Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather condit ions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
drive r inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road during ex treme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

8_ WARNING
-New brake pads don't have the best stop­
ping power and must be "broken -in" dur ­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal city driving .
The break-in period can be considerably
longer for vehicles with ceramic brake ro­
tors*. You can compensate for this by pressing the brake pedal more firmly.
This also applies later when new pads are
installed.
- You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and diminish braking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned
off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct- ed
. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est authorized Audi dealer or qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance.
Electro-mechanical
power assist, dynamic
steering
The electro-mechanical power assist helps
the driver when steering .
Power steering adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defective! Do not drive vehicle!
If this indicator light turns on and stays on
and this message appears, the power steering
may have failed.
Do
not continue driving . See your authorized
Audi dealer or other qualified repair facility
for assistance .
''!'Y Dynamic steering: System fault! You can
continue driving
If the indicator light turns on and the mes­
sage appears, the steering may be more diffi­
cult to
move or more sensitive than usual. The
steering wheel may also be at an angle when
driving straight .
Drive slowly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected. .,..

';'ij Dynamic stee ring : initi alizing
If th is driver message appears and the ind ica­
tor light is flash ing on the inst rument pane l,
dynamic steering* is be ing reinitialized. Once
you start the engine after this is finished, the
steering whee l wi ll be easy to move. Re-initi­
alization m ight be necessary if the steering
wheel was moved hard to the left and r ight
while the veh icle was not moving. The display
goes out as soon as initialization is complete .
A WARNING
Have the dynamic steering* system mal­
function repaired as soon as poss ible by an
authori zed Audi dealer or any qualified
workshop -risk of accident!
@ Tips
- If the . or 1~ ij indicator light only stays
on for a short t ime, you may continue
driving.
- The dynamic steering* stability systems
are not available in the event of a system
malfunction.
- For additional informat ion on dynamic
stee ring*, refer to
c::> page 104.
Driving with your
quattro ®
With all-wheel drive, all four wheels are driv­
en.
G ene ral inform ation
W ith all -whee l dr ive, power is distributed to
all fo ur wheels. This happens automatica lly
depending on your driving sty le and the road
conditions at the time . See also
c::> page 176.
A center diffe rent ial distr ibutes the dr iv ing
power variably to the front and rear axle.
It
works together with se lective wheel torque
control, which activates when driving through
curves
c::> page 177. W ith the sport d ifferen ­
tial*, power distribution to the rear wheels is
variable and can be adjusted with drive select
<=:> page 104 .
Intellig ent technolog y 181
The all -whee l drive concept is designed for
high engine power. Your vehicle is exception­
ally powerfu l and has excellent driving charac­
teristics both under normal driv ing cond itions
and on snow and ice. Always read and follow
safety precaut ions
c::> ,&. .
Winter t ires
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even w ith
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak ­
ing: these tires must be mounted on
a ll fou r
wheels. See also c::> page 23 7, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to veh icles
with all -wheel drive
c::> page 238, Snow
chains .
Replacing whee ls / tires
Vehicles with a ll-wheel drive must always
have tires of the same s ize. Also avoid tires
with different tread depths. For deta ils see
page
~ page 233, New tires and replacing
tires and wheels .
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle. It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
~ page 184.
A WARNING
Always ad just your dr iv ing to road and t raf­
fi c condi tions. Do no t let the extra safety
afforded by all-wheel drive temp t you into
taking extra risks.
- Al tho ugh t he all-wheel drive is very ef­
fective, always remember that braking capacity is lim ited by tire traction . You
should therefore not d rive at excessive
speeds on icy or slippery road surfaces.

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
""Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
"" Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which cou ld result in over-
Driving and environment 187
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
au thorized Aud i dea ler helps to ensure that it
runs properly and economic all y. The condition
of your veh icle not on ly affects its safety and
ability to hold its va lue, it a lso affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents .

Your authorized Audi dealer has a variety of
dedic ated veh icle-car e products and can ad ­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro­
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 189
- Moisture and ice on brakes may impair
brak ing effic iency¢
page 178. Test the
brakes carefully each time you wash the
veh icle.
@) For the sake of the environment
Select on ly environmentally friend ly clean­
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .

-
-Never clean the instrument panel or the
surface of airbag modules with cleaning
products that contain solvents .
- Products containing solvents will make
the surface of this part porous.
- Serious injuries can result if plastic parts
come loose when the airbag is deployed.

Natural leather
App lies to vehicles: with natura l leather
Audi makes great efforts to maintain the
properties, natural look and feel of interior
leather.
General
We offer many different types of leather on
our vehicles. Most are different types of nappa
leather, which has a smooth surface and
comes in various colors.
The intensity of the color determines the visu­ al characteristics and appearance. If the sur­
face of the leather has a typical natural look,
then the leather is a nappa leather that has
been left in a relatively natural condition. This
leather offers particularly good comfort and
breathes well. Fine veins, closed grains, insect
bites, skin folds , and subtle variations in color
remain visible. These characteristics demon­
strate that the material is natural.
Natural nappa leather is not covered by a col­
or finish.
It is therefore more sensitive to soil­
ing and wear, which is something you need to
consider if children, animals or other factors
might prove to be particularly hard on the
leather. By contrast, leather types that are covered by
a colored finish layer are more durable.
This
has a positive effect on the leather's resist­
ance to wear and soiling in daily use. On the
other hand, the typical characteristics of natu­
ral leather are barely or not apparent . Howev ­
er, this does not mean that the leather itself
is of inferior quality .
Care and handling
Because of the exclusive nature of the types of
leather that Audi uses and their unique prop­
erties (such as sensitivity to oils, grease, soil­
ing, etc.), you will need to be somewhat care­
ful with these leathers, and a certain type of care is required . For example , dark clothing
materials can discolor leather seats (especial­
ly if such clothing is damp and was not dyed
correctly). Dust and dirt particles in pores,
folds, and seams can have an abrasive effect
and can damage the leather surface as well as
weaken seams.
The leather should be cleaned regularly as
needed. After having been used for a relatively
long time, your leather seats will acquire a
rich aged finish. This is a characteristic of nat­
ural leather and a sign of true quality.
In order to maintain the value of this natural
product over the life of your vehicle, you
should follow the recommendations below:
(D Note
- To keep your leather from bleaching out,
do not allow it to be exposed to bright
sunlight for long periods of time. If you
have to leave the vehicle parked outside
for long periods, cover the leather to
protect it from direct exposure to sun­
light.
- Sharp objects on clothing, such as zip­
pers, rivets or sharp pieces on belts can
leave permanent scratches or scrape
marks on the surface of the leather.
(D Tips
-After each time you clean the leather and
at regular intervals, use a leather

Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi .
Whether you use synthetic or petroleum ­
based engine oil, the oil that you use must
conform to Audi 's oil quality standard
VW 502 00 to he lp keep your vehicle's engine
running smoothly and help prevent the for­
mat ion of harmfu l deposits, sometimes called
"sludge ", that ove r time can lead to expensive
repairs .
At the time of pr int ing , engine o ils available in
the U .S . and Canada that meet the exacting
specifi cations of Audi oi l standard VW 502 00
a re synthetic engine oils. This does not mean,
however, that every syn thetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the format ion of harmful de ­
posits use only oi l with the fo llowing specifi­
cations printed on the oil container :
Audi oil standard VW 502 00
O il container labe ls may carry the specif ica ­
tion s ingly or in comb inat ion with other des ig­
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis­
cosity. The proper viscosity grade oil for your
engine depends on cl imactic or seasonal con­
d itions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem ­
pe ratu re ranges for normal driving conditions .
However, if eng ine o il viscos ity grade SA E
SW40 is not avai lab le, you can also use viscos­
ity grade SAE SW -30 or SAE OW-40 as long as
it meets Audi o il quality standard VW 502 00
specif ications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an ext ra quart (
li te r) of oil that exp ress ly con forms to the
VW 502 00 spec ification, in case you have to
top
off the oil while on the road.
Only if the level of the o il is a t or be low the
min imum mark -and no oi l that expressly
conforms to Audi oil standard VW 502 00
specifications is available - may you top
off
with a high quality engine o il, preferab ly syn ­
thet ic-based, tha t mee ts ACEA A3 or API SM
specifications, but even then , only in v iscosity
grades SAE SW-40 , SAE SW-30, o r SA E

Changing the engine oil
The eng ine oi l and oil fi lter must be changed
according to the mileage (kilometers) and
time intervals specified in your ve hicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil ca n reduce eng ine performance and
can lead to expensive engine repa irs .
Changi ng the oil at the recommended inter­
vals is so very important because the lubricat­ ing proper ties of oil decrease gradually during
norma l veh icle use . If you are not sure when
you have your oil changed, ask your author­ ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
shou ld even be cha nged more frequent ly .
Change oil more often if you drive mostly
sho rt distances, operate the ve hicle in dusty
areas o r most ly unde r stop-and-go t raff ic con-
di tions, o r when you use your vehi cle where .,..

214 Checking 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-basedcoolant additive G13 antifreeze with
anticorrosion add itives (50% for USA models;
60% for Canadian models). This mixtu re 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 eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 S °C) USA
- -40 °F ( - 40 °C) Canada .
_&. WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~
A in Working in the engine
compartment on page 207.
(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- crease the
proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using on ly coolant ad­
ditive G12++ or G13 for your vehicle.
This coolant additive is availab le at au­
thor ized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro­
sion cah cause a loss of coolant and se­
rious engine damage.
- Do not add any type of rad iator 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 Veh icle
Limited Warranty.
· Checking the engine coolant level and
adding coolant
Be very careful when adding engine coolant.

Radiator fan
The radiator fan switches on automatically by
itself.
The radiator fan is dr iven by the engine via the
V-be lt . T he viscous clutch regulates the speed
of the fan accord ing to the temperature o f the
coolant .
A n auxiliary e lectr ic radiator fan* switches on
and off depending on coolant temperature
and other vehi cle operating conditions.
After you switch the engine off, the auxiliary
fan can cont inue runn ing for up to 10 minutes
- even with the ignition off.
It can even sw itch
on again later by itself

- To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
contro lled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper ­

Because tec hnical changes may be made to
ve hicl e equ ipment dur ing the model yea r, a l­
ways compare the tire s ize designation on the
tire pressure label on your vehicle w ith the
tires on your vehicle . Make s ure that the tire
size information on the vehicle label is the
same as the s ize of the t ires on the vehicle.
This is especially important if the vehicle be­
longs to someone else or you bought the veh i­
cle with different rims/tires or you bought the
veh icle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
load limits are not exceeded . Vehicle load in­
cludes everybody and everything in and on the
ve hicl e. These load limits are technically refer­
r ed to as the vehicle's G ross Vehicle We ight
Rating ("GVWR"). The Gross Ax le Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles .
The Gross Vehicle We ight Rating and the G
ross Ax le Weig ht Rating are listed on the
sa fe ty comp liance sticke r label lo cated on the
dr iver's side B-pillar . The tire pressu re labe l on
your A udi lists the maximum combined
weight of all of the occ upants and luggage o r
other cargo that the veh icle can carry. For the
location of the t ire pressure label ¢

A WARNING
-Overloading a vehicle can cause loss of ve-
h icle contro l, a crash or other accide nt, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly a nd in­
crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
