Smart Brake Support

The SBS is a system designed to detect target objects using sensors and cameras equipped on the vehicle, and to reduce damage in the event of a collision by operating the brake control if there is the possibility of your vehicle colliding with a target object. One part of the SBS functions when you are driving forward and the other part functions when you are driving in reverse.

• Refer to Forward drive detection.
• Refer to Reverse drive detection.

Forward drive detection
When you are driving forward, the following functions of the Smart Brake Support (SBS) operate.

• Forward detection function

WARNING

Do not rely completely on the SBS:
The SBS is only designed to reduce damage in the event of a collision. The system may not operate normally depending on the target object, weather conditions, or traffic conditions. Over reliance on the system leading to the accelerator pedal or brake pedal being mistakenly operated could result in an accident.

CAUTION

In the following cases, turn the SBS off to prevent a misoperation.

• The vehicle is being towed or towing another vehicle.
• The vehicle is driven on rough roads such as in areas where there is grass and foliage or off-road.
•  

NOTE
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.

Forward detection function
The forward detection function is designed to reduce damage in the event of a collision with target objects at the front. The forward detection function detects target objects (vehicles ahead, pedestrians, and bicycles) using the front radar sensor and the Forward Sensing Camera (FSC). If there is a possibility of your vehicle colliding with a target object at the front, you are notified of possible danger by a warning sound and a warning indication on the display. Furthermore, if the possibility of a collision increases, the 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.

(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.

Operation conditions
The forward detection function operates when all of the following conditions are met.

•  The ignition is switched ON.
• The SBS is on.
• (Object is vehicle ahead)
  The vehicle speed is about 4 km/h (3 mph) or higher.
• (Object is a pedestrian or bicycle) The vehicle speed is between about 10 and 80 km/h (6.3 to 49 mph).
• The DSC does not operate.

NOTE

• When any of the following conditions is met, the forward detection function may not operate.
• If there is the possibility of hitting only a part of a vehicle or obstruction ahead.
• You are driving your vehicle at the same speed as the vehicle ahead.
• When the driver deliberately performs driving operations N(accelerator operation, steering wheel operation).
• The accelerator pedal is depressed abruptly.
• The brake pedal is depressed.
• The steering wheel is being operated.
•  (Automatic transmission)
  The selector lever is being shifted.
• The turn signal lever is being operated.
• Warnings and messages, such as a dirty windshield, related to the Forward Sensing Camera (FSC) or front radar sensor are being displayed on the multi-information display.
• When any of the following conditions is met, the forward detection function may operate.
• There is an object in the road at the entrance to a curve (including guardrails and snow banks).
• Passing an approaching vehicle while rounding a curve.
• When crossing a narrow bridge, going under a low overhang, or passing through a narrow gate, a car washing machine, or tunnel.
• When passing through a toll gate.
• When entering an underground parking area.
• There is a metal object, bump, or a protruding object on the road.
• If you suddenly come close to a vehicle ahead.
• An animal, wall, or standing tree is detected.
• While the system is operating, the driver is notified by the multi-information display and the active driving display.
• If a malfunction is detected or the system temporarily stops the function due to dirt on the sensors or cameras, the i-ACTIVSENSE warning light turns on and a message is displayed on the multi-information display.
• (Manual transmission)
  On a manual transmission vehicle, the engine stops if the clutch pedal is not depressed when the vehicle is stopped by the SBS brake operation.
• If the vehicle is stopped by the SBS brake operation and the brake pedal is not depressed, the SBS brake is automatically released after about 2 seconds.

Collision warning
If there is the possibility of your vehicle colliding with a target object at the front, the warning sound is activated continuously and a warning is 4-170 *Some models displayed on the multi-information display and the active driving display. Multi-information display.

1. “BRAKE!” message is displayed Active driving display*
   
2. “BRAKE!” message is displayed N

NOTE

• During brake control and brake assist operation, the collision warning sound is activated intermittently.
• The operation distance and volume of the collision warning can be changed.
  Refer to the Settings section in the Mazda Connect Owner’s Manual.

Reverse drive detection
When you are driving in reverse, the following functions of the Smart Brake Support (SBS) operate.

• Rearward detection function
• Rear crossing

WARNING
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 apply stickers (including transparent stickers) to the areas around the rear side radar sensors and the rear ultrasonic sensors. Otherwise, a rear side radar sensor and a rear ultrasonic sensor may not be able to detect vehicles and obstructions correctly which could result in an accident.
• Do not disassemble the rear side radar sensors and rear ultrasonic sensors.
• If you recognize scratches around the rear side radar sensors and rear ultrasonic sensors, stop using the SBS immediately and always have the vehicle inspected by an Authorized Mazda Dealer.
  Consult an Authorized Mazda Dealer for rear bumper removal/installation.

Do not modify the suspension:
If the vehicle height or inclination is changed, the SBS may not operate correctly because it cannot detect obstructions correctly.

Do not hit the rear side radar sensors and rear ultrasonic sensors forcefully:
When washing the vehicle, do not spray highly pressurized water against the rear side radar sensors and the rear ultrasonic sensors, or rub them strongly. In addition, do not hit the rear bumper forcefully when loading and unloading cargo. Otherwise, the system will be unable to detect obstructions correctly and the SBS may not operate normally.

CAUTION

• In the following cases, 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. Refer to Stopping the Smart Brake Support (SBS) System Operation on page 4-176.
• Always use tires for all wheels that are of the specified size, and the same manufacture, brand, and tread pattern. 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.

NOTE
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.

Rearward detection function
The rearward detection function is designed to reduce damage in the event of a collision with a target object when reversing.

The rearward detection function detects obstructions using the rear ultrasonic sensors. In addition, if there is the possibility of your vehicle colliding with a target object at the rear while you are driving in reverse, you are notified of possible danger by a warning sound and a warning indication on the display. Furthermore, if the possibility of a collision increases, brake control is performed to reduce damage in the event of a collision.

WARNING

Always check the surrounding area visually when reversing the vehicle:
The operation of the rearward detection function has certain limitations. Therefore, the function might not operate or it might be delayed even if there is a target object at the rear of your vehicle. Always make it your responsibility as a driver to check the rear.
