- When switching the ignition on, the nee­
dles in the instrument cluster swing up­
ward briefly.
- The illumination for the instrument clus­
ter lights up whenever you switch on the
i gnition with the
vehicle headlights off .
As the daylight fades, the instrument
cluster illumination likewise dims auto­
matically a nd will go out completely
when the outside light is
very low. This
feature is meant to remind you to switch
on the headlights when outside light
conditions become poor.
Engine coolant temperature gauge
The engine coolant gauge c> fig. 3 CD only
works when the ignition is on. To prevent
damage to your engine, please note the fol­
lowing important points:
Engine cold
If the needle is at or close to the bottom of
the gauge, the engine has not yet reached its
operating temperature. Avoid high engine
speeds, heavy engine loads, and heavy throt ­
tle app lications.
Normal temperature
When the engine has reached its operating
temperature, the needle will
move to the mid­
dle of the gauge and remain there . If the en­
gine is working hard at high outs ide tempera­
tures, the needle may
move higher on the
gauge. This is not a cause for concern as long
as the . warning light in the instrument
cluster display does not illuminate. If the.
warning light in the instrument cluster dis­
play flashes, this can mean one of two things:
either the coolant
temperature is too high, or
the coolant
level is too low c> page 18 Ill-

/! WARNING
- Always observe the warning in
¢ page 205, Engine compartment, be­
fore opening the hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
i ng effect of the radiator . At h igh outside
temperatures or high engine load, the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this could reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Audi dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engin e RPM
(revolutions per minutes).
If engine RPM d rops be low 1,500 , you should
downshift to the next lower gear. The red area
at the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod . Before reaching this area, move these­
lector lever to position D/S or ease your foot
off the accelerator pedal.
(D Note
The tachometer needle@¢ fig. 3 should
only briefly be in the red zone: you cou ld
damage your engine! The beginning of the
red zone varies depending on the engine.
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.
~ button
You can perform different functions with this
button .
Fig. 4 SET but ton in th e in str ume nt cluster
The !SE T! button performs the following func­
tions:
Switching on time, date , temperature
display, and odometer
The display appears for approximately 30 sec­
onds when you press the

with the ignition off.
Starting the Auto -Check sequence
The Auto-Check system constantly monitors
certain ind iv idual functions and components
of the vehicle when the ign ition is turned on
and when the vehicle is moving .
With the ignition turned on, you can start the " Auto-Check sequence" by pressing the
!S ET i
button. You can perform an Auto-Check se­
quence when the vehicle is stationary and the
ignition is turned on or when the vehicle is
moving slower than 3 mph (5 km/h) .
In addition, the number of keys initial ised fo r
your vehicle is displayed.
L2 3/3 means that
three keys have been initialised. This feature
enables used car buyers to make sure they
have received all of the keys.
If you are given only two keys, for instance,
you should take the vehicle and the existing keys to an Audi dealer to have the missing key
disabled.
It is also important to notify your in -
surance company about the loss .

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
te cts the engine from freezing in the winter .
The cooling system is sealed and generally re­
qu ires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-based coolant additive G 13 antifreeze with
anticor ros ion add itives (50% for USA mode ls;
60% for Canadian mode ls). This mixtu re both
assures the ne cessa ry frost prote cti on and
p rotec ts metal components in the engine's
coo ling system from cor ros io n an d scaling. It
a lso raises the boiling point of the coolant.
D o not red uce the con cent ration o f th e coo l­
ant in the summe r by adding plain water .
The
proportion of coolant additive must be at least 50% but not more than 60%
to ma in­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant cou ld freeze and damage the veh i­
cle heating and eng ine cooling system .
For yea r-round driving, antifreeze is added at
the factory for temperatures down to:
- -3 1 °F (-35°C)USA
- -4 0 ° F ( - 40 °C) Canada.
A WARNING
Before yo u check any thing in the engine
compartment, always read and hee d all
W AR NIN GS
¢ .&. in Working in the engine
compartment on page 212.
(D Note
- Before win ter se ts in, have the coolan t
checked to see if t he coolant ad dit ive i n
your vehicle is suffic ient to meet the cli­
mate cond itions . T hi s is especially imp or­
tant if you live in a regi on whe re the w in­
te r is e xtremely cold. If necessary, in -
Checking and fillin g 219
crease the propo rtion of coo lant add itive
to 60%.
- When adding coolant additive to yo ur
coolin g system , remembe r:
- We reco mmend us ing o nly coola nt ad­
d itive G12++ or G13 for your vehicle .
This coolan t ad ditive is availab le at a u­
thor ized Audi dealers. O ther types of
ant ifree ze can s ignific antly red uce cor­
rosion pro tec tion . The result ing corro­
sion can ca use a loss o f coolan t and se ­
rio us en gine damage.
- D o not add any ty pe of rad iator leak seal­
ant to yo ur vehicle 's engine coolan t.

