Advanced Smart Cruise Control (ASCC) Radar Sensor Alignment

Advanced Smart Cruise Control (ASCC) unit detects a vehicle in front and then calculates the distance to the vehicle in front and the relative speed by using the built-in radar sensor.

In order for the radar sensor to operate correctly, it must be properly aligned parallel to the driving direction of the vehicle. For this reason, the radar sensor alignment procedure must be carried out whenever the sensor has been reinstalled or replaced with a new one.

If the sensor alignment procedure is not performed in the conditions mentioned above, the smart cruise control system may not operate correctly.

1. Park the vehicle on a level ground.
   NOTE:

   • Adjustment may not be accurate if the vehicle and reflector are placed on different ground levels or on a slope.
   • Perform in an area with minimum clearance of 8 m to the front, 4 m wide, and 1.2 m above the ground.
   • Remove heavy objects from inside of the vehicle (seating area and trunk).
   • Ensure that all tires are filled with specified air pressure.
   • Remove objects (metal plates, resins, etc.) that may cause electric signal interference from the area where sensor alignment is performed.
   • Be sure that the vehicle is not moved and free from vibration when performing sensor alignment (getting in/out or opening/closing doors).
   • Check that radiator grille and sensor cover are not dirty.
   • Check for correct wheel alignment.
   • Do not turn OFF the power when performing sensor alignment.
   • Power supplied to the radar sensor must be between 9V~16V.
   • Temperature in the area where sensor alignment is performed must be between -30~60°C.

15. Visually check again the radar sensor and the surface of the front bumper for the following.
    NOTE:

    • Make sure that there is no debris, or reflecting object on the surface of the radar.
    • Make sure that there is no debris, or reflecting object on the radiator grille.
16. Connect the KDS/GDS to the DLC of the vehicle and start sensor alignment.
    NOTE: If the engine is running, the vibration may cause inaccurate sensor alignment, so perform sensor alignment in IG ON mode.
17. After correctly selecting the vehicle model, select "SCC Alignment" from the auxiliary functions in KDS/GDS Menu.
