2021 AUDI E-TRON warning

Driving dynamic

Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Power steering
The ESC can also support vehicle stability
through steering.

ZA\ WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
can affect driving stability and increase the
risk of a collision.
— As the vehicle load increases, especially the
roof load, the vehicle's center of gravity also
increases along with the risk of the vehicle
tipping. To reduce the risk of an accident, al-
ways adapt your driving style to the current
conditions and avoid sudden driving maneu-
vers.

@) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead toa
reduction in motor power.
106
— You may hear noises when the systems de-
scribed are working.
The So button (or #, depending on the model)
for controlling the ESC is located in the center
console, in front of the selector lever. The ESC is
automatically switched on when the ignition is
switched on.
Limiting ESC
In some situations, it may make sense to limit
the stabilizing function of the ESC so that the
wheels can spin, for example to rock a vehicle to
free it when it is stuck or to drive with snow
chains. The ESC can also be limited to provide
more sporty driving characteristics with fewer
stabilizing corrective actions.
—To limit the ESC, press the 0 button briefly.
The B indicator light will turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
light turns off.
Depending on the Audi drive select mode that is
selected, one of the following ESC modes will be
selected automatically:
— sport - this mode is designed for driving ona
level surface. It is used in all Audi drive select
modes except offroad.
— offroad - this mode is suited for driving offroad
and is designed for uneven terrain or loose
ground. If you select the offroad Audi drive se-
lect mode, the offroad ESC mode will be auto-
matically used.
Switching off ESC
For a more active control of the vehicle where the
stabilizing functions of the ESC cannot intervene,
the ESC can be switched off.
— To switch off the ESC, press and hold the Sor
button for more than three seconds. The B
and Ea indicator lights turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
lights turn off.

ZA WARNING
— When the ESC is switched off or limited,
there will be no vehicle stabilization or it will
be limited. The driving wheels could spin
and the vehicle could swerve, especially on
slick or slippery road surfaces. When there is
a heavy vehicle load and sudden driving ma-
neuvers, it may not be possible to prevent
the vehicle from tipping under certain cir-
cumstances, which increases the risk of an
accident.
— Because of the increased risk of an accident,
only drive with the ESC switched off or limit-
ed when it is necessary. Reactivate the ESC
as soon as possible.

@) Tips
— If you select the Audi drive select* offroad
mode, hill descent assist will switch on.
— If the ESC is limited, switched off, or mal-
functioning, systems with an automatic
braking intervention function may not be
fully available.
— If malfunctions occur in other systems or
certain driver assist systems are active, the
ESC must be switched on by the system. The
ESC
may switch on automatically and can-
not be operated with the button.
BA fs i BB & Stabilization control (ESC/
ABS): malfunction! See owner's manual
There is a malfunction in the ABS or EDL. This al-
so causes the ESC to malfunction. The brakes still
function with their normal power, but ABS is not
active.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
Other indicator lights
ira blinks while driving, the ESC is actively reg-
ulating. Operating noises may occur. If the indi-
cator light stays on, the ESC has been switched
off due to system needs. The indicator light turns
off when the system is fully functional.

High-voltage system
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.

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

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.

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.
