  6. Sensor activation conditions
    1. BSD & LCA switch (indicated by the switch LED) is on.
    2. Vehicle Speed: 30 km/h or faster
    3. Curvature radius: 125 m or more
    4. Relative car speed: -10 - 250 km/h

      (Negative value refers to overtaking the vehicle ahead.)

  7. Sensor deactivation conditions
    1. BSD & LCA switch (indicated by the switch LED) is off.
    2. Vehicle Speed: 28 km/h or slower
    3. Curvature radius: 125 m or less
    4. Relative car speed: All except -10 - 250 km/h

      (Negative value refers to overtaking the vehicle ahead.)

  8. System control prohibition
    1. The radar is covered by debris: System conditions - Blockage message is outputted

      Information 

      Contamination of sensors on rear bumper by snow, mud or stickers may result in degradation in sensor detection performance.

    2. The radar installation is distorted due to external impact: Send the error code
    3. BSD & LCA system fails: Send the error code
    4. The radar is overheated: System conditions - Over Temperature message is set off.
    CAUTION:
    • If the surrounding area of rear bumper is contaminated by foreign materials that may interfere radar, error message can be set off although BSD system is normal.
    • Temporary overheating of radar may set off error (overheating) message although BSD system is normal.
  9. Rear Cross Traffic Alert (RCTA)
    Item Specification Remarks
    Vehicle speed 0 to -10 km/h R' position
    Relative speed 4 - 36 km/h +: closing
    Operating range 0.5 - 20 m Vehicle: 20 m
    Bike: 15 m
    1. This function helps the driver to detect an approaching vehicle from the rear and side that cannot be visually identified when the driver reverses to pull the vehicle out from a parking spot.
    2. A warning is generated for the target vehicle if it is within 2 seconds based on TTC (Time to Collision). Pedestrians are not considered as approaching targets when warning the driver. (Warning may not be generated.)

      Information 

      Time to Collision (TTC): If the predicted time to collision calculated by taking into consideration the relative distance and relative speed to the target vehicle is within 2 - 3.5 seconds, the warning alarm will be set off. (It changes depending on the relative speed of the approaching vehicle.)
