Intelligent Technology
-How fast the vehicle was traveling.
These data can help provide a better understand­ ing of the circumstances in which crashes and in­
juries occur. NOTE : EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs ;
no data are recorded by the EDR under normal
driving conditions and no personal data (e.g.,
name, gender, age, and crash location) are re­
corded. However, other parties, such as law en­
forcement, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
To read data recorded by an EDR, special equip­ ment is required, and access to the vehicle or the
EDR is needed . In addition to the vehicle manu­
facturer, other parties, such as law enforcement,
that have the special equipment, can read the in­
formation if they have access to the vehicle or the
EDR.
Some state laws restrict the retrieval or down­
loading of data stored by ED Rs installed in a vehi­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own­
er's consent.
Audi will not access the EDR and/or similar data
or give it to others -
- unless the vehicle owner (or lessee if the vehi­
cle has been leased) agrees; or
- upon the official request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the judicial
discovery process.
- Audi may also use the data for research about
vehicle opera tion and safety performance or
provide the data to a third party for research
purposes without identifying the specific vehi­
cle or information about the identity of its own­
er or lessee and only after the recorded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emission
control , airbags, and safety belts.
128
These electronic control modules record data
during normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capability of these
modules is limited to data (no sound is record­
ed) . Only a small amount of data is actually re­
corded over a very limited period of time, or stor­
ed when a system fault is detected by a control
module . Some of the data stored may relate to
vehicle speed , direction , or braking, as well as re­
straint system use and performance in the event
of a crash. Stored data can also only be read and
downloaded with special equipment that is di­
rectly connected to the vehicle.
@ Tips
Your vehicle may be equipped with Audi con­
nect. Your use of certain Audi connect fea­
tures requires wireless services that are pro­
vided by a third party wireless telecommuni­
cations provider. For details regarding how in­
formation obtained through Audi connect is
collected, processed, transmitted, used, and
shared, please see your contract with the
wireless telecommunications provider and the

Audi pre sense
Preventative passenger
protection
A pp lies to: ve hicles w ith Audi p re se nse
Pre sense can initiate steps to protect vehicle oc­
cupants in certain dangerous situations. The
functions described are available depending on
veh icle equipment:
Pre sense basic*
The following functions can be triggered in cer­
tain driving situations:
- Tensioning of the safety belts (for example,
during heavy braking): the front safety belts
have reversible belt tensioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger again.
- Closing the windows and the sunroof* (for ex­
ample, when
over-or understeering): the win­
dows and the sunroof* close until there is only
a small gap open.
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or higher.
Drive select: the deployment time is adapted in
Dynamic mode.
Pre sense front (vehicles with adaptive cruise
control*}
Pre sense front contains the functions of pre
sense basic . In addition, the likelihood of a rear­
end collision with the vehicle ahead is also calcu­
lated, within the limits of the system. If the risk
of a collision is detected, the following functions
can trigger:
- Braking guard
c:> page 94
- Tensioning of the safety belts
- Closing the windows and the sunroof*
Pre sense rear (vehicles with side assist*)
Pre sense rear contains the functions of pre sense
bas ic. In addition, the likelihood of a rear-end
coll ision from the vehicle beh ind is also calculat­
ed, within the limits of the system. If the risk of a
collision is detected, the following functions can
trigger:
138
- Tensioning of the safety belts
- Closing the windows and the sunroof*
Pre sense plus*
Pre sense plus contains the functions of pre
sense front and pre sense rear .
Error message
Audi pre sense: Unavailable
Preventative passenger protection is not availa­
ble. Drive to your authorized Audi dealer or au­
thorized Audi Service Facility immediately to have
the malfunction corrected.
A WARNING
Pre sense cannot overcome natural physical
laws. It is a system designed to assist and it
cannot prevent a collision . Do not let the in­
creased safety provided tempt you into taking
risks. This could increase your risk of a colli­
sion.
- The system can deploy incorrectly .
- Please note that the sensors do not always
detect all objects . This increases the risk of
a collision .
- Pre sense does not react to people or ani­
mals or objects that are crossing the vehi­
cle 's path or are difficult to detect
c:> page 89.
- Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collision risk.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense can be impaired by this.
Have an authorized Aud i dealer or authorized
Audi Service Facility check their function.
{!) Tips
-Certain pre sense front functions switch off
when sport mode is switched off or when
driving in reverse. ..,.

