Safety belt pretensioners
The safety belts are equipped with a belt p re­
tensione r that helps to t igh ten the safety be lt
and remove s lack when the pretensione r is ac­
tivated. The function of the pretensioner is monitored by a warning light

-Safety belts offer optimum protection
only when the seatback is upright and
belts are properly positioned on the
body .
-
-Never attach the safety belt to the buck ­
le for another seat . Attach ing the belt to
the wrong buckle will reduce safety belt effect iveness and ca n cause seri ous per­
sonal in jury.
- A passenger who is no t properly rest rain­
ed can be se rio usly inju red by the safety
belt itself when it moves from the stron­
ger parts of the body into critical areas
like the abdomen .

all veh icle occupants and especially for chil­
dren. Therefore:
• Never pe rmit anyone to assume an incorrect
sitting position in the vehicle while traveling

Safety belt preten­
sioners
How safety belt pretensioners work
In front and side collisions above a particular
severity, safety belts in use are tensioned au­
tomatically.
The safety belts are equipped with safety belt
pretensioners. The system is activated by sen­
sors in front and side collisions of great se­
verity. This tightens the belt and takes up belt
slack
Q &. in Service and disposal of safety
belt preten sioner on page 113.
Taking up the
slack helps to reduce forward occupant move­
ment during a collision .
@ Tips
The safety belt pretensioner can only be
activated once.
- In minor frontal and side collisions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
force, the safety belt pretensioner are not activated.
- When the safety belt pretensioner is ac ­
tivated, 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 compo­
nents of the system are scrapped. A
qualified dealership is familiar with
these regulations and will be pleased to
pass on the information to you.
Safety belts 113
-Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or individual parts of the system, par­
ticularly the safety belt or airbag, are to be disposed. We recommend you have
your authorized Audi dealer perform this service for you.
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety belts on your Audi. Installing, remov­
ing, servicing or repairing of belt pretension­
ers can damage the safety belt system and
prevent it from working cor rectly in a colli­
sion.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and tha t dis­
carded componen ts do no t cause injury or pol­
lute the environment .
& WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly :
- The belt pretensioner system can be acti­
vated only once. If belt pretensioners
have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety belt system .
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has an Audi approved re­ pair manual, training and special equip­
ment necessary . •

Airbag system Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper 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 ¢
page 99,
"" Adjust the front passenger's seat properly
¢page 67 ,
""Wear safety be lts properly r::::> page 109,
""Always properly use the proper child re-
straint to protect children
r::::> page 136.
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 are 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 s it properly at all
times.
By keeping room between your body and the
steering whee l and the front of the passenger
compartment, the airbag can inflate fully and
comp letely and provide supplemental protec­
tion in certain frontal collisions
r::::> page 99,
Proper occupant seating positions. For details
on the operation of the seat adjustment con­
trols ¢
page 67 and ¢ page 68.
It's especially important that children are
properly restrained
r::::> page 136.
There is a lot that the driver and the passen­
ger can and must do to help the individua l
safety features installed in your Audi work to­
gether as a system.
Proper seating pos ition is important so that
the front airbag on the driver side can do its
job. If you have a physical impairment or con-
Airbag system 115
dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the pedals, or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your authorized Audi dealer or
qualified workshop, or call Audi Customer
CARE at 1-800-822-2834 for possible modifi­
cations to your vehicle .
When the airbag system dep loys, a gas gener ­
ator will fill the a irbags, break open the pad­
ded covers, and inflate between the steer ing
wheel and the driver and between the instru­
ment panel and the front passenger. The air­
bags will deflate immediately after deploy­
ment so that the front occupants can see
through the windshield again without inter­
ruption.
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 a lso
inflate with a great dea l 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 oc ­
cupant's forward movement. Together they
help to prevent the driver and passenger from
hitting parts of the inside the vehicle while re­
ducing the forces acting on the occupant dur­
ing 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 wi ll not inflate in all fronta l
collisions . The triggering of the airbag system
depends on the vehicle dece leration rate
caused by the co llision and registered by the
electronic control unit. If this rate is below
the reference value programmed into the con­
trol unit, the airbags will not be triggered,
even though the car may be badly damaged as
a result of the collision . Veh icle damage, re­
pair costs or even the lack of veh icle damage
is not necessarily an indication of whether an
airbag should inf late o r not.
It is not possib le to define a range of vehicle
speeds that w ill cover every possible kind and ..,. •

