when the indicator lamp does not come
on in red or stays on longer than
approximately ten seconds.
If the indicator lamp on the Information
button ¡ is flashing continuously
and there was no voice connection to
the Response Center established, then
the Tele Aid system could not initiate
an Information call (e.g. the relevant
cellular phone network is not
available). The message
Call failed
appears in the multifunction display.
Information calls can be terminated
using the t button on the
multifunction steering wheel or the
respective button for ending a
telephone call on the audio system or

ing after pressing one of the buttons or

currently active, and may not initiate a
call. Visit an Mercedes-Benz Center
and have the system checked or con-
tact the Response Center at
