the malfunction repaired.

ZA\ WARNING
Do not tow your vehicle if there is a malfunc-
tion in the electronic steering lock because
this increases the risk of an accident.
@ Tips
If the & or a indicator light only stays on
for a short time, then you may continue driv-
ing.

ALL wheel drive (quattro)
Applies to: vehicles with all wheel drive
The all-wheel drive system distributes the driving
power variably to the front and rear axle to im-
prove the driving characteristics. It works togeth-
er with selective wheel torque control, which can
activate when driving around curves > page 105.
The all-wheel drive system is designed for high
motor power. Your vehicle is exceptionally power-
ful and has excellent driving characteristics both
under normal driving conditions and on snow and
ice. Always read and follow safety precautions
oA.

ZA WARNING
— Even in vehicles with all wheel drive, you
should adapt your driving style to the cur-
rent road and traffic conditions to reduce
the risk of an accident.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not drive too fast because this in-
creases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane’” if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the motor RPM does not increase
suddenly when the vehicle begins hydro-
planing. Adapt your speed to the road condi-
tions to reduce the risk of an accident.

IY ett Tel -1
EH All-wheel drive: malfunction! Limited stabil-
ity. Please contact Service
Driving stability is reduced. Continue driving with
caution. Drive to an authorized Audi dealer or au-
thorized Audi Service Facility immediately.
Electronic Stabilization
Control
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations, such oversteering and understeering of
the vehicle, the drive wheels spinning, or the risk
of the vehicle tipping.
The brakes are applied or the motor torque is re-
duced in order to stabilize the vehicle.
The following stabilization functions are integrat-
ed into the ESC, among others:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak-
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal.
Noises will indicate when the system is working.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly.
EDL will switch on again automatically when con-
ditions have returned to normal.

Driving dynamic


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.
B Ss / B & 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.

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.
