Notes on Emergency Requests
Do not use the voice activation system to initiate an Emergency Request. In stressful situations, the voice and vocal pitch can change. This can unnecessarily delay the establishment of a telephone connection.
Instead, use the SOS button, in the vicinity of the interior mirror.
