SCBS (Smart City Brake Support)

Rear-end collisions are the most common type of accident, and approximately 60% of these occur at relatively low speeds of 30km/h or less.

Smart City Brake Support (SCBS) helps the driver avoid frontal collisions while driving at the slow speeds common in urban areas or congested traffic.

When driving at low speeds (approximately 4 - 30 km/h) a laser sensor mounted on the windsheild senses the car in front. If the system detects a risk of collision, it prepares the brake system to be ready to deliver maximum stopping power when the driver brakes. If the driver does not take evasive action such as braking or steering, the system simultaneously applies the brakes and reduces engine output, with the aim of avoiding the collision or reducing the severity of impact.

* SCBS may not perform as expected due to factors such as the shape of the vehicle in front (some shapes do not reflect laser well, etc.), bad weather (rain, snow, fog, etc.), and road conditions (multiple curves, etc.).

* SCBS is designed to reduce the risk of accidents by helping the driver avoid frontal collisions at slow speeds. However the system has its limitations, and no safety system or combination of such systems can prevent all accidents.These systems are not a replacement for safe and attentive driving. Please drive carefully at all times and do not rely on technology to prevent an accident. Not all of these systems are available on all models or in all markets, so please contact your local Mazda dealer for details on availability. Please refer to your owners' manual for additional important system details, limitations and warnings.

Smart City Brake Support [Forward/Reverse] (SCBS F/R) and Acceleration Control for AT

Smart City Brake System [Forward] (SCBS F) uses a windscreen-mounted near-infrared laser, highly accurate over short distances, to detect vehicles in front of the car. The system works at speeds of approximately 4 – 30 km/h, taking control of the brakes when there is a high risk of collision. If the driver applies the brakes at this point, the system assists, instantly increasing the braking force. If the driver fails to apply the brakes, the system will brake automatically with the aim of avoiding the collision or at least reducing the severity of impact. In addition, SCBS F features Acceleration Control for AT. When the car is stopped or crawling at speeds of less than 10 km/h and the accelerator pedal is pressed suddenly, as if the driver really intends to brake, an alarm is sounded and engine power is cut off, stopping the car from lurching forward.

Smart City Brake System [Reverse] (SCBS R) uses two ultrasonic sensors mounted on the bumper to keep track of obstacles when reversing at low speeds (approximately 2 – 8 km/h). If there is a risk of collision the system applies the brakes automatically, minimizing damage resulting from any impact.

In addition, SCBS R features Acceleration Control for AT. When the car is stopped or reversing at speeds of 10 km/h or less and the accelerator pedal is pressed suddenly, as if the driver really intends to brake, an alarm is sounded and engine power is cut off, stopping the car from lurching backwards.

* SCBS F, SCBS R and Acceleration Control for AT may not function appropriately due a variety of factors, including the shape of the target (some vehicle designs do not reflect radar well and ultrasonic sensors have difficulty detecting objects that are small, thin, low to the ground, etc.), weather conditions (including rain, snow, fog, etc.), and road conditions (repeated or tight curves and/or steep undulations, etc.).

* SCBS F, SCBS R and Acceleration Control for AT are designed to alleviate the burden of driving and reduce damage resulting from accidents and are predicated on the driver operating the vehicle in a safe manner. It is important to be aware of the limitations of the systems and drive safely at all times.

* Please check the owner’s manual or consult with sales staff for additional important system details, limitations and warnings.

SBS (Smart Brake Support)

Using a millimeter-wave radar Smart Brake Support (SBS) is capable of detecting vehicles and obstacles as far as 200 m ahead. When a risk of collision is detected, the system slows the car via a two-stage brake operation.

SBS aims to help the driver avoid or reduce the severity of collisions, particularly when driving at mid- to high speeds (between 15 km/h and 145 km/h), by automatically applying the brake if there is a danger of collision.

Also, the SBS is coupled with the Distance Recognition Support System (DRSS) that visually displays the distance to the vehicle ahead and Forward Obstruction Warning (FOW) that warns the driver of a risk of collision with the car ahead by alarm and a warning light on the meter. These systems help the driver to maintain the safe following distance.

* SBS may not perform as expected due to factors such as the shape of the vehicle in front (some shapes do not reflect radar well, etc.), bad weather (rain, snow, fog, etc.), and road conditions (multiple curves, undulations, etc.).

* SBS is designed to reduce the risk of accidents by slowing the car when a risk of collision is detected. However the system has its limitations, and no safety system or combination of such systems can prevent all accidents. These systems are not a replacement for safe and attentive driving. Please drive carefully at all times and do not rely on technology to prevent an accident. Not all of these systems are available on all models or in all markets, so please contact your local Mazda dealer for details on availability.
