D am age or m alfunc tions du e to lack of
m ainten ance
It
is essential that you change your oil at the
recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cool ing of internal engine components, a ll in­
ternal combustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to wear as mi
leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see
Note .
If
the yellow engine oil leve l warning symbo l
I! in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le

- Observe and follow legal regu lations
when disposing of empty oil containers.
Changing the engine oil
We recommend thot hove 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 ¢ & in Working in the engine compart­
ment on page 216.
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 gradually during normal vehicle use .
Under some circ umstances the engine oi l
should be changed more frequently . Change
oil more often if you drive mostly short dis­
tances, operate the vehicle in dusty areas or under predominantly stop-and -go traffic con ­
d itions, or have your veh icle where tempera­
tures remain below freez ing fo r extended pe­
riods.
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing fo r a short time. This is norma l and is not
a reason to change the oil mo re often than
recommended.
Because of the problem of proper disposal ,
a long w ith the special tools and necessary ex­
pertise required, we strong ly recommend that
you have your o il changed by an authorized
Audi de ale r or a qualified service station.
If you cho ose t o c han ge your oil yours elf ,
please note the following important informa­
tion :
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 plug with
your fingers, stay as far away as possible. Always keep your forearm parallel to the
ground to help prevent hot oil from run­
n ing down you r arm.
- Dra in 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 rea ch of childre n.
- Continuous contact with used eng ine o il
is harmfu l to your sk in. Always protect
your skin by washing oil off tho ro ughly
with soap and wate r.
@ Note
Neve r mix oil additives with your engine
oi l. These additives can damage your en­
g ine and adversely affec t you r A ud i L imit­
ed New Veh icle War ranty.
@ For the sake of the environment
- Before changing your oil, first make su re
you know where you can prope rly 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 o r down
sewage drains.
- Recycle used engi ne oil by taking it to a
used engine oil collection facility in you r
area, or contact a service station.

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 G13 antifreeze with
anticorrosion additives (50% for USA models;
60% for Canadian models). This mixture both
assures the necessary frost protection 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 cool­
ant in the summer by adding plain water.
The
proportion of coolant additive must be at least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system .
For year-round driving, antifreeze 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
¢ .&. in Working in the engine
compartment on page 216.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions . This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in-
Checking and filling 223
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G12++ or G13 for your vehicle .
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
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.

To obtain an accurate read ing, the eng ine
must be switched off .
The expans io n tank in you r vehicle is equipped
with an e lectr ic cool ant level sensor.
When the coolant level is too low, the warning light in the A uto-Check System

b link until you add coo lant and the level has
been restored to no rm al. Even though the re is
an e lec tric coolant level sensor, we s till rec ­
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolan t loss, the cool ­
i ng system should be inspected immedia tely
by your authorized A udi dealer. It is not
enough merely to add coolant.
I n a
s e aled system, losses can occur only if
the boiling poin t of the coolant is excee ded as
a result of overheating.
A WARNING
The cooling system is unde r pressure and
can get ve ry hot. Reduce the risk of sca ld­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to cool
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and ve ry carefu lly in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap .
- To avoid being b urned, do not spill ant i­
freeze or coolant on t he exhaust system
or hot eng ine parts. Unde r certain condi­
tions, t he ethy lene g lycol in engine cool­
an t can ca tch fire .
(D Note
Do not ad d any type of radiator leak sea l­
ant to your veh icle's engine coo lant. Add­
i ng radiator repa ir fluid may adverse ly af­
fect the funct ion and performance of your
cooling system and could result in damage not cove red by your New Veh icle L imited

(D Note
Driving without valve stem caps can cause
damage to the t ire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely
mounted on the valve .
@) For the sake of the environment
Underinflated tires will also 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 on ly lead to loss of vehicle contro l,
but can a lso damage important pa rts of the
ve hicle and can lead to sudden tire failure, in­
cluding a blowout and sudd en d eflation that
c a n cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are
not exce eded . Vehicl e load includes ev erybody
and everyth ing in and on the vehicle. These
load limi ts are techn ically referred to as the
vehicle's
Gross Vehicl e W eight Rat ing
("GVWR ").
The "GVWR" includes the we ight of the basic
vehicle, all fac tory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load . The maximum load includes
the number of passengers that the vehicle is
i ntended to ca rry ("seating capacity") with an
assumed weight of 150 lbs . (68 kg) for each
passenger a t a des igna ted seat ing pos ition
and the tota l weight of any l uggage in the ve ­
h icle. If you tow a trailer, the weig ht of the
trailer hitch and the tongue we ight of the
loaded traile r must be included as part of the
vehicle load .
The
Gro ss Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
Tire s an d wheel s 239
The Gross Vehicle Weight Rat ing and the
Gross Axle Weight Rating are listed on th e
safety comp liance sticker label located on the
driver's side B-pillar. Audi has 4 seat ing pos i­
tions, 2 in the front and 2 in the rear for total
seat ing capac ity of 4. Each seating position
has a seat belt ¢
page 134, Safety belts .
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 we ight of the
loaded tra ile r) is lim ited. The more passen­
gers in the vehicle or passe ngers w ho are
heavier than the standard we ights assumed
mean that less weight can be carried as lug­
gage.
T he tire pressure label on your Aud i also lis ts
t h e maximum combined weight of a ll of the
occupants and l uggage or other cargo that
the ve hicle can carry. For the location of the
l abel ¢

A 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 we ight than your veh icle
was des igned to carry will prevent the
ve hicle 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
ve hicl e with in a safe distance .
- Tires o n a vehicle that has been overload­
ed can fail suddenly, incl uding a blowout
a nd sudden defla tion, causing loss of
control and a crash .
- Always ma ke sure t hat the to tal load be­
i n g transpo rted - incl udi ng t he weight of
a trailer hitch and the tongue we igh t of a
loaded trailer -does not make the vehi ­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.

242 Tires and wheels
& WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious 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 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 .

driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this normally also applies to
vehicles 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 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
¢ page 275.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision 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
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while driving 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 wheels bolts on your
vehicle.
- Always maintain the correct tightening
torque for the wheel bolts 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 veh i- cle
is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi­
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work­
shop.
Low aspect ratio tires
Your Audi is factory -equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road feel
and handling under a variety of driving condi­
t ions . Ask your authorized Audi dealer for
more details .
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
tional tires have a height/w idth rat io of 60 or
more.
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure. It is therefore important that low
aspect ratio tires are inflated to the specified
pressure and that the inflation pressure is
regularly checked and maintained. Tire pres­
sures should be checked at least once a
month and always before a long trip
¢ page 237, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.
