Pier MU
A new vehicle must be broken in within the first
1,000 miles (1,500 km) so that all moving parts
work smoothly together, which helps to increase
the service life of the engine and other drive com-
ponents.
Do not drive higher than two-thirds of the maxi-
mum permitted engine RPM during the first 600
miles (1,000 km) and do not use full accelera-
tion. The engine can be increased RPM gradually
during the next 300 miles (500 km).

With plug-in hybrid drive, you can select between
the electric and combustion engine drive systems
or combine them > page 114, > page 111.
Recuperation
Applies to: vehicles with plug-in hybrid drive
The vehicle is able to recover energy by using “re-
cuperation”. The electric drive system operates
like a generator and converts a large portion of
kinetic energy into electrical energy that is stored
in the high-voltage battery. The vehicle is braked
during recuperation, which is similar to the en-
gine braking effect on a vehicle with a combus-
tion engine. This will happen automatically when
you press the brake pedal while driving in “D”
gear, or when you remove your foot from the ac-
celerator pedal.
When you press the brake pedal, recuperation is
used to brake the vehicle. The brakes will only be
activated if necessary. When driving normally,
114
this makes it possible to brake using only recu-
peration just before coming to stop and to lose
little energy and range from braking.
Settings options
You can set if recuperation should be adjusted to
be proactive*, for example, to the road.

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.

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 in the lug-
gage compartment under the cargo floor and
does not require any maintenance from the driv-
er.


ZX 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-

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.

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.
Charging the high-voltage battery
Introduction
Applies to: vehicles with plug-in hybrid drive
The following options are available to charge the
high-voltage battery:
131

High-voltage system


Charging method Charging cable

Charge with household and industrial alternat-
ing current (AC) sockets
Audi e-tron compact charging system > page 140

Charge at public alternating current (AC) charg-
ing stations

Charging station cable

Audi recommends using alternating current (AC)
to charge the high-voltage battery at industrial
sockets, charging stations, or a wallbox. This will
allow you to achieve higher efficiency and a con-
siderably shorter charging time when compared
to charging with a household socket.
Only charge at household sockets with the
Audi e-tron compact charging system under spe-
cial circumstances when it is not possible to
charge at an industrial alternating current (AC)
socket or at a public alternating current (AC)
charging station.
High-voltage batteries age over time, which re-
duces the available range. High-voltage batteries
can also age because of how they are used: fre-
quently charging the high-voltage battery com-
pletely accelerates the aging of the battery and
reduces the available range.
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

ZA WARNING
Short circuiting, electric shock, explosions,
fire, and severe burns can result from charg-
ing the battery incorrectly (for example by
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.
The components in the charging equipment
can trigger sparks, which can cause flamma-
ble or explosive fumes to ignite. To reduce
the risk of explosions, especially in garages,
make sure the Audi e-tron charging system
control unit is at least 19 inches (50 cm)
above the floor when charging.
— Never use the charging equipment with an
extension cord, a cable reel, a power strip,
or an adapter, for example, a travel adapter
or timer.
— Do not touch the contacts on the vehicle
charging port or charging equipment.
— Do not insert any objects in the vehicle
charging port or in the charging equipment.
— Always protect the sockets and connections
from water, moisture and other fluids.
— Only use the charging equipment provided
by the factory or the charging station cable.

CG) Note
— Severely draining the high-voltage battery
can damage it. Once a O mi (0 km) electric
range is displayed, charge the high-voltage
battery within two months. If the stationary
time is unknown with the electric range at 0
mi (0 km), charge the high-voltage battery
immediately. Even if the vehicle is not used,
the high-voltage battery charge level will
naturally reduce over time. To avoid a total
battery drain during long periods without
use (more than one year), charge the high-
voltage battery to the highest level possible
before discontinuing driving it.
— Make sure that you always use the correct
charging equipment for the country in
which it is being used. Contact an author-
ized Audi dealer or authorized Audi Service
Facility for more information.
