Controls in detail Useful features Emergency calls An emergency call is initiated automatically following an accident in which the emergency tensioning devices (ETDs) or air bags deploy. An emergency call can also be initiated manually by opening the cover next to the interior rear view mirror labeled SOS, then briefly pressing the button located under the cover. See ( page 253) for instructions on initiating an emergency call manually. Once the emergency call is in progress, the indicator lamp in the SOS button will begin to flash.

All information relevant to the emergency, such as the location of the vehicle (determined by the GPS satellite location system), vehicle model, identification number and color are generated. A voice connection between the Response Center and the occupants of the vehicle will be established automatically soon after the emergency call has been initiated. The Response Center will attempt to determine more precisely the nature of the emergency provided they can speak to an occupant of the vehicle. The Tele Aid system is available if it has been activated and is operational Activation requires a subscription for monitoring services, connection and cellular air time. the relevant cellular phone network and GPS signals are available and pass the information on to the Response Center Warning! G If the indicator lamp in the SOS button is flashing continuously and there was no voice connection to the Response Center established, then the Tele Aid system could not initiate an emergency call (e.g. the relevant cellular phone network is not available). The message Call Failed appears in the multifunction display for approximately 10 seconds. Should this occur, assistance must be summoned by other means. i Location of the vehicle on a map is only possible if the vehicle is able to receive signals from the GPS satellite network and pass the information on to the Response Center. 252
