NOTES ON ACC ADJUSTING DEVICE (FRR SENSOR)

NOTE: This document applies to the entire F series with the new ACC sensor (FRR - Full Range Radar).

NOTE: The following step must be taken if there is an "Incorrectly adjusted sensor" fault entry or there is a suspicion of frontal damage:

IMPORTANT: The vehicle must be parked on a flat, horizontal surface!

NOTE: For purposes of clarity, graphic shows holder (1) removed.

Hold square (2) against holder (1) as shown.

Limit stop leg length: approx. 105 mm Check vertical orientation in direction of travel with bubble level (3).

Replace holder if necessary.

IMPORTANT: After replacing the holder, check the ACC sensor position again using the square (2) and bubble level (3).

If the ACC sensor position is still not right, check the support for the bumper panel at the bottom front for damage and replace if necessary. CHECK THE SUPPORT FOR THE BUMPER PANEL AT THE BOTTOM FRONT FOR DAMAGE AND REPLACE IF NECESSARY.

A damaged/bent holder (1) indicates mechanical misuse of the vehicle and cannot be handled as a warranty case.
