(!) Tips
The needles in the instrument cluster illu­
minate when the ignition is switched on.
The dials also illuminate when the lights
are switched on . The instrument illumina­
tion dims automatically as the amount of light outside decreases . This funct ion re- minds
the driver to turn the headlights on
at the appropriate time.
Setting the time/date

Fuel level
The display@ Q 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
Q page 24 . 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
Q page 2 8, On-board
computer display.
F or the tank capac ity in yo ur vehicle , refer to
the Tec hnical Data
Q page 288.
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
In vehicles without a coolant temperature in­
d icator , an indicator l ight . will turn on
when the coolant temperature is too h igh
Q page 20. Refer to Q Q) .
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 tern- perature is h
igh. This is not a cause for con­
cern as long as th e . indicator light in the
display does not turn on.
Hot range
If the L EDs in the upper area of the disp lay
and the. indicator light in the instrument
cluster disp lay t urn on , the coo lant tempera ­
ture is too high
c::> page 20.
A WARNING
I-
- Always observe the warn ing in
c::> page 217, 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 yourse lf . Let the engine
coo l off f irst unti l yo u can no longe r see
or hea r steam or coolan t escap ing.
Q) Note
- In vehicles w ith a boost pressure indica­
to r*, this indicator replaces the tempe ra­
t ur e display. To promote a long engine
service life, avoiding h igh engine speeds,
full acceleration and he avy eng ine lo ads
during approximately the first 15 m i­
nutes when the engine is co ld is recom ­
mended. The amount of time until the
eng ine is warm depends on the outside
temperat ure. Check the engine oil tem­
perature* if necessary.
c::> page 32
- Add itiona l head lights and other compo­
nents in front of the air intake impairs
the cooling effect of t he coolant. This in­
creases the risk of the engine overheat­
ing during high outs ide temperatures
and heavy eng ine load.
- T he front spoiler also he lps to d istr ibute
cooling ai r correctly wh ile driving. If the
spoiler is damaged, the coo ling effect
w ill be imp aired and the risk of the en­
gine overhea ting will increase . See an au­
thorized Audi dealer or autho rized Audi

226 Checking and Fill in g
- Do not add any type of radiator leak sea l­
ant to your ve hicle's engine coolant.
Adding rad iator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in damage not covered by your New Vehicle
Limited Warranty.
Adding coolant
Fig . 164 Engine co mpa rtment: mark in gs on the coo l­
ant expans ion tank
R ea d a nd f ollow ing th e W ARNING S before
checking anything in the eng ine compartment
¢ page 217.
Ch eck ing t he e ngi ne coolant level
"Park your vehicle on a level surface .
.. Switch the ign ition off .
" Read the coo lant level on the coolant expan­
s ion tank ¢
fig. 164. The coo lant level must
be between the markings when the eng ine
in cold. When the engine is warm it can be
sl ightly above the upper marking .
Adding coolan t
Requirement : There must be a residual
amount of coolant in the expansion tank ¢(D .
.. Let the engine cool down.
" Place a cloth over the coolant expansion
tank cap and unscrew the cap counterclock­
wise ¢&_ .
.. Add coolant mixed in the correct ratio
¢ page 225 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
c ility and have the cooling system inspected.
If the cooling system is not leaking, a loss can
come from the coolant boiling through over­
heating and being pushed out of the cooling
system.
A WARNING
The cooling system is press urized and can
become very hot. To reduce the r isk of
b urns from hot coolant:
- Do not open the coolant expansion tank
cap with the engine ho t. T here is a risk of
burns.
- Stop the eng ine and a llow it to cool.
- Protect your face, hands and arms from
escaping coolant and steam by covering
the coolant tan k cap with a large, th ick
cloth.
- Turn the coolan t tank cap counterclock­
wise slowly and keep light pressure on
the cap .
- To reduce the risk of burns, do not allow
any antifreeze or coolant to drip onto the
exhaust system or hot engine compo ­
nents. The ethy lene g lycol in engine
coo lant can catch fire under certain cir­
cumstances.
- The coolant additive 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 rad iator fan
can switch on even if the ignition is
sw itched off, which increases the risk of
pe rsonal injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the eng ine .
If this is the case,
do no t continue dr iving. See a n author ized
A udi dealer or authori zed Aud i Service Fa­
cility for assist ance.

Radiator fan
The radiator fan switches on automatically by
itself
An auxiliary electric radiator fan switches on
and off depending on coolan t temperature
and other vehicle operating conditions .
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<=>.& , 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 because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
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.
Brake fluid

Fig. 165 Engine compa rtment: cove r on the brake fluid
rese rvoir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS r::;, page 217 .
Checking and Filling 22 7
.. Read the brake fluid level from the brake
fluid reservoir <=>
fig. 165, <=> page 220,
fig. 159.
T he brake fluid 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
<=>page 220.
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)
I. (Canadian
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 light will illuminate. Contact an au­
thorized Audi dealer
immediately.
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 fluid will also decrease considerably and
decrease braking performance.
Therefore, the brake fluid must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to
reach, therefore, we recommend that you
have the brake 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.
