a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of

nance and use requ irements as set forth in
the Audi Owner's Manua l and Warranty
&
Maintenance book let . Your dea ler will have to
deny warranty coverage u nless you present to
the dea ler p roof in the fo rm of Serv ice or Re­
pa ir Orde rs that all s chedu led maintenance

Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
¢
page 199) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 229
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instrument cluster
II li ghts up, you
sho uld check the oil leve l as soon as possib le
¢
page 230. Top off the oil at your earliest
convenience ¢

A WARNING
Before you check anythi ng i n the engine
com partment, always read a nd heed all
WARNINGS¢ .&.
in Working in th e engine
c ompartment on page 225.
(D Note
D riving w ith an insufficient o il level is like­
ly to cause sever e damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil le vel. Do not
rely on it . Instead, check the oil level in
your engine at regu lar intervals, pref­
erably ea ch time you refuel, and always
before going on a long trip .
-If you have the impression yo ur engi ne
c ons umes ex ce ss ive amoun ts of o il, we
recommend that you consul t your Au di
de aler to have the cause of your concern
properly diagnosed . Keep in mind that
the accurate meas urement of o il con ­
sumption requires great care and may
take some t ime. Y our Audi dea ler has in­
struct ions about how to measure oil con­
sumption accurately.

• Park your vehicle on a level surface.
• Shut the engine off when it is warm.
• Switch only the ignition back on.
• Wait approximately two minutes.
• Select:
ICARI function button> (Car)* sys­
tems
control button > Servicing & checks >
Oil level.
• Check the oil level in the display c::> fig. 185.
Add engine oil if the bar of the oil level indi­
cator is near "min"
c::> page 230.
Depending on the way the vehicle is driven
and the operating conditions, oil consumption
can be up to 1/2 quart per 600 miles (0.5 liter
per 1,000 km) . Consumption may be higher
within the first 3,000 miles (5,000 km).
@ Tips
The oil level indicator in the MMI Display is
only an information display. If the oil level
is low, a minimum oil warning appears in
the instrument cluster. Add oil

A WARNING
-- While topping off, the oil must not come
in contact with hot engine parts -fire
hazard!
- The oil filler cap must be properly se­
cured to prevent oil from being sprayed
on the hot engine and exhaust system
when the engine is running -fire hazard!
- If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly.
(D Note
- Check the oil level using the MMI. If the
message
Please reduce oil level appears,
contact your authorized Audi dealer or
other qualified workshop to have excess
oil extracted if necessary.
-Audi does not recommend the use of oil
additives. They may damage the engine ..,_.

and adversely affect you r New Vehicle

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
par tment,
a lways rea d and he ed all WARN ­
INGS
~ &. in Working in the engine compart­
ment on page 225.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradua lly during normal vehicle 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 traff ic con­
d itions, or have your veh icle where tempera­
tures remain below freezing for extended pe ­
riods.
Detergent additives in the o il w ill make fresh
oil look dark after the engine 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 disposa l,
along w ith the special tools and necessary ex ­
pertise required, we strongly recommend that
you have you r oi l changed by an authorized
Audi de ale r o r a qual ified servi ce station.

A WARNING
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en- gine oil, let the engine cool down to the
touch.
- When removing the o il dra in p lug with
your fingers, stay as far away as possible. Always keep your forearm parallel to the
ground to help p revent hot oil from run­
ning down you r arm.
- Dra in the oil into a container designed
for this purpose, one la rge enough to
hold at least the tota l amount of oi l in
your eng ine .
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact wit h used eng ine o il
is harmful to your s kin. A lways p rotect
your skin by washing oil off tho ro ughly
with soap and water.
@ Note
Neve r mix oil additives with your engine
oil. These additives can damage your en­
g ine and adversely affec t you r Au di L imit­
ed New Vehicle Warranty.
@ For the sake of the environment
- Before changing your oil, first make su re
you know where you c an properly dispose
o f the used oil.
- Always dispose of used eng ine oi l proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open streams or down
sewage drains .
- Recycle used engine oil by taking it to a
used engine oil collect ion facility in your
area, or contact a service station.

