Observe the safety precautions > General information, in Battery general information .

Requirement: only use chargers with a maximum charging current of 14.8 volts. The battery cables remain connected.

The charging cable connections are located in the motor compartment. The ground point (-) is always located on the vehicle body.

  • Switch off the ignition and all electrical equipment.
  • Open the hood.
  • Press the release lever on the positive terminal and fold the cover upward > fig. 168.
  • Clamp the terminal clamps on the charger correctly onto the positive terminal (+) and the ground point (-).
  • Insert the power cable for the charger into the socket and switch the charger on.
  • At the end of the charging process, switch the charger off and pull the power cable out of the socket.
  • Remove the charger terminal clamps.
  • Close the cover on the positive terminal.
  • Close the hood.

WARNING

  • Never connect a charging cable or jump start cable directly to the 12 volt vehicle battery. Only use the connections in the engine compartment.
  • A highly explosive mixture of gases can form when charging batteries. Only charge the battery in well-ventilated areas.
  • A drained battery can freeze at temperatures around 32 ºF (0 ºC). Do not charge or use a frozen or thawed battery. If ice forms, the battery housing can crack and battery electrolyte fluid can leak, which increases the risk of an explosion and chemical burns.

    Contact an authorized Audi dealer or authorized Audi Service Facility for more information.

  • Do not connect or disconnect the charging cable while charging because this increases the risk of an explosion.

Tips

Read all of the manufacturer's instructions for the charger before charging the battery.
