236 Check ing and filling
Only if the level of the oi l is at or below the
minimum mark -and no oil that expressly
conforms to Audi o il standard VW 502 00
specifications is ava ilable - may you top off
with a high quality eng ine oil, preferably synÂ
thetic -based, that meets AC EA A3 or API SM
specif ications, but even then, only in viscos ity
grad es SAE SW-40, SA E SW-30 , or SAE
OW-40. Howeve r, during the en tire t ime beÂ
tween oi l change intervals, never top off with
more than a tota l of 0.5 qt/liter eng ine oi l
that does not conform to Audi oil specification
vw 502 00 .
F or more informa tion about engine oil that
has been approved for yo ur vehicle , please
contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834
or visit our web site at www.audiusa.com or
www.audicanada.ca . Here you will a lso find a
current list o f oils (manufacturers, brand
names etc .) that conform to Audi o il standard
vw 502 00.
Chang ing the engine oil
The engine oil and oi l filter must be changed
according to the m ileage (ki lometers) and
time interva ls specified in your vehicle's WarÂ
ranty
& Maintenance booklet. Do not exceed
these in tervals -harmful depos it s from old
engine o il can reduce engine performance and
can lead to expensive eng ine repairs .
Changing the o il at the recommended interÂ
va ls is so very important because the lubricatÂ
ing p roperties of o il decrease gradually during
norma l vehicle use. If you are not sure when
you have you r o il changed, ask you r autho rÂ
iz ed Audi Service Advisor.
Under some c ircumstances the engine o il
should even be changed more frequently .
Change oi l mo re often if you drive mostly
short d istances , ope rate the vehicle in dusty
a reas or mostly under s top-and-go tr affic conÂ
d itions , or when yo u use your vehicle whe re
temperatures stay below freezing point for l ong periods .
D etergen t add itives in the o il w ill mak e fresh
oil look dark after the eng ine has been run- ning for a sho
rt time. This is normal and is not
a reason to change the oil more often than
recommended.
Damage or malfunctions due to l ack of
maintenance
It is essentia l th at you c hange yo ur oil at the
r ecommended intervals usi ng on ly eng ine oil
that comp lies with Audi oi l standa rd
VW 502 00. You r Limited New Vehicle War Â
r anty does not cover damage or ma lf u nctions
due to failure to follow recommended ma inteÂ
nance and use requirements as set forth in
the Aud i Owner's Manual and Warranty
&
Maintenance booklet. Your dealer will have to
deny warranty coverage unless you present to
the dealer proof in the form of Service o r ReÂ
pair Orders that all scheduled maintenan ce
w as performed in a time ly m anner.
Engine oil consumption
The engine in your vehicle depends on an adeÂ
quate amount of oil to lubri cate and
cool all
of its moving por ts .
In order to p rovide effective lubricat ion and
c ooling of inte rna l eng ine compo nents, all i nÂ
tern al combust ion engines co nsume a cer tain
amount of oil. Oil consumpt ion varies from
engine to engine and may change significantly
over the life of the engine . Typically , engines
with a spec ified break-in period (see
¢ page 206) consume more oil duri ng the
break-i n period than they consume after o il
consumption has stabilized .
Under normal cond itions , the rate of oi l conÂ
s u mption depends on the q uality and viscos ity
of the oil, the RPM (revolut ions per minu te) at
which the engine is operated, the ambient
temperature and road conditions. Further facÂ
tors a re the amount of oil dilut ion from water
c o ndensa tion or fue l resid ue a nd the oxida -
t ion level of the oil. As any engine is subjec t to
wea r as m ileage b uilds up, the oil consump-
tion may increase over time until replacement of wo rn components may become necessary. ..,..
Page 239 of 318

With all these variables coming into play, no
standard rate of oil consumption can be esÂ
tablished or specified . There is no alternative
to regular and freq uent checking of the oi l levÂ
e l, see
Note .
If the ye llow engine oi l level war ning symbol
in the instrument cluster

a lw ays r ead and heed all WARNÂ
ING S
c:> &. in Working in the engine comportÂ
ment on page 232.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance booklet. This is very important
because the lubricating properties of oil diÂ
minish gradually dur ing normal veh icle use.
Under some circumstances the engine oil
should be changed more frequently. Change
oil more often if you drive mostly short disÂ
tances, operate the vehicle in dusty areas or
under predominantly stop-and -go traff ic con Â
d itions, or have your veh icle where temperaÂ
tures remain below freezing fo r extended peÂ
r iods.
Detergent additives in the o il w ill make fresh
oil look dark after the eng ine has been runÂ
n ing fo r a short time. This is norma l and is not
a reason to change the oi l mo re often than
recommended.
Because of the problem of proper disposal,
along w ith the special tools and necessary exÂ
pe rtise required, we strong ly recommend that
you have your oi l changed by an author ized
A udi dealer or a qualified service station.

