know.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured .
T he Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3-and 6-year old children on
the passenger side and small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example , by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front passenger seat in child restraints that are list­
ed in the Standard .
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger side makes the front seat a potentially
dangerous place for a child to ride. The front
seat is not the safest place fo r a child in a for­
ward-facing child safety seat. It can be a very
Child Safety 173
dangerous place for an infant or a larger child
in a rearward-facing seat.
The vehicle's Advanced Airbag System has a
capacitive passenger detection system in the
front passenger seat cushion that can detect
the presence of a baby or a child in a child re­
straint system on this seat.
The capacitive passenger detection system
registers the changes that result in an electri ­
cal field when a child, a child restraint, and a
baby blanket are on the front passenger seat .
The change in the measured capacitance due
to the presence of a child, a child restraint,
and a baby blanket on the front passenger
seat is related to the child restraint system resting on the seat . The measured capacitance
of a child restraint system varies depending
on the type of system and specific make and
model.
The electrical capacitance of the various
types, makes, and models of child restraints
specified by the U.S.National Highway Traffic
Safety Administration (NH TSA) in the relevant
safety standard are stored in the Advanced
Airbag System control unit together with the capacitances typical of infants and a 1-year
old child. When a child restraint is used on the
front passenger seat with a typical 1 year-old infant, the Advanced Airbag System compares
the capacitance measured by the capacitive passenger detection system with the data
stored in the electronic control unit.
Child restraints and Advanced front
airbag system
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use with an airbag. Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in excep­
tional circumstances you must use it on the
front passenger seat, ca refully read all of the
information on child safety and Advanced Air-
bags and heed all of the applicable ..,.

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 veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing s ituations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and helps you to get the vehicle
back under control by select ively brak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
m 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
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 193
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations 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 conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing the vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. 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.
ESC includes and/or works together with the
anti-lock brake system (ABS), brake ass ist sys­
tem, ant i-slip regu lation (ASR), electron ic dif­
ferential lock (EDL), dynam ic steer ing* and
El ectronic interax le differentia l lock* /selective
whee l to rque control*. ESC is switched on a ll
the time. In ce rtain sit uat io ns when yo u need
less traction, you can sw itch off ASR by press­
ing the b utton
[fil ¢ page 195, fig. 178. Be
s u re to switch ASR on again when you no lon­
ger need less traction .
Anti-lock braking system (ABS )
ABS prevents the whee ls from locki ng up
when b raking. The vehicle can st ill be stee red
even during hard braking . App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake a ssis t sy ste m
The brake ass ist system can decrease braking
distance . It increases braking power when the
driver presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the situation is over. In .,,.

Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 215
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
Q) Note
Damage or malfunction due to poor fue l
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2. The ULS D No. 2 meets the ASTM D975.
D iesel fuel w ith concentrations of biodiese l
highe r than 5 % such as Bll, B2O or BlOO are
strictly prohib ited.
Serv ice stat ion fuel pumps are labeled with
the correct fuel informat ion for easy recogn i­
t ion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries.
ULSD No. 2 can become thicker in very cold
temperatures, and this can impair the en­ gine's start ing and running. Depending on the
season, gas stat ions provide ULSD No. 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usua l.
(D Note
-Your vehicle's diesel engine was de­
signed soley for use with ULSD No. 2.
Th erefore, never use gasoline, heating
oil, other f uels or flow improvers . These
contain substances that wi ll severely
damage the fuel system and the engine. .,.

Using the proper engine oil is important for
the functionality and service life of the en­
gine. Your engine was factory -filled with a
high-quality oil which can usually be used
t h roughout the entire year.
Your Limited New Vehicle Warranty does not cover damage or malfunctions due to
failure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet .
- Use only a high quality engine oil that ex­
pressly complies with the Audi oil quality
standard specified for your vehicle's en­
gine . Using any other oil can cause seri­
ous engine damage.
- Do not mix any lubricants or other addi­
tives into the engine oil. Doing so can
cause engine damage.
If you need to add oil and there is none
available that meets the Audi oil quality
standard your engine requires, you may
add a total of no more than 0.5 quart/liter
of a high-quality "synthetic"oil that meets
the following specifications.
- Vehicles with gasoline engine: ACEA A3
or API SM with a viscosity grade of
SAE 0W-30, SAE SW-30 or SA E SW-40.
- Vehicles with diesel engine: ACEA C3 or
API CF with a viscosity grade of
SAE 0W-30 or SAE SW-30.
- For more information about engine oil
that has been approved for your vehicle, please contact either your authori zed

Checking and filling 225
Engine oil consumption
T he 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 effec tive lubrication and
cooling of internal engine components, all in ­
ternal combustion engines consume a certain
amount of oil. Oil consumption varies from engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see
c::> page 200) consume more oil during the
break-in period than they consume after oil
consumption has stabili zed.
Under normal 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 condi tions. Further fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With all these variables coming into play, no
standard rate of oil consumption can be es ­
tablished or specified . There is no alternative
to regular and frequent checking of the oil lev­
el , see
Note.
If the yellow engine oil level warning symbol
in the instrument cluster
II lights up, you
should check the oil level as soon as possible
c::> page 226. Top off the oil at your earliest
convenience
c::> page 226.

.. Read the brake fluid level from the brake
fl uid reservoir¢
fig. 192, ¢ page 224,
fig. 188 .
The brake f luid level must be be­
tween the "MIN" and "MAX" markings .
The location of the brake flu id reservo ir can be
seen in the engine compa rtment illust rat ion
¢ page 224.
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake wa rning/indi­
cator ligh t. (U .S. models) . (Canad ian
models) will come on ¢

Changing brake fluid
Have the brake fluid changed by an experi·
enced technician .
Brake fluid absorbs mois ture from the air. If
the wa ter content in the brake fluid is too
high , corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also dec rease considerably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
ev ery two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "F MVSS 116 DOT 4".
The brake fluid reservo ir can be d iff icult to
reach, the refore, we recommend that you
have the brake fluid changed by your author­
i zed
Audi d ealer . Your dealer has t he correct
tools, the right brake fl uid and t he know-how
to do this for you .
A WARNING
-.
-Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f luid. Observe these pre­
cautions:
- Use only brake fluid that meets SAE
spe cificat ion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 116.
Always check with yo ur authorized Audi
dealer to make sure yo u are using the
correct bra ke fluid. The correct type of
brake f luid is also indicated on the
brake f luid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong . This can seriously affect the effi ­
c iency of the brakes as well as your
safety. Th is cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

232 Checking and filling
@ For the sake of the environment
Because of the problem of proper disposal
of brake fluid as we ll as the special tools
required and the necessary expertise, we recommend that you have the brake fluid
changed by your author ized Audi dealer.
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte­
nance. With
high outside temperatures or
long daily drives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level should also be
checked each time the battery is charged
¢ page 234.
Have the battery checked when you take your
vehicle in for service . You are well adv ised to
replace a battery that is older than 5 years .
With certain types of airbag deployment, the battery is disconnected from the vehicle elec­
tr ical system for safety reasons¢
& in Re­
pair, care and disposal of the airbags on
page 161.
Disconnecting the battery terminals
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are disconnected. These functions have
to be relearned after the battery terminals are
connected again. To prevent this , the battery
should only be disconnected from the vehicle
e lectrica l system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capabi lity over a longer period
¢page 198. Some of the convenience func­
tions may not operate, such as the interior
lights or power seat adjustment. The conven- ience
functions will be available again when
you switch on the ignition and start the en­ gine.
Winter operation
During the winter months, battery capac ity
tends to decrease as temperatures drop. This
is because more power is a lso consumed whi le
starting, and the headlights, rear window de­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticu larly in city traffic or when traveling only
short distances. Let your authorized Audi
deale r check the capacity of the vehicle bat ­
tery before winter sets in¢
page 234 . A well
charged battery will no t only prevent star ting
problems when the weather is cold, but will
also last longer .
@ Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery shou ld be removed and
stored where it w ill not freeze. This will
prevent it from be ing damaged and having
to be replaced .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check any­
thing in the luggage compartment,
read and
heed all WARNINGS
¢ .&, .
Always heed the safety warnings , when work­
ing on the vehicle battery or the vehicle elec­
t rical system to prevent injury.
The following WARNINGS are very
important when working on the battery:
Always heed the following WARNING SYM-
BOLS and safety precautions when working
on the battery.
