increasing force within the limits of the
system
l)_ This reduces the vehicle speed in the
event of a collision. At low vehicle speeds, pre
sense front can initiate a complete deceleration
shortly before a collision with a vehicle driving
ahead
1>. If pre sense front determines that you
are not braking strongly enough when a collision
is imminent, it can increase the braking force .
The following functions trigger in conjunction
with pre sense basic/rear at corresponding vehi ­
cle speeds :
- Reversible tensioning of the front safety belts.
- Closing the windows and sunroof*.
- Inflating the side bolsters* in the seat backrest
and seat surface.
Audi drive select*: the reversible belt tensioner,
the closing of the windows and sunroof* as well
as the inflating of the side bolste rs* on the seat
backrest and seat surface are not active depend­
ing on the mode selected .
Collision avoidance assist
Collision avoidance assist helps you to steer the
vehicle around an obstacle in a critical situation.
If you avoid an obstacle after the acute warning,
then the collision avoidance supports you by ap­ plying slight steering adjustment to correct your
steering wheel angle as long as you are actively
steering. Collision avoidance assist is available at
speeds between approximately 20 mph (30 km/
h) and 90 mph (150 km/h).
Turn assist
When starting to drive and up to speeds of maxi­
mum 6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning left or right (available in certain countries) . The
braking intervention causes your vehicle to stay
in its lane.
.8, WARNING
-Pre sense front cannot overcome the laws of
physics.
It is a system designed to assist and
1) This is not availa ble in some co untries.
Assist
it cannot prevent a collision in every circum­
stance. The driver must always intervene.
The driver is always responsible for braking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This could increase your risk of a collis ion.
- The system can deploy incorrectly due to
system-specific limits.
- Please note that the sensors and the camera
do not always detect all objects or lane
markings . This increases the risk of an acci­
dent.
- Pre sense front does not react to people, an­
imals or objects that are crossing the vehi­
cle 's path or that are difficult to detect
c> &..
in General information on page 97.
-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 front can be impaired
by this. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their func­
tion.
(D Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.
- Certain pre sense front functions are switch­
ed off when the ESC is limited or switched
off

Automatic safety belt r etractors
Every safety be lt is equ ipped wi th an automatic
be lt retractor on the shoulder belt. Th is feature
l ocks the belt when the belt is pull ed out fast,
during hard braking and in an accident. The belt may also lock when you drive up or down a steep
h ill or through a sharp curve. During normal driv­
ing the belt lets you move freely.
Safet y be lt pret en sioner s
The safety belts are equipped with a belt preten­
sioner that helps to tighten the safety belt and
remove slack when the pretensioner is activated
c:> page 251. The function of the pretensioner is
monitored by a warning light
c:> page 33.
Con vertible loc king retractor
Every safety belt except the one on the driver
seat is equipped with a convertible locking retrac­
tor that
mu st be used when the safety belt is
used to attach a child safety seat. Be sure to read
the impo rtant information about this feature
c:> page 288 .
A WARNING
Improperly posit ioned safety be lts ca n cause
ser ious injury in an accident

Safety belt position.
- Safety belts offer optimum protection only
when the seatback is upr ight and belts are
prope rly pos itioned on the bo dy.
- Always ma ke sure tha t the rear sea t bac k­
rest to wh ic h t he cente r rea r safety be lt is
a ttached is secure ly latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen­
ger will move forward with the backrest dur­
ing sudden braking, in a sudden maneuver
and especially in a cras h.
- Never attach the safety belt to the buckle
for another seat. Attaching the belt to the
wrong buckle w ill red uce safety belt effec­
t iveness and can cause serious personal in­
jury.
- A passenger who is not p roperly restrained
can be seriously in ju red by the safety be lt it­
self when it moves from the stronger par ts

Improperly worn safety belts
Incorrectly positioned safety belts can cause se­
vere injuries.
Wearing safety belts improperly can cause seri­
ous injury or death. Safety belts can only work
when they are correctly pos itioned on the body .
Improper seating positions reduce the effect ive­
n ess of safety be lts and will even inc rease the
ris k of injury and death by mov ing the safety bel t
to cr it ica l areas of the body. Imp roper seating
positions also increase the risk of serious inj ury
and death when an airbag deploys and strikes an
occ upant who is not in the co rrect seat ing posi­
tion. A driver is respons ible for the safety of all
vehicle occupants and espec ia lly for children.
Therefore:
.. Never permit anyone to ass ume an incorrect
s itting position in the veh icle wh ile traveling
¢ &, .
A WARNING
Improperly worn safety belts i ncrease the risk
of serious personal injury and death wheneve r
a vehicle is be ing used.
S afet y be lts
- Always make sure that all veh icle occupants
are correctly restrained and stay in a correct
seating position whenever the vehicle is be­
ing used.
- Always read and heed all WARNINGS and
other important informat ion¢

