Battery
General information
Under
normal
operating conditions, the battery
in your Audi does not need any ma intenance.
With high outside temperatu res or long daily
d rives we recommend that you have the electro-
lyte level checked by a service facility . The elec-
trolyte level should a lso be checked each time
the battery is charged ¢ page 230 .
Have the bat t ery checked when you take your ve-
hicle in for service . You are we ll advised to re-
place a battery that is older than 5 years .
With certa in types of airbag deploymen t , the bat-
tery is disconnected from the vehicle electrica l
system for safety reasons ¢
.&.
in Repair, core
and disposal of the airbags on page 158.
Disconn ecting the battery t erminal s
Some veh icle funct ions (power window regula-
tors, for examp le) are lost if the battery termi -
na ls are disconnected. These functions have to be
relearned after the battery terminals are con-
nected aga in. To prevent this, the battery shou ld
only be disconnected from the vehicle electrical
system when absolutely necessary for repairs.
Ve hicles not driven fo r long period s
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca-
pability over a longer period ¢ page 194. Some
of the convenience funct ions may not operate,
such as the inter ior lights or power seat adjust-
ment. The convenience functions will be ava ilab le
again whe n you swit ch on the igni t ion and sta rt
the engine.
Winte r operation
During the winter months, battery capacity tends
to decrease as temperatures
drop . This is because
mo re power is also consumed w hile starting, and
the head lights, rear w indow defogger, etc ., are
used more often.
Avoid unnecessary power consumption, part icu-
larly in city traffic or when traveling only short
228
distances. Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in
¢
page 230 . A we ll charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer.

Tips
If your vehicle is left standing for several
weeks at extremely low temperatures,

where it will not freeze . This will prevent it
from being damaged and having to be re-
placed.
