The ETC simplifies the process of payment on toll roads. It settles payment procedures automatically without the driver having to stop the car.

Function sequence 

The Electronic Toll Collection antenna (ETC) (A2/94) and Electronic Toll Collection control unit (ETC) (A50/3) are installed in the vehicle for transmitting and receiving the data. The Electronic Toll Collection (ETC) control unit communicates with the toll booth via the Electronic Toll Collection (ETC) antenna. For automatic payment a special ETC card must be inserted into the electronic toll collection (ETC) control unit. All information concerning the user and the fees that have already been paid are stored on this ETC card. In the vehicle the Electronic Toll Collection (ETC) control unit is connected via an RS-232C interface to the COMAND operating, display and controller unit. The ETC also has voice output and visual output (pop-ups).

The voice output is:

• ETC card read error
• ETC card not accepted
• ETC card reader error
• ETC gate communication error
• Detailed information on the last fees paid (menu, navi, navi menu, ETC history)
• ETC card not inserted

Visual output (pop-ups) on the display on the COMAND operating, display and controller unit:

• COMAND operating, display and controller unit booted and no ETC card inserted
• COMAND operating, display and controller unit booted and ETC card inserted
• Positive feedback from toll booth
