Sensors in the bumper
Sensors are located in the rear bumpers . If these detect a n obsta cle,
audib le and visual sig nals wa rn you. The range at w hich the sensors
beg in to measure is approximately:
T o the sid e
2 ft (0. 60 m)
Center rear 5 .2 ft (1.60 m)
Distan ce warning when reversing s tarts w hen an obsta cle is detec ted
in the range of the parking ass ist system. As the d ista nce decreases,
t he time in te rval between the audib le tones becomes shorter .
When the dis tance is less tha n 1ft
(0.30 m), the tone becomes
cont inuo us. At th is point yo u should stop back ing up.
If the dis tance to an obs tacle stays the s am e, t he volume o f the
distance signal chime is grad ually reduced after about
4 seconds
(does not affe ct the conti nuous signal tone) . App roac hing an oth er

Switching on/off
The rear view camera switches on automatically together
with the acoustic park assist when you put the vehicle in
reverse.
Switching on
- Before parking with the rear view camera , the Adaptive Air
Suspension* comfort or automatic mode must be
switched on=:>
page 16.
-Put the vehicle in reverse gear, the acoustic parking
system with rear view camera is activated automatically .
Activation of the acoustic parking system is confirmed by
a brief acknowledgement sound.
Switching off
- Drive faster than 6 mph (10 km/h), or
- take the vehicle out of reverse gear. The acoustic parking
system is immediately deactivated, and the rear view
camera picture is deactivated automatically after a period
of about 15 seconds, or
- switch off the ignition.
The delay in deactivating the camera provides an uninterrupted view
behind the vehicle especially when maneuvering in tight parking
spaces and prevents the picture from turning off the every time you
shift out of reverse . If the warning message appears in the display but
not the rear view
camera picture, read and confirm the warning message. The acoustic
distance signal is always active.
If you press a function button on the MMI control console, the rear
view camera picture disappears. The rear view camera picture reap­
pears the next time you park.
Further information on the warning message and the MMI control
console can be found in the MMI instruction booklet .
(I] Tips
• The rear view camera picture is available as soon as the MMI
Display or the M Ml is switched on, or the start-up phase is completed.
• Keep the sensors in the rear bumper and the rear view camera lens
clean and free of snow and ice, so that the parking system can work
properly . Please follow the additional notes on~

[I) Tips
• T he shoulder belt part shou ld route approximate ly over the
middle of your shoulder -under no circumstances should it route over
you r neck a nd throat area~
& in "Safety belt position" on page 192.
• With the front seats, the height adjustment of the seat can also
be used to adjust the position of the safety belts. •
Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
nes.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly
positioned on the body . Improper seating positions reduce
the effectiveness of safety belts and will even increase the
ris k of injury and death by moving the safety belt to critical
areas of the body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and str ikes an occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all vehicle occu­
pants and especially for children. Therefore:
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while traveling
~ & .
& WARNING
Impr ope rly w orn safet y belts inc re a se the ris k of se rious pe rsonal
injury and de ath whenever a vehi cle i s be ing u sed .
• Alway s mak e sure th at all vehicle occupants are corre ctl y

Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear -end collisions above a particular
severity, safety belts are tensioned automatically.
Th e safety belts are equipped with safety belt p retensioners. The
system is activated by sensors in front, side and rear-end collisions of
great sever ity. This tightens th e be lt and ta kes up belt slack~
& in
"Service and disposal of safety belt pretens ioner". Taking up the slack
helps to reduce forward occ upan t movement during a coll is io n.
0 Note
Never let the bel t remain over a rear seat back that has been folded
forward.
[I) Tips
The safety belt pretensioner can only be act ivated once.
• In minor fronta l, side and rear -end collis ions, in a rollove r and in
acc idents involving very little impact force, the safety belt preten­
sioner are not activated .
• When the safety belt pretensioners are activated, a fine dust is
re leased. This is norma l and is not ca used by a fire in the vehicle.
• The relevant safety requirements must be observed when the
vehicle o r components of the system a re scrapped. A q ual ified deal­
ersh ip is familiar with these regulat ions and will be pleased to pass on
the information to you .

If, in exceptional circumstances, you must in stall a forward-facing
child restraint on the front passenger 's seat:
• Always make sure the forward-facing seat has been d esigned
and certified b y its manufacturer for use on a front seat with a
pas senger front and side airbag.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmo st position in
the seat 's fore and aft adjustment range, as far away from the
airbag as possible , before in stalling the forward-facing child
restraint. The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on

