DANGER
High-voltage systems in the electric motor compartment and in other places on the vehicle can cause electrical shocks or even electrocution, severe burns, other serious injuries, and even death!
x Always assume that the high-voltage battery is fully charged and that all high-voltage components are live.
x Touching damaged orange high-voltage cables, the high-voltage battery or other parts of the high-voltage electrical system can cause fatal electric shock.
x The high-voltage system may also be active even when the ignition is switched off!
x Electrolyte fluid in the high-voltage battery will cause severe chemical burns. If electrolyte fluid contacts skin, thoroughly flush affected area with clean water for at least 15 minutes and then wash affected area with soap and water; medical attention is recommended.
x Never attempt to carry out any work on the high-voltage network, the high-voltage cables or the high-voltage battery.
x Never open, maintain or repair components or parts of the high-voltage network, and nev-er disconnect them from the network.
x Never damage, change or remove the orange high-voltage cables or disconnect them from the high-voltage network.
x Never open, modify or remove the cover of the high-voltage battery.
x Any work on the high-voltage system, or on systems which could be indirectly affected by it, must only be carried out by properly trained and qualified experts.
x Work in the vicinity of high-voltage components and high-voltage cables with machinery, sharp-edged tools or heat sources, for example, welding, soldering, hot air or thermal adhe-sives, may only be performed after the high-voltage components have been disconnected. Only properly qualified and trained specialist staff may work on the high voltage compo-nents.
x The Volkswagen standards and guidelines must be adhered to when carrying out any work on the high-voltage network or the high-voltage battery.
x During such work, keep the vehicle key safe and far enough away from the vehicle to pre-vent any risk of the ignition being accidentally switched on and the electrical system activat-ed (particularly in vehicles with Keyless Access).
x Any gasses emitted by or escaping from the high-voltage battery may be toxic or flamma-ble.
x Damage to the vehicle or to the high-voltage battery could lead to a leak of toxic gases, either immediately or at a later time. These emitted gases could also potentially cause a fire. If damage has been incurred, it is vital to then open the vehicle windows to allow any emitted gases to disperse. Do not inhale these gases.
x Never touch or inhale any liquids or gasses leaking from the high-voltage battery, espe-cially if the battery has been damaged.
x Remember to inform any attending emergency services that the vehicle is equipped with a high-voltage battery.
Warning and indicator lights

Lights up Text message ⇒  Proper response

The current charge level of the high-voltage battery is displayed in the instrument cluster ⇒ fig. 133.
The current range is also shown on the instrument cluster display ⇒ fig. 9.
When the high-voltage battery is fully charged, the needle in the charge level display points to 1.
the charge level of the high-voltage battery has reached the “reserve range” (A) or the vehicle is driving in the reserve range, various indicator lights will light up in the instrument cluster and text
messages will appear in the instrument cluster display ⇒ fig. 9. Charge the high-voltage battery as soon as possible.
WARNING
Driving when the high-voltage battery charge level is too low can lead to stalling in traffic, collisions and serious personal injury.
x Always make sure that the high-voltage battery has enough charge to get where you are going and that the high-voltage battery can be charged when you get there.

Enabling the charging process
After a successful self-test, press the button (1) to set the protection unit to ready and enable the charging process. The LED in the protection unit symbol (2) lights up green.
Ending the charging process
If you want to interrupt the high-voltage battery charging process before charging is completed, the charging process must be interrupted or ended on the vehicle
Checking the Ground Fault Circuit (GFI) of the 110 Volt outlet
The GFI should be checked once a month. Carry out this procedure with the charging cable connected to the 110 Volt outlet and the vehicle. The charging process has to be deactivated:
x Press the test button (3) on the control unit of the charging cable for at about 3 seconds.
x If the test was successful, the warning lights (1) and (2) will light up. Should these warning lights not light up or other lights should light up or flash, an error occurred while testing.
x After a successful test and if error occurred, you can start the charging process by pressing the rest button (6) for at least 3 seconds.
