Important!

If the indicator lamps do not start flashing after
pressing one of the buttons or remain illuminated (in
red) at any time, the Tele Aid system has detected a fault
or the service is not currently active, and may not
initiate a call. Visit your Mercedes-Benz Light Truck
Center and have the system checked or contact the
Response Center at 1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon as possible.

Upgrade Signals

Tele Aid system processes calls using the following
priority.

Automatic emergency – First priority

Manual emergency – Second priority

Roadside assistance – Third priority

Information – Fourth priority

Should a higher priority call be initiated while you are
connected, an upgrade (alternating) tone will be heard,
and the appropriate indicator lamp will flash. If certain
information such as vehicle identification number or
customer information is not available, the operator may
need to retransmit. During this time you will hear a
chirp and voice contact will be interrupted. Voice
contact will resume once the retransmission is
completed. Once a call is concluded, a chirp will be
heard and the appropriate indicator lamp will stop
flashing. The MCS system operation will resume.
