Starting the direct current charging process (mode 4)

DANGER Risk of death when charging at a damaged socket

The charging process uses high voltage.

If the charging cable, the vehicle socket or the mains socket are damaged, you could receive an electric shock.

Only use an undamaged charging cable.

Avoid mechanical damage such as crushing, abrading or driving over the cable.

Have a damaged vehicle socket replaced at a qualified specialist workshop as soon as possible.

Never connect the charging cable to a damaged vehicle socket.

NOTE Protecting the vehicle from voltage surges in the mains supply

The vehicle is equipped with an electrical fuse for voltage surges in the mains supply. This electrical fuse may be blown during severe thunderstorms, for example, and may cause the building's circuit breaker to trip and the charging process to be interrupted. These functions help to protect the vehicle.

After the building protection system has been switched on again, the charging process resumes automatically.

Following an interruption in the power supply in which the building's circuit breaker is not tripped, it may take up to ten minutes for the charging process to resume automatically.

NOTE Permissible heat generated by the charging cable and charging cable connector

During the charging process, the charging cable and charging cable connector may heat up within permissible limit values.

The permissible limit values are observed provided that:

The mains power supply and the charging cable are not damaged.
The instructions for handling the charging cable and controls on the charging cable have been followed.

If the charging cable or the charging cable connector becomes too hot, have the mains power supply equipment checked.

NOTE Damaged or dirty vehicle socket when the socket flap is open

Always keep the socket cover and the socket flap closed when there is no charging cable connected. This protects the vehicle socket from dirt and damage.

Make sure that the socket cover is closed properly before closing the socket flap. This can otherwise result in damage which may prevent the socket flap from being opened again.

Requirements:

The transmission is in position .
The vehicle is unlocked or the distance between the key and the vehicle does not exceed 1 m.
The hybrid system is not activated. The indicator on the multifunction display is off.
The charging cable is not taut.

Depending on the national version, the vehicle is equipped with one of the following vehicle sockets.

Combo 1 vehicle socket

Combo 2 vehicle socket

Press the rear centre of socket flap

and fold open the socket flap.

The indicator lamp and status display light up white.

When the hybrid system is activated (the display is lit in the multifunction display), socket flap cannot be opened.

Press catch

to the left and fold open socket cover

The CCS charging cable connector requires connections and . Therefore, it is necessary to open both parts of socket cover .

Insert the CCS charging cable connector into the vehicle socket to the stop.

Make sure that the charging cable is not taut when inserted.

The indicator lamp and status display flash orange and, as soon as the high-voltage battery is charged, green.

If the charging cable is connected to the vehicle, the drive system cannot be started and the vehicle cannot be moved.

At the start of the charging process, the charge level display is shown in the instrument cluster with a charging prediction. The charging prediction either refers to the predicted charge level at the set departure time, or the time at which the high-voltage battery will be fully charged.

Depending on the temperature, the fan and battery cooling system may audibly switch on during the charging process.

If the vehicle is idle for lengthy periods and connected to the mains supply, the high-voltage battery will be recharged automatically as needed or when electrical consumers are activated (e.g. the pre-entry climate control).
