Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects 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 factory
with a permanent coolant which does not need to
be changed. The coolant consists of
a mixture of
specially conditioned water and the manufactur­
er's g lycol-basedcoo lant additive G 13 antifreeze
w ith anticorrosion addi tives (50% for USA mod­
e ls· 60% for Canadian mode ls). This m ix ture
'
both ass ures the ne cess ary fros t protection and
p rotects metal com ponents in the engi ne's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ra tion of the cool ant in
the s ummer by addi ng p la in water.
The propor­
tion of coolant additive must be at lea st 50 %
but not more than 60 %
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coo lant could
freeze and damage the vehicle heat ing and en­
g ine cooling system .
For year -round driving, antifreeze is added at the
factory for temperatures down to:
- -3 1 °F
c -3s0c) usA
- -4 0° F ( -40°C) Canad a.
I f you must add coolant, use a m ixt ure of wa ter
and coolant add it ive. M ixing the coolant additive
with d istilled water is recommen ded.
_& WARNING
B efore you che ck anyt hing i n the engine com ­
partmen t, a lways read and heed all WARN -

INGS ~ & in Working in the engine compart­
ment on page 220.
(D Note
- Be fore w inter sets in, have the coolan t
checked to see if the coo lant additive in your
vehicle is suff ic ient to meet the climate con­
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant addi tive to 60% .
- Whe n adding coolant additive to your cool­
ing system, remember:
- We re commend usin g on ly coo lant addi­
tive G12++ o r G13 fo r yo ur vehicle. This
coolant ad dit ive is availab le at authorized
Audi dealers. Other types of antifreeze can
significantly reduce corrosion protection.
The resulting corrosion can cause a loss of
coolant and serio us engine damage.
- Do not add any type of radiato r leak sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and perfo rmance of yo ur cooling
system and cou ld resu lt in damage not cov­
ered by your New Ve hicle Li mited War ranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

.... .... .,. Park your vehicle on a level surface .
.,. Turn
off the ignition.
.,. Read the engine coolant level from the coolant
expansion tank
c> fig . 200, c> page 222,
fig. 197. With a cold engine, the coolant level
should be between the "MIN" and "MAX" mark­
i ngs . When the engine is warm, the level may
be s light ly above the
"MAX " marking .
T he location of the coolant expans ion tank can be
seen in the engine compartment illustrat ion
i=> page 222.
To obtain an accurate reading, the engine must
be sw itched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System
c:> page 29 wi ll
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec­
tr ic coolant level sensor, we still recommend you
check the coolant level from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
syst em. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant .
In a
sealed system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheat ing .
(D Note
Do not add any type of radiator leak sealant
to your veh icle's engine coolant. Adding radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine compart­
ment,
always read and heed all WARNINGS

Requirement: The re must be a residual amount
of coolant in the expans io n tank
c>@.
.,. Turn off the engine .
.,. Let the engine cool down.
.,. Place a thick rag over the coolant expansion
ta nk
c:> page 226 , fig. 200 and carefully turn
the cap counter-clockwise
c> _&. .
.,. Add coo lant mixed in the correct ratio
c:> page 226, Coolant up to the MAX marking .
.,. Make sure that the f luid level remains stable.
Add more coolan t if necessary .
.,. Twist the cap o n again
tightly.
Replacement engine coolant must conform to ex­
act specifications
c:> page 226, Coolan t.
We recommend using only coolant addit ive Gl2 +
+ , Gl3
or in an emergency Gl2+. Do not use a
different additive . In an emergency use plain wa­
ter until you can get the correct addit ive and can
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of coo l­
ant, then you shou ld add cold antifreeze and cold
water only whe n the engine is cold.
Always use
new e ngine coolant when refilling.
Do not fill coolant above the "MAX " mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
A WARNING
-- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps .
- Turn
off the eng ine an d allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Tu rn the cap slowly and very carefully in a
counter-clockwise direction whil e applying
light, downward pressure on the top o f
the cap .

Checking and Filling
-To avoid bein g burned, do not spill anti­
f reeze or coolant on the exhaust system or
hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­ ant can catch fire.
- Antifreeze is poisonous . Always store anti­
freeze in its original container and well out
of the reach of children .
- If you dra in the coolant, it must be ca ught
and safely stored in a proper conta iner
clearly marked "poison".
(D Note
- Do not add coolant if the expansion tank is
empty . Air cou ld enter the cooling system
and damage the eng ine .
If this is the case,
do not continue dr iving . Seek professional
ass istance.
- Coolant pollutes the e nvironment a nd could
cause an eng ine fire. Excess coolant will be
fo rced o ut through the pressu re relief valve
i n the cap when the eng ine be comes hot .
- If, in an emergency, o nly wate r can be add­
ed, the co rrect ratio between water and an­
tifree ze ~
page 226 mus t be resto red as
soon as possib le .

Drained cool ant sho uld not be reused. Always
dispose of used coo lant w hile obse rving all

Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is dr iven by the eng ine v ia the V­
be lt . The visco us cl utch regula tes the speed of
the fan acco rding to the tempera ture of t he cool­
ant.
An aux iliary ele ct ric radiator fan* swit ches on and
off depending on coolant tempera tu re and o ther
ve hicl e operat ing cond itions .
After you switch the engine off , the auxiliary fan
can cont inue runn ing fo r up to 10 minutes - even
228
with the ignition off . It can even switch o n aga in
l ater by itself~.&. , if
- the tempera ture of the engine coolant rises d ue
to the hea t build- up from the engine in the en ­
gine compartment, or
- the engine compa rtme nt heats up bec ause the
veh icle is parked in intense s unlight.
A WARNING
- To reduce the r isk of personal injury never
touch the radiator fan.
- The a uxiliary e lectric fan is temperat ure
controlled and can switch on suddenly even
when the engine is not runn ing .
-
-The a uxiliary radiator fan switches on a uto ­
mat ically when the eng ine coolant reaches a
certain temperature and will continue to r un
until the coo lant temperature drops.
