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
quires little attention.
T he 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 condit ioned water and the manufactur ­
er's glycol-basedcoolant add itive G 13 antifreeze
with anticorrosion additives (SO% for USA mod­
e ls; 60% for Canadian mode ls). This m ixture
both ass ures the necessa ry frost protection and
protects metal components in the engine's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ration of the coolant in
the summer by adding p lain water.
The propor­
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
_& WARNING
Before you check anythi ng i n t he engine com­
partment, always read and heed all WARN ­
INGS
¢ .&. in Working in the engine compart­
ment on page 193 .
(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in your
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
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 additive to 60%.
- When adding coolant additive to your cool­
ing system, remember :
- We recommend us ing only coolant add i­
tive G12+ + or G13 for yo ur vehicle. This
coolant addit ive is avai lab le at aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

Check ing and F illing
The location of the coolant expansion tank can be
seen in the engine compartment illustration
¢ page 195.
To obtain an accura te reading, the eng ine must
be switched off .
The expans io n tank in your vehicle is equipped
with a n elec tric coolant level sensor.
When the coolant level is too low, the war ning
lig ht in the Auto-Check System¢
page 15 will
blin k until you add coo la nt and the level has bee n
restored to normal. Even t hou gh the re is an e lec­
tr ic coolant level sensor, we still re commend you
check the coo lant level from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling
system. I n the event of coolant loss, the cooling
system should be inspected immediately by your
author ized Audi dealer. It is not enough me rely
to add coolant.
I n a
se aled system, losses can occur only if the
boi ling point of the coo lant is ex ceeded as a re ­
sul t of over heat ing.
A WARNING
T he cooling system is unde r pressure and can
get very hot . Red uce the risk of scalding from
hot coolant by following these steps.
- Turn off the eng ine and a llow it to cool
down .
- Protect your face, hands and arms from es ­
caping fluid and steam by cove ring the ca p
with a la rge, thick rag.
- Turn the cap s lowly and very ca refu lly in a
counter-clockwise direction w hile ap ply ing
light, downwa rd pressure o n the top of the
cap.
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exha ust system or
hot eng ine parts. Under certain conditions,
the ethy lene g lycol in e ngine coolant can
catch fire.
(D Note
Do not add any type of radiato r leak sealant
to your veh icle's engine coolant. Adding radia-

tor repair fluid may a dverse ly affect the func ­
tion and performance of your coo ling system
and could result in damage not covered by
your New Vehicle Limited Warranty.

A WARNING ,~
- The cooling system is under pressure and
can get very hot. Reduce the risk of scald ing
from hot coolant by following these steps.
- Turn
off the engine and allow it to coo l
down.
- Protect you r face, hands and arms from
escaping fluid and steam by cover ing the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise d irection while applying
light, downward p ressure on the top of
the cap.
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in cond i­
tions, the ethylene glycol in eng ine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its orig inal container and well out
of the reach of children.
- If you dra in the coolant, it must be caught
and safely stored in a proper conta iner
clearly marked "poison".
- 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 driving . Seek professional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire. Excess coolant will be
fo rced o ut through the pressure relief valve
i n the cap when the e ng ine be comes hot.
- If, in an emergency, only wate r can be add­
ed, the co rrect r atio betwee n wate r and an­
tifree ze

Rad iator fan
The radiator fan switches on automatically by it­
self .
The radiator fan is driven by the engine via the V­
belt. The viscous clutch regulates th e speed of
the fan accord ing to the temperature of the cool­
ant .
An auxiliary e lectr ic radiator fan* switches on and
off depending on coo lant temperature and other
vehicle operating conditions.
After you switch the engine
off, the auxiliary fan
can continue running for up to 10 m inutes -even
with the ignition
off. It can even switch on aga in
later by itself
Q .& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up beca use the
veh icle is parked in intense sunlight.
A WARNING
- To reduce the r isk of persona l injury neve r
touch the radia to r fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not ru nning .
- The a uxiliary radiator fan sw itches on auto­
mat ically when the eng ine coolant reaches a
certa in temperature a nd will continue to run
until the coolant temperature d rops.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
gi vehicle and can lead to sudden ...... N

and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of..,.

today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by veh icle owners.
Also , sa fet y a nd
en vironmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
g ine and transm ission parts wh ich an owner can
pe rform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, test ing devices and other
equ ipment available to specially trained work ­
shop perso nnel i n order to assure proper per­
formance, re liability a nd safety of the ve hicle and
its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and re liab il ity of you r
vehi cle and eve n void your vehicle warra nty .
Therefo re, proof of se rvicing in accordance with
the m aintenance schedule may be a condition fo r
upho ld ing a possib le warranty claim made wi thin
the warranty period.
Above all , ope rational safety can be adversely af­
fected, cre ati ng u nnecessa ry risks fo r yo u and
your passengers.
I f in doubt about any se rvicing, have it done by
your author ized Audi dealer or any properly
eq uipped and qua lified workshop. We strongly
