The charger feed-in socket (charge socket) is

located on the right rear B-pillar under a flap.

The socket is fitted with a folding protective

cover. Different versions are installed depending

on the national version of the vehicle (ECE,

USA/Canada).

ECE version

The 7-pin socket has 5 high-voltage contacts (L1,

L2, L3, N and PE) for the alternating voltage feed

and 2 signal contacts for Control Pilot (CP) and

Proximity (PP). The CP contact is used for data

exchange with the charging station and the PP

contact allows the vehicle to detect when the

charging cable is plugged in. On vehicles with the

3 kW on-board charger, only high-voltage

contacts L1, N and PE are used. There are 2 indi-

cator lamps above the socket which indicate

locking of the charging connector and the status

of the charging process.
