before and during the Stop phase, and deter-
mines if the engine stops and how long it re-
mains stopped. For example, if power usage is
high, the engine will not be stopped. Along with
other conditions, the following factors influence
the automatic engine start or stop:
— Environmental conditions (slopes, inclines, ele-
vation, temperature)
— Battery (charge status, temperature, power us-
age)
— Engine temperature
— Assist systems
— Driving behavior
Depending on the engine, the indicator light
may appear if the engine is not stopped.
Z\ WARNING
To reduce the risk of asphyxiation, never allow
the engine to run in confined spaces.
@) Tips
If you select the "D" or "N" selector lever posi-
tion in a vehicle with an automatic transmis-
sion after shifting into reverse, the vehicle
must be driven faster than 6 mph (10 km/h)

High-voltage system
High-voltage system
General information
Introduction
Applies to: vehicles with plug-in hybrid drive
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 motor, the high-voltage A/C
compressor, the high-voltage heater, the charg-
ing system and charging port, and the orange
high-voltage wiring.
The high-voltage battery is located on the vehicle
underbody in front of the rear axle 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.
— Gases that escape from the high-voltage
battery can be poisonous or flammable.
96
— 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 ve-
hicle to an authorized repair facility and
have it inspected.
— The electric drive motor can become very
hot during operation. Do not stop the vehi-
cle if there is oil, fuel residue or other flam-
mable substances under or next to the vehi-
cle.
Special considerations for the high-voltage
battery
Applies to: vehicles with plug-in hybrid drive
Please first read and note the introductory infor-
mation and heed the warnings > page 96.
All batteries age with use and over time. There
are things you should know about the care of the
high voltage battery that will help it keep giving
you good service and reliability over time. Please
read and keep the following information in mind
while you enjoy the performance and economy of
your vehicle.
— Be sure to charge the high voltage battery be-
fore leaving the vehicle parked and unused for a
longer period of time. Ideally the high-voltage >
Page 99 of 400
8V2012721BK
High-voltage system
battery should have a charge level between
40 % and 60 % when parked for a Long time.
If the battery charge level is below 3 %, never
park the vehicle for more than 21 days without
charging the high-voltage battery. Should you
have to park the vehicle for a long time, make
sure that the charge level is sufficient to help
prevent the battery from aging prematurely.
Frequent and consecutive charging of the high-
voltage battery when the charge level is above
98 % can also decrease the capacity of the
high-voltage battery. Make sure the charge lev-
el is below 98 % when you start the charging
process.
Should the vehicle be parked for longer than
2 days at temperatures below - 13 °F (-25 °C),
the high-voltage battery could freeze and not
be able to provide energy to the electric motor.
The battery will start working again, once it
warms up. The battery can be warmed up when
the outside temperature rises or when the vehi-
cle is garaged appropriately. The battery will al-
so warm up when being used (switching on the
air conditioner, the heater or by driving the ve-
hicle). Should you have to park your vehicle at
very low temperatures for longer than 1 day,
make sure that the high-voltage battery does
not freeze by parking the vehicle in a garage
that is heated or protected from the outside
temperature.
The high-voltage battery can be damaged and
the capacity can be decreased when the vehicle
is parked for longer than 24 hours when the
ambient temperature is higher than 118 °F
(48 °C). Always make sure that the high-voltage
battery is not exposed to temperatures above
118 °F (48 °C) for a long time.
Never park the vehicle in areas that are likely to
be flooded, such as beaches or river banks, and
never drive the vehicle in WATER, on flooded
roads or through water that is higher than the
bottom of the vehicle body. The high-voltage
battery, along with other vehicle components,
can be damaged severely if the high-voltage
battery is exposed to open water especially for
a longer time. However, you can drive through
water on roads under certain conditions
=> page 90.
Failure to heed any of these requirements can
age the battery prematurely and lead to a perma-
nent decrease of the high-voltage battery’s ca-
pacity.
G@) Tips
Always make sure that the high-voltage bat-
tery is not exposed to extremely low and high
temperatures as well as to water especially
for a longer time. Failure to protect and care
for the high voltage battery can lead to seri-
ous damage and/or a decrease of the capacity
void coverage under the New Vehicle Limited
Warranty.
Vehicle transport
