Checking and Filling
Battery
eae mee eles)
Because of the complex power supply, all work on
batteries such as disconnecting, replacing, etc.,
should only be performed by an authorized Audi
dealer or authorized Audi Service Facility > A\.
Multiple batteries with different technologies
may be installed in your vehicle:
— Vehicle battery (for example, for starting the
engine, basic power supply) > page 315, Lead
battery or > page 316, Other battery types
— Auxiliary battery (for example, for recuperation
or optional equipment) > page 316, Other bat-
tery types
— Applies to: plug-in hybrid drive: High-voltage
battery (for example, for electric driving)
=> page 96.
Not running the vehicle for long periods of
time
The battery will gradually drain if the vehicle
does not run for long periods of time. To ensure
that the vehicle can still be started, the electrical
equipment will be reduced or switched off
=> page 82. Some convenience functions, such as
interior lighting or power seat adjustment, may
not be available under certain circumstances.
These convenience functions will be available
again once you switch the ignition on and start
the
engine.
Even when electrical equipment is switched off,
the equipment can still drain the battery if the
vehicle is not driven for long periods of time.
Deep draining results in a chemical reaction that
destroys the inside of the battery. The battery
must be charged every month to prevent this
= page 316. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.
Winter operation
Cold weather places higher demands on the bat-
tery. This results in reduced starting ability. Have
the battery checked by an authorized Audi dealer
or authorized Audi Service Facility before cold
weather begins.
ZA WARNING
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Never connect the charging cable or jump
start cable directly to your vehicle battery.
Only use the connections in the engine com-
partment > page 316.
Z\ WARNING
California Proposition 65 Warning:
— Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive problems.
Wash hands after handling.
@) Note
If the vehicle will be parked for long periods
of time, protect the battery against the cold
so that it will not be destroyed by “freezing”
= page 316, Charging the battery.

cal professional.
@ Note
Components must not be connected to the
battery terminals and wires on these battery
types because this increases the risk of dam-
age, for example due to overvoltage.

Note the safety precautions > page 304, General
information, > /\ in Battery general informa-
tion on page 315 and > /\.
Plug-in hybrid drive: > page 365.
Requirement: only use chargers with a maximum
charging current of 14.8 volts. The battery ca-
bles remain connected.
Depending on the engine, the battery is located
in the engine compartment or in the luggage
compartment. For vehicles with the battery in
the luggage compartment, a jump start point
that is also used for battery charging is located in
the engine compartment. The battery is always
charged in the engine compartment. The ground
point ©) is always located on the vehicle body.

ZA WARNING
— Applies to: vehicles with jump start connec-
tions in the engine compartment: The
charging cable must never be connected di-
rectly to the vehicle battery. Only use the
connections in the engine compartment
=> page 316.
— 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.

the cleaning solution for the windshield and the
headlight washer system* > page 307, fig. 248.
The reservoir capacity can be found in

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.
Messages
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.

Emergency situations
Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec-
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
@) Note
Vehicles with an automatic transmission can-
not be started by pushing or towing.
Jump starting
If needed, the engine can be jump started by an-
other vehicle battery.
Applies to: vehicles with plug-in hybrid drive: The
connection points for the jump start cable are
different > page 365.
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.
A WARNING
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). If the vehicle bat-
364
tery is frozen, it must be thawed before con-
necting the jump start cables. If it is not,
the risk of an explosion and chemical burns
increases. After jump starting the vehicle,
drive to an authorized Audi dealer or author-
ized Audi Service Facility immediately to
have the vehicle battery checked.
— Read the warnings when working in the en-
gine compartment > page 304.
— Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries.
— Applies to: vehicles with plug-in hybrid
drive: You must not give a jump start with
your vehicle. This could cause significant
damage to the electrical system in your ve-
hicle > page 365.
— Applies to: vehicles with the battery in the
engine compartment: To reduce the risk of
chemical burns, do not bend over the vehicle
battery.
@) Note
Jump start cables can cause considerable
damage to the vehicle electrical system if
they are connected incorrectly.
G@) Tips
— There must be no contact between the
vehicles, or else voltage could flow when
connecting the positive terminal and drain
the vehicle battery of the vehicle providing
the jump start.
— The drained vehicle battery must be con-
nected correctly to the electrical system.
— Switch off electrical equipment that is not
needed.

Towing with a tow truck
General hints
Your Audi requires special handling for towing.
The following information is to be used by com-
mercial tow truck operators who know how to op-
erate their equipment safely.
— Never tow your Audi. Towing will cause dam-
