Before you check anything in the engine com­
partment,
a lwa ys read and heed a ll W ARN­
ING S c:> .&.. in Working in the engine compart­
ment on page 212 .
~ Read the brake fluid level from the brake
fluid reservoir
c:> fig. 186, <=> page 214,
fig . 182.
The brake flu id 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 214 .
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:~, Canadian
models: .) will come on
r:> page 15. Do not
continue to operate the vehicle. The complete b rake system shou ld be thoroughly checked
by an authorized A udi dealer or qualified
workshop and the cause co rrected . If the
b rake fluid level is too low, the brake warn ing/
indicator light w ill illuminate. Contact an au­
thorized Audi dealer
immediately .
@ Tips
The brake f luid reservoir is located under­
neath the cover .
Checking and fillin g 221
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 dec rease considerably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "F MVSS 116 DOT 4".
The brake fluid reservo ir can be d iff icult to
reach, the refore, we recommend that you
have the brake fluid changed by your author­
i zed
Audi d ealer. Your dealer has t he correct
tools, the right brake fl uid and t he 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 f luid. Observe these pre­
cautions:
- Use only brake fluid that meets SAE
spe cificat ion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 116.
Always check with yo ur authorized Audi
dealer to make sure yo u are using the
correct bra ke fluid. The correct type of
brake f luid is also indicated on the
brake f luid 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. Th is cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

This might happen, for example, when
heavy components such as the engine
b lock or transmiss io n are removed.
- When removing heavy components like
these, anchor vehicle to ho ist or add cor­
responding weig hts to mai nta in the cen ­
ter of g ravity. Otherwise, the veh icle
m ight tilt o r slip off t he hois t, causi ng
serious p ersona l injury.
(I) Note
- Be awa re of th e fo llowing points befo re
li fting the vehicle:
- The vehicle should never be lifted or
jacked up from underneath the engine oil pan , the transmission housing , the
front or rear axle or the body s ide
members. This could lead to ser ious
damage.
- To avoid damage to the underbody or
chassis frame , a rubber pad must be
inserted between the floor jack and
the lift points .
-Before driv ing over a workshop hoist,
check that the vehicle weight does not
exceed the permi ssible lifting capacity
of the hoi st.
- Before driv ing over a workshop hoist,
ensure that there i s sufficient clear­
ance between the hoist and low parts
of the vehicle.
