2020 Mercedes Benz Truck ML 350 Technical Service Bulletin # S-80_57-56 Date: 100908



Audio System - Radio Interruption Information



Date: September 8, 2010



Order No.: S-B-80.57/56



Group: 80



SUBJECT:



MY-All, Models 129, 163, 164, 170, 171, 199, 202, 203, 204, 207, 208, 209, 210, 211, 212, 215, 216, 219, 220, 221, 230, 251, 463



Interruptions in Radio-Operated Vehicle Systems



In the frequency range of the transmitter key or KEYLESS-GO, many other radio-operated Systems can also be transmitting and with a stronger



signal. Systems such as, radio frequency headphones, radio thermometer, garage door opener, alarm systems, etc. can prevent or interrupt unlocking,



locking, and engine starting via a KEYLESS-GO.



Fortunately, in parallel with radio remote control, most MB vehicles also have infrared remote control, so that even with radio disturbance, the



transmitter key will unlock and lock at short range. Exceptions are the 163 and the 170 as they do not have additional infrared remote control, but the



mechanical key will always work.



Advise customers that taking a vehicle key is always recommended as it is conceivable that a criminal might use a radio interferer to block the



locking of a vehicle. Locking is ensured by 3-signal flashing.
