High-voltage system


Charging method Charging cable

Charge with household and industrial alternat-
ing current (AC) sockets
Audi e-tron compact charging system > page 128

Charge at public alternating current (AC) charg-
ing stations

Charging station cable

Audi recommends using alternating current (AC)
to charge the high-voltage battery at industrial
sockets, charging stations, or a wallbox. This will
allow you to achieve higher efficiency and a con-
siderably shorter charging time when compared
to charging with a household socket.
Only charge at household sockets with the
Audi e-tron compact charging system under spe-
cial circumstances when it is not possible to
charge at an industrial alternating current (AC)
socket or at a public alternating current (AC)
charging station.
High-voltage batteries age over time, which re-
duces the available range. High-voltage batteries
can also age because of how they are used: fre-
quently charging the high-voltage battery com-
pletely accelerates the aging of the battery and
reduces the available range.
Charging time
The duration of the charging process may vary
based on the following factors:
— Sockets being used (household or industrial
sockets)
— Country-specific system voltage, current
strength and number of available phases
— Household connection
— The value set for the charging power level on
the Audi charging system control unit
— Fluctuations in the system voltage
— The temperature outside the vehicle
— The temperature of the high-voltage battery
and the Audi charging system control unit.
— Settings for the climate control inside the vehi-
cle
— Current capacity of the charging connector
— Whether the ignition is on or off

ZA WARNING
Short circuiting, electric shock, explosions,
fire, and severe burns can result from charg-
ing the battery incorrectly (for example by
disregarding general safety precautions, using
unsuitable or damaged sockets and charging
cables, or charging with unsuitable electrical
equipment) and can lead to serious and fatal
injuries.
— Do not charge using sockets/electrical
equipment that is clearly damaged or instal-
led incorrectly.
— Never use charging equipment that is clearly
damaged and/or dirty. Check the charging
equipment for damage before every use.
— Never modify or repair any electrical compo-
nents, especially the high-voltage system.
— Never charge in areas at risk for explosions.
The components in the charging equipment
can trigger sparks, which can cause flamma-
ble or explosive fumes to ignite. To reduce
the risk of explosions, especially in garages,
make sure the Audi e-tron charging system
control unit is at least 19 inches (50 cm)
above the floor when charging.
— Never use the charging equipment with an
extension cord, a cable reel, a power strip,
or an adapter, for example, a travel adapter
or timer.
— Do not touch the contacts on the vehicle
charging port or charging equipment.
— Do not insert any objects in the vehicle
charging port or in the charging equipment.
— Always protect the sockets and connections
from water, moisture and other fluids.
— Only use the charging equipment provided
by the factory or the charging station cable.

High-voltage system


LED on the charging unit Meaning

Off
Vehicle charging system is in sleep mode. A timer may be active,
but charging has not started yet.

Charging process is interrupted.

Pulsing The high-voltage battery is charging.

Green Flashing A timer is active, but charging has not started yet.

On High-voltage battery charging process is completed.

On
Yellow
When using the Audi charging system, make sure the power
plug is inserted in the power socket > page 128. No power sup-
ply was recognized even though the charging cable is plugged
in. Have the power supply or power supply system inspected.
When using the Audi charging system, check the status displays
on the unit > table on page 129. See an authorized Audi dealer
or authorized Audi Service Facility for assistance if necessary.

Flashing
The vehicle is not secured from rolling away. Check if “P” is se-
lected and the parking brake is set. If the LED continues to
flash, see an authorized Audi dealer or authorized Audi Service
Facility for assistance.

Red On

The charging connector may not be able to lock correctly in the
vehicle charging port. Check if the charging connector is insert-
ed correctly. Remove the charging connector and plug it in the
charging port again, or use a different charging station. If the
LED stays turned on, there is a malfunction either in the vehicle
charging system or at the power source. See an authorized Audi
dealer or authorized Audi Service Facility for assistance if neces-
sary.


The outside temperature is too low or too high.

@ Tips
The operation status indicated by the LED on
the charging unit are is displayed in the in-
strument cluster Es.
Setting the timer

Introduction
Configuring the timer
> To set a timer, select > in the line for the de-
sired timer.
> If the timer should be set one time, select Indi-
vidual timer. If the timer should be set to re-
peat, select Repeat timer.
> Set a preferred charging time if desired, for ex-
ample to use off-peak power rates.
> To also activate the climate control with a tim-
er, select CD.

Use a timer to set at what departure time your
vehicle should be fully charged. A timer can ei-
ther be set one time or to repeat at the selected
times. You can also specify if your vehicle should
be heated or cooled to the temperature set in the
climate control system. You can turn on multiple
timers at the same time.

Wheels


AN WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.

() Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.
— Do not install and use snow chains if there is
a malfunction in the air suspension*, be-
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo-
nents can be severely damaged.
@ Tips
When using snow chains, it may be advisable
to limit the ESC > page 116.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 284.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 275, fig. 170.
For example: Tread wear 200, Traction AA, Tem-
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern-
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band C. Those grades represent the tire's
ability to stop on wet pavement as measured un-
der controlled conditions on specified govern-
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
SA.
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
