Vehicular Mode Operation
When you connect your phone to your Mercedes-Benz vehicle, the phone is ready to operate in Vehicular Mode.
In Vehicular Mode, your phone is connected to many integrated features of your vehicle and its audio system, offering
these advantages:
• You can use your phone in either Hands Free mode or in privacy mode.
• Your phone uses your vehicle’s speakers for better sound fidelity in Hands Free mode.
• Your vehicle charges your phone’s battery when the vehicle is running.
• When you place or receive a call, your vehicle’s radio, CD, and/or tape player volume is automatically muted so you
can hear the person on the other end.
Before you use your phone in Vehicular Mode, you should familiarize yourself with how this system operates.
