This allows the new sensor assembly to automatically align to the vehicle during normal customer driving. Refer to Control Module References .
Performance of the ACC system may be degraded after sensor assembly replacement. Normal customer driving will correct the performance of the ACC system. Refer to Cruise Control Description and Operation (Adaptive Cruise) or Cruise Control Description and Operation (Conventional Cruise) .