220 Check ing and filling
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢
page 214 .
To obtain an accurate read ing, the eng ine
must be switched off .
The expans io n tank in you r vehicle is equipped
with an e lectr ic cool ant level sensor.
When the coolant level is too low, the warning light in the A uto-Check System ¢
page 18 will
b link until you add coo lant and the level has
been restored to no rm al. Even though the re is
an e lec tric coolant level sensor, we s till rec ­
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolan t loss, the cool ­
i ng system should be inspected immedia tely
by your authorized A udi dealer. It is not
enough merely to add coolant.
I n a
s e aled system, losses can occur only if
the boiling poin t of the coolant is excee ded as
a result of overheating.
A WARNING
The cooling system is unde r pressure and
can get ve ry hot. Reduce the risk of sca ld­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to cool
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and ve ry carefu lly in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap .
- To avoid being b urned, do not spill ant i­
freeze or coolant on t he exhaust system
or hot eng ine parts. Unde r certain condi­
tions, t he ethy lene g lycol in engine cool­
an t can ca tch fire.
(D Note
Do not ad d any type of radiator leak sea l­
ant to your veh icle's engine coo lant. Add­
i ng radiator repa ir fluid may adverse ly af­
fect the funct ion and performance of your
cooling system and could result in damage not cove red by your New Veh icle L imited
War ran ty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine com­
partment,
always read and heed all WARN­
INGS c> &. in Working in the engine compart ­
ment on page 212.
.. Turn off the engine.
.. Let the engine cool down.
.. Place a thick rag over the coolant expansion
tank ¢
fig. 178 and carefully turn the cap
co unter-clo ckwise ¢,&. .
.,. Add coo lant.
.. Twis t the cap on aga in
t ightly.
Replacement engine coo lant must confo rm to
exact spec ificat ions
¢ page 219, Coolant. We
re commend using on ly coo la nt additive G 12+
+ , G 13 or in an eme rgen cy G12+. Do
not use a
different additive. In an emergency use plain
water until yo u can get the correct additive
and can restore the correct ratio . This shou ld
be done as soon as possible .
If you have los t a cons iderab le amount o f
coolant , then you sho uld ad d cold antifreeze
and cold wate r on ly w hen the engine is cold.
Always use
new engine coo lant when refilling.
Do not f ill coo lant abov e the "MAX" mark . Ex­
cess coo la nt w ill be fo rced o ut thro ugh the

gine becomes hot.
A WARNING
-= -
-The cooling system is under pressure and
can get very hot. Reduce the risk of ..,.

scalding from hot coo lant by following
these steps.
- Turn
off the engi ne and a llow it to cool
down.
- Protect your face, hands and arms from
escapi ng fl uid and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very ca refully

the top of the cap.
- T o avo id being burned, do no t sp ill an­
tifree ze o r coolan t on t he exh aust sys­
tem or ho t engine parts . Un der certain
conditions, the ethylene glyco l in en­
gine coolant can catch fire .
- Antifree ze is poisono us. Always store an­
tifreeze in its or iginal co ntainer and we ll
o ut o f the reac h of children.
- If you drain the coolant , it must be
caught and safely stored in a p roper con ­
tainer clear ly marked "poison".
(D Note
- Coolant po llutes the env ironment and
could ca use a n engine fire . Excess coo l­
ant wi ll be forced out through the pres ­
sure re lief va lve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze¢
page 219 must be re­
stored as soon as possib le .
@ For the sake of the environment
Drained coolant should not be re used . Al­
ways dispose of used c oolant while observ­
ing all envir onmental regulations .
Radiator fan
The radiator fan switches on automa tically by
itself
T he radiator fan is driven by the engine via the
V-be lt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
Checkin g and fillin g 221
An auxiliary electric radiato r fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing con ditions.
After yo u switc h the engi ne off, the aux iliary
f an can con tinue r unning for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢ & , if
- t he temperatu re of the engine coo lant rises
due to the heat b uild -up from the en gine in
the engi ne compartment, or
- the engine compartment heats up be cause
the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal in jury nev­
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
contro lled and can switch on sud denly
even when the engine is not running.
- The a uxiliary radiator fa n switches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops .
