ZA\ WARNING
If the charging equipment is not secured or
positioned correctly, it can slide out of place
and endanger vehicle occupants when brak-
ing, when changing directions, or in a colli-
sion.
— Only transport the charging equipment in
the front storage compartment and never
unsecured or in the passenger compart-
ment.

() Note
Always lift or carry the Audi charging system
as one unit and never by the cables.

The Audi e-tron compact charging system can be
used for charging with a household or industrial
socket. Depending on the country and the vehicle
equipment, the following accessories may be
available:
@ Control unit
@ Vehicle cable with vehicle charging connector
@) Power cable with power plug for household
sockets
@ Power cable with power plug for industrial
sockets
The vehicle cable is securely connected to the
control unit. The power cable is plugged into the

— Insert the plug into the socket.
— Plug the vehicle charging connector into the ve-
hicle charging port.
— The charging process e will start automatically.
— Once the charging process has completed, un-
lock the vehicle and remove the vehicle charg-
ing connector from the vehicle charging port.
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.
The vehicle has a minimum battery charging ca-
pacity of 880 W. Therefore, if the network volt-
age is less than 200 V, charging using a house-
hold socket will only be possible if the charging
power level is set to 100%. Otherwise, the charg-
ing process will not start.
Before charging, always check if the charging
power setting that was selected last is still suita-
ble.
— To set the charging power level, press and hold
the ® button © ® fig. 87 for at least two sec-
onds.
After the charging power level is set, the status

been restored to the control unit. If a self
test is successful, all indicator lights will il-
luminate green for two seconds.
— The Audi e-tron compact charging system is

age of 120 V/240 V. If your socket has a dif-
ferent voltage, contact and authorized Audi
dealer or authorized Audi Service Facility.
— If your Audi e-tron compact charging sys-
tem has a fixed connection, meaning can be
connected directly to the power supply

4KE012721BF
High-voltage system


— Only change cables in a dry environment.
— The Audi charging system may only be used
as a complete unit consisting of the power
cables, the control unit, and the vehicle ca-
ble. Depending on the country, the total
length of the power cable, control panel and
vehicle cable may be restricted, for example
to 24.6 feet (7.5 m) in the USA. Audi recom-
mends using only cables approved by Audi.
@) Tips
The power cable with the power connector for
industrial sockets and the Audi charging sys-
tem control unit are designed to work togeth-
er. Changing the power cable to another con-
nector type may reduce the available charging
power of the entire system. Limitations on
the ability to transfer power (current capacity)
depending on the phase and the number of
available phases may affect the available
charging power.

Securing the Audi charging system
> First insert the control unit in the bottom tabs
on the wall mount clip and then into the upper
tabs.
> Push the control unit in the direction of the ar-
row toward the rear > fig. 89 and let it lock into
place.
> Wrap the excess length of cable around the
charging connector mount @ when you are not
charging the high-voltage battery.
> Plug the power cable into the socket (2).
> After charging, you can hook the vehicle charg-
ing connector to the charging connector mount

Locking and unlocking the Audi charging
system
> You can lock or unlock the Audi charging sys-
tem using the key provided by turning it to the
lock position @) or the unlock position 6).
Removing the Audi charging system
> Remove the power cable connector from the
socket (2).
> Unwind the cable from the charging connector
mount (@).
> To loosen the control unit from the bracket,
push the locking mechanism @) upward.

Trailer towing

Trailer towing
Driving with a trailer
er else)
Your vehicle is primarily intended for transport-
ing people and luggage. However, if you drive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg-
ulations.
Driving with a trailer affects the vehicle's energy
usage, performance, and wear. It also requires
higher concentration from the driver.

ZA\ WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Trailer hitch

Only use a trailer hitch with a removable ball
hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle, the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any modifications to the brake system.
Check regularly if the trailer hitch is securely
mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol-
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.

ZA WARNING
— Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trailer
hitch. The vehicle was not designed for
these types of trailer hitches. The trailer

126

hitch can malfunction and the trailer can
break off from the vehicle.
— If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in-
creases the risk of an accident.
—To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount-
ed.
Operating instructions
Towing capacity

The permitted towing capacity must not be ex-
ceeded under any circumstances > page 291.
You can drive up larger inclines if you are not us-
ing the maximum towing capacity.
Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head must
not be exceeded.
For driving safety, Audi recommends always us-
ing
the maximum permitted tongue weight, but
do not exceed this weight. Distributing the cargo
in the trailer correctly will help to achieve this
weight. Having the tongue weight too low affects
the vehicle's handling.
You can determine the tongue weight using a
tongue weight scale, a bathroom scale, or a pub-
lic weigh station, for example.
The permitted tongue weight of your vehicle can
be found in the vehicle documentation or in
=> page 291.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. Load the trailer based
on the following criteria as much as possible:
— Store objects in the vehicle luggage compart-
ment, if possible. The vehicle should always
carry the heaviest possible load and the trailer
should have the lightest possible load.
— Distribute the load in the trailer so that the
heavy objects are as close to the axle as possi-
ble.
