The function should only be activated if the
charging cable is part of the charging station.
Otherwise, your charging cable could be sto-
len.
Setting the charging target
You can set the charging target, meaning you can
set the maximum charge level to which the high-
voltage battery should be charged. The charging
target can be set between 50% and 100%. For
daily usage, Audi recommends setting the charg-
ing target at 80%. This can extend the service life
of the high-voltage battery. For long trips, Audi
recommends setting the charging target to
100% to achieve the highest possible range.

VEHICLE > Charging & Efficiency > Charging.
> When the timer is displayed, swipe your finger
on the display toward the right.
> Press on the right section of the battery charge
level display.
> Set the desired charging target.
The charging target that is set will be stored and
used in all locations where you have not defined
specific charging settings. If you are charging at
an address where you have defined specific
charging settings > page 116, Advanced charg-
ing settings, the charging target that is set will
be stored in the advanced charging settings and
used.
G) Tips
If you set the charging target lower than the
current battery charge level while charging,
then the charging process will be canceled. If
you set the charging target above the current
battery
charge level again, then the charging
process will resume. This does not apply if you
are charging at a charging station, where you
have authenticated yourself manually. If this
is the case, authenticate yourself again at the
charging station.

Grounding instructions
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 and a
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.
ZA 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.

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.
