Driving

When you press the brake pedal, recuperation is
used to brake the vehicle. The brakes will only be
activated if necessary. When driving normally,
this makes it possible to brake using only recu-
peration just before coming to stop and to lose
little energy and range from braking.
Setting options
You can set how strongly the vehicle should be
braked by recuperation while coasting.
> Applies to: MMI: Select on the home screen:
VEHICLE > Charging & Efficiency > Efficiency
assist > Recuperation.
Automatic: the recuperation braking effect is ad-
justed proactively* to the route or vehicles driv-
ing ahead, for example. You can temporarily ad-
just the braking effect by selecting a recuperation
level with the shift paddles.
Manual: the recuperation braking effect is con-
trolled manually. You can select a recuperation
level using the shift paddles.
Settings using the shift paddles:
>» Select © for a stronger braking effect.
> Select (+) for a weaker braking effect.

ZA WARNING
In certain situations, the recuperation may
brake proactively. However, the recuperation
braking effect is limited. Always be ready to
brake to reduce the risk of an accident.
G) Tips
If the ESC is limited or switched off, automat-
ic recuperation is not available and will not
brake.

Range potential: the value indicates an addition-
al amount of distance that can be gained by turn-
ing off certain convenience functions. The con-
venience functions with high energy usage are
listed on
the display.
Range mode: to maximize the current range, you
can use the button to switch the vehicle to a
mode with less energy consumption. This will re-
duce the drive system power and the maximum
speed. This can also turn off certain energy con-
sumers. You can exit this mode by either pressing
the button again, pressing the Audi drive select*
button, or switching off the ignition.
G) Tips
— The range can also be displayed in the in-
strument cluster in the on-board computer.
— The range that is indicated is based on the
previous and predicted consumption values.
For example, this may influence the naviga-
tion route guidance or activated conven-
ience functions.
Vehicle sound
The electric drive system generates considerably
less noise than a combustion engine. An artificial
engine sound is generated when driving electri-
cally so that the vehicle can be heard from the
outside when driving. The vehicle sound auto-
matically fades out at higher speeds when the
sounds from the tires and wind start increasing. >

General information
Introduction
All work done on the high-voltage system must
only be performed by certified high-voltage tech-
nicians at authorized Audi dealers or authorized
Audi Service Facilities in accordance with Audi
guidelines.
The high-voltage system is composed of the fol-
lowing high-voltage components, among other
things: the high-voltage battery, the power elec-
tronics, the electric motors, the high-voltage A/C
compressor, the high-voltage heater, the charg-
ing system and charging port as well as the or-
ange high-voltage wiring.
The high-voltage battery is located on the vehicle
underbody and does not require any maintenance
from the driver.


ZA WARNING
The voltage in the high-voltage system is high
enough to cause fatal injuries. Touching a
damaged high-voltage component can result
in a fatal electric shock. The components in
the high-voltage system are marked with a
warning label which warns against the high-
voltage.
— The voltage level in the high-voltage system
is still dangerous and potentially life-threat-
ening when the ignition is switched off.
— Never perform work on the orange high-
voltage cables or on other high-voltage
components. Only authorized repair facili-

ties that are certified may perform work on
the high-voltage system.
— Never damage, alter or remove the orange
high-voltage cable or disconnect it from the
high-voltage system.
— Never perform any work using cutting, shap-
ing or sharp-edged tools or heat sources
near the high-voltage system and high-volt-
age cables.
— Gases that escape from the high-voltage
battery can be poisonous or flammable.
— Damage to the high-voltage battery could
cause the high-voltage battery to leak im-
mediately or in the future, and poisonous or
flammable gases could escape. Do not in-
hale the gases!
— Do not expose yourself to any leaking fluids
and do not come into contact with them.
— The high-voltage battery electrolyte fluid is
caustic. If electrolyte fluid comes into con-
tact with the skin, flush the affected area for
at least 15 minutes with clean water. Then
wash the affected area with soap. Have the
affected area examined by a medical profes-
sional.
— In the event of a technical emergency, in-
form the responders that the vehicle is
equipped with a high-voltage battery.

High-voltage system

Charging at household and industrial sockets
or at public charging stations with
alternating current (AC)
The vehicle's high-voltage battery can be charged
with alternating current (AC) via the charging
port () on the driver's side. Depending on the ve-
hicle equipment, there may be a second charging
port © on the front passenger's side. Both
charging ports have the same charging power.
You can use whichever charging port is more con-
venient for your charging setup. When using one
charging port, the opposite charging port is
locked.
Quick charging at public direct current (DC)
charging stations
The vehicle’s high-voltage battery can be charged
at a direct current (DC) charging station via the
charging port on the driver's side (S). There is a
significant decrease in charging time. The charg-
ing cable used may be a maximum of 98 feet (30
m).
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
Important safety precautions
