High-voltage system

If the driver's door is opened while the ignition is
switched off, the current battery charge level and
the high-voltage battery range will be displayed
in the instrument cluster. If charging is in prog-
ress, the remaining charging time will also be
displayed.
Immediate charging and timer charging
You can switch between the immediate charging
@ and charging timer @) options during the
charging process if a charging timer is set
=> page 136. Press the corresponding button to
do this.

— Put the cap back on the charging port.
— Close the charging port door.
— Disconnect the charging cable from the power
supply if necessary or return it securely to the
charging station.
— Install the protective caps on the charging ca-
ble again.
— If you are transporting the charging cable in
the vehicle, store it securely > page 139.
If the charging connector cannot be removed,
you must unlock it manually > page 137.
If you cannot disconnect the charging connector
from the charging station, authenticate yourself
again at the charging station and then try again
to disconnect the charging connector. If you still
cannot disconnect the charging connector from
the charging station, contact the charging sta-
tion operator.

A WARNING
— Do not disconnect the charging cable from
the socket or the vehicle charging port while
the vehicle is charging. End the charging
process before removing the charging cable
from the socket in order to reduce the risk of
damaging the connector contacts from
sparks.
—If the charging unit is damaged, do not
charge using the charging port to reduce the
risk of injury.
— If the charging unit is damaged or the
charging port door cannot close or is miss-
ing, drive immediately to an authorized Audi
dealer or authorized Audi Service Facility
and have the malfunction corrected to re-
duce the risk of injury.
() Note
If you drive with the charging unit open, both
the charging port door and the electronics in-
stalled behind it could be damaged. Check
each time after charging if the port door is
locked before you start driving the vehicle.
@) Tips
— If the parking brake is set, it could create
noises when the charging connector is con-
nected.
— Remove ice and snow in the charging unit
using a hand brush and solvent-free deicing
spray.
— The vehicle radio and TV systems may have
limited reception when charging the vehicle.

Audi charging systems must be grounded. If it
should malfunction or break down, grounding
provides a path of least resistance for electric
current to reduce the risk of electric shock. Audi
charging systems are equipped with a cord hav-
ing an equipment grounding conductor anda
grounding plug. The plug must be plugged into
an appropriate outlet that is properly installed
and grounded in accordance with all local codes
and ordinances.

Z\ WARNING
Improper connection of the equipment-
grounding conductor is able to result in a risk
of electric shock. Check with a qualified elec-
trician or serviceman if you are in doubt as to
whether the product is properly grounded. Do
not modify the plug provided with the product
— if it will not fit the outlet, have a proper out-

let installed by a qualified electrician.

Adjusting the charging power level
The control unit automatically recognizes the
voltage and the available current strength. You
can set whether you would like to charge with full
or reduced charging power. The last setting that
was selected will be saved and used again the
next time the vehicle is charged. If multiple
items are connected to the power circuit, the
charging current may be reduced when charging
at a power outlet. This can help to prevent the
electrical equipment from overheating.