versible tens ion ing f unct ion in m inor collisions.
Pyrotechnic safety belt pretens ioners
All safety belts except for the safety belt in the
center seat position of the rea r seat are equipped
with safety belt pretensioners. The sys tem is acti­
va ted by sensors in front, side and rear-end co lli­
s ions of great severity and in a rollover. Th is
t ightens the belt and takes up belt slack¢&.
in
Service and disposal of safety belt pretensioner
on page 252.
Taking up the slack helps to re­
duce forward occupant movement during a co lli­
s io n.
(!) Tips
The pyrotechn ic safety belt pretensioners can
on ly be act ivated once.
- The safety belt pretensione rs do not deploy
in minor frontal, side and rear-end colli­
sions.
- When the pyrotechn ic safety belt preten­
sioners are activated, a fine dust is released.
Th is is normal and is not caused by a fire in
the vehicle .
- The relevant safety requirements must be
observed when the vehicle or components
of the sys tem are scrapped. An authorized

Airbag system
Important information
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job, occupants must always
properly wear their safety belts and be in a prop­
er seating position.
For your safety and the safety of your passen­
gers, before driving off, always :
.,. Adjust the driver's seat and steering wheel
properly
9 page 237,
.,. Adjust the front passenger's seat properly
¢page 238,
.,. Wear safety belts properly¢ page 247,
.,. Always properly use the proper child restraint
to protect children ¢
page 2 77.
In a collision, airbags must inflate within the
blink of an eye and with considerable force. The
supplemental airbags can cause injuries if the
driver or the front seat passenger is not seated
properly. Therefore in order to help the airbag to
do its job, it is important, both as a driver and as
a passenger to sit properly at all times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag can inflate fully and
completely and provide supplemental protection in certain frontal collisions
¢ page 237, Correct
seating position for passengers.
For details on
the operation of the seat adjustment controls
¢page 61.
It 's especially important that children are proper­
ly restrained
¢page 277 .
There is a lot that the driver and the passengers
can and must do to help the individual safety fea­
tures installed in your Audi work together as a
system.
Proper seating position is important so that the
front airbag on the driver side can do its job. If
you have a physical impairment or condition that prevents you from sitting properly on the driver
seat with the safety belt properly fastened and
Airbag system
reaching the pedals, or if you have concerns with
regard to the function or operation of the Ad­
vanced Airbag System, please contact your au­
thori zed Audi dealer or qualified workshop, or
call Audi Customer Relations at 1-800-822-2834
for possible modifications to your vehicle.
When the airbag system deploys, a gas generator
will fill the airbags, break open the padded cov­ ers, and inflate between the steering wheel and
the driver and between the instrument panel and
the front passenger. The airbags will deflate im­
mediately after deployment so that the front oc­
cupants can see through the windshield again
without interruption.
All of this takes place in the blink of an eye, so
fast that many people don't even realize that the airbags have deployed. The airbags also inflate
with a great deal of force and nothing should be
in their way when they deploy. Front airbags in
combination with properly worn safety belts slow
down and limit the occupant's forward move­
ment . Together they help to prevent the driver
and front seat passenger from hitting parts of
the inside of the vehicle while reducing the forces
acting on the occupant during the crash . In this
way they help to reduce the risk of injury to the
head and upper body in the crash. Airbags do not
protect the arms or the lower parts of the body.
Both front airbags will not inflate in all frontal
collisions . The triggering of the airbag system de­
pends on the vehicle deceleration rate caused by
the collision and registered by the electronic con­
trol unit . If this rate is below the reference value
programmed into the control unit, the airbags
will not be triggered, even though the car may be badly damaged as a result of the collision. Vehi­
cle damage, repair costs or even the lack of vehi­
cle damage is not necessarily an indication of
whether an airbag should inflate or not.
Since the circumstances will vary considerably
between one collision and another, it is not possi­
ble to define a range of vehicle speeds that will
cover every possible kind and angle of impact
that will always trigger the airbags . Important
factors include, for example, the nature (hard or
soft) of the object which the car hits, the angle of
impact, vehicle speed , etc. The front airbags will
