Radar sensors (rear)

The radar sensors (rear) function by detecting the radio waves reflected off a vehicle approaching from the rear or an obstruction sent from the radar sensors. The following systems also use the radar sensors (rear).

  • Blind Spot Monitoring (BSM)

  • Rear Cross Traffic Alert (RCTA)

The radar sensors (rear) are installed inside the rear bumper, one each on the left and right sides.

Refer to Radar Sensors (Rear) (Search).

Ultrasonic sensors (rear)

The ultrasonic sensors (rear) function by detecting the ultrasonic waves reflected off obstructions at the rear sent from the ultrasonic sensors. The following systems also use the ultrasonic sensors (rear).

  • Smart City Brake Support [Reverse] (SCBS R)

The ultrasonic sensors (rear) are mounted in the rear bumper.

Refer to Ultrasonic Sensors (Rear) (Search).

Front camera/side cameras/rear view camera

The front camera, side cameras, and rear camera shoot images of the area surrounding the vehicle. The 360° View Monitor uses each camera.

Cameras are installed to the front bumper, door mirrors, and liftgate.

Refer to Front Camera/Side Cameras/Rear Camera (Search).

High Beam Control System (HBC) (Some Models)

To Operate the System

The HBC operates to switch the headlights automatically between high and low beams after the ignition is switched ON and the headlight switch is in the AUTO and high beam position.

The HBC determines that it is dark based on the brightness of the surrounding area. At the same time, the HBC indicator light (green) in the instrument cluster illuminates.

 

 

  • When the vehicle speed is about 30 km/h (19 mph) or more, the headlights automatically switch to high beams when there are no vehicles ahead or approaching in the opposite direction.

    When the vehicle speed is less than about 20 km/h (12 mph), the HBC switches the headlights to low beams.

  • The low beams may not switch to high beams when cornering.

  • Operation of the HBC function can be disabled. Refer to the Settings section in the Mazda Connect Owner's Manual.

Smart City Brake Support [Reverse] (SCBS R) (Some Models)

Smart City Brake Support [Reverse] (SCBS R) (Some Models)

The SCBS R is a system which is designed to reduce damage in the event of a collision by operating the brake control (SCBS brake) when the system’s ultrasonic sensors detect an obstruction at the rear of the vehicle while driving at a speed of about 2 to 8 km/h (2 to 4 mph) and the system determines that a collision is unavoidable.

 

Do not rely completely on the SCBS R system:

  • The SCBS R system 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.

  • To assure the correct operation of the SCBS R, heed the following cautions.

    • Do not apply a sticker to an ultrasonic sensor (rear) (including transparent stickers). Otherwise, the ultrasonic sensor (rear) may not be able to detect vehicles or obstructions which could result in an accident.

    • Do not disassemble an ultrasonic sensor (rear).

    • If cracks or damage caused by flying gravel or debris is visible around an ultrasonic sensor (rear), stop using the SCBS R system immediately and have your vehicle inspected by an Authorized Mazda Dealer. If the vehicle continues to be driven with cracks or scratch marks left around an ultrasonic sensor, the system may operate unnecessarily and cause an unexpected accident.

      Refer to Stopping the Smart City Brake Support [Reverse] (SCBS R) System Operation (Search).

    • Consult an Authorized Mazda Dealer for rear bumper replacement.

Do not modify the suspension:

If the vehicle height or inclination is changed, the SCBS R system may not operate correctly because it cannot detect obstructions correctly.

Do not apply a strong force to an ultrasonic sensor (rear):

When washing the vehicle, do not spray highly pressurized water against an ultrasonic sensor (rear), or rub it strongly. In addition, do not hit the rear bumper forcefully when loading and unloading cargo Otherwise, the sensors may not detect obstructions correctly which could cause the SCBS R system to not operate normally, or it could operate unnecessarily.

  • When driving off-road in areas where there is grass or foliage, it is recommended that the SCBS R system be turned off.

  • 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. Otherwise, the SCBS R system may not operate normally.

  • If ice or snow is stuck on the ultrasonic sensors (rear) they may not be able to detect obstructions correctly depending on the conditions. In such cases, the system may not be able to perform controls correctly. Always drive carefully and pay attention to the rear of the vehicle.

    • The engine is running.

    • The selector lever is in the R (reverse) position.

    • “Reverse Smart City Brake Support Malfunction” is not displayed in the multi-information display.

    • The vehicle speed is between about 2 to 8 km/h (2 to 4 mph).

    • The SCBS R is not turned off.

    • The DSC is not malfunctioning.

  • The SCBS R operates using ultrasonic sensors (rear) which detect obstructions at the rear by emitting ultrasonic waves and then receiving the returning waves reflected off the obstructions.

  • In the following cases, the ultrasonic sensors (rear) cannot detect obstructions and the SCBS R may not operate.

    • The height of the obstruction is low such as low walls or trucks with low loading platforms.

    • The height of the obstruction is high such as trucks with high loading platforms.

    • The obstruction is small.

    • The obstruction is thin such as a signpost.
