2015 AUDI A8 airbag

occupant will slam violently into the steering
wheel, instrument panel, windshield, or what­
ever else is in the way
c::> fig. 158. This impact
with the vehicle interior has all the energy
they had just before the crash.
Never rely on airbags alone for protection.
Even when they deploy, airbags provide only
additional protection. Airbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver, must
wear safety belts correctly in order to mini­
mize the risk of severe injury or death in a
crash.
Remember too, that airbags will deploy only
once and that your safety belts are always
there to offer protection in those accidents in
which airbags are not supposed to deploy or
when they have already deployed. Unbelted
occupants can also be thrown out of the vehi­
cle where even more severe or fatal injuries
can occur.
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passen­
gers in the rear seats endanger not only them­
selves but also the driver and other passen­
gers
c::> fig. 159. In a frontal collision they will
be thrown forward violently, where they can
hit and injure the driver and/or front seat pas­
senger.
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision. It's simply
not true!

Safety belts 145
Safety belts used properly can make a big dif­
ference. Safety belts help to keep passengers
in their seats, gradually reduce energy levels
applied to the body in an accident, and help
prevent the uncontrolled movement that can
cause serious injuries. In addition, safety belts
reduce the danger of being thrown out of the
vehicle.
Safety belts attach passengers to the car and
give them the benefit of being slowed down
more gently or "softly" through the "give" in
the safety belts, crush zones and other safety
features engineered into today's vehicles. By
"absorbing" the kinetic energy over a longer
period of time, the safety belts make the
forces on the body more "tolerable" and less
likely to cause injury.
Although these examples are based on a fron­
tal collision, safety belts can also su bsta ntia l­
ly reduce the risk of injury in other kinds of
crashes. So, whether you're on a long trip or
just going to the corner store, always buckle
up and make sure others do, too. Accident sta­
tistics show that vehicle occupants properly
wearing safety belts have a lower risk of being
injured and a much better chance of surviving
an accident. Properly using safety belts also
greatly increases the ability of the supplemen­
tal airbags to do their job in a collision . For
this reason, wearing a safety belt is legally re­
quired in most countries including much of
the United States and Canada.
Although your Audi is equipped with airbags,
you still have to wear the safety belts provid­
ed. Front airbags, for example, are activated
only in some frontal collisions. The front air­
bags are not activated in all frontal collisions,
in side and rear collisions, in roll overs or in
cases where there is not enough deceleration
through impact to the front of the vehicle.
The same goes for the other airbag systems in
your Audi. So, always wear your safety belt
and make sure everybody in your vehicle is
properly restrained!

A WARNING
- It is possible for the pretensioners to de­
ploy incorrectly.
- The pyrotechnic system can only provide
protection for one co llision. If the pyro­
technic pretensioners deploy, the preten­
sioning system must be replaced.
(D Tips
The pyrotechnic safety belt pretensioners
can only deploy once.
- The safety belt pretensioners do not de­
ploy in minor frontal and side collisions,
in rear-end collisions, in rollovers and in
collisions invo lving very litt le impact
force .
- A fine dust is released when the pyro­
techn ic safety belt pretens ioners deploy.
This is normal and is not caused by a fire i n the veh icle.
- The relevant safety requirements must
be obse rved when the vehicle or compo­
nents of the system are scrapped . A
qualified dea le rship is familiar with
these regulations and w ill be pleased to
pass on the informat ion to you.
- Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or indiv id ual parts of the system, par ­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your a uthorized Audi dea ler perform this
serv ice for you .
Service and disposal of safety belt
pretension er
The safety belt pretensione rs are parts of the
safety bel ts on your Audi . Installing, remov­
ing, servicing or repa iring of belt pretens ion ­
e rs can damage the safety be lt system and
prevent it from working correct ly in a colli­
sion.
There are some important th ings you have to
know to make sure that the effect iveness of the system wi
ll not be impaired and that dis­
carded components do not cause injury or pol­
l ute the environment .
A WARNING ,.__
Improper care, servic ing 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 act i­
vated only once. If belt pretensioners have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety be lt system.
- Safety belt systems including safety belt
pretens ioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposa l of th is system.
- For any wo rk on the safety belt system,
we strongly recommend that you see
your author ized Audi dealer or qualified
technician who has an Audi approved re ­
pair manua l, 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.
F or your safety and the safety of your passen­
gers, before driving off, always:
"" Adjust the driver's seat and steering wheel
properly¢
page 134,
"" Adjust the front passenger's seat properly
¢ page 59,
""Wear safety be lts properly ¢ page 146,
""Always properly use the proper child re-
stra int to protect ch ildren
r::::> page 174.
In a collision, airbags must inflate within the
blink of an eye and with considerable force.
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . T herefore in order to help the
a irbag to do its job, it is important, both as a
d river and as a passenge r to s it properly at all
times.
By keep ing room between your body and the
steer ing whee l and the front of the passenge r
compartment, the airbag can i nflate fully and
comp lete ly and provide supp lemen tal protec­
tion in ce rtain frontal collisions