232 Check ing and filling
Engine 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.
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 water and the manufacturer's gly ­
col-based coolant additive Gl3 ant ifreeze
with ant icorros ion add itives (50% for USA
models; 60% for Canad ian models). This mix­
ture both assu res the necessary frost protec­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration o f the coo l­
ant in the summer by adding plain water .
The
propo rtion of coolant add it iv e mu st be at
l eas t 50 % but not mo re than 6 0%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- - 40 ° F ( -40 °C) Canada.
A WARNING
Before yo u check anything in the engine
compartment, always read and heed all
WARNINGS
c:> &. in Working in the engine
compartment on page 225.
- Before winter sets in, have the coolant
checked to see if the coo lant addit ive in
your vehicle is suffic ient to meet the cli­
mate cond itions. Th is is especially impor­
tant if you live in a region where the w in- ter is extreme
ly cold . If necessary, in ­
crease the proportion of coo lant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend us ing only coolant ad­
d itive Gl2++ or G l3 (check the labe l)
fo r your vehicle. This coolant additive is
ava ilable at a utho rized Aud i dea le rs.
Other types of antifreeze can sign ifi­
cantly reduce corros ion protection. The
res ulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal ­
ant to yo ur vehicle's engine coolant .
Add ing radiator repair flu id may adverse­
ly affect the function and performance of
your cooling system and could resu lt in
damage not covered by your New Veh icle
Limited War ranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 1 87 Engin e compar tmen t: cover on t he coo la nt
expansio n ta nk
Before you check anyth ing in the engine com­
partment,
alwa ys read and heed all WARN­
I NGS c:> &. in Working in the engine compart ­
ment on page 225 .
.. Park your vehicle on a level surface .
.. Switch off the ignition.
.. Read the engine coolant level from the
coola nt expansion tank
c:> fig . 187,
c:> fig. 184 . With a cold engine, the coolant
level shou ld be between the "min" and
"max" markings. When the eng ine is wa rm, ..,.

the level may be slightly above the "max"
marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢ page 22 7.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System ¢page 16will
illuminate until you add coolant and the level
has been restored to normal. Even though
there is an electric 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
system. In the event of coolant loss, the cool­
ing 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 coolant is exceeded as
a result of overheating.
& 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 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 slowly and very carefully in
a counter-clockwise direction while ap­
plying light, downward pressure 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 certain condi­
tions, the ethylene glycol in engine cool ­
ant can catch fire .
Checking and filling 233
@ Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function 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 anything in the engine com ­
partment,
always read and heed all WARN­
INGS ¢ & in Working in the engine compart ­
ment on page 225 .
.,. Turn
off the engine .
.,. let the engine cool down.
.,. Place a thick rag over the coolant expansion
tank ¢ fig .
187 and carefully twist the cap
counter-clockwise ¢&_ .
.,. Add coolant.
.,. Twist the cap on again tightly.
Replacement engine coolant must conform to
exact specifications ¢ page
2 32, Coolant. We
recommend using only coolant additive G12+
+, G13 or in an emergency G12+. Do
not use a
different additive. In an emergency use plain
water until you can get the correct additive
and can restore the correct ratio. This should
be done as soon as possible.
If you have lost a considerable amount of
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
Always use new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot.

Unbalanced whee ls must be rebalanced to
avoid excessive wea r on steering, suspension
and tires. A wheel must a lso be rebalanced
when a new tire is installed .
Incorrect wheel alignment
Incorrect whee l alignment can cause exces­
sive tire wear, impairing the safety o f the vehi­
cle. If tires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop .
All-wheel d rive
Vehicles w ith quattro ® must always have tires

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l injury!
- Never drive a veh icle 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"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil , gasoline
and brake fluid away from t ires.
- Tires age eve n if they are not be ing used
and can fail suddenly, especially at high
speeds. T ires that are more than 6 years
o ld can only be used in an emergency
and then with spe cial care a nd at lower
s peeds.
- Never mount used ti res on yo ur vehicle if

@ Tips
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 of whee l bolts is matched to the
factory insta lled 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 f itted
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
<=> page 287.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can becom e 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 clea n so the
w heel bolts can t urn easily and be prop ­
erly t ightened .
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l 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 for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
Tire s an d wheel s 257
can be damaged and the whee l can be­
come loose.
(D 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) . Torq ue whee l bolts diago­
nally. After changing a whee l, the torq ue
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
You r Aud i is facto ry-equ ipped w it h low aspect
ra tio tires. These tires have been tho ro ughly
tested and been se lec ted spe cifically for you r
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or le ss in the tire's s ize
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage. Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-aspect -ra tio tire s is
particularly sens it iv e to improper inflation
pressure. It is therefore important that low
aspect ratio t ires are inflated to the specified
pre ssure and that the inflation pressur e is
regularly che cked and maintain ed. Tire pre s­
s ures should be checked at least on ce a
m onth and alwa ys before a long trip
¢ page 246, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damage d mo re
easily by impact w ith potholes, curbs, g ull ies
or ridges on t he road, partic ularly if the tire is
u nderinflated.
