Tele Aid utilizes the cellular network for
communication and the GPS (Global Positioning
System) satellites for vehicle location. If either of these
signals are unavailable, the Tele Aid system may not
function and if this occurs, assistance must be
summoned by other means.
Wa r n i n g !
The Tele Aid control unit is located under the
driver’s seat. If there is accumulation of water or
other liquid in this area, the Tele Aid control unit
could suffer an electrical short circuit making the
system inoperative. In this case the indicator lamp
in the “SOS” button does not illuminate during or
remains illuminated after the system self-check.
Have the system checked at the nearest
Mercedes-Benz Center as soon as possible.
