178 Checking and filling
Brake fluid
Hove the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
brake fluid w ill also decrease considerably and
decrease b rak ing performance .
Therefore, the brake f lu id must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 1 16 DOT 4".
Brake fl uid is rep laced according to the Audi
maintenance service schedule. Your author­
ized Audi dealer is equipped with the necessa­
ry special tools and replacement parts, has
the necessary expe rtise, and can d ispose of
the used fluid .

dealer to m ake sur e you are u sing the
correct br ake f luid. The co rrec t type of
b rake fluid is a lso indica ted on the
b rake fluid reservoir .
- The brake flui d must be new. Heavy use
of the brakes can ca use a vapor loc k if
the brake fl uid is left in t he system too
l o ng. This can ser io usly affect the effi­
ciency of the brakes as well as yo ur

Battery
General information
All work on the ba ttery requires technical
knowledge.
The battery is located be hind the cov er in the
l u ggage compa rtment. Remove the cover by
pu shing i t to the left an d lift ing it o ut.
The battery is practically maintenance-free
and is checked as pa rt of your ve hicle's main­
tenance se rv ices .
You are we ll advised to replace a battery that
i s older tha n 5 yea rs .
Disconnecting the battery terminals
Some vehicle f unctions (power window reg u­
l ators, for example) are lost if the battery te r­
mina ls are disconnected. T hese functions have
to be relearned after the battery termina ls are
co nn ected aga in . T o p revent th is, t he battery
shou ld only be disconnected from the ve hicle
elect ric al sy stem w hen abso lutely ne cessary
f or rep airs.
Vehicles not driven for long periods
The battery becomes d ischarged due to quies­
cent current consume rs even when the vehicle
is not used. With extended pe riods of non-use
in t he
cold season, yo u should have t he ve hi­
cle b attery removed by an autho riz ed Aud i
dealer or qualif ied workshop and stored in an
frost-free place. T his prevents the battery
from "freezing" and thereby being destroyed.
D uring the
warme r seasons it is enough to
