Adjusting the front radar sensor (FRS)

NOTE: TECHNICAL INFORMATION
Notes on the adjustment of the ACC sensor are a fundamental requirement for these repair instructions and must be complied with at all times.
For additional information see: INSTRUCTIONS FOR ACC ADJUSTMENT DEVICE .

NOTE: TECHNICAL INFORMATION
If there is a "Sensor misadjusted" fault memory entry" and a correct sensor alignment using the adjustment screw is not possible, there is a suspicion of front impact damage.
In this case, the vehicle must be carefully inspected for damage. If necessary, damaged parts must be replaced. Then adjust the ACC sensor again.
A damaged/bent holder indicates a mechanical misuse of the vehicle and will not be considered to be a warranty case.
