Mazda 6 Owners Manual: Smart Brake Support (SBS) (Some models)

The Smart Brake Support (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))

WARNING

Do not rely completely on the Smart Brake Support (SBS) system and always drive carefully:

The Smart Brake Support (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.

CAUTION

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.

NOTE

• The Smart Brake Support (SBS) system operates when all of the following conditions are met:
  • The ignition is switched ON.
  • The Smart Brake Support (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 Smart Brake Support (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 multi-information 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 Smart Brake Support (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.
  • When passing under a low gate or through a tunnel or narrow gate.
  • When entering an underground parking area.
  • Metal objects, bumps, or protruding objects on the road.
  • If you suddenly come close to a vehicle ahead.
  • When driving in areas where there is high grass or forage.
  • Two-wheeled vehicles such as motorbikes or bicycles.
  • Pedestrians or non-metallic objects such as standing trees.
