FRONT WHEEL ALIGNMENT ADJUSTMENT

Note


  • When the wheel alignment is performed, or a suspension related part is removed and installed/replaced, make sure to the cable from the negative (-) battery terminal for 2 seconds or more after finishing, and then reconnect the cable and perform initialization.

  • If the vehicle is equipped with a VSC system, when the wheel alignment is performed, or a suspension related part is removed and installed/replaced, always perform the following initialization so that the system can function normally: (1) Disconnect the cable from the negative (-) battery terminal for 2 seconds or more and then reconnect it; then (2) perform the yaw rate sensor zero point calibration and test mode inspection.

  • If the vehicle has an object recognition camera, after the wheel alignment is performed, always adjust the object recognition camera.
