Before you c hec k anythi ng in the engine compartment,
alwa ys r ead and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 277.
- Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank==>
page 284, fig. 211. With a cold engine, the
coolant level should be between the "min" and "max"
markings . When the engine is wa rm, the level may be
sligh tly above the "max" marking .
The locat io n of the coolant expansion tank can be seen in the engine
compartment ill ustration ~
page 278.
To obta in an accurate reading, the engine must be sw itched off.
The expans ion tank in your vehicle is equ ipped with an electric coolant
level sensor .
When the coolan t level
is too low, the warn ing light in t he Au to-Che ck
System ~
page 2 7 will blink until you add coo lant and the level has
bee n restored to normal. Even though the re is an elect ric coolan t
level sensor, we still recommend you check the coolant leve l from
time to time .
Coolant loss
Coolant loss may ind icate a leak in the cooling system. I n the event of
coo lant loss, the cooling system should be inspected immed iately by
yo ur au tho rized A ud i dea le r.
It is not enough mere ly to add coolant.
In a
s e a le d system, losses can occur only if the bo iling point of the
coo lant is exceeded as a resu lt of overheating .
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coo lant. Add ing radiator repa ir fluid may adverse ly affect the func­
tion and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warra nty. •
Safety first
Adding coolant
Be very careful when adding engine coolant.
B efore you check a nything in t he engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 2 77.
- Turn off the engine.
- Let the engine cool down .
- Place a th ick rag over the coolant expansion tank
==>
page 284 , fig. 211 and carefully twist t he cap counter­
clockw ise ==>& .
- Add coolant .
- Twist the cap on again
tightly .
Replacement eng ine coolant must conform to exact spec ifications
~ page 284, "Coolant". Even in an emergency, if coolant additive
G 12++, G12+ or G12 is not available, do
not use a different addi tive .
Use plain water instead until you can get the correct additive and can
restore the correc t ratio. This should be done as soon as possible.
If you have lost a considerable amount of coolant, then you should
add co ld antifreeze and cold water only when the eng ine is co ld .
Always use
new engine coo lant w hen refilling.
Do not fill coolant above the "MAX" mark. Excess coolant will be
forced ou t th rough the p ress ure relief v alve in the cap when the
engine becomes hot .
& WARNING
• The cooling sy stem i s under pres su re a nd can get very hot.
Reduc e the ri sk of scalding from hot coolant by following the se
steps.
-Tu rn off the engine and allow it to co ol d own . _,.

& WARNING (conti nu ed )
- Prote ct your face , hand s and arms from escaping fluid and
steam by covering the cap with a larg e, thick rag .
- Turn the cap slowly and ver y carefully in a counter-clockwise
direction while applying l ight, downward pre ssure on the top
of the cap.
- To avoid being burned, do not spill ant ifreeze or coolant on
the e xhaust system or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine coolant can catch fire .
• Antifreeze is poisonous. Always store antifreeze in its original
container and well out of the reach of children .
• If you drain the coolant, it mu st be caught and safely stored in
a proper container clearly marked "poison ".
0 Note
• Coolant pollutes the environme nt and could cause an eng ine fire.
Excess coo lant w ill be forced o ut throug h the pressure re lie f va lve in
the cap when the eng ine becomes hot .
• If , in an emergency, only wate r can be ad ded, the co rrect ratio
between water and antifreeze=.-
page 284 must be restored as soon
as possib le .
~ For the sake of the environment
Dra ined coolan t should no t be reused. A lways dispose of used coolant
w hile observ ing a ll enviro nmental regula tions .•
Radiator fan
The radiat or fa n sw itches on aut oma ticall y by itself .
The radiato r fa n is d rive n by t he eng ine v ia the V-bel t. T he viscous
cl utch regu lates the speed of t he fan according to the tempe rature of
the coolant . An auxiliary e
lectric rad iator fan* sw itches on and off depend ing o n
c oo lant tempe rature and other vehicle o per at ing condi tions.
After you sw itch the eng ine off, the aux iliary fa n can con tinue running
for up to 10 m inutes -even w it h the ignition off. It ca n even switch on
agai n later by itse lf ::::.- & , if
• the tempera ture of the engine coolant rises due to the heat build­
up fro m the eng ine in the eng ine comp artme nt, or
• the engine compartment heats up because the vehicle is par ked in
in tense s unligh t.
& WARNING
• To reduce the risk of personal injury never 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 automatically when the
engine coolant reaches a certain temperature and will continue to
run until the coolant temperature drops .•

s uddenly -even when the engine is off and the ignition key has
been remo ved. The radiator fan switches on autom atically when
the coolant rea ches a certain temperature and will continue to run
until the coolant tempe rature drops.
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it i s neces sary
to work unde rne ath the vehicle. The jac k supplied with the vehicle
is not adequate for thi s purpose and could collap se cau sing