Advanced Airbag System components
The front passenger seat in your veh icle has a lot of very important
parts o f the A dvanced A irbag System in it. These p arts incl ude t he
we ight-sens ing mat, sensors, wiring, brackets, and more. The func­
t ion o f the sys tem in t he front passenger sea t is che cked by the elec ­
tron ic contro l unit when the ignit ion is on . The contro l unit mo nitors
t he Advanced Air bag System and t urns the airbag indica tor ligh t on
when a malfunction in t he system compone nts is detected. The func­
tion of the a irbag indicator light is descr ibed in greater detail be low. Because the front passenger seat co
nta ins important parts of t he
Adv anced Ai rbag System, you mus t tak e ca re to p reve nt i t from be ing
damaged . Damage to the seat may p revent the Advanced A irbag for
the front passenge r seat from do ing its job in a crash .
The front Advanced Airbag System consists of the
following:
• Cras h sensors in the front of the ve hicle tha t meas ure vehicle
acc elera tion/de ce le ra tion to prov ide info rm ation to the Advanced
Airbag System about the severity of the crash .
• An e lec tron ic contro l unit, w it h i ntegr ate d crash sensors fo r front
and side i mpacts . The control unit "dec ides" w het her to fire the front
airbags based o n the information rece ived from the c rash sensors .
T he contro l unit also "decides" whether the safety be lt prete nsioners
should be activated.
• An Advanced Airbag with gas generator fo r the driver inside the
s teer in g wheel hub.
• An Advanced Airbag with gas generator inside the instrument
p ane l for the front p assenge r.
• A weight-sensi ng mat under the upho lstery padd ing of the front
passenge r seat cushion that measu res the tota l we ight on the se at.
The informat ion registered is sent continuously to the electronic

& WARNING
Damage to the front passenger seat can prevent the front airbag
from working properly.
• Imprope r repair or disassembly of the front passenger and
driver seat will prevent the Advan ced Airbag System from func­
tioning properly.
• Repairs to the front passenger seat must be performed by qual­
ified and properly trained workshop personnel.
• Never remove the front passenger or driver seat from the
vehicle.
• Never remove the upholstery from the front passenger seat.
• Never disassemble or remove parts from the seat or disconnect
wires from it .
• Never carry sharp objects
in your pockets or place them on the
seat. If the weight-sensing mat in the passenger seat is punctured
it cannot work properly .
• Never carry th ings on your lap or carry objects on the passenger
seat . Such items can increase the weight regi stered by the weight­
sensing mat and send the wrong information to the airbag control
unit.
• Never store items under the front passenger seat. Parts of the
Advanced Airbag System under the passenger seat could be damaged, preventing them and the airbag system from working
properly.
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats.
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraint s or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly .
Controls and equip­
ment Safety first Vehicle operation
& WARNING
(co ntinued )
• Never use cushions , pillows, blankets or similar items on the
front passenger seat . The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
c hild restraint or person on the seat and prevent the Advanced
Airbag System from functioning prope rly.
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require the use
of a towel, foam cushion or something else to properly pos ition
the child restraint, make certain that the PASSENGER AIR BAG
OFF light come s on and stays on whenever the child re straint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install child restraint in a rear seating posi­
tion and have the airbag system inspe cted by your Audi dealer. •
How the Advanced Airbag System
components work together
Th e fron t Advanced A irbag System and t he side airbags sup plemen t
the protect ion offered by the front three-po int safety belts with
prete nsioners and load limiters a nd t he adjusta ble head restra ints to
help reduce the risk of i njur y in a w ide range of acc ident and crash
situ ati ons. Be sure to re ad the important info rmat io n a bou t safe ty
and heed the WAR NINGS in this chapte r.
Deployment of the Adv a need Airbag System and the a ct iva tion of t he
sa fety belt pretens ioners depend on the dece leration measured by
the c rash sensors and reg istered by the e lectron ic contro l un it. Crash
sever ity depe nds on speed and deceleration as well as the mass and
st iffness of t he ve hicle or object invo lved in the crash.
Whe n the ele ct ronic con tro l u nit r egi sters a low sever ity crash and
the safety be lt is being used, the airbag will not dep loy . If the safety
bel t is not being used, the fi rs t st age de ploys, followed by the second
stage after a much later time in the crash seq uence. IJ,,

& WARNING (conti nued)
• Never recline the front passenger's seat to transport objects.
Items can also move into the area of the s ide airbag or the front
airbag during braking or in a sudden maneu ver. Objects near the
airbags can become projectiles and cause injury, particularly when
the seat is reclined .
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other br eathing
conditions.
• To reduce the risk of breathing problems, those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the veh icle or opening windows or doors.
• If you are in a colli sion in which airbags deploy, wa sh your
hands and face with mild soap and water before eating .
• Be careful not to get the dust into your eyes, or into any cuts or
scratches.
• If the residue should get into your eyes, flush them with
water .•

Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
t h e Advan ced Airbag System pe rforms in a cr ash . For e xamp le, usi ng
tire-rim combinations not app roved by Audi, lowering the vehicle,
c hang ing the stiffness o f th e suspension, incl uding the sp rings,
suspension struts, shock absorbers etc. can change the forces that
are meas ured by the a irbag sensors and sent to the ele ct ronic contro l
unit . Some suspension changes can, fo r exam ple, increase the force
levels measured by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had no t been
ma de . Other kinds of changes may reduce the force levels meas ured
by the sensors and p revent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front
p as senge r se at tell the e lectroni c cont rol mo dule if the sa fe ty belt is
latched or not . If the safety belt is being used, t he front a irbag w ill
dep loy a t a s lightly h igher r ate o f vehicle decele ration t han if t he
safety belt is not be ing used . Therefo re, in a par ticular collis io n, it is
possible that an a irba g w ill not dep loy at a seating position where the
safety belt is being used but w ill inflate at the posit ion where the
safety belt is not be ing use d. It is im portant that nothing interfere
w it h t he safety belt bu ckles so that t he sensors can se nd the co rrect
info rmation about safety be lt use to the electronic contro l unit.
