a ing the battery
Fig. 166 Engine compartment: connectors for a charger or
jump start cables
Note the safety precautions > page 214, General
information, > A\ in Battery general informa-
tion on page 223 and > /\.
Requirement: only use chargers with a maximum
charging current of 14.8 volts. The battery ca-
bles remain connected.
The battery is located in the engine compart-
ment. The ground point ©) is always located on
the vehicle body.
> Switch off the ignition and all electrical equip-
ment.
> Open the hood > page 215.
> Press the release lever on the positive terminal
and fold the cover upward > fig. 166.
> Clamp the charger terminal clamps to the jump
start pins according to the instructions. (Pin un-
der the cover = “positive”).
> Insert the power cable for the charging device
into the socket and switch the device on.
> At the end of the charging process, switch the
charger off and pull the power cable out of the
socket.
» Remove the charging device terminal clamps.
> Close the cover on the positive terminal.
> Close the hood > page 215.
ZX WARNING
— Never connect the charging cable directly to
your vehicle battery. Only use the connec-
tions in the engine compartment
=> page 225.
— 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.
G) Tips
Read all of the manufacturer's instructions
for the charger before charging the battery.

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.

Emergency assistance
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.
ZA\ WARNING
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). If the vehicle bat-
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 214.
— Handling the jump start cables incorrectly
may cause the vehicle battery to explode
and lead to serious injuries.
©) 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.
aoe Teall]
Both jump start cables must be connected in the
correct order.
