Fig . 17 1 Tru nk l id:
L oca tion of th e r ear
vi ew c amera
Sensors are located in the rear bumpers. If these detect an obstac le,
audible and visual signals warn you . The range at which the sensors
begin to measure is approximately:
To the side 2 ft (0.60 ml
Center rear
5.2 ft (1.60 m)
Distance warning when reversing starts when an obstacle is
detected in the range of the parking assist system. As the distance
decreases, the time interval between the audible tones becomes
shorter.
When the distance is less than 1ft (0.30 ml, the tone becomes continuous . At this point you should stop backing up.
If the distance to an obstacle stays the same, the vo lume of the
distance signal chime is gradually reduced after about 4 seconds
(does not affect the continuous signal tone). Approaching another
obstac le wi ll cause the distance signal to sound again at the normal
volume.
R ea r vi ew camera cover age ar ea
The MMI display shows the area covered by the rear view camera
=>
page 157, fig . 170 G) . Objects that are not in the area covered 0
are not shown on the MMI display. We recommend that you practice parking with the rear view camera
in a traffic -free location or parking lot to become familiar with the
system, the orientation lines, and their function. When doing this,
there should be good ligh t and weather conditions.
In the MMI d isplay, objec ts or vehicles appear closer or further away
if:
• you are driving in reverse gear from a level surface onto an
incline, or a downward slope,
• you are driving in reverse gear toward protruding objects,
• the vehic le is carrying too much load in the rear.
The accuracy of the orientation lines and b lue surfaces diminishes
if:
• the rear view camera does not provide a reliable image, for
example, in poor visibility conditions or if the lens is dirty,
• the image on the screen is not visible due to sun glare and reflec ­
tion.
C aring for the rear vi ew c amera l en s
The rear view camera is located above the rear license plate bracket.
For the parking assist to operate, the lens => fig. 171 must be kept
clean :
• Dampen the lens with a household alcohol -based glass cleaner,
and clean the lens with a dry cloth
~ 0 .
• Remove snow with a hand brush and ice preferably with a de ­
icing spray=>

take t he vehicle out of reve rse gear . The acoustic parking
system is immediate ly deactivated, and t he rear view
camera picture is d eactivated automatica lly after a
period of about 15 seco nds, 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.

Unfastening safety belts
Unbuckle the safety belt with the red release button only
after the vehicle has stopped.
Fig . 193 Releasing the
tongue from the buckle
-Push the red release button on the buckle~ fig. 193. The
belt tongue will spring out of the buckle~&_ .
- Let the belt wind up on the retractor as you guide the belt
tongue to its stowed position.
& WARNING
Never unfasten safety belt while the vehicle is moving. Doing so
will increase your risk of being injured or killed. •
Improper ly worn safetY belts
Incorrectly positioned safety belts can cause severe inju­
nes.
Wearing safety be lts 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 risk of injury and death by moving the safety belt to critical areas
of the body. Improper seat ing positions also increase
the risk of serious injury and death when an airbag deploys and strikes an occupant who is not in the correct seating
position. A driver is responsible for the safety of all vehicle
occupants and especially for children. Therefore:
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while traveling
~ &_.
& WARNING
Improperly worn safety belts increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants are correctly
restrained and stay in a correct seating position whenever the
vehicle is being used.
• Always read and heed all WARNINGS and other important infor­
mation
~ page 182. •
Safety belt pretensioners
How safety belt pretensianers work
In front, side and rear-end collisions above a particular
severity, safety belts are tensioned automatically.
The safety belts are equipped with safety belt pretensioners. The
system is activated by sensors in front, side and rear-end collisions
of great severity. This tightens the belt and takes up belt slack~,&
in "Service and disposal of safety belt pretensioner " on
page 187 .
Taking up the slack helps to reduce forward occupant movement
during a collision. .,