There is a lot that the d river and the passen­
gers ca n and must do to help the individua l
safety features ins talled in your A ud i work to­
gether as a system.
P rope r seat ing pos ition is important so that
the front airbag on the dr iver s ide ca n do its
job. If yo u have a physical impa irment or con-
A irbag system 15 1
dition that prevents yo u from sitting properly
o n the driver seat with the safety belt properly
fastened and reach ing the peda ls, or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified wo rkshop, o r call Audi Customer Re­
l ations at 1-800-822-2834 fo r poss ible modi­
ficat io ns to your veh icle.
When the airbag system dep loys, a gas gener ­
ator will fill t he a irbags, break open the pad­
ded cove rs, and inflate between the steer ing
whee l and the dr ive r and between the instru­
ment pane l and the fron t passenger. The a ir­
bags will deflate immedia tely after dep loy­
ment so that the front occupants can see
thro ugh the windshie ld again witho ut inter­
ruption.
A ll of th is takes place in t he blink o f an eye, so
f ast 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 a irbags in combination with properly
wor n safety belts slow down and lim it the oc ­
c u pant's fo rward movement. Togethe r they
help to preve nt the drive r and front seat pas­
senger from h itti ng pa rts of the inside of the
vehicle while reducing the forces act ing 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 trigge ring of the airbag system
depends on the vehicle dece lerat ion rate
ca used by the co llision and registered by the
electron ic control unit. If t his rate is below
the reference value programmed into the con ­
tro l unit, the airbags will not b e trigge red,
even t hough the car may be bad ly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs or even the lack of ve hicle damage
is not necessarily an indica tion of whether an
airbag should inflate or not . .,. •
•

152 Airbag sys te m
Since the cir cumstances will vary considerab ly
between one collision and anot her, it is not
possib le to def ine a range of vehicle speeds
that will cover every possible k ind and angle
of impact t hat will always trigger the airbags.
Important factors include, for example, the
nature (hard or soft) of the object which the
car h its , the ang le of impact, vehicle speed ,
etc. The front airbags will also not inflate in
side or rea r collisions, or in ro ll-overs .
Always rememb er: Airbags will deploy only
once, and only in certa in k inds of co llisions .
Your safety belts are always there to offer 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 your ve­
hicle strikes or is struck by another vehicle af­
te r the first co llision .
This is just one of the reasons why an airbag is
a supplementary restraint and is not a substi­
tute for a safety belt . The airbag system
works most effect ively when used with the
safety belts. There fore, always properly wear
your safety belts¢
page 143.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will dec rease the effec­
t iveness of the airbags and will increase
the risk of personal injury in a collision .
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instrument pan­
el.
- If you cannot sit more than 10 inches
( 2 5 cm) from the s teer ing whee l, investi­
gate whethe r adaptive equipmen t may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You will also receive serio us injuries and
cou ld 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 risk of injury when an a ir­
bag inflates, always wear safety be lts
properly ¢
page 146, Safety belts.
-Always make certain that ch ildren age 12
or younger always ride in the rear seat. If
children are not properly restrained, they
may be severely injured or killed when an
airbag inflates .
- Never let children ride unrestrained or
improperly restrained in the vehicle. Ad ­
just the front seats prope rly .
- Never ride with the back rest reclined .
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 134.
-Always sit upright 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 floor in front of the seat to
help prevent serio us in ju ries to the legs
and h ips if the airbag inflates.
- Never recline the front passenger 's seat
to transport objects , Items can a lso
move into the a rea of the s ide airbag or
the front a irbag du ring bra king or in a
sudden maneuve r. Objects nea r the air ­
bags can become projectiles and cause
in jur y when an airbag inflates.
A WARNING ~
Airbags that have deployed in a crash must
be replaced.
- Use on ly orig inal equipment airbags ap­
proved by Aud i and installed by a trained
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
p lace any airbag in your vehicle and as­
sure system effectiveness in a crash .
- Never permit salvaged or recycled air­
bags to be installed in your vehicle .

