Battery
General information
Unde r 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 an authorized
Aud i dea ler o r qualified workshop . The elec­
trolyte leve l sho uld a lso be checked each t ime
the battery is charged ¢
page 224.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a bat tery that is older tha n 5 yea rs .
W ith certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec­
tr ica l system fo r safety reasons ¢
& in Re­
pair, core and disposal of the airbags on
page 157.
Disconnecting the battery terminals
Some veh icle functions (power w indow regu­
lato rs, for example) are lost if the battery ter­
m inals a re discon nected. These functions have
to be re lea rned after the batte ry terminals a re
connec ted agai n. T o prevent this, the battery
should o nly be d isconnec ted from the vehicle
e lec trica l syste m when absolu tely necess ary
for repairs.

I f yo u do not drive you r vehicle over a pe riod
of severa l days or weeks, elec trical co m po­
nen ts are gr adually cu t back o r swi tched off .
T his reduces energy consumption and main­
tains sta rting capab ility over a lon ger period

Some o f the conven ien ce f unct ions m ay no t
ope rate, su ch as the in ter ior lights o r the power seat adjus
tment. The convenience
funct ions wi ll be available again when yo u
tu rn on the ignition and sta rt t he engine.
Winter operation
Du ring the w inte r mon ths , b att ery capac ity
tends to dec rease as temperatures drop . This
is beca use more power is a lso consumed w hile
starting, and the headlights, rear win dow de­
f ogger, etc., are used more often.
Avoid unnecessa ry powe r consumpt ion, pa r­
ticu lar ly in ci ty traffic o r when traveling only
sho rt distances . Let yo ur autho rized A udi
dealer check the capacity of the vehicle bat ­
tery before w inter sets in ¢
page 224. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer .
