Sporty driving
Warming up and cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv ­
ing.
When warming up, the vehicle is driven at a maximum engine speed of
6000 RPM
(Vl0 engine) or 7000 RPM (V8 engine) in or­
der to raise the engine oil temperature to a minimum of
140 °F (60 °(). The tires also on­
ly reach their full road holding capability once
they have warmed up .
The cooling fan can continue to run in your ve­ h icle after the engine is switched
off. H owev­
er, driving the vehicle to cool it down is part ic ­
ularly important. During sporty driving, the
engine and brakes, the exhaust system, and
the t ransm ission all become ex treme ly hot.
Before you park the vehicle, you shou ld d rive
it for a few mi les/kilometers at light load in
the low rpm range to allow it to coo l down .
Driving on a track
Before you take your vehicle out on a track,
ensure that it is in perfect condition. For ex­
ample, you should check the tire tread and the brake pads . It is best to increase t ire pressure
by about 0 .3 bar .
When driving on a track, oil consumption may be somewhat higher than in "normal" opera­
tion ¢page
180.
You shou ld definitely inspect your vehicle af­
ter subjecting it to severe condit ions. Are the
brake pads OK? Is there anything unusual
Dri vin g and en vironm ent 159
about the ti res, including the inner and outer
sidewa lls (e.g . tread, blistering)? Are the air
intakes free of leaves and tire dust? Is the o il
l evel OK?
Your authorized Audi dea ler or qua lified work­
shop will be happy to undertake an inspection
before and after use on the race track.
(D Tips
- Some race tracks (e.g . steeply banked
t u rns) may affect the response of the
ESP .
- When driven on a race track, all vehicle
parts are severe ly stressed. This can re ­
sult in increased wear.
Operation and maintenance
Fuel economy, env ironme nta l impact, and
wear on your eng ine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
By having your ve hicle reg ularly se rv iced by an
authorized Aud i dea ler helps to ens ure that i t
r uns properly and econom ica lly. The condition
of your veh icle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
con sumptio n.
The amount o f oi l used is re lated to engine
load and speed .
It is normal fo r the oil consump tion of a new
engine to reac h its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 mi les
(5,000 kilometers) before you can p rope rly
assess oil consumpt ion.
This also app lies to fue l cons umption and en­
gine output.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting specifi­
cations. This engine needs the right kind of
engine o il that meets spec ificat ions regarding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l
and changing oil w ith in the time a nd mileage
interva ls printed in your vehicle's Warranty
&
Maintenance book let matters a lot more to ­
day than it did yea rs ago. A udi has developed
a special quality standard for engine oil that
will help assure that your veh icle's eng ine will
get the lubrication it needs for proper opera­
tion .
Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
b rication that can outlast traditiona l petrole ­
um-based o ils, making them a smart choice
for use throughout the life of you r A udi .
Whether you use synthetic or petroleum­ based engine oil, the oil that you use must
conform to Audi's oil qual ity standard
VW 502 00 to help keep your veh icle 's eng ine
r unning smoo thly and help prevent t he fo r­
ma tion of harmfu l deposi ts, some times called
"s ludge," that over t ime can lead to expensive
repairs.
A t the time of pr intin g, engine o ils availab le in
the U .S . and Canad a that meet the exact ing
specifications o f A udi oil standard VW 502 00
are synthetic engine oils . This does not mean,
however, that eve ry synthetic engine oil wi ll
meet A udi oil standard VW 502 00. So a lways
be sure that you use an approved o il.
To help preve nt the formation of harmful de ­
posits use only oi l with the fo llow ing spec ifi ­
cations printed on the oil container :
Audi oil standard VW 502 00
Oil container labels may car ry the specifica ­
tion sing ly or in combination with othe r desig ­
nations and oil quality standa rds .
Viscosity
Engine o ils are graded accord ing to their vis­
cosity . Th e pr oper viscos ity grade oil fo r you r
engine de pends on clim actic o r seaso nal con­
di tions where yo u drive. You can use o il wit h a
viscosity grade o f SAE SW40 across all tem ­
perature ranges for norma l driving conditions.
However, if engine oil visco sity g rade SA E
SW40 is not ava ilable, you can a lso use v iscos­
ity grade SA E SW -30 or SA E OW -40 as long as
it meets Audi oil q ua lity standard VW 502 00
specificat ions.
Beca use engine o il that mee ts the Audi o il
standard may not be availab le everywhere
when you need it, we strong ly recommend
t h at you a lways carry with you an extra quart
( li ter) of oil that express ly conforms to the
VW 502 00 specification, in case you have to
top off the oil while on the road .
Only if the level of the oil is at or be low the
min imum ma rk on the o il dipstick - and n o oi l
that expressly conforms to Audi o il standard
VW 502 00 specifications is availab le -may
yo u top off with a high quali ty engine o il, p ref­
erably synthet ic-based, that me ets ACEA A3,
AC EA AS o r AC EA B S or A PI SL spec ifi cat io ns,
but even t hen, only in v iscosi ty g rades SA E
SW -40, SA E SW-3 0, or SAE OW-40 . However,
during the entire time between oi l change in ­
te rva ls , never top
off with more than a tota l
of 0 .5 qt/liter engine oil that does not con­
form to Audi oil specification VW 502 00.

