@ For the sake of the environment
-Oil should never enter the sewer system
or come into contact with the ground .
- Pay attentio n to lega l requ irements
when disposing of empty oil containers .
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
a lways r ea d and heed all WARN­
ING S
r=>page 210.
The engine oil must be changed according to
the intervals specified in you r Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradua lly during norma l veh icle use.
Under some circumstances the engine oi l
should be changed more frequently. Change
oil more often if you drive most ly short dis­
tances, operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
ditions, or have your vehicle where tempera­
tures remain below freezing for extended pe­ riods .
Detergent additives in the oil will make fresh
oil look dark after the eng ine has been run­
n ing for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposal,
along w ith the special tools and necessary ex­
pertise required, we strongly recommend that
you have you r o il changed by an author ized
A udi de ale r or a q ual ified servi ce station.
If yo u choo se to c hang e your o il yo urse lf,
please note the following important informa­
tion :
.8, WARNING
To reduce the ris k of persona l injury if yo u
m ust change the engine oil in your veh icle
yourself : -
Wear eye protection .
- To reduce the risk of burns from hot en -
gine oi l, let the engine cool down to the
touch.
- When removing the oil drain p lug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from run­ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the tota l amount of oil in
your engine.
- Engine oil is poisonous. Keep it we ll out
of the reach of childre n.
- Continuous contact with used eng ine o il
is harmful to your sk in . Always protect
your skin by washing oil
off tho roughly
with soap and water.
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Aud i Limit­
ed New Veh icle Warranty.
@ For the sake of the environment
- Before changing your oil, first make sure
yo u know where you can properly dispose
of the used oil.
- Always dispose of used eng ine oil proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open st reams o r down
sewage drains.
- Recycle used engine oil by taking it to a
used eng ine oil collect io n fac ility in you r
are a, or contact a se rvice station.
coolant 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 genera lly re-
quires little attention. .,..

The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer's glycol-based coolant addi-
tive Gl3 antifreeze with anticorros ion addi ­
tives (50% fo r USA models; 60% for Canadian
models) . This mixture both assures th e neces­
sary frost protect ion a nd p rotects me tal com ­
ponents in the engine 's coo ling system from
corrosion and scaling.
It al so raises the boil­
ing po int o f the coo lant .
D o no t reduce the concentration of t he coo l­
an t in the summer by ad ding plain w ate r.
The
proportion of coolant additive must be at
lea st 50 % but not more than 60%
to main­
tain ant ifreeze protection and cooling efficien­
cy. If the coolant frost protect ion is too low ,
the coolant cou ld free ze and damage the veh i­
cle heating and eng ine cooling system.
F or yea r-round driv ing, antifreeze is added at
the facto ry for temperatures down to:
- -3 1 °F ( -3 5°C) USA
- -4 0°F ( -4 0°C) Canada.
If you must add coolant, use a m ixture of wa ­
ter and coolant addit ive. M ixing the coolant
addi tive wi th dist illed wate r is recom mend ed.

The brake f luid leve l mus t be be­
tween the "MIN" and "MAX " ma rkings.
The location of the brake flu id reservo ir can be
seen in the engi ne compa rtment illust ra ti on
¢ page 212 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the b rake pads . Thi s is not cause for alarm.
If the brake fluid level falls

tinue to operate the vehicle. The comp lete
brake system should be thoroughly checked
by an authorized A udi dealer or other quali­
f ied fac ility and the ca use corrected . If the
br ake fluid level is too low, the brake warning/
indica tor light w ill illuminate. Contact an au·
thor ized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid abso rbs moist ure from the air. If
the water content in the brake fluid is too
Che cking and Fillin g 219
high, co rrosion in the brake system may resu lt
after a period of time . The boiling point of the
brake f lu id will also decrease conside rably and
decrease braking performance.
T herefore, the brake fluid must be changed
eve ry two year s. Always use new brake f luid
which conforms to Federal Motor Veh icle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoi r can be difficu lt to
reach, therefore, we recomm end that you
have the brake fluid changed by your author­
i z ed
Audi dealer . Your dealer has the correct
tools, the right brake flu id and the know-how
to do this for you .
A WARNING
-
-Brake flu id is poisonous. It must be stor-
ed only in the closed or iginal containe r
out of the rea ch of children!
- Brake failure can resu lt from o ld or inap­
p rop riate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SAE
spec ificat ion
J 1703 and conforms to
Federa l Motor Ve hicle Standard 116.
Always check with your authorized Audi
dealer to make sure yo u are using the
cor rect bra ke fluid. The cor rect type of
brake f luid is also i nd icated on t he
brake f lui d rese rvoir.
- The bra ke flu id must be new. Heavy us e
of the brake s can cause a vapo r lock if
the b ra ke fluid is left i n the system too
l ong . This can se riously affect the effi ­
ciency of the brakes as we ll as your
safety . This co uld resu lt i n an accident .
(D Note
Brak e fluid will dam age the pa int of your
vehicle .
@ For the sake of the environment
Because of the p rob lem of proper disposal
o f bra ke fluid as well as the spec ial too ls
r equired and the necessary exper tise, we
recommend that yo u have the brake flu id
changed by yo ur authorized Audi dea ler.

236 Tires and wheels
unbalanced, resulting in vibrations you can
usually feel through the steering whee l.
Unbalanced wheels must be rebalanced to
avoid excessive wea r on steer ing, suspension
and tires . A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
I ncorrect wheel alignment can cause exces­
sive tire wear, impair ing the safety of the veh i­
cle. If tires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All-wheel drive
Vehicles w ith quattro must a lways have tires
of the same size, construction and tread type.
F or details see
<=> page 190 .
A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and ser ious persona l 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 t ires.
- Tires age even if they are not being 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 o f vehicle control.
New tires and replacing tires and wheels
New tires and wheels have ta 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
te ristics of the vehicle and can make a major .,..

24 2 T ire s and wheel s
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory installed rims . If different rims are fit­
ted, the correct wheel bolts with the right
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 270.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
c ont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop­ er ly t igh tened .
- 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 th e 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 wheel bolts diago­
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque w rench -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
ra tio 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 d riving 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 n umera l represents the ratio
of the tire's sidewall 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
pressure. It is therefore important that low
a spect ratio tires are inflat ed to the specified
pre ssure and that the inflation pressure i s
regularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
m onth and always bef ore a long trip
r=> page 231, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be d amage d more
easily by impact w ith potholes, curbs, gull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.

fall from a lift if there is a change in ve­
hicle weight distribution and balance.
This might happen, for example, when
heavy components such as the engine
block or transmission are removed .
- When removing heavy components like
these, anchor vehicle to hoist or add cor­
responding weights to maintain the cen­
ter of gravity. Otherwise, the vehicle
might tilt or slip off the hoist, causing
serious personal injury.
(D Note
- Be aware of the following points before
lifting the vehicle:
-The vehicle should never be lifted or
jacked up from underneath the engine
oil pan, the transmission housing, the
front or rear axle or the body side
members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear­
ance between the hoist and low parts
of the vehicle.