Improperly worn safety belts
Incorrectly positioned safety belts can cause se­
vere injuries.
Wearing safety belts imprope rly can cause seri­
ous injury or death. Safety belts can only work
when they a re correctly pos itioned on the body.
Imp roper seating positions reduce the effect ive­
ness of safety be lts and will even inc rease the
ris k of injury a nd deat h by mov ing the safety bel t
to cr it ica l areas of the bo dy. Imp roper seating
positions a lso increase the risk of serio us inj ury

Belt tensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity and in a rollover, safety belts are tensioned automatically.
Reversible safety belt tensioner s
The safety belts on the front seats are equipped
with power revers ible tensioners. The following
funct io ns are available when the dr iver's/front
passenger 's safety belts are faste ned:
- Automatic tensione rs: at the start of a drive,
the safety belts automat ica lly adjust to the
passenger after a certain time period or ve hicle
spee d. To switch the a utomat ic tens ioners off,
select the following in t he M MI :

vers ible tension ing f unct io n in m ino r collisions .
Pyrotechnic safety belt pretensioners
The safety belts are eq uipped w it h safety bel t
pretensione rs. The system is activa ted by se nsors
i n front, s ide a nd r ear-end collisions of grea t se ­
verity and in a ro llover. This tig htens the bel t and
takes up belt slack
c> &. in Service and disposal of
safety belt pretensioner on page 147.
Taking up
the slack helps to reduce forward occupant
movement during a collision.
A WARNING
-It is poss ible for the pretensioners to dep loy
incorrectly .
- The pyrotechnic system can only p rovide
protection for one collision. If the py rotech­
nic pretens ioners deploy, the pretensioning
sys tem must be rep laced.

\.J ' @ Tips
The pyrotechnic safety belt pretensioners can
only deploy once.
- The safety belt pretensioners do not dep loy
in minor fronta l, side and rear-end co lli­
sions.
- A fine dust is released when the pyrotechnic
safety be lt pretensioners deploy . This is nor­
mal and is not caused by a fire in the vehi­
cle.
- The relevant safety requirements must be
observed when the veh icle or components
of the system are scrapped. A qualified
dealersh ip is familiar with these regulations
and will be p leased to pass on the informa­
tion to you.
- Be sure to observe all safety, environmental
and other regulations if the veh icle or indi­
v idual parts of the system, particularly the
safety be lt o r airbag, are to be disposed. We
recommend yo u have your author ized Audi
dealer perform this serv ice for you.
Service and disposal of safety belt preten­
sioner
The safety belt pretens ioners are parts of the
safety belts on your Audi. Installing, removing,
servicing or repa iring of belt pretensioners can
damage the safety belt system and prevent it
from wor king cor rectly in a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment.
& WARNING
Improper care, servicing and repa ir proce­
dures can increase the risk of personal injury
and death by preventing a safety be lt preten­
sioner from activating when needed or acti­
vating it unexpectedly :
- The be lt pretensioner system can be act ivat­
ed only once. If belt pretensioners have
been activated, the system must be re­
placed.
S afet y be lts
- Never repair, adjust, or change any parts of
the safety belt system .
- Safety belt systems including safety belt
pretensioners cannot be repaired. Special
procedures are required for removal, instal­
lation and disposal of this system.
- For any work on the safety belt system, we
strong ly recommend that you see your au­
thor ized Audi dealer or qualified techn ician
who has an Audi approved repa ir manual,
tra ining and special equipment necessary .

