Battery
General information
Under normal operating conditions, the bat-
tery in your Audi does not need any mainte -
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by a service fa-
cility. The electrolyte level shou ld also be
checked each time the battery is charged
¢ page 237.
Have the battery checked when you take your
ve hicle in for service . You are well adv ised to
replace a battery that is older than 5 yea rs.
With certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec-
tr ical system for safety reasons ¢ .&.

pair, core and disposal of the airbags on

Disconnecting the battery terminals
Some vehicle functions (power window regu-
lators , for example) are lost if the battery ter-
minals a re d isconnected. These func t ions have
to be re lea rned after the batte ry t erm inals a re
connected agai n. To prevent this , the bat t ery
should only be d isconnec t ed from t he vehicle
e lect rical system when absolu t ely necessa ry
for repairs .

Winter operation
During the winte r mon t hs, bat t ery ca pa city
tends to d ecrease as t empera t ures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de-
fogger, etc., are used mo re often.
Avoid unnecess a ry powe r consumpt ion, pa r-
ticu lar ly in city traffic or when traveling only
sho rt distances. Let your authorized Aud i
dealer check the capacity of the vehicle bat -
tery before winter sets in ¢

charged battery will not on ly prevent star t ing
problems when the weather is cold, but will
also last longer .
