Temperature monitoring
During the charging process the charging cable can become slightly warmer. This is normal and no cause for concern
If the control unit or the charging cable becomes too hot, the charging current will automatically be reduced If the control unit or the charging cable continues to get hot even at the lowest charging current, the protection unit will be switched off, and will remain switched off until it has cooled down sufficiently.
If no other sources of heat, such as direct sunlight, can be identified as relevant, have the outlet checked by properly qualified and trained experts.
Charging cable for charging at charging stations (if equipped)
Keep the charging cable for charging at a charging station safely in its bag in the luggage compart-ment. Follow the operating manual for the charging station. Before using the charging cable, read the procedure for charging with alternating current
WARNING
Charging the high-voltage battery improperly, using improper or damaged outlets and charg-ing cables, improper handling of the high-voltage battery or failure to follow safe charging procedures can cause short circuits, electric shock, explosions, fire, burns, injuries and death.
x Always connect the charging cable to a properly functioning 110 Volt Ground Fault Circuit (GFI) wall outlet. The outlet must be properly protected from water, moisture and other fluids.
x Always check the fuse protection of the GFI outlet before connecting the charging cable.
x Never connect the charging cable to a conventional power outlet, regardless of whether the outlet is protected or not.
x Never use the charging cable with an extension cord of any kind.
x Never let plugs or connectors come into contact with water, moisture, or any other fluids.
x Never use any charging cable if it is damaged and never use the charging cable with a damaged GFI outlet.
x Never attempt to alter or repair cables or other electrical components.
x Never let anybody stay in the vehicle while the high-voltage battery is charging.
x Never do any kind of work on the outside or inside of the vehicle while the high-voltage battery is charging.
x Always disconnect the charging cable completely from the vehicle before starting the motor.
WARNING
If you are not familiar with the outlet or the electrical installation or it has not been checked by qualified experts, never use it for charging. Even very low charging currents can cause serious damage and in particular fires if the socket or electrical installation is in bad condi-tion. If necessary, get expert assistance from a qualified electrical installation specialist.
WARNING
If a 110 Volt outlet is being used for charging, never charge 2 or more vehicles on outlets of the same fuse at the same time. Use a different fuse circuit for charging another vehicle. Al-ways comply with the maximum load for the fuse circuit used. If necessary, get expert assis-tance.

NOTICE
The supplied charging cable for 110 Volt outlets should always be carried in the vehicle.
NOTICE
Always follow the manufacturer's information and instructions on using the charging station.
NOTICE
The supplied charging cable for 110 Volt outlets has been developed and approved for this vehicle. Do not use the charging cable to charge other vehicles. This applies in particular for vehicles that do not have DC residual current protection.
NOTICE
Always end the charging process before disconnecting the charging cable.
NOTICE
Always connect the charging cable directly to a 110 Volt outlet. Never use the charging cable together with an extension cable, a cable reel, a multiple socket outlet or an adapter such as a regional adapter or timer.
If the charging cable is connected to a 110 Volt outlet with other electrical consumers on the same electrical circuit, the fuse in the electrical circuit can be triggered. If this happens the high-voltage battery will not be charged. Switch off other consumers on the electrical circuit or choose another electrical circuit. If necessary, have the electrical installation checked by qualified experts.
Protect the control unit on the charging cable and the connector from heat, especially from sunlight, during charging.
If the vehicle is close to high-voltage cables during charging, charging may be restricted.
