 10 km/h to 80 km/h (6.3 mph to 49 mph).
-
-
The DSC does not operate.
-
The system determines that there is a possibility of a collision with an object ahead.
When the forward detection function operates, the driver is notified of the danger by the screen display and warning sound. Furthermore, if the possibility of a collision increases, brake control is performed.

If any of the following conditions is met, the forward detection function may not operate normally.
-
When there is the possibility of a partial contact with a target object.
-
The driver deliberately performs driving operations (accelerator pedal operation, steering wheel operation, selector lever operation, and turn signal lever operation).
-
If any of the following conditions is met, the forward detection function may operate.
-
An animal or object on the road is detected.
-
Passing an approaching vehicle while rounding a curve.
-
Vehicle is passing through a narrow gate or a gate with a low ceiling.
-
There is a metal object, bump, or a protruding object on the road.
-
-
(Vehicles with Driver Monitoring (DM))
If the system determines that the driver is not paying attention to the road, it activates the collision warning earlier than normal.
-
If the forward detection function performs brake control and the vehicle is stopped, the system will continue to hold the brakes for a brief time unless there is an operation performed by the driver.
-
The operation distance and volume of the collision warning can be changed.
Refer to the Settings section in the Mazda Connect Owner's Manual.
When the rearward detection function operates (Some Models)
The rearward detection function operates when all of the following conditions are met.
-
The vehicle speed is about 2 km/h to 15 km/h (2 mph to 9.3 mph).
-
The system determines that there is a possibility of collision with an object at the rear.
When the rearward detection function operates, the screen display and warning sound notify the driver of the danger. Furthermore, if the possibility of a collision increases, brake control is performed.

If any of the following conditions is met, the rearward detection function may operate.
-
There is a hanging curtain.
-
Vehicle is passing through a narrow gate or a gate with a low ceiling.
-

-
The vehicle speed is about 15 km/h (9.3 mph) or slower.
-
