Display of TELE AID status, function - GF82.95-P-2015GZU

MODEL 164 with CODE (359) TELE AID emergency call system with CODE (494) USA version 

The SOS button SOS (S93/3) and MB-Info and telediagnosis button group (S93/6) serve for display of the status in the emergency call system. The LEDs integrated into the buttons indicate the specific status.

The emergency call system control unit (N123/4) performs a self-test after circuit 15R has been active for approx. 3.5 s. If the test is successful, the system is ready for operation.

Actuation of an emergency call 

Actuation of an emergency call (automatic or manual) is indicated by the LED in the SOS button flashing.

Actuation of a telematics service 

Either an MB-Info call or breakdown assistance call is activated when the buttons in the MB-Info and telediagnosis button group are pressed. This is indicated by a flashing LED in the button pressed.

Error displays 

If an error occurs in the system, the LEDs in the SOS button and on the MB-Info and telediagnosis button group come on. In the event of an error, an error message appears in the multifunction display (A1p13) in the instrument cluster (A1) and in the display for the COMAND operating, display and control unit (A40/3).

Deactivation of the status display must be confirmed by the customer to the dealer, in writing, on a preprinted form.
