Always check with your authorized Audi
deale r to make s ure you are using the
correct brake f luid. The correct type of
b rake fluid is a lso indicated on the
b rake fluid reservoir .
- The brake f luid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fl uid is left in t he system too
long. This ca n ser ious ly aff ect th e effi­
ciency of the bra kes a s well as yo ur
safety. This could resul t in an accid ent.
(D Note
Brake fl uid will damage the paint of your
ve hicle .
@ For the sake of the environment
Because of the problem of proper d isposa l
of brake flu id as we ll as the special tools
req uired and the necessa ry expert ise, we
recom mend tha t you have t he b rake fluid
changed by your aut hor ized Audi de aler.
Battery
General information
The batte ry in you r Audi does not need any
maintenance unde r
normal operating condi­
tions . Aud i recommends having the elect ro­
l y te level check by a n author ized Audi dealer
or author ized A udi Se rv ice F acili ty when there
a re
high outside tempe ra tur es or when dr iv ing
all day. The e lec trolyte level sho uld also be
checked each time the battery is charged
¢ page 225.
Have the bat tery c hecked w hen you br ing yo ur
ve hicl e in for an inspec tion. I t is a good idea
to re place the battery if it is mo re than 5 years
old .
D uring certa in types of a irbag deploymen ts,
t he bat tery is disconnected from the vehi cle
e lectrical system fo r safety reasons ~ &.

Checking and Fillin g 223
Disconnecting the battery terminals
Some vehi cle fu nctions (such as power w in ­
dows) a re not ava ilable when the batte ry is
disco nnected . These fu nctions must be p ro­
grammed afte r the battery is reconnected . To
avo id hav ing to do this, only disconnect the
battery from the vehicle electrical system
whe n that is necessary to perform repairs .
To reprogram the functions, proceed as fo l­
lows:

Remo te control key If the vehicle does no t
or r

goes out after driv ing
a few meters
Not running the vehicle for long period s
of time
If you do not drive your vehicle fo r several
days or weeks, elect rical componen ts are
gradua lly reduc ed o r switched off. This re­
duces e nergy consumption and maintai ns the
vehicle 's ability to star t ove r a long per iod of
t ime ~
page 193. Some co nvenience func­
tions, s uch as in terior lighting or power sea ts*
may not work . These convenience functions
will be ava ilab le again once you switc h the ig­
nit ion on and sta rt the engine.
Winter operation
D uring the winte r mon ths, i t is common for
the battery capacity to dec rease as the tem ­
peratures become lower . This is because more
power is needed to start the vehicle and com ­
ponents such as the head lights and the rear
window defogger are used more frequently . .,..
