-Audi Parking System -------=-=---------------
-
Switch the ignition off, the entire acoustic parking
system is automatically deactivated.
The rear-view camera will deactivate automatically when you shift
into a forward gear and drive faster than about 9 mph (15 km/h) .
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.
The vehicle -obstacle distance at which the sensors start to measure
is
about:
To the side 2 ft (0.60 m)
Center rear 5.2 ft (1.60 ml
Backing up
Distance notification when backing up starts when an obstacle is
detected that is within range of the Audi Parking System. As the
distance decreases, the time between the chimes gets shorter .
When the distance is less than
1 ft (0.30 m), the chime becomes a
continuous tone. Here, at the latest, you should stop backing up.
Please note that low objects already signaled by Audi Parking
System can become so close that they can no longer be detected
and will not continue to be signaled .
If the distance to an obstacle stays the same, the volume of the
distance signal chime is gradually reduced after about
4 seconds
(does not affect the continuous signal tone). Approaching another
obstacle will cause the distance signal to sound again at the normal
volume.
Distance signal tones
Distance is signaled by chimes from the rear signal generator. The
volume and the pitch of the chimes can be adjusted in the MMI

Rear-view camera (rear view)
The rear -view camera picture ~ page 175, fig. 179 appears in the
MMI Display as a mirror image . The rear-view camera picture has
orientation lines and marked surfaces projected into it, as an aid to
the parking process=>
page 173. The red line in the picture
=>
page 173, fig. 175 or=> page 173, fig. 176 indicates the collision
area . Here , at the latest, you should stop backing up~&.
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 terminal, the rear -view
camera picture disappears. The rear-view camera picture reappears
the next time you park.
When the rear -view camera picture is displayed, you can adjust the
volume and frequency of the acoustic parking via the control button
with the
Settings function ~ page 181.
Further information on the warning message and the MMI terminal
can be found in the MMI instruction booklet.
& WARNING
• Sensors have blind spots in which objects cannot be detected.
Be especially careful to check for small children and animals
before backing up. Small children and animals will not always be
detected by the sensors.
• The Audi Parking System is not a substitute for being careful
and alert when backing up. Be especially careful during parking
and similar maneuvers. Always watch where you are driving and
make sure that nothing is in the way.
• Remember that low obstacles which have already been
signaled may pass below the system's sensing zone when the
vehicle is backing up. The fact that the signal stops does not mean
that you have cleared the obstacle. When the signal stops, impact is imminent . Objects such as trailer hitches, chains, narrow posts
or fences covered by a thin layer of paint may not always be

Safety belts -----------------=------
• 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
ries.
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 posit ions reduce
the effectiveness of safety belts and w ill even increase the
risk of injury and death by moving the safety belt to critical
areas of the body . Improper seating positions also increase
the r isk 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 ::::;,

lt pretensioners
How safety belt pretensioners 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::::;,
6
in "Service and disposal of safety belt pretensioner" on page 214.
Taking up the slack helps to reduce forward occupant movement
during a collision.
0 Note
Never let the belt remain over a rear seat back that has been folded
forward.
[ i] Tips
The safety belt pretensioner can only be activated once.
• In minor frontal, side and rear -end collisions, in a rollover and in
accidents involving very little impact force, the safety belt preten­
sioner are not activated .
• When the safety belt pretensioners are activated, a fine dust is
released. This 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 system are scrapped . A qualified deal ­
ership is familiar with these regulations and will be pleased to pass
on the information to you.
• Be sure to observe all safety, environmental and other regula­
tions if the vehicle or individual parts of the system, particularly the
safety belt or airbag, are to be disposed . We recommend you have
your authorized Audi dealer perform this service for you. •

& WARNING (continued)
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer.
& WARNING
If, in exceptional circumstances, you must install a forward-facing
child restraint on the front passenger's seat:
• Always make sure the forward -facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger 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 rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible, before installing 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
and stays on all the time whenever the ignition is switched on. •
Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced Airbag System in it. These parts include the
weight-sensing mat, sensors, wiring, brackets, and more. The func­
tion of the system in the front passenger seat is checked by the elec ­
tronic control unit when the ignition is on. The control unit monitors
the Advanced Airbag System and turns the airbag 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 contains 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 .
The front Advanced Airbag System consists of the
following:
• Crash sensors in the front of the vehicle that measure vehicle
acceleration/deceleration to provide information to the Advanced
Airbag System about the severity of the crash.
• An electronic control unit, with integrated crash sensors for front
and side impacts. 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 with gas generator for the driver inside the
steering wheel hub .
• An Advanced Airbag with gas generator 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 electronic
control unit to regulate deployment of the front Advanced Airbag on
the passenger side.
• An airbag monitoring system and indicator light in the instru ­
ment cluster ~
page 226.
• The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument panel~
page 227, fig. 213 and tells you
when the front Advanced Airbag on the passenger side has been
turned off.
• A sensor below the safety belt latch for the front seat passenger
to measure the tension on the safety belt. The tension on the safety
belt and the weight registered by the weight -sensing mat help the
control unit "decide" whether the front airbag for the front ..

Airbag system -----------------=--=--------
passenger seat should be turned off or not~ page 217, "Child
res traints o n the fr ont sea t - som e impo rtant t hin gs t o know".
• A sensor in the safety belt latch fo r the drive r and for the front
s e at passe nger that s enses wh ether th at safe ty belt i s la tch ed o r not
and transmits this information to the e lectronic contro l unit.
& 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 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 dr iver seat from the
vehicle.
• Never remove the upholstery from the front passenger seat .
• Never disa ssemble 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 .
• Never store items under the front passenger seat . Parts of the
Advanced Airbag System under the pa ssenger 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.
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued )
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraints or occupants on the front passenger
seat and prevent the side airb ag 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-sens ing mat in the seat from accurately registering the
child re straint 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 manufa cturer's instru ctions requ ire the use
of a towel , foam cushion or something else to properly position
the child restraint, make certain 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 install child restraint in a rear seating position
and have the airbag system inspected by your Audi dealer. •
How the Advanced Airbag System
components
work together
The front Advanced Airbag System and the side airbags supplement
the protection offered by the front t hree -point safety belts with
pretens ioners and load limiters and the adjustable head restraints
to help reduce the risk of in jury in a wide range of accident and
c ras h situati ons . Be sure to read t he impo rtant informatio n abou t
safety and heed the WARNI NGS in th is chapter.
Dep loyme nt of the A dva nced Ai rbag Sys tem a nd the activati on of
the safety be lt pretensioners depend on the deceleration measured
by the c ra s h sens ors and regis te red by the electronic control unit.
Crash severity depends on speed and deceleration as we ll as the
mass and s tiff ness of the veh ic le or object invo lved in the crash.
