Repair Procedures: Installation

NOTE:
  • Put the vehicle on the level ground.
  • Take out heavy luggage from the vehicles' seats or trunk.
  • Set all tires according to the specified pressure.
  • Check wheel alignment.
  • Check that the front surface of the front radar is clean.
  1. Check the last 2 digits of Lot. No (A) on label at rear side before installing the front radar.

    Information 

    • The meaning of Lot. No (A) is the vertical deviation angle of front radar inner side.

    3. Check the vertical angle which is compensated error on diagnostic tool.

      Information 

      • The result value is final goal vertical angle which is compensated inner error of criteria vertical installation angle -1°.

    4. Check the front radar vertical angle by using the vertical protractor (tilt meter).
      NOTE:
      • Make sure to perform zero setting before using vertical protractor. (perform this procedure periodically)
      • Be careful with +/- readings when finding true vertical using vertical protractor.
    5. Adjust to "target vertical angle" by turning adjusting screw of front radar.
      • turning clockwise: adjusting (+) angle
      • turning counterclockwise: adjusting (-) angle
      NOTE:
      • There is a chance to be transformed of bracket if adjusting screw with over strength.
      • Must recheck with vertical protractor if vertical angle is right after adjusting.

    6. Install the front bumper assembly.

      (Refer to Body - "FRONT BUMPER ASSEMBLY ")

    7. Perform the front radar inspection/correction procedure by using the SST.

      (Refer to Smart Cruise Control (Stop & Go) (SCC) Unit-Radar - "ADJUSTMENT ")