Child restraints on the front seat - some
important things to know
.. Be sure to read the important informat ion
and heed the WARNINGS for important de­
tai ls about chi ldren and Advanced Airbags
~ page 174.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
a ll chi ldren, especially those 12 years and
younger, a lways ride in the back seat properly
restra ined for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to r ide .
The front seat is not the safest place fo r a
chi ld in a fo rward-facing chi ld seat. It can be a
very dange ro us p lace for an infant or a ch ild in
a rearward -facing seat.
The Advanced Airbag System i n your veh icle
h as been cert ified to comp ly with the require­
men ts of Uni ted States Federa l Mo to r Veh icle
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 turne d off ("sup­
p ressed") if a chi ld up to about one year of
age restrained in one of the rear -facing or for­
ward -facing infant restraints listed i n 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 . For a listing of the child re­
straints that we re used to certify compliance
with the US Safety Standard ~

A irbag sys tem 153
- will go off if the front passenger seat is oc ­
cupied by an adult as registered by the
weight -sensing mat ¢
page 161, Monitor­
ing the Advanced Airbag System.
T he PASSENGER AIR BAG OFF light comes on
whe n the contro l unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag to be turned off.
If the total weight on the front passenge r
seat is more than that of a typical 1 year-old
c h il d but less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENGER
AIR BAG OFF
light does not come on, the
front a irbag on t he passeng er side has not
been turned off by the elect roni c con trol unit
and can deploy if the control unit senses an
impact that meets the cond it ions stored i n its
memory .
For exampl e, th e airb ag may deplo y if:
- a small ch ild that is heav ie r than a typical 1
year-old ch ild is o n the front passenger seat
(regard less of whether the child is in one of
the ch ild seats l isted ¢
page 176), or
- a child who has outgrown chi ld restraints is
on the front passenge r seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ument cluster and stays on .
The front airbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
l ight does not illum inate and stay lit) even if a
small ad ult o r teenager, or a passenger who is
not sitti ng uprig ht w ith their back against a
non -recli ned back rest w it h thei r feet on t he
vehicle floor i n front of the sea t is on t he front
passenger seat

If the fron t passenger ai rbag dep loy s, the
Federa l Standard req uires the airbag to meet
the "low risk" dep loyment criteria to reduce
the ris k of injury t hrough interact ion w ith the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions ..,_ •

Q page 162, PASSENGER AIR BAG OFF light.
A lways remember, a chi ld seat or infant carr i­
e r i nsta lled on the front seat may be struck
and knocked out of position by the rapidly in ­
flating passenger's airbag in a frontal colli­
sion. The airbag could greatly reduce the ef­
fectiveness of the chi ld restraint and even se­
riously injure the child during inflat ion.
F or this reason, and because the back seat is
the safest p lace for chi ldren -when properly
restra ined accord ing to their age and si ze -we
strongly recommend that children always sit
in the back seat
Q page 174, Child Safety .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child seat
or infant carrier w ith great force and w ill
smash the ch ild seat and child against
the backrest, center armrest, door or
roof .
- Always install rear -facing child seats on
the rear seat .
- If you must install a rearward facing
child seat on the f ront passenge r seat
because of except iona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately i nstall the rear-facing chi ld seat in a
rear seating position and have the airbag
system inspected by your Aud i dealer .
- Forward-fac ing ch ild seats installed on
the front passenger's seat may interfere
with the deployment of the airbag and c ause se rious pe rsonal injury to the
c hild.
A WARNING
If, in exceptional c ircumstances, you mus t
install a forwa rd-facing child restra int 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 s ide a irbag .
- Never put the forward-facing child re­
straint up against or very near the instru­ ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore a nd
aft adjustment range, as fa r away from
the airbag as possible before installing
the forwa rd-fa cing ch ild restra int. The
b ackrest mus t be ad justed to an up right
position.
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays o n all the
time wheneve r the ignition is switched
on.
A WARNING -ra----
To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light will be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is sw itched on.
- If the
PASSENGER AIR BAG OFF light
does not stay on, perform the checks de­
scribed

vanced Airbag System .
-Take t he 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
light does not stay on.
- Have the airbag system inspected by
your Aud i dea le r i mmediately .
- Always carefully follow instr uctions from
child restraint manufacture rs when in­
stall ing c hild restra ints .
A WARNING
If, in except iona l circumstances, you m ust
i nstall a forward o r rearwa rd-fa cing child
r estra int on the front p assenger's se at:
- I mp roper installation of ch ild restra ints

