Controls in detail Useful features Upgrade signals The 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 beep and voice contact will be interrupted. Voice contact will resume once the retransmission is completed. Once a call is concluded, a beep will be heard and the respective indicator lamp will stop flashing. The COMAND* system operation will resume. ! 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 Customer Assistance at 1-800-FOR-MERCedes (1-800-367-6372) in the USA or Customer Service at 1-800-387-0100 in Canada. i When a Tele Aid call has been initiated, the audio system or the COMAND* system audio is muted and the selected mode (radio, tape or CD) pauses.