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For e xamp le, using t ire -r im
comb inations no t approved by Audi, lowering t he
veh icle, chang ing the stiffness o f the suspe nsio n,
i n cluding the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic contro l unit . Some suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in c rashes in w hich it would not deploy if
the changes had not been made. Other ki nds of
164
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in­
crease the r isk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac­
ter istics as the components origina lly instal­
led on your vehicle.
- Never use tire-r im combinations that have
not been approved by Aud i.
Knee airbags
Description of knee airbags
Applies to : vehicles with knee airbags

0 Note
-Me thanol f uels which do no t meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system .
- Do not use fuels that fail to meet the spec i­
fied criteria in this chapter .
- If you are unable to determine whether or not a particular fuel blend meets the spec i­
fications, ask your service station or its fuel supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jo r concern among many auto manufactur­
ers is carbon deposit build- up ca used by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . All gaso line grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIE R Detergent Gas­
oline. For more information on TOP TIER Deter ­
gent Gasoline, please go to the official website (www.toptiergas .com) .
192
After an extended period o f using inadequate
fuels, carbon deposit bui ld-ups can rob your en­
gine of peak performance.
([) Note
Damage or ma lf u nction due to poor fue l qual ­
ity is not covered by the Audi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles wi th diese l en gin e
Always use ULSD (Ultra Low Sulfur Diese l) No. 2 .
The ULSD No. 2 meets the ASTM D97S.
D iesel fuel w ith concentrations of b iod iesel high­
er than 5 % such as B l 1, B20 or BlOO are st rict ly
prohibited .
Se rvice station fuel pumps are labe led wi th the
correc t fu el i nfo rmation for easy recogn ition by
the user . If the diesel fue l pump is not labe led
ask the station operator what fue l is being dis­
pensed before filling up your vehicle .
U LSD No . 2 may no t be ava ilable outside the USA
and Canada . Be s ure to check befo re t raveling to
other countries .
U LSD No . 2 can become th ic k e r i n very co ld tem­
peratures, and this can impa ir the e ng ine's s tart­
i ng and running . Depend ing on the season, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
(D Note
- Your vehicle's diese l engine was designed
so ley for use with ULSD No . 2 . Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system and the engine. Such damage will not be
covered by your New Vehicle Limited War­
ranty.
- If you put any amo unt of incorrect fuel in
the fuel tank, do not start the engine under
any c ircumstances. Immed iate ly contact the

\.J ' -Do not drive until the fuel tank becomes
complete ly empty . The engine cou ld mis­
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requ ir­
i ng its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and

book let.
- Lack of proper maintenance as we ll as im ­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
® For the sake of the environment
Even when the Emission Control System is op ­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states. This depends on the su lfur
content of the fuel being used. Using a differ­
ent brand of fue l may help, or filling the tank

Diesel particulate filter
Applies to: veh icles with diesel engine
The diesel particulate filter filters nearly all of
the soot particles out of the exhaust. The filter
cleans itself automatically under normal driving
conditions . If the filter cannot clean itself (for ex­
ample , because you are only driving short distan­
ces), the fi lter becomes clogged with soot and

- Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Engine compartment
Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment, such as
checking and filling fluids, there is a risk of in­
jury, scalding, accidents, and burns. For this
reason, follow all the warnings and general
safety precaution s provided in the following in·
formation . The engine compartment is a dan­
gerous area on the vehicle.
¢ ,&..
A WARNING
= =--
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
-Select the P selector lever position.
- Let the engine cool down.
- Never open the hood when there is steam or
coolant escaping from the engine compart­
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping .
- Keep children away from the engine com­
partment .
- Never sp ill fluids on a hot engine. These flu­
ids (such as the freeze protection contained
in the coolant) can catch fire.
- Avoid short circuits in the electrical system.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
coo ling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
199

Checking and Filling
-Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If tests need to be performed with the en­
gine running, there is additional danger due
to moving components (such as the ribbed belt, alternator and radiator fan) and from
the high voltage ignition system.
- Do not under any circumstances give gas in­
advertently (for example, by hand from the
engine compartment) if the vehicle is sta­
tionary but the engine is running and a gear
is engaged. Otherwise, the vehicle will start
to move immediately and this could result
in an accident.