116 Airbag sys te m
angle of im pact that will always trig ger the
airbags, since the circumstances wi ll vary con­
siderably between one collision and another.
Important factors include, for example, the
nature (hard or soft) of the object which the
car h its, the angle of impact, vehicle speed,
etc. The front airbags will also not inflate in
side or rear collisions, or in roll-overs .
Always remember : Airbags will deploy only
once, and only in certa in kinds of collisions.
Your safety belts are always there to offe r pro­
tection in those s ituations in which airbags
a re not supposed to deploy, or when they have
a lready deployed; for example, when yo ur ve­
h icle strikes or is st ruck by another after the
first collision .
This is just one of the reaso ns why an a irbag is
a supplementary restra in t and is no t a s ubst i­
tute for a safety be lt. The airbag system
works most effective ly when used with the
safety be lts. Therefore, always properly wear
your safety belts¢
page 107.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will decrease the effec­
tiveness of the airbags and will increase
the risk of pe rsonal injury in a collision .
- Never sit closer than 10 inches (25 cm)
to the stee ring wheel or instr ument pan­
el.
- If you cannot sit more than 10 inches
(25 cm) from the steer ing wheel, investi­
gate whethe r adaptive equipment may
be available to held you reach the pedals
and incre ase your sea ting dis tance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of posi tion in any
way, your risk of injury is much higher.
- Yo u w il l a lso receive serio us in juries and
co uld even be killed if you are up against
the airbag or too close to it when it in ­
flates -even with an Advanced Airbag.
- To reduce the r is k of i njury when an air ­
bag inf lates, a lways wear safety belts
properly
c::> page 110, Safety belts .
-If ch ildren are not properly restra ined,
they may be severely injured or killed
when an airbag inflates.
- Never let ch ildren ride unrestrained or
improperly restrained in the vehicle. Ad­
just the fro nt seats properly.
- Always sit as far as possible from the steer ing whee l or the instrument pane l
¢ page 99, Proper occupant seating po­
sitions.
- Always sit uprig ht with your back against
the backrest of your seat.
- Never p lace your feet on the instrument
panel or on the seat. Always keep both
feet on the f loor in front of the seat to
he lp prevent serio us in ju ries to the legs
a nd h ips if the airbag inflates.
A WARNING
A irbags that have deployed i n a crash must
b e repla ced.
- Use on ly or ig inal equipment airbags ap­
p roved by Aud i and installed by a trained
technici an who has the necessa ry too ls
an d diagnost ic equipment to properly re­
p lace any airbag in your vehicle an d as­

- Never permit salvaged or recycled air ­
bags to be installed in yo ur vehicle.
Child restraints on the front seat - some
important things to know
.. Be sure to read the important information
and head the WARNINGS for important de ­
tails about children and Advanced A irbags
¢page 136.
The airbag on the passenger side makes the
front seat a potentia lly dange rous place fo r a
c hi ld to ride. The front seat is not the safest
place fo r a child in a fo rward-facing child safe­
ty seat.
It can be a very d angerous p lace for a n
infant or a chi ld in a rearw ard-f acing seat.
T he Advanced A irbag System in you r vehicle
has been ce rtified to comply wit h the Require ­
ments of Un ited States Fede ral Motor Vehicle .,.

Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be t urned off ("sup­
pressed") if a child up to about one year of
age restrained in one of the rear -facing or for­
ward -facing infant restra ints listed in Federal
Motor Vehicle Safety Standard 208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed o n the front
passenger seat. Fo r a listing of the child re­
straints that were used to certify compliance
with the US Safety Standard
q page 138.
The PASSENG ER AIR BAG OFF light in the in­
strument panel tells you when the front Ad­
vanced A irbag on the passenger side has bee n
turned off by the e lectronic control u nit.
Each t ime you turn on the ignition, the
PAS ­
SENGER AIR BAG OFF
l ight w ill come on for a
few seco nds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small child or ch ild
restraint on the front passenger seat,
- wi ll go off if the front passenger seat is oc­
cupied by an adult as registered by the
weight-sensing mat
q page 125, Monitor­
ing the Advanced Airbag System.
The PASSENGER AIR BAG OFF light comes on
when the control un it detects a total weight
on the front passenger seat that requires the
front airbag to be tu rned off .
If the total weight on the front passenger
seat is more than that of a typical 1 year-old
chi ld but less than the weight of a sma ll
ad ult, the front airbag on the passenge r side
can dep loy (the
PASSENGER AIR BAG OFF
light does not come o n). If the PASSENGER
AIR BAG OFF
l igh t does not come on, the
front airbag on the passenger side has not
been turned off by the electronic control unit
and can dep loy if the control u nit senses an
impact that meets the conditions stored in its
memory.
For example , the airbag may deploy if :
Airbag system 117
- a small ch ild that is heav ie r th an a typical 1
year -old chi ld is o n the front passenger seat
(regard less o f whether the child is in one o f
the child safety seats listed
q page 138), or
- a child who has outgrown child restraints is
on the front passenger seat.
I f the front passenger ai rbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ument cluster and stays on .
T he front airbag on the passenge r side may
not deploy (t he PASSENGER AIR BAG OFF
light does not illuminate a nd stay lit) even if a
small ad ult o r teenager, or a passenger who is
not sitting upright with their back against a
non-recl ined backrest w ith their feet on the
vehicle floor in front of the seat is on the front
passenger seat ¢
page 99, Proper seating po ­
sition for the driver.
If the front passenger airbag dep loys, the
Federa l Standard requ ires the airbag to meet
t h e "low risk" dep loyment criteria to reduce
t h e risk of injury th rough inte ract ion w ith the
airbag. "Low risk" deployment occurs in those
crashes that ta ke pla ce at lower dece le rat io ns
as de fined in the e lectronic co ntrol unit
¢ page 1 26, PASSENG ER AIR BAG O FF light.
Always remember, a c hild safety seat o r in fant
car rie r in st alled on the fron t seat may be
stru ck and kno cked ou t of po sitio n by the rap­
i dly i nflat ing passenger 's airbag in a fronta l
collision. The ai rbag co uld great ly red uce the
effectiveness of the chi ld restraint and even
seriously in jure the child during inflation.
For t his reason, and because the back seat is
the safest place for c hildren - when proper ly
rest rained according to their age and size -we
strong ly recommend that chi ldren a lways sit
i n the back seat¢
page 136, Child Safety .
A WARNING
-
A child in a rearward-facing ch ild safety
seat ins talled on the fron t passenger seat
will be ser io us ly injure d and can be killed if
the front airbag inflates -even with an Ad-
v anc ed Airbag System . ..,_

118 Airbag sys te m
- The inflati ng airba g will hit the child
safety seat or infant carrier w ith great
force and w ill smash the ch ild safety seat
and child against the backr est, door or
ro of.
- If you must install a rearwar d facing
child safety seat on the front passenger
seat b ecause of exceptional circ umstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
med iately install the rea r-facing child
safety seat in a rear seating position and
have the a irbag system inspected by your
Audi dealer .
- Forward -fac ing ch ild safety seats instal­
led on the front passenger's seat may in­
terfere with the deployment of the air­
bag and cause serious personal injury to
the ch ild.
A WARNING
If, in exceptional c ircumstances, you must
install a forward-facing child restra int on
the front passenger's seat
- Always make sure the forward-fac ing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward-facing child re­
straint up aga inst or very near the inst ru­
me nt pane l.
- Always move the passenger seat into its
rearmost position in the seat 's fore and
aft adjustment range, as far away from
the a irb ag as poss ible be fore instal ling
the fo rward-facing child restraint. T he
backrest must be adjusted to an upright
position .
- Make su re that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime whenever the ignition is switched
on.
A WARNING
To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light will be d isplayed whenever a ch ild re- straint is
insta lled on the front passenger
seat and the ignition is sw itched on.
- If the
PASSENGER AIR BAG OFF light
does not stay on, per form the checks de­
scribed ¢
page 125, Monitoring the Ad­
vanced Airbag System.
- Ta ke the chi ld restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN ­
GER AIR BAG OFF
l ight does not s tay on.
- Have the airbag system inspected by
your Aud i dea le r i mmediately .
- Always carefully follow instructions from
child restraint manufacture rs when in­
stalling child restra ints.
