High-voltage system

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 life-
threatening. Touching a damaged high-volt-
age 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.

104

— 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.
@) Note
The high-voltage system can be damaged if
the vehicle underbody comes into contact
with the ground. Immediately drive your vehi-
cle to an authorized repair facility and have it
inspected.
Vehicle transport
This section contains information you should
know about transporting your vehicle.

A lithium-ion high-voltage battery system equip-
ped in your vehicle has passed test 38.3 in ac-
cordance with the UN Tests and Criteria hand-
book and is manufactured in accordance with a
quality management program. The vehicle may
be transported with the high-voltage battery in-
stalled as conventional class 9 hazardous materi-
als without additional official authorization for
air and sea shipment (current law IATA-DGR and
IMDG code 01.01.2018).

Accessories and technical changes

Technical Modifications
Interference with electronic components, their
software, the wiring, and data transfer may cause
malfunctions. Because of the way electronic com-
ponents are interconnected, such malfunctions
can also impair systems that are not directly in-
volved. This means that you risk both a substan-
tial reduction in the operational safety of your ve-
hicle and increased wear of vehicle components.
Some convenience functions, such as the conven-
ience turn signal function, individual door open-
ing function, and displays, can be reprogrammed
using special workshop equipment. If functions
are reprogrammed, the information and descrip-
tions about these functions in this Owner's Man-
ual may no longer apply to the changed func-
tions. Audi recommends that an authorized Audi
dealer or authorized Audi Service Facility perform
and verify any reprogramming procedures.

Z\ WARNING
Maintenance procedures, repairs, or technical
modifications that are performed incorrectly
increase the risk of an accident and can lead
to serious injuries.

Z\ WARNING
The engine/motor compartment in any motor
vehicle is a potentially dangerous area and can
cause serious personal injury.
— Always use extreme caution when doing any
work in the motor compartment. Always fol-
low commonly accepted safety practices and
use common sense. Never risk personal in-
jury.
— Never perform any work in the motor com-
partment unless you know exactly how to
carry out the job and have the correct tech-
nical information and the correct tools.
— If you are uncertain about what to do, have
the work performed by an authorized Audi
dealer, an authorized Audi Service Facility,
or another qualified workshop. Serious per-
sonal injury may result from improperly per-
formed work.

CG) Note
— Maintenance procedures, repairs or techni-
cal modifications that are performed incor-
rectly can cause damage to the vehicle, such
as corrosion.
— If emergency repairs must be performed,
take your vehicle to an authorized Audi deal-
er or authorized Audi Service Facility as soon
as possible.
— Audi is not liable for damage to the vehicle
resulting from failure to comply with these
guidelines.
(@) For the sake of the environment
— Regular maintenance can help protect the
environment.
— Technical modifications to the vehicle may
have a negative affect on energy use.
@) For the sake of the environment
Undeployed airbag modules and pretension-
ers are classified as Perchlorate Material —
special handling may apply, See www.dtsc.ca.
gov/hazardouswaste/perchlorate. When the
vehicle or parts of the restraint system includ-
ing airbag modules and safety belts with pre-
tensioners are scrapped, all applicable laws
and regulations must be observed. Your au-
thorized Audi dealer is familiar with these re-
quirements and we recommend that you have
your dealer perform this service for you.
G) Tips
Because of your vehicle's aluminum body de-
sign, all service and repair procedures affect-
ing the body should be performed by an au-
thorized Audi dealer or authorized Audi Serv-
ice Facility, who will perform the work accord-
ing to Audi factory specifications. Only Audi
Genuine Parts are used when Audi experts
perform repair or service procedures. Failure
to use Audi Genuine Parts or Audi Genuine Ac-
cessories or performing repairs incorrectly
may result in severe vehicle damage, such as
corrosion.
