WARNING
– Never use charging equipment that is un-
suitable, visibly damaged, and/or dirty.
Check the charging equipment for damage
before every use.
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.
– 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 ðpage 251.
– A highly explosive mixture of gases can form
when charging batteries. Only charge the
battery in well-ventilated areas.
Messages
The following messages may appear, depending
on the vehicle equipment:
– 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 fluid can leak, 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.
Please add washer fluid
Fill the washer fluid for the windshield washer
system and the headlight washer system* when
the ignition is turned 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 result in vehicle dam-
age.
– Leave the hood open while the 12 volt vehi-
cle battery is charging. If the hood is closed,
it could cause an electrical short circuit,
which increases the risk of fire.
