Radar Sensors (Some Models)

Radar Sensors (Some Models)

The radar sensor detects objects by sending radio waves in a specific direction and receiving the reflected waves back.

Vehicle front

  1. Front radar sensor (Some Models)

 

Vehicle rear

  1. Rear side radar sensors (Some Models)

 

  • Heed the following cautions so that the radar sensors can function normally.

    • Do not modify the suspensions.

    • Use the specified tire size and the same type of tire on all 4 wheels. In addition, do not use tires with significantly different wear patterns or tire pressures on the same vehicle (including temporary spare tire).

    • Do not spray highly pressurized water against the radar sensors or rub them strongly.

    • Do not apply stickers on parts near the radar sensors.

    • If foreign matter adheres to parts near the radar sensors, remove it and switch the vehicle power OFF. The foreign matter detection status is reset by switching the vehicle power OFF.

    • Consult an Authorized Mazda Dealer if you need to repair, replace, or paint parts near the radar sensors.

    • Do not install any parts that cover the front of the radar sensors.

    • Do not replace the front radar sensor cover with anything other than a genuine product.

  • If strong force is applied to parts near the radar sensors, the direction of the radar sensor may become deviated and each system may not operate normally. Stop each system immediately and have the vehicle inspected by an Authorized Mazda Dealer.

  • The radar sensors include a function for detecting abnormalities in the sensor, soiling of the sensor’s front surface, and informing the driver. If a message appears on the screen that can be addressed, follow the directions of the message.

Front radar sensor

The following systems utilize the front radar sensor.

  • Distance & Speed Alert (DSA)

  • Mazda Radar Cruise Control (MRCC)

 

  • When driving on roads with few vehicles ahead, a message may temporarily be displayed on the screen indicating that the front radar sensor is dirty.

  • When the vehicle is driven on roads in which there is an elevated road on one side, the front radar sensor function may be restricted temporarily.

  • If the lead-acid battery power is weak, the front radar sensor detection function may decrease and each system may not operate normally.

  • When any of the following conditions is met, the front radar sensor may not be able to detect vehicles ahead or obstructions correctly.

    • During inclement weather.

    • Front visibility is reduced.

    • The vehicle is driven near facilities or objects emitting strong radio waves.

    • The rear surface of a vehicle ahead does not reflect radio waves effectively.

    • A vehicle ahead has limited areas that can reflect radio waves.

    • Your vehicle is tilted.

    • Foreign matter is adhering to parts near the front radar sensor.

  • When any of the following conditions is met, the front radar sensor may detect vehicles in the adjacent lane or surrounding obstructions, or it may not be able to detect vehicles ahead or obstructions.

    • The vehicle is entering or exiting a curve.

    • The vehicle is driven on a continuously curving road.

    • The vehicle is driven on roads with repeated up and downslopes.

    • The vehicle is driven on roads with narrow lanes.

    • The vehicle is driven on poor roads or unpaved roads.

    • The vehicle ahead enters the front radar sensor’s blind spot.

    • The distance to the vehicle ahead is extremely close.

    • The vehicle ahead is being driven in an unstable condition.

    • A vehicle suddenly comes close such as by cutting into your lane.

Rear side radar sensors

The following systems utilize rear side radar sensors.

  • Blind Spot Monitoring (BSM)

  • Blind Spot Monitoring (BSM) Vehicle Exit Warning

  • Rear Cross Traffic Alert (RCTA)

 

  • When any of the following conditions is met, the rear side radar sensors may not be able to detect target objects.

    • During inclement weather.

    • The vehicle is driven on a sharp curve or on bumpy roads.

    • Radar sensor from an adjacent vehicle causes radio wave interference.

    • The detection range of a front side radar sensor is obstructed by an adjacent wall or vehicle, or the radar is reflected.

    • A vehicle suddenly enters the detection range from the front or side of your vehicle.

    • The target object is extremely small.

    • The target object is extremely low/high.

    • A vehicle approaches while turning.

    • A vehicle that has stopped suddenly starts to move.

    • Multiple objects move at the same time.

    • The bumper around a rear side radar sensor is deformed.

    • Foreign matter is adhering to the bumper around a rear side radar sensor.

    • The temperature near a rear side radar sensor is extremely hot.

  • The rear side radar sensors may not detect the following target objects.

    • Animals.

    • Pedestrians.

    • Bicycles and small motorcycles moving at a low speed.

    • Shopping carts.

    • Stationary objects on the road or roadside.

    • Vehicles with shapes that may not reflect radar waves.

    • A vehicle is traveling alongside your vehicle at nearly the same speed for an extended period of time.
