Smart Cruise Control (SCC) Sensor Alignment: Notes
Smart Cruise Control (SCC) unit detects foregoing vehicles and then calculates the distance to the foregoing vehicle and the relative speed 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. So, the radar sensor calibration procedure must be carried out after the sensor is reinstalled or replaced with a new one. If the sensor calibration is not performed properly in the above conditions, the smart cruise control system may not operate correctly.
NOTE:
The SCC radar sensor alignment is required when:
- The SCC unit is reinstalled or replaced with a new one.
- The radar sensor or the surrounding parts are impacted by a collision.
- The sensor cannot detect a foregoing vehicle.
- The Steering Angle Sensor (SAS) is replaced or adjusted.
CAUTION:
If the sensor cannot detect a foregoing vehicle:
- Park the vehicle on the level ground.
- Take out heavy luggage from the vehicle seats or trunk.
- Set all tires according to the specified pressure.
- Check wheel alignment.
- Check that the front surface of the SCC unit is clean.