Changing the engine oil

The engine oil and oil filter must be changed
according to the mi leage (kilometers) and
time interva ls specified in your vehicle's War­
ranty & Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine o il can reduce engine performance and
can lead to expensive engine repairs.
Changing the o il at the recommended inter­
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use . If you are not sure when
you have your oi l changed, ask your author­
i zed A udi Service Advisor.
Under some circumstances the engine o il
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, ope ra te the vehicle in dusty
areas or mostly under s top-and-go traffic con­
d itions, or when yo u use your vehicle whe re
temperatures stay below freezing point for
l ong periods.
D etergen t additives i n the o il w il l make fresh
oil look dark after the eng ine has been run ­
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
Damage or malfunction s due t o lack of
m aintenance
It is essen tial that you change your oil at the
r ecommended inte rva ls using only engine o il
that complies with A udi oil standard
VW 502 00. Yo ur Limited New Vehicle War ­
ranty does not cover damage or malfunctions

Engine 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
cooling of interna l eng ine components, all in ­
te rnal combust io n engines consume a certain
amount of oil. Oil consumpt io n va ries from
engine to e ngine and may change sig nifican tly
ove r the life of the engine. Typically, engines
with a spec ified break -in pe riod (see
c::> page 158) consume more oil d uri ng the
break-in pe riod than they consume afte r oi l
consumption has stabilized.
U nder normal cond itions, the rate of oi l con ­
s u mption depends on t he q uality and viscos ity
of the oil, the RP M (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
condensa tion or fue l residue a nd the oxida­
tion level of the oil. As any eng ine is subject to
wear as m ileage builds up, t he oil co nsump­
t ion may increase over time until repla cement
of wo rn components may be come necessary.
Wi th a ll these va riab les coming into p lay, no
standard rate of oil consumpt io n can be es­
t a bl is h ed o r spec ified . There is no alte rnative
to regular and frequent chec king of the o il lev ­
el, see
Note.

Engine cooling system
Coolant
The coolant provides cooling for the engine.
The percentage of the coolant additive deter­
mines the freeze protection of the coolant in the winter.
The cooling system has been filled at the fac ­
tory with a permanent coo lant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly­
col-based coolant additive Gl2++ ant ifreeze
with ant icor rosion add itives (SO% fo r USA
models; 60% for Canad ian models).
Checkin g and fillin g 181
Coolant additive
The percentage of the coo lant add itive de­
pends on the climatic cond itions in wh ich the
vehicle is operated . If the percentage of
freeze protection i n the coo lant is too low, the
coolant can freeze, leading to a failure o f the
cooling and heating circuit.
T he percentage of coolant addit ive has al­
ready been adjusted at the factory for the ve­
hicle's climatic conditions.
T he m ix rat io for USA models is SO% wa ter
and SO% coolant addit ive, for Canadia n mod­
els 40% water and 60% coolant additive. This
mixture both ass ures the necessary frost pro ­
tection (-31 °F/-3S °C for USA models, -40 °F/-40 °C for Canada models) a nd protects
metal components i n the engine's cooling sys ­
tem from corrosion and scaling. It also ra ises
t h e boili ng poi nt of the coo la nt.
Summer time
Do not reduce the concentrat ion of the cool­
ant in the summer by adding p la in water.
The
proportion of coolant additive must be at
least 50 % but not more than 60 %
to main­
ta in an tifreeze pro te cti on and cooling eff ic ien­

A WARNING
- The cooling system is under press ure. Do
not open the cap of the coolant expan­
sion tank when the eng ine is hot. You
risk being scalded .
- The coo lant add itive, and therefore the

With a major loss of coolant, you shou ld add
the coolant only when the engine has
cooled.
In this way you prevent engine damage.
A WARNING
- The cooling system is unde r pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by followi ng
these steps .
- Turn off t he engine and allow it to coo l

196 Tires and wheels
wheels you have to adjust the tire pressures
on all wheels.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RI] appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability .
- Incorrect tire pressures and/or underin­ flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle .
The applicable pressure values are locat­
ed on a sticker on the driver's side 8-pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure monitoring system can work cor­
rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
the function of the tire pressure monitor­
ing system .
- Always inflate tires to the recommended
and correct tire pressure before driving
off .
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the tires will wear prematurely and the
vehicle will not handle well. -
If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the tire pressure and add
air as required .
(D Note
Driving without valve stem caps can cause
damage to the tire valves. 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
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any tire can carry .
A vehicle that is overloaded will not handle
well and is more difficult to stop. Overloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire failure, in­ cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle . These
load limits are technically referred to as the
vehicle 's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus
maximum load. The maximum load includes

A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in­
structions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
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 neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to ve­
hicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel 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 .
Tires and wheels 205
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 211.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal 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 vehi­
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 wheel 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 wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
ized Audi dealer or qualified workshop.
