High-voltage system

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:

Charging method Charging cable

Charge with household and industrial alternat-
ing current (AC) sockets
Audi e-tron compact charging system > page 144

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
Important safety precautions
Applies to: vehicles with plug-in hybrid drive

Z\ 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,

Checking and Filling


AN WARNING
— Never connect a charging cable or jump
start cable directly to the 12 Volt vehicle
battery. Only use the connections in the en-
gine compartment > page 286.
— A highly explosive mixture of gases can form
when charging batteries. Only charge the
battery in well-ventilated areas.
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). Do not charge or
use a frozen or thawed battery. If ice forms,
the battery housing can crack and battery
electrolyte can leak out, which increases the
risk of an explosion and chemical burns.
Contact an authorized Audi dealer or author-
ized Audi Service Facility for more informa-
tion.
— Do not connect or disconnect the charging
cable while charging because this increases
the risk of an explosion.


@) Tips
Read all of the manufacturer's instructions
for the charger before charging the battery.
Windshield washer
system

B4M-0135,

Fig. 188 Engine compartment: washer fluid reservoir cap
Follow the safety precautions > page 274, Gener-
al information.
The windshield washer reservoir > contains the
cleaning solution for the windshield and the
headlight washer system > fig. 188, > page 277.
The reservoir capacity can be found in
=> page 342.
To reduce the risk of lime scale deposits on the
spray nozzles, use clean water with low amounts
of calcium. Always add window cleaner to the wa-
ter. When the outside temperatures are cold, an
anti-freezing agent should be added to the water
so that it does not freeze.
Message
gS Please add washer fluid
Fill the washer fluid for the windshield washer
system and the headlight washer system* when
the ignition is switched off.
() Note
—The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions and the climate. A concentration
that is too high can lead to vehicle damage.
— Never add radiator anti-freeze or other addi-
tives to the washer fluid.
— Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint.
Service interval display
The service interval display detects when your ve-
hicle is due for service.
The service interval display works in two stages:
— Inspection or oil change reminder: after driv-
ing a certain distance, a message appears in the
instrument cluster display each time the igni-
tion is switched on or off. The remaining dis-
tance or time is displayed briefly.
— Inspection or oil change due: if your vehicle
has reached an inspection or oil change interval
or both intervals at the same time, the mes-
sage Inspection due! or Oil change due! or Oil
change and inspection due! appears briefly af-
ter switching the ignition on or off.
Checking service intervals
You can check the remaining distance or time un-
til the next oil change or next inspection in the
Infotainment system.
Applies to: MMI: Select on the home screen: VE-
HICLE > Settings & Service > Service intervals.

Emergency assistance

To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment > page 100.
> Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it in the MMI
=> page 308.
> The wheel bolt tightening specification must be
90 ft lbs (120 Nm). Have it checked as soon as
possible with a torque wrench. Drive carefully
until then.
> Have the faulty wheel replaced as quickly as
possible.
Space-saving spare tire
Applies to: vehicles with space-saving spare tire (compact
spare tire)
The spare tire is intended for short-term use only.
Have the damaged tire checked and replaced if
necessary by an authorized Audi dealer or author-
ized Audi Service Facility as soon as possible.
There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the spare tire from an-
other type of vehicle.
The compact spare tire is located in the luggage
compartment under the cargo floor cover
> page 316.
The tire pressure must be 61 PSI (420 kPA).
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
322
If you have to drive with snow chains and a front
tire fails, mount the spare tire in place of a rear
tire. Install the snow chains on the rear tire that
you removed, and install that in place of the
front tire that failed.

ZA\ WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible.
— Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
— To reduce the risk of an accident, avoid hard
acceleration or braking and driving fast
around curves with the compact spare tire.
— To reduce the risk of an accident, never drive
with more than one compact spare tire.
— Normal summer or winter tires must not be
mounted on the compact spare wheel rim.

Jump starting
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
If the engine does not start because the vehicle
battery is drained, you can jump start your vehi-
cle using another vehicle. Jump start cables are
needed to do this.
Both vehicle batteries must have 12 V nominal
voltage. The voltage capacity (Ah) of the vehicle
battery that is giving power must not be less
than the capacity of the drained vehicle battery.
Jump start cable
Only use a jump start cable with a large enough
diameter. Note the manufacturer's specifica-
tions.
Only use a jump start cable with insulated termi-
nal clamps.
Positive cable - usually red.
Negative cable - usually black.
