-Improper reliance on the side assist system
can cause collisions and serious personal in­
jury:
- Never rely only on side assist when chang­
ing lanes .
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Sid e assist cannot detect a ll vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your
blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not
function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- in poor weather conditions such as heavy
rain, snow or heavy m ist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface . Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody. This can affect the system . Have
your authorized Audi dealer or authorized
Audi Service Facility check their function.
(D Tips
-If the window g lass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be misin­
terpreted.

Safety bel ts
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 tensioners
The safety belts on the front seats are eq uipped
with power reversib le tensioners. The fo llow ing
funct ions are availab le when the driver's/front
passenge r's safety belts are fastened:
- Automatic tens ioners : at the start of a drive,
the safety belts automat ica lly adjust to the
passenger after a certain time per iod or vehicle
speed. To sw itch the automat ic tensioners off,
s e lect the following in the MMI:
!CA RI fu nction
button
> (Car )* systems > Vehicle s etting s >
Seats > Driver's seat or Pass enger' s seat > Au­

- In ce rtai n dr iv ing s ituations, the safety belts
may tighten w ith a revers ible tens ion ing f unc­
t ion

-The s afety be lt s may also t igh ten wi th th is re-
versible tens ion ing funct ion in m inor collisions.
Pyrotechnic safety belt pretensioners
The safety belts are equ ipped with safe ty belt
pretensioners . The system is act ivated by se nsors
i n front, side and rea r-e nd coll is ions of great se­
ver ity and in a ro llover. This tig htens the belt and
ta kes up belt slack¢ .&.

movement during a collision.
A WARNING
- It is poss ible for the pretens ioners to deploy
incorrectly.
- The pyrotechnic system can only provide protection for one coll is ion. If the pyrotech­
n ic pretensioners deploy, the pretens ion ing
sys tem must be replaced .
(1) Tips
The pyrotechnic safety be lt pretensioners can
o nl y dep loy once . .,.
141

Safe ty belt s
- The safety belt pretensioners do not deploy
in minor frontal and side collisions, in rear­
end collisions, in rollovers and in collis ions
invo lv ing very little impact force.
- A fine dust is released when the pyrotechnic
safety be lt pretensioners dep loy. This is nor­
mal and is not caused by a fire in the vehi­
cle.
- The relevant safety requirements must be observed when the vehicle 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 othe r regulations if the vehicle or indi­
v idual parts of the system, particularly the
safety be lt or a irbag, are to be disposed. We
r ecommend you have your autho rized Aud i
dealer perform this service for you .
Service and disposal of safety belt preten­
sioner
The safety be lt pretensioners are parts of the
safety belts on your Audi . Installing, removing ,
servicing or repa iring of belt pretens ioners can
damage the safety belt system and prevent it
from working correctly in a co llision.
There are some important things you have to know to make sure that the effect iveness of the
system w ill not be impaired and that d isca rded
components do not cause injury or pollute the
env ironment.
_& WARNING
-
Imprope r care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing a safety belt preten­
sioner from activating w hen needed or acti­
vating it unexpectedly :
- The be lt pretensioner system can be activat­
ed only once .
If belt pretensioners have
been act ivated, the system must be re­
placed .
- Never repa ir, adjust, or change any parts of
the safety be lt system .
142
-Safety belt systems including safety belt
pretens ioners cannot be repa ired. Spec ial
procedures are required for remova l, instal­
lation and disposal of this system.
- For any work on the safety belt system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified technician
who has an Audi approved repair manual, train ing and spec ial equ ipment necessary .
@ For the sake of the environment
Undeployed airbag modules and pretension­
e rs might be classified as Perchlorate Material

r ate. When the vehicle or pa rts of the re­
straint system incl uding airbag modules safe­
ty belts w ith pretens ioners are scrapped, all
applicable laws and regulations must be ob­
served . Your a uthorized Audi dealer is familiar
with these requirements and we recommend
that you have your dea ler perform this serv ice

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
performs in a crash. For example, using tire-rim
comb inat ions not approved by Audi, lowering the
vehicle, changing the stiffness of the su spension,
including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic control un it. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made . Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
ing when it should.
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in ­
crease the risk of ser ious personal injury in a
crash.
- Never install suspens ion components that
do not have the same performance charac­
teristics as the components originally instal­
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.
Airbag system
Knee airbags
Description of knee a irbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants .
Fig. 161 D river 's knee a irbag
T he driver knee airbag is in the instrument panel
underneath the steering wheel
¢fig.161, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front airbags dep loy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met
¢ page 152 , More important things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection .
The airbag system is not a substitute for your
safety belt . Rather, it is part of the overall occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is why you should a l­
ways wear your safety belt, not just because the
law requires you to do so¢

Intelligent Technology Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re­
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa­
tions, such as an a irbag deployment or hitting a
road obstacle, data that will assist in understand­
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy­
namics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
- How various systems in your vehicle were oper­
ating;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can he lp 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 requ ired, and access to the vehicle or the
E DR 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 retr ieval or down­
l oading of data stored by EDRs installed in a vehi­
cle for the express purpose of retrieving data af-
Intelligent Technology
ter an accident or crash event without the own­
er's consent.
A udi will not access the EDR and/or similar data
o r 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
veh icle operation and safety performance or
provide the data to a third party for research
purposes without identifying the specific vehi­
cle or information about the ident ity 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
electron ic control modules for various vehicle
systems, such as eng ine management, emission
control, airbags, and safety belts.
These electronic control modules record data during norma l vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capabil ity of these
modules is lim ited to data (no sound is reco rded).
Only a small amount of data is actua lly recorded
over a very limited period of time, or stored when
a system fau lt is detected by a contro l module.
Some of the data stored may relate to vehicle
speed, direction, or braking, as well as restraint
system use and performance in the event of a
crash . Stored data can also only be read and
downloaded w ith specia l equipment that is di­
rectly connected to the vehicle.
(D Tips
Your vehicle may be equipped with Audi con­
nect. Your use of certain Audi connect fea­
tures requires wireless services that are pro­
v id ed by a third party wire less telecommuni­
cations provider . For detai ls regard ing how in­
formation obtained through Audi connect is
