Hyundai Palisade. Detecting Sensor

The rear radars are located inside the rear bumper for detecting the side and rear areas. Always keep the rear bumper clean for proper operation of the system.


  • The system may not work properly when the bumper has been damaged, or if the rear bumper has been replaced or repaired.
  • The system may turn off if interfered by electromagnetic waves.
  • Always keep the sensors clean.
  • NEVER disassemble the sensor component or apply any impact on the sensor component.
  • Be careful not to apply unnecessary force on the radar sensor or sensor cover. If the sensor is forcibly moved out of proper alignment, the system may not operate correctly. In this case, a warning message may not be displayed. Have the vehicle inspected by an authorized HYUNDAI dealer.
  • Do not apply foreign objects such as a bumper sticker or a bumper guard near the radar sensor or apply paint to the sensor area. Doing so may adversely affect the performance of the sensor.

Warning message

Hyundai Palisade. Detecting Sensor

Blind-Spot Collision Warning (BCW) system disabled. Radar blocked

This warning message may appear when:

- One or both of the sensors on the rear bumper is blocked by dirt or snow or a foreign object.
- Driving in rural areas where the sensor does not detect another vehicle for an extended period of time.
- When there is inclement weather such as heavy snow or rain.

If any of these conditions occur, the light on the BCW/BCA switch and the system will turn off automatically.

When the BCW canceled warning message is displayed in the cluster, check to make sure that the rear bumper is free from any dirt or snow in the areas where the sensor is located. Remove any dirt, snow, or foreign material that could interfere with the radar sensors.

After any dirt or debris is removed, the system should operate normally after about 10 minutes of driving the vehicle.

If the system still does not operate normally have your vehicle inspected by an authorized HYUNDAI dealer.


Turn off the BCW and RCCW system when a trailer or carrier is installed.

- Press the BCW/BCA switch (the indicator on the switch will turn off)
- Deactivate the RCCW system by deselecting 'User Settings → Driver Assistance → Parking Safety → Rear Cross-Traffic Collision Warning'
