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.

• If any of the following conditions is met, the forward detection function may not operate normally.

  • The Forward Sensing Camera (FSC) cannot detect target objects.

    Refer to Forward Sensing Camera (FSC) (Search).

  • The front radar sensor cannot detect target objects.

    Refer to Radar Sensors (Search).

• 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.

• If any of the following conditions is met, the Turn-Across Traffic may not operate normally.

  • The Forward Sensing Camera (FSC) cannot detect target objects.

    Refer to Forward Sensing Camera (FSC) (Search).

  • The front radar sensor cannot detect target objects.

    Refer to Radar Sensors (Search).

  • The vehicle approaching in the opposite direction is a two-wheeled vehicle or a bicycle.

  • All of or only a part of a vehicle approaching in the opposite direction is hidden and it cannot be recognized.

  • The speed of the on-coming vehicle is too slow or too fast.

  • Turning at a large intersection with two lanes or more on one side.

  • The accelerator pedal or brake pedal is being operated.

  • The steering wheel is being operated in the straight-ahead position.

• The Turn-Across Traffic may not operate depending on the country where the vehicle is driven.

• If any of the following conditions is met, the Turn-Across Traffic may operate.

  • The steering wheel is turned towards the on-coming traffic lane with a vehicle approaching in the opposite direction.

  • Turning right after or right before an oncoming vehicle passes.

  • The direction of movement of a vehicle approaching in the opposite direction cannot be predicted due to sudden right/left turning or sudden deceleration.

• The brakes are released by the brake control of the Turn-Across Traffic as soon as the danger of a collision passes.

• Front Crossing may not operate normally if any of the following conditions is met.

  • The front side radar sensors cannot detect target objects.

    Refer to Radar Sensors (Search).

  • The accelerator pedal or brake pedal is being operated.

  • The steering wheel is being operated.

  • The turn signal lever is being operated.

• The Front Crossing brake force may differ depending on the operation conditions.

• If Front Crossing performs brake control and the vehicle is stopped, the vehicle is held stopped until the estimated passing time of the target vehicle has elapsed.

• If the Forward Sensing Camera (FSC) cannot detect objects, the intersection accident avoidance assist function may not operate normally.

  Refer to Forward Sensing Camera (FSC) (Search).

• If the intersection accident avoidance assist 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.

• Head-on collision mitigation may not operate normally when any of the following conditions is met.

  • The Forward Sensing Camera (FSC) cannot detect target objects.

    Refer to Forward Sensing Camera (FSC) (Search).

  • The front radar sensor cannot detect target objects.

    Refer to Radar Sensors (Search).

  • The vehicle approaching in the opposite direction is a two-wheeled vehicle or a bicycle.

  • The vehicle in the opposite direction is stopped.

  • The speed of the vehicle approaching in the opposite direction is too slow or too fast.

  • There is the possibility of partial contact with the target object.

  • The driver deliberately performs driving operations (accelerator pedal operation, steering wheel operation, selector lever operation, and turn signal lever operation).

  • The vehicle lane makes a curve.

  • The vehicle lane width is outside the range of about 3 m to 3.6 m (118 in to 142 in).

• Even if there is no eventual collision, head-on collision mitigation may operate if the vehicle approaching in the opposite direction comes very close to the front of your vehicle.

• After head-on collision mitigation operates, the brakes may be released before the collision depending on the conditions.

• If any of the following conditions is met, the rearward detection function may not operate normally.

  • The rear ultrasonic sensors cannot detect an object.

    Refer to Ultrasonic Sensors (Search).

  • The rear camera cannot detect an object.

    Refer to Cameras (Search).

• 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.

  • There is a metal object, bump, or a protruding object on the road.

• If the rearward 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.

• If any of the following conditions is met, the Rear Crossing may not operate normally.

  • The rear side radar sensors cannot detect an object.

    Refer to Radar Sensors (Search).

  • A vehicle is approaching directly from the rear of your vehicle.

  • A vehicle is approaching at an angle from the rear of your vehicle.

  • A vehicle is approaching from a direction at an acute angle.

• If any of the following conditions is met, the Rear Crossing may operate.

  • There is a hanging curtain.

  • Vehicle is passing through a narrow gate or a gate with a low ceiling.

• If the Rear Crossing 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.
