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 client 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 complete. Once a call is concluded, a chirp will be heard, the appropriate indicator lamp will stop flashing and a tone will be heard indicating that the system has reset. Important! If the indicator lamp continues to flash or the system does not reset, contact the Response Center at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in Canada), or Mercedes-Benz Client Assistance at 1-800-FOR-MERCedes (1-800-367-6372) in the USA or Customer Service at 1-800-387-0100 in Canada. Notes: The indicator lamp in the respective button flashes until the call is concluded and this can only be completed by a Response Center or Client Assistance Center representative.
