Set Cruise Control Speed Not Displayed in Instrument Cluster Multifunction Display

If you receive customer reports in the above model vehicles of the set cruise control speed not being displayed in the status line of the lower instrument cluster malfunction display, this may be caused by the software in the instrument cluster. The software does not support the function for displaying the set cruise control speed. Instrument clusters with the following MB software object numbers do not support this function.

A171 442 00 00
A171 442 00 21
A171 442 01 21
A171 442 02 21

The MB software object number can be checked using STAR Diagnosis, navigate to the following menu: Control units -> Information & Communication -> Instrument cluster -> control unit version

Do not replace parts for this condition. This is normal functionality of those instrument clusters.
