s ion tank
c::> fig. 168. The coolant level must
be between the markings whe n the eng ine

slight ly above the upper marking .
Adding coolant
Requirement: There must be a residua l
amo unt of coolant in the expansion tank

"'Add coolant mixed in the correct ratio
c::>page 220 up to the upper marking.
"' Make sure that the fluid level remains sta-
ble. Add more coolant if necessary.
"' Clove the cap securely.
A coolant loss suggests a leak. Immediately drive your vehicle to an authorized repair fa­
cility and have the cooling system inspected.
If the cooling system is not leaking, a loss can
come from the coolant boiling through over ­
heat ing and being pushed out of the cooling
system.

A WARNING
The cooling system is pressurized and can
become very hot. To reduce the r isk of
burns from hot coolant:
- Do not open the coolant expansion tank
cap with the engine hot . The re is a risk of
burns .
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from
escaping coolant and steam by covering
the coolant tank cap with a large, th ick
cloth .
- Tu rn the coolant tank cap counterclock­
wise slowly and keep light pressure on
the cap.
- To reduce the risk of burns, do not allow
any antifreeze o r coolant to drip onto the
exhaust system or hot engin e compo­
nents . The ethy lene g lycol in eng ine
coo lant can catch fire under certai n cir­
cumstances.
- The coolan t addi tive and the coolant can
be dangerous to your health. For this
reason, keep the coo lant in the origina l
container away from ch ildren. There is a
risk of poisoning.
- When working in the engine compart­
ment, remember that the radiator fan
can switch on even if the ignition is
sw itched off, which increases the risk of
personal injury.
(D Note
Do not add coolant if the expans ion tank is
empty. Air could enter the cooling system
and damage the eng ine. If this is the case,
do not continue dr iving. See an author ized
Audi dealer or authorized Audi Service Fa ­
c ility for ass istance.
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions .
IJJ,

222 Checking and Filling
After you switch the engine off, the auxiliary
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
even when the engine is not running.
- The auxiliary radiator fan switches on au­ tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

Before you check anything in the engine com­
partment,
always read and heed all WARN ·
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.
