fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself
c:> .&. , if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up beca use
the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal injury
nev­
er touch the radiator fan.
- The auxiliary electr ic fan is temperature
contro lled and can switch on sudden ly

INGS c:> page 214.
.. Read the brake fluid level from the brake
fluid reservoir
c:> fig.169, c:>poge216 ,
fig. 165.
The brake f luid level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
c:> page 216 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . This is not cause for a larm.
If the brake f luid level falls
considerably be ­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models)
I. (Canad ian
models) will come on
c:> page 18 . Do not con ­
tinue to operate the vehicle. The complete brake system should be thoroughly checked
by an authorized Audi dealer or other quali ­
fied facility and the cause corrected. If the
brake fluid level is too low, the brake warning/
indicator ligh t will illuminate. Contact an au­
thorized Audi dea ler
immediately.
Changing brake fluid
Have the broke fluid changed by an experi­
enced technician.
Brake fluid absorbs moisture from the air. If
the water content in the brake f luid is too
high, corrosion in the brake system may result
after a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance.
T he refo re, the brake fluid must be changed
every two years. Always use new brake fluid
wh ich conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
T he brake fluid reservoir can be difficult to
reach, therefore, we recommend that you
have the b rake fluid changed by your author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you .
A WARNING
---Brake flu id is poisonous. It must be stor­
ed only in the closed or iginal 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:
- Us e only brake fluid that meets SAE
specification
J 1703 and conforms to
Federa l Motor Vehicle Standard 116.
