compartment. Wait until no steam or cool­
ant can be seen or heard before carefully
opening the hood.
- Keep children away from the engine com­
partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxiliary
electric fan is temperature controlled and
can switch on suddenly.
- Never open the coolant reservoir cap when
the engine is still warm . The coolant system
is pressurized and hot coolant could spray
out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary:
= Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment
could start a fire.
- Keep an approved fire extinguisher imme­
diately available.
- To avoid electrical shock and personal injury
while the engine is running or being started,
never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake, move
selector lever of automatic transmission
to "P" (Park).
- Always use extreme caution to prevent
clothing , jewelry, or long hair from get-
194
ting caught in the radiator fan, V-belts or
other moving parts, or from contacting
hot parts. Tie back hair before starting,
and do not wear clothing that will hang or
droop into the engine.
- Minimize exposure to emission and chemi­
cal hazards

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-
200
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
urge you to g ive your author ized Audi dealer the
opportunity to perform a ll scheduled mainte ­
nance and necessary repairs. Your dealer has the
fac ilities, original parts and tra ined specialists to
keep your veh icle running properly .
Performing limited ma intenance yourself
The fo llow ing pages describe a limited number of
procedures which can be performed on your vehi­
cle with o rdinary tools, should the need arise and
tra ined personnel be unavailable. Before per­
forming any of these procedures, always thor­
ough ly read a ll of the app licab le text and careful­
l y follow the instructions g iven . Always rigorously
observe the
WARNINGS prov ided .
Before you check an ything in the eng ine com ­
partment, alw ays read and heed all WARNINGS

ment on page 193 . Con
sumer inf ormation
A WARNING
- Ser ious personal in jury may occur as a result
of improperly performed maintenance, ad ­
justments or repairs .
- Always be extremely careful when work ing
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­ mon sense. Never risk pe rsonal in jury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fu lly familiar wi th these
or other proce dures with respect to t he ve­
h icle, o r are uncerta in how to pro ceed.
- Do not do a ny work withou t the proper tools
a nd equ ipment. Have the nece ssary wo rk
done by your authorized Audi dealer or any
p roper ly equipped and qualifie d wo rkshop.
- T he engine compa rtment of any motor veh i­
cle is a potent ially hazardous area . Never
reach into the area around or touc h the radi­
ator fan. It is temperature controlled and
can switch on suddenly - even when the en­
g ine is off and the ignition key has been re­
moved . The rad iator fan switches on auto ­
mat ically when the coo lant reaches a certain
temperature and will con tinue to ru n until
the coolant temperat ure drops.
- Always remove the igni tion key befo re any­
one gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work underneat h
the vehicle . The jack supplied with the veh i­
cle is no t adequ ate for t his pu rpose and
could collapse c ausing se riou s personal in­
jury .
- If you mu st wor k unde rne ath t he vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels a re always sec urely blocked and that
the engine cannot be started.
- Always make sure the transmission se lector
lever (a utomatic t ransmiss ion) is in "P"
(Park position) and the park brake is firmly
applied.
