_& 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 a llow itto cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slow ly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spi ll an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glycol in en­
g ine coolant can catch fire .
- Antifreeze is poisonous. Always store an­
tifreeze in its or iginal containe r and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the env ironment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
su re relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the cor rect ratio between water
and antifreeze ¢
page 223 must be re­
stored as soon as possib le.
@ For the sake of the environment
Drained coolant should not be reused . A l­
ways dispose of used coolant while obse rv­
ing all environmental reg ulations.
Checkin g and fillin g 225
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and
off depending on coolant temperature
and other vehicle operat ing cond it ions .
After you switch the engine
off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition
off. It can even switch
on again later by itself ¢&. , if
- the temperature of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
_& WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certa in temperature and will
continue to ru n until the coolant temper­
ature drops.

Before you check anything in the engine com­
partment,
always r ea d and heed all W ARN­
INGS
¢ A in Working in the engine compart­
ment on page 216.
• Read the brake fluid leve l from the brake
fluid reservoir
¢ fig. 173. The brake fluid
l evel must be between the
"MIN" and
"MAX" markings .
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
co page 218.
The fl uid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
I f the b rake fluid level falls
considerably be­
l ow the "MIN" mark, the brake wa rning/indi ­
cator light- (U.S.
models) ;II (Canadian
models) will come on
¢ page 14. Do not con ­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized Audi dealer or other quali­
fied fac il ity and the cause corrected. If the
brake fluid level is too low, the brake warn ing/
i ndicator light w ill illuminate. Contact an au­
thor ized Audi dealer
imm ediatel y.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moistu re from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
dec rease braking per formance.
Therefore, the brake flu id must be changed
ev ery tw o y ear s. Always use new b rake fluid
which confo rms to Fede ral Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id rese rvoi r can be difficult to
r each, therefo re , we re commend that yo u
have the brake fl uid changed by yo ur a utho r­
ized
Audi dealer. Your dea ler has the correct tools, the
right brake flu id and t he know -how
to do this for you.
A WARNING
-- Brake flu id is poisonous. It must be stor-
ed only in the closed or igina l container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
spe cifi cation
J 17 03 and conforms to
Federa l Motor Vehicle Standard 1 16 .
Always chec k with your authorized A udi
dealer to make sure yo u are using the
correct brake fluid. The cor rect type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi­
c iency of the brakes as well as your
safety . T h is i:ou ld result in an ai;i;ident.
(D Note
Brake fluid will damage the pai nt of you r
vehicle .
@ For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired and the necessary expertise, we
r ecommend that yo u have the brake flu id
changed by yo ur autho rized Aud i dea le r.
Battery
General information
Under normal operat ing cond itions, the bat­
te ry in your Audi does not need any ma inte­
nance. With
high outside temperatures or
long da ily drives we recommend that you have
the e lectrolyte leve l che cked by a se rv ice fa­
c il ity. The electroly te leve l should also be
chec ked each time the battery is cha rged

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tively small patch of rubber on each tire that
assures that a ll- important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry more weight than they can safely han­
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage i nclud­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
A vo idin g damage
If you have to drive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
i nstall them .
When removed, the wheels or t ires should be
sto red in a cool, dry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .
Tires an d wheel s 231
New tires
New ti res have to be broken in¢& .
The tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
patte rn.
H idden damage
Damage to tires and r ims is often not readily
visible . If you notice unusual v ib rat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au­
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar­
rows on the sidewa ll, that po int in the direc­
tion the t ire is designed to rotate. You must
f ol low the specified di rection of rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information ¢
page 258.
A WARNING
New tires or t ires that are o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in. To reduce the r isk of losing
control, a co llision and ser ious personal
in ju ries, d rive with special ca re for the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowout and sudden de­
fl ation, cras hes and se riou s personal in­
juries . Have worn or damaged t ires re­
placed immediate ly.
- Tires age even if they are not being used
and can fai l sudden ly, especially at hig h
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

-The brakes o n a vehicle t hat has been
overloaded may not be a ble to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
trol and a crash.
- Always make sure that the tota l load be­
ing transported -including the we ight of
a tra ile r hitch and the tongue weight of a
loaded trailer - does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cl e Weight Rating.
A WARNING
- Incorrect tire pressures and/or underin­
fla tion can lead to a serious o r fatal acci­
dent.
- Incorrect tire pressures and/or underin­
fla tion cause increased tire wea r and can
affect the handling of the vehicle .
- Incorrect tire pressures and/or underin­
flation can also lea d to sud den tire fa il­
ure, incl uding a blowo ut and sudden de ­
flation, causing loss of vehicle control.
Checking tire pressure
.
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure Lobel located on driver's side 8-pil­ lor.
The re commended t ire press ures a re o n the
tire pressure label and in the tab le
c=> page 235, Cold tire inflation pressure. This
means that the pressure must be checked and
adj usted when the tire has not been driven for
more than a couple of m iles (kilometers) at
low speeds during the previous three hours .
A ir i n the tires expands when the tire heats up
as a result of inte rnal fr iction as it flexes in
use. The t ire p ress ure is higher w hen the tire
h as wa rmed up th an when it is "cold."
It is the inflat io n pressu re in a "cold" tire that
counts. Therefore, you shou ld never let air out
of a warm t ire to ma tch "Cold tire in flation
p ressu re" recommend ations

