Shortly after the completion of your acquaintance call, you will receive a user ID and password via first call mail. By visiting www.mbusa.com and selecting "Tele Aid" (USA only), you will have access to account information, remote door unlock, profile and more. System self-check Initially, after turning the key in the steering lock to position 2, malfunctions are detected and indicated (the indicator lamps in the SOS button, the Roadside Assistance button • and the Information button ¡ stay on longer than 10 seconds or do not come on).
