Controls in detail Useful features Emergency calls An emergency call is initiated automatically: following an accident in which the emergency tensioning detractors (ETDs) or airbags deploy, if the anti-theft alarm or the tow-away alarm stays on for more than 20 seconds. See anti-theft alarm system ( page 78) and tow-away alarm ( page 79). An emergency call can also be initiated manually by opening the cover next to the inside rear view mirror labeled SOS, then briefly pressing the button located under the cover. See below for instructions on initiating an emergency call manually. Warning! G The Tele Aid control unit is located under the front passenger seat. If there is accumulation of water or other liquid in this area, the Tele Aid control unit could suffer an electrical short circuit making the system inoperative. In this case the indicator lamp in the SOS button will not illuminate during or will remain illuminated after the system self-check. Have the system checked at the nearest Mercedes-Benz Light Truck Center as soon as possible. If the indicator lamps in the SOS button, in the Roadside Assistance button and/or in the Information button do not come on during the system self-check or if any of these indicators remain illuminated constantly in red and/or the message TELE AID - VISIT WORKSHOP is displayed in the MCS display after the system self-check, a malfunction in the system has been detected. If a malfunction is indicated as outlined above, the system may not operate as expected. Have the system checked at the nearest Mercedes-Benz Light Truck Center as soon as possible. 161
