& WARNING
• The rear-view camera has 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 hit ches, chains , narrow posts
& WARNING (continued )
or fences covered by a thin layer of paint may not always be
detected by the sy stem. They can still damage your vehicle
without warning .
• Always make sure that the volume and frequency of the chime s
is adjusted so that you can easily hear the acoustic distance signal
even if the radio is playing , the air -conditioner blower is on High or
there is a high level of outside noise .
- Check the settings whenever someone else has driven the
vehicle before you .
• Improper reliance on the Audi Parking System can cause colli ­
sions and serious personal injury .
- Never rely only on parking assi st w hen changing backing up .
- Always check rear view mirrors to make sure it is safe to back
up .
[ i ] Tips
• Before parking with the rear -view camera, the Adaptive Air
Su spensi on* co mfort or automatic mode must be switched on

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 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 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 pos i­
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 205. •
Safety belt tensioners
How safety belt pretensioners work
In front, side and rear 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 collisions of
great severity . This tightens the belt and takes up belt slack~
& in
"Service and disposal of safety belt pretensioner" on
page 211.
Taking up the slack helps to reduce forward occupant movemen t
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. •

• If you must in stall 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 circumstance s, you must install a forward-facing
c hild 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

& 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 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 things on your lap or carry objects on the
passenger seat. Such items can increase the weight registered by
the weight-sens ing 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.
& 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 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 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
i nstalled 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. •

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 207 Side airbag
location in the driver 's
seat
The side airbags are located in the sides of the front seat backrests
~ fig. 207 and the rear backrest * facing the doors. They are identi ­
fied by the word "AIRBAG" .
The side airbag system basically consists of :
• the electronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
• two rear side airbags (as an ordered
option)
• the airbag warning light in the instrument cluster .
The airbag system is monitored electronically to make certain that
it is functioning properly at all times. Each time you turn on the igni ­
tion, the airbag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety belts and can help
to reduce the risk of injury to the driver's , front and rear*
passenger's upper torso on the side of the vehicle that is struck in a
side collision . The airbag deploys only in side impacts and only
when the vehicle acceleration registered by the control unit is high