240 Checking and filling
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro Â
tects the engine from freezing in the winter .
The cooling system is sealed and generally reÂ
quires little attention.
The cooling system has been filled at the facÂ
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 Â
col-based coolant additive Gl3 ant ifreeze
with anticorros ion add itives (50% for USA
models; 60% for Canadian models). This mixÂ
ture both assures the necessary frost protecÂ
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 of the coo lÂ
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to mainÂ
tain antifree ze protection and cooling efficienÂ
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the veh iÂ
cle heating and engine 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 you check anything in the engine
compartment, always read and heed all
WARNINGS
c:> &. in Working in the engine
compartment on page 232.
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cliÂ
mate conditions. This is especially imporÂ
tant if you live in a region where the w in- ter
is extreme ly cold . If necessary, inÂ
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant adÂ
ditive Gl2++ or Gl3 for your vehicle .
This coolant additive is available at auÂ
thorized Audi dealers. Other types of
antifreeze can significantly reduce corÂ
rosion protection. The resulting corroÂ
sion can ca use a loss of coolant and seÂ
rious engine damage.
- Do not add any type of radiator leak seal Â
ant to your vehicle's engine coolant .
Add ing radiator repair fluid may adverseÂ
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .

Before you check anything in the engine comÂ
partment,
always read and heed all WARNÂ
INGS c:> &. in Working in the engine compart Â
ment on page 232 .
Park your vehicle on a level surface .
.,. Switch off the ignition.
.,. Read the engine coolant level from the
coo lant expansion tank
c:> fig. 200,
c:> page 234. With a cold engine, the coolant
level should be between the "min" and
"max" markings. When the engine is warm, ..,
Page 243 of 318

the level may be slightly above the "max"
marking .
The location of the coolant expansion tank
can be seen in the engine compartment illusÂ
tration ¢
page 234.
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 coolÂ
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 scaldÂ
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 apÂ
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 condiÂ
tions, the ethylene glycol in engine cool Â
ant can catch fire .
Checking and filling 241
@ Note
Do not add any type of radiator leak sealÂ
ant to your vehicle's engine coolant. AddÂ
ing radiator repair fluid may adversely afÂ
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.

.,. Place a thick rag over the coolant expansion
tank ¢
page 240, fig . 200 and carefully
twist the cap counter-clockwise ¢&_ .
.,. Add coolant.
.,. Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 240, Coolant. We
recommend using only coolant additive G12+
+, G3 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. ExÂ
cess coolant will be forced out through the pressure relief valve in the cap when the enÂ
gine becomes hot.

260 Tires and wheels
-Vehicles with front-wheel drive experience
more tread wear on the front wheels comÂ
pared to all-wheel drive (quattro ®).
- Please rotate tires as shown
¢fig. 207.
- Extra care must be taken when rotating di-
rection-specific tires
¢ page 2 78.
Wheel balancing
The wheels on new vehicles are balanced .
H owever, various situations during everyday
driving can cause them to become unbalÂ
anced , resu lting in vibrations you can usually
feel through the steering wheel.
Unba lanced wheels must be rebalanced to
avoid excessive wea r on steering , suspens ion
and tires . A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect whee l alignment can cause excesÂ
sive tire wear, impair ing the safety of the vehiÂ
cle .
If tires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Vehicles with quattro® must always have ti res
of the same size, construction and tread type.
F or details see
¢page 203.
A WARNING
Sudden tire failure can lead to loss of conÂ
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indicaÂ
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydrop laning" 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 specia
l care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histoÂ
ry." Old used tires may have been damÂ
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

- Remove snow chains before driving on
roads not covered with snow to avoid
damaging t ires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into d irect conÂ
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if necesÂ
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension should
malfunction, do not mo unt or use snow
cha ins beca use the veh icle will be exÂ
tremely low. If you do drive with snow
chains on while the vehicle is at this levÂ
el, the snow chains might severely damÂ
age the wheelhouse and other parts of
the veh icle.
Where snow chains are mandatory oncerÂ
tain roads, this normally also applies to
veh icles with All 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 installed rims. If different rims are fitÂ
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
cor rectly .
In certain circumstances, you may not use
wheel bolts from a different vehicle - even if it is the same model
~ page 298.
A WARNING
Imprope rly tightened o r maintained wheel
bolts can be come loose caus ing loss of control, a col
lision and serio us personal inÂ
jury.
- Always keep the wheel bo lts and the
threads in the whee l hubs clean so the
wheel bo lts can turn easily and be propÂ
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driv ing if greased or
oiled, even if t ightened to the specified
torque.
- Only use wheel bolts that belong to the rim being installed .
- Never use different wheels bolts on your
veh icle.
- Always ma intain the correct tightening
torque for the whee l bolts to reduce the
risk of a wheel loss. If the tightening torÂ
que of the wheel bolts is too low, they
can loosen and come out when the vehiÂ
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be Â
come loose .
(D Note
The specified torque for the whee l bolts is
90
ft l b (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque whee l bolts diago Â
nally . After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an authorÂ
i zed Audi dealer or qualif ied workshop.
Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
