Fig. 179 Engine compartme nt: Cover on the brake flu ·
id reservo ir
Before you check anything in the engine com
partment,
a lwa ys re ad and heed all WARN·
ING S ¢.&._ in Working in the engine compart
ment on page 195 .
.. Read the brake fluid level from the brake
fluid reservoir
¢ fig . 179 , ¢page 197,
fig . 174.
The brake fluid level must be be
tween the "MIN" and
"MAX" markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the
left side
¢ page 197.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably be
low the "MIN" mark, the brake warning/indi
cator light (U.S. models:
11111 , Canadian
models :. ) will come on
¢page 15. Do not
continue to operate the vehicle. The complete brake system should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause corrected .
If the
brake fluid level is too low, the brake warn ing/
indicator light w ill illuminate. Contact an au
thorized Audi dealer
immedi atel y.
@ Tips
The brake fluid reservoir is located under
neath the cover.
Changing brake fluid
Have 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
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
every two year s. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "F MVSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the brake fluid changed by your author
ized
Audi d ealer . Your dealer has the correct
tools, the right brake fl uid and the know -how
to do this for you .
A WARNING
- Brake fluid is poisonous . It must be stor
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap
propriate brake flu id. Observe these pre
cautions:
- Use only brake f luid that meets SA E
specifica tion
J 1 7 03 and conforms to
Federa l Moto r Ve hicle Standard 1 16.
Always check with yo ur authorized Aud i
dealer to make sure yo u are using the
correct brake fluid. The correct type of brake f lu id is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong. This can seriously affect the effi
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
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 an authorized
Aud i dealer or qualified workshop . The elec
trolyte leve l should also be checked each time
the battery is charged c>
page 207.
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 .
W ith certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec
tr ica l system for safety reasons c>
.&. in Re
pair, care and disposal of the airbags on
page 144.
Disconnecting the battery terminals
Some vehicle functions (power w indow regu
lators, for example) are lost if the battery ter
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this, the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, elec trical compo

Winter operation
D ur ing the w inte r mon ths, bat tery capa city
tends to dec rease as tempera tures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de
fogger, etc., are used more often.
Avoid unnecessary powe r consumpt ion, pa r
ticular ly in city traffic or when traveling only
sho rt distances. Let yo ur authorized A udi
dealer check the capacity of the vehicle bat
tery before w inter sets inc>
page 207. A well
charged battery will not on ly prevent starti ng
problems w hen the weather is cold, but w ill
also last longer.
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freeze . This will
p revent it from be ing damaged and having
to be repla ced.