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced A irbag System in it. These parts inc lude the
weight -sensing mat, sensors, wiring, brackets, and more. The func -
Controls and equip­ ment Safety first Vehicle operation tion of the system in the front passenger seat is checked by
the elec­
tronic contro l unit when the ignition is on . The control unit monitors
the Advanced Airbag System and turns the a irbag indicator light on
when a malfunction in the system components is detected . The
function of the airbag indicator light is described in greater detail below. Because the front passenger seat conta ins important parts
of the Advanced Airbag System, you must take care to prevent it
from being damaged. Damage to the seat may prevent the
Advanced Airbag for the front passenger seat from doing its job in
a crash.
T he front Ad van ced Airbag System consi sts of th e
following:
• Crash sensors in the front of the vehicle that measure vehicle
acce leration/deceleration to provide information to the Advanced
A irbag System about the sever ity of the crash .
• An electronic control unit, with integrated crash sensors for front
and side impac ts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash sensors . The control unit also "decides" whether the safety belt
pretensioners should be activated.
• An Advanced Airbag w ith gas generator and contro l valve for the
driver inside the steering wheel hub.
• An Advanced Airbag with gas generator and contro l valve inside
the instrument panel for the front passenger .
• A weight -sensing mat under the upholstery padding of the front
passenger seat cushion that measures the total weight on the seat .
The information registered is sent continuously to the e lectronic
control unit to regu late dep loyment of the front Advanced Airbag on
the passenger s ide.
• An airbag monito ring system and indicator light in the instru ­
ment cluster=> page
199.
• A sensor in each front sea t registers t he distance between the
respective seat and the steering wheel or instrument panel. The
information registered is sen t continuously to the electronic control
unit to regulate dep loyment of the front Advanced Airbags. ._

& WARNING
Damage to the front passenger seat can prevent the front airbag
from working properly .
• Improper repair or disassembly of the front passenger and
driver seat will prevent the Advanced Airbag Sy stem from func ­
tioning properly .
• Repairs to the front passenger seat must be performed by qual­
ified and properly tra ined workshop personnel .
• Never remove the front passenger or driver seat from the
vehi cle .
• Never remove the uphol stery 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 things on your lap or carry objects on the
passenger seat. Such items can increase the weight registered by
the weight -sensing mat and send the wrong information to the
airbag control unit .
& WARNING (continued )
• 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 work ing
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 Sy stem from
recogn izing child restraints or occupants on the front passenger
s eat and prevent the side airbag in the seat backrest from
deploying properly.
• 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
child restraint or person on the seat and prevent the Advanced
Airbag System from functioning properly .
• 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 el se to properly position
the ch ild restraint , make certa in that the PASSENGER AIR BAG OFF
light comes on and stays on whenever the child restraint is
installed on the front passenger seat .
• If the PASSENGER AIR BAG OFF light does not come on and stay
on , immediately in stall child restraint in a rear seating position
and have the airbag system inspected by your authorized Audi
dealer .•

the protection offered by the front three -point safety be lts with
pretensioners and load limiters and the adjustab le head re straints
to help reduce the risk of in jury in a w ide ran ge of acc ident and .,_

crash situations. Be sure to read the important information about
safety and heed the WARNINGS in this chapter.
Dep loyment of the Advanced Airbag System and the activation of
the safety be lt pretensioners depend on the deceleration measured
by the crash sensors and registered by the electronic control un it.
The amount of inflation of the front airbags can also be adapted to
the front seat position, depending on the distance between the respective front seat and the steering whee l or instrument panel as
registered by sensors in the seats . Crash severity depends on speed
and deceleration as well as the mass and stiffness of the vehicle or
object involved in the crash.
On the passenger s ide, regardless of safety belt use, the airbag w ill
be turned off if the weight on the passenger seat is less than the
amount programmed in the elec tronic control unit. The front airbag
on the passenger side wi ll also be turned off if one of the child
safety seats that has been certified under Federal Motor Vehicle
Safety Standard 208 has been recognized on the seat. The
PASSENGER A IR BAG OFF light comes on and stays on to tel l you

More important things to know about front
airbags
F ig . 196 I nfl at ed front
airba gs
Safety belts are important to help keep front seat occupants in the
proper seated position so tha t airbags can unfold proper ly and
provide supplementa l protection in a fronta l collision.
The fron t airbags are designed to provide addit ional p rotection for
the chest and face of the driver and the front seat passenger when:
• safety belts are worn properly,
• the seats have been positioned so that the occupant is properly
seated as far as p ossi ble from the a irbag,
• and the head restraints have been properly adjusted .
Because airbags inflate in the blink of an eye with grea t force , things
you have on your lap or have p laced on the seat cou ld become
dangerous projectiles, and be pushed into you if the airbag inflates .
When a n airbag deploys, fine d ust is released . This is norma l and is
not caused by a fire in the vehicle. This dust is made up mostly of a
powder used to lubrica te the airbags as they d eploy . It could irri tate
skin.
I t is important to remember that while the supplemental airbag
system is designed to reduce the likel ihood of serious injuries, othe r
injuries, for example swelling, bruising and minor abrasions, can
a lso happen when airbags inflate . Airbags do no t pro tect the arms •