tires wo uld then be unde rinflated and co uld
fail suddenly.
T he tire pressure label on your Aud i lis ts the
re commended co ld tire inflation pressures at
maximum capacity for the new, orig inal
equipment tires that were on your ve hicle at
the time it was manufactured. For the loca­
tion of the labe l
c::> page 235, fig. 176.
Most tires lose air naturally over t ime. They
can a lso lose some air if yo u drive over a pot­
ho le or hit a curb while par king. It is usually
not possible to see whether the rad ia l tires
u sed today are underinflated just by looking
at them .
There fore, be sure to check t ire p ress ures at
l east once a month and always before going
on a long tr ip. Make sure to take the n umber
of peop le and the amount of luggage into ac ­
count when adjust ing tire pressure for a tr ip -
even one that you wou ld not conside r to be
"long." See
c::> page 239, Tires and vehicle
food limits
f or mo re import ant inform ation .
Always use an accurate ti re pressu re gauge
when checking and ad justing inflation pres­
s ur es. Check a ll of t he tires and be s ure not to
forge t the spare tire.
If the pressure in any t ire
is too high when the ti re is "cold," let air out
of the ti re s low ly with the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and k ind of
driv ing you plan to do.
If the pressure in any ti re is too low, note the
difference between the pressure in the co ld
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the ve hicle load (passengers and luggage) for
the tires on you r veh icle as listed on the on
you r vehicle and in this ma nual and the kind
of d rivi ng you plan to do .
Never exceed th e maximum inflation pr es­
sure listed on the tire sidewall for any rea­
s on.

@ For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle control, but can a lso damage importan t pa rts of the
ve hicle and can lead to s udden tire failure, in­
cluding a blowout and sudden deflation that
can cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making s ure that load limits are
not exceeded . Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are technica lly referred to as the
vehicle's
Gross Veh icle We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory insta lled accessories, a full
tank of f ue l, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is intended to carry ("seating capacity") with an
assumed weight of 150 lbs (68 kg) for each
passenger at a des ignated seat ing pos ition
and the total we ight of any l uggage in the ve­
hi cle. If you tow a trailer, the weight of the
trailer hitch and the tong ue weight of the
loaded trailer must be included as part of the
vehicle load.
The
Gro ss Axl e W eight R ating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating a re listed on the
safety compliance sticker labe l located on the
driver's side B -pillar . Your A udi has 4 seating
positions, 2 in the front and 2 in the rear for
total seating capacity of 4. Each seating pos i­
tion has a safety belt¢
page 128, Safety
belts .
Tire s an d wheel s 239
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car ­
ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers w ho are
heavier than the standard we ights assumed
mean that less we ight can be ca rried as lug­
gage.
The tire pressure label on your Aud i also lists
the maximum combined weight of a ll of the
occupants and luggage or other cargo that
the ve hicl e can carry . For t he locat ion of the
label¢
page 235, fig . 176.
.&_ WARNING ~
Overloading a vehicle can cause loss of ve -
h icle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry wi ll prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been over load­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash .
- Always make sure that the total load be­
ing transported -includ ing the weight of
a t railer hitch and the tongue we ight of a
loaded trailer - does not ma ke t he vehi­
cle heavier than the vehicle's G ross Vehi­
cle Weight Rating.

242 Tires and wheels
& WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of control.
- Always keep chemicals that can cause tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .

T he tires and rims are essential parts of the
vehicle 's design . The tires and rims approved
by Audi are spec ially matched to the charac­
teristics of the vehicle and can make a major .,..

Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time
and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
deri nflated.
- For technical reasons it is not always
possible to use wheels from other vehi­
des -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat, increasing stopping distances and caus­
ing a collision.
- Run flat tires may only be used on vehi­
cles that were equipped with them at the
factory. The vehicle must have a chassis designed for run flat tires . Incorrect use
of run flat tires can lead to vehicle dam­
age or accidents. Check with an author­
ized Audi dealer or tire specialist to see if
your vehicle can be equipped with run flat tires. If run flat tires are used, they
must be installed on all four wheels. Mix­
ing tire types is not permitted.
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
Tires and wheels 245
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible .
- Never drive without the valve stem cap .
The valves could get damaged.
@) For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
' Uniform tire quality grading
-Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
c:> page 242,
fig. 180.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (11/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how­
ever, and may depart significantly from the
norm due to variations in driving habits, serv­
ice practices and differences in road character-
istics and climate. .,.. •

248 Tire s and whee ls
Where snow chains are mandatory oncer­
tain roads, this normally also applies to ve­
hicles with a ll-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled rims . If different rims are fit­
ted, the correct wheel bolts with the r ight
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r=> page 275.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
er ly t ightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out w hen the veh i­
cle is moving. If the tighteni ng torque is
too high, the whee l bolts and threads can be damaged and the whee
l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque whee l bolts diago­
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w it h low aspect
ratio tires. These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi ­
t ions . Ask your author ized A udi dealer for
more details.
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage. Conven­
t iona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-aspect -ratio tires is
particularly sens iti ve to imp roper inflation
pre ssure. It is therefore important that low
a spect ratio tires ar e inflat ed to the specified
pre ssure and that the inflation pressure i s
r e gularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
m onth and alw ays bef ore a long trip
r=> page 237, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be d amaged more
easily by impact with potholes, curbs, gull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.

254 What do I do now?
-Never st ore the inflatable spare tire or
jack and tools in the passenger com­
partm ent.
- Always s tore a ll jacking equipment,
too ls, and the inflatable spare tire in
the luggage compartment.
- Tighten the knurled retaining screw for
the inflatable spare tire securely.
Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel .
