For
the
sake
of
the
environment
Because
of
the
problem
of
proper
disposal
of
brake fluid
as
well
as
the
special
tools
re-
quired
and
the
necessary
expertise,
we rec-
ommend
that
you have

Battery
General
information
The
battery
in your Audi
does
not
need
any
main
-
tenance
under
normal
operating
conditions. Audi
recommends
having
the
electrolyte
level check
by an
authorized
Audi
dealer
or
authorized Audi
Service Facility
when
there
are
high
outs
ide
tem-
peratures
or
when
dr
iv
in
g all day. The
electrolyte
level
should
also be checked each
time
the
bat-
tery
is
charged
~
page
247.
Have
the
battery
checked when you bring
your
ve-
hicle
in
for
an
inspection.
It
is
a
good
idea
to
re-
place
the
battery
if
it
is
more
than
S years old.
Sometimes
when
the
airbags
deploy,
the
battery
will
be
disconnected
from
the
vehicle electrical
system
for
safety
reasons
~

in
Repair, care
and disposal
of
the airbags on page

.
Disconnecting
the
battery
The
battery
should
not
be
disconnected. Several
vehicle functions (power windows, for
example)
will
be
lost
when
the
battery
is
disconnected.
The
functions
must
be
reprogrammed
after
connect-
ing
the
battery.
To avoid this,
the
battery
shou
ld
only be disco
nnected
from
the
vehicle el
ectr
ical
system
when
it
is
absolutely necessary.
Not
running
the
vehicle
for
long periods
of
time
If
you
do
not
drive your vehicle for several days
or
weeks, electrical
consumers
are
gradually scaled
back
or
switched
off. This
reduces
energy
use
and
ensures
the
vehicle will be
able
to
start
after
l
ong
periods
of
time~
page 92.
Some
convenience
functions, such
as
inter
i
or
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.

Winter
operation
A
lot
of
stress
is placed
on
the
battery
during
cold
weather,
which
results
in
reduced
starting
ability. Have
the
battery
checked
and
recharged if
necessary
before
the
cold
weather
begins.
A
WARNING
- Work on
the
battery
requires
expert
knowl-
edge.
Contact an
authorized
Audi
dealer
or
authorized
Audi
Service Facility for informa-
tion
regarding
the
vehicle
battery.
There is a
risk for chemical
burns
or
explosions.
- Never
open
the
vehicle
battery.
Do
not
try
to
change
the
battery
electrolyte
level. Other-
wise explosive
gas
will
escape
from
the
bat-
tery
and increase
the
risk
of
an explosion.
