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.
Refer to Stopping the Smart Brake Support (SBS) System Operation (Search).
-
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.
-
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 (Search).
-
-
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.
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.

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.