-An improperly installed child restraint
can interfere with the airbag as it de ­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­

Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occupants.

s trument pan el
Your vehicle is equipped with an "Advanced
Airbag System " in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured. he safety belts for
the seats have "pretensioners" that he lp to
take slack out of the belt system. The preten-
Airbag system 155
sioners are also activated by the electronic
control unit for the airbag system.
The front safety belts also have load limiters
to help reduce the forces applied to the body in a crash.
The airbag for the driver is in the steering
wheel hub
i=;, fig . 165 and the airbag for the
front passenger is in the instrument panel
i=;,fig . 166 . The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air­
bags in your vehicle. We urge you to read the
detailed information about airbags, safety
belts and ch ild safety in th is and the other
chapters that make up the owner's literature.
Please be sure to heed the WARNINGS -they
are extremely important for your safe ty and
the safety of your passengers, especially in ­
fants and small children.
_& WARNING
Never rely on airbags alone for protection .
- Even when they deploy, airbags provide only supplementa l protection.
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts
and make sure that everybody in your ve­
hicle is properly restrained.
_& WARNING
A person on the front passenger seat , es­
pecially infants and small children, will re­
ceive serious injuries and can even be kil-
led by being too close to the airbag when
it inflates .
- Altho ugh the Advanced Airbag System in
your vehicle is designed to turn off the
front passenger airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these special conditions is impossible in all conceiva­
ble situations that may happen during
-
the useful life of your vehicle . 11>-

156 Airbag sys te m
- The Advanced A irbag System can deploy
in accordance with the "low risk" opt ion
under the U.S. Federa l Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other cond itions for airbag de­
ployme nt are met.
- Acc ident statist ics have shown that chi l­
dren are generally safer in the rea r seat
area than in the front seating posit io n.
- For their own safety, all children, espe­
cially 12 yea rs and younger, sho uld a l­

Advanced front airbag system
Your veh icle is eq uipped wit h a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Saf ety Standard
208 as applicab le at the time your vehicle was
manufactured.
The front Advanced Airbag System supp le­
ments the safety belts to provide addit iona l
protection for the drive r's and front passeng ­
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle dece lerat io n is high enough .
The front Advanced Airbag System for the
front seat occupants is not a substitute fo r
your safety belts. Rather, it is part of t he over­
all occupa nt restraint system in your ve hicle.
A lways remember that the airbag system can
on ly help to protect you , if you are s itting up­
r ight, wearing yo ur safety belt and wea ring it
p roperly . This is w hy you and yo ur passenge rs
must always be properly restrained , not just
beca use the law requires you to be.
The Advanced Airbag System in your veh icle
h as been cer tified to meet the " low r is k " re­
qu irements for 3 and 6 year -o ld children on
the passenger side and very small adu lts on
the driv er side. The low risk deployment crite ­
ria are intended to he lp red uce the risk of in­
jury through interaction with the front airbag that can occur, fo r example, by be ing too close to the steering wheel and instrument
pane
l when the airbag inflates .
In add ition, the system has been certified to
comply wi th the "s uppression" re qu iremen ts
of the Sa fe ty Standard , to turn
off the front
airbag for infants 12 months o ld and younger
who are rest rained on the front passenger
seat in child restraints that are listed in the Standard
¢ page 176, Child restraints and
Advanced Airbags .
"Suppression" requires the front a irbag on the
passenger side to be tu rned
off if:
- a child up to abo ut one year o f age is re ­
strained on the front passenger seat i n one
of the rear-fac ing or forward -facing infant
restraints listed in Federal Motor Vehicle
Safety Standard
208 with which the Ad­
vanced Airbag System in your vehicle was
cert ified . For a listing of the ch ild res traints
