Fuel level
The display @
c;, page 10, fig. 3 only works
when the ignition is sw itched on . When the
d isplay has reached the reserve mark, the bot­
tom LED wi ll turn red and the
tD indicator
light turns on¢
page 23 . The bottom LED
blinks red when the fue l level is very low .
The on -board computer shows the range
based on the fuel leve l
c;, page 2 7, On-board
computer display.
F or the tank capac ity in yo ur vehicle , refer to
the Tec hnical Data ¢
page 280.
CJ) Note
Never d rive until the tank is completely
empty. The irregular supp ly of fuel that re­
sults from that can cause the engine to
misfire. Uncombusted f uel will then enter
the exha ust system. This can cause over­
heating and damage to the catalytic con­
verter .
Coolant temperature indicator
The coolant temperature ind icator @
c::> page 10, fig . 3 only works when the ignition
is switched on . T o prevent engine damage, ob­
serve the fo llow ing notes about the tempe ra­
ture ranges.
Cold range
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high engine speeds,
fu ll acce le rat ing and heavy engine loads.
Norm al range
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving condi­
tions. The L EDs higher up may turn on if the
engine is under heavy load or the o uts ide tem­
perat ure is h igh. This is not a cause for con­
cern as long as the. indicator light in the
display does not t urn on. Hot range
If the L
EDs in the upper area of the d isp lay
and the. indicator light in the instrumen t
cluster disp lay t urn on, the coo lant tempe ra­
ture is too high
c::> poge 19.
A WARNING
-Always observe the warning in
c;, page 214 before opening the hood
and checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coo lant
dripping from the engine compartment .
You could burn yourself. Let the engi ne
coo l off first until you can no longe r see
or hea r steam or coolant escaping.
([) Note
- Add itiona l headlights and other compo ­
ne nts in front of the a ir intake impairs
the cooling eff ect of the coolant. This in­
creases the risk of the engine over heat ­
ing dur ing high outs ide temper atures
and heavy eng ine load .
- The front spoiler also he lps to distr ibute
cooling air correct ly wh ile driving.
If the
spoiler is damaged, the coo ling effect
wi ll be impai red and the risk of the en­
gine overheating will increase. See an au­
thorized Audi dealer o r authorized Aud i
Service Facility for ass istance.

Checking th e engine coolant leve l
"'Park your vehicle on a level surface .
"' Switch the ign ition off.
"' Read the coo lant level on the coolant expan­
s ion tank
c::> fig. 168. The coolant level must
be between the markings whe n the eng ine
in cold. When the eng ine is warm it can be
slight ly above the upper marking .
Adding coolant
Requirement: There must be a residua l
amo unt of coolant in the expansion tank
c::> (D .
"'Let the engine coo l down .
"' Place a cloth over the coolant expa nsion
tank cap and unscrew the cap counter clock­
wise <=:>
A.
"'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.
Che cking and Fillin g 221
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.

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
