    HINT: 

    The millimeter wave radar sensor assembly is fixed to the front bumper assembly. If the installation position of the front bumper assembly is misaligned, the beam axis will also be misaligned. Therefore, when the front bumper assembly is deformed, even if the millimeter wave radar sensor assembly beam axis is manually changed or the millimeter wave radar sensor assembly is replaced, the millimeter wave radar sensor assembly beam axis adjustment may not complete.

    1. Remove the upper radiator support seal.

      Refer to PROCEDURE - Step 17
