2015 AUDI A8 instrument panel

-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
er's instructions provided with the child
seat or carrier .
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can cause injury in a crash.
Front airbags
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>-

158 Airbag sys te m
- Never put the forward-facing child re­
straint up aga inst or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before installing
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit io n.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime 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, brack­
ets, and more. The function of the system in
the front passenger seat is checked by the
electronic control un it when the ign it ion is on .
The control unit mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on whe n a malfunction in the system
components is de tected. The function of the
ai rbag indicator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing 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 Airb ag System
con sis ts of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air­
bag System about the seve rity of the c rash.
- An electron ic co ntro l unit, w ith integ rated
crash sensors for fron t and side impacts.
T he contro l unit "dec ides " whether to fire
the front airbags based on the information received from the crash sensors . The contro l unit also "decides" whether the sa
fety be lt
pretensioners shou ld be activated.
- An Advanced Airbag with gas generato r and
contro l valve for the driver inside the steer­
ing wheel h ub.
- An Advanced Airbag with gas gene rator and
contro l valve inside the instrument panel for
the front passenger .
- A weight -sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat.
The informat ion registered is sent continu­
ously to the electronic control unit to regu­ late deployment of the front Advanced Air­
bag on the passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster~
page 161 .
-A sensor in each front seat registers the dis­
tance betwee n the respective seat a nd the
steer ing whee l o r inst rument panel. The in­
formation registered is sent cont inuous ly to
t he ele ctron ic contro l uni t to regula te de­
p loyment of the front Adva nced A irbags .
- The
PASSENGER AIR BAG OFF light comes
on and st ays on in the center of the instr u­
ment p anel
~page 162, fig. 168 and t ells
you when the front Advanced Airbag on the
passenger side has been turned off .
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension
on t he safety be lt . The tension on the safety
be lt and the weight registered by the
weight-sensing mat he lp the control unit
"decide" whether the front airbag for the
front passenger seat should be turned off or not
~ page 153, Child restraints on the
front seat -some important things to
know.
- A sensor in the safety belt latch fo r the driv­
er and fo r the fro nt seat passenger that
senses whether that safety bel t is latched or
no t and transmi ts this information to t he
electronic control unit.
A WARNING ~ -
Damage to the front passenger seat can
prevent the front airbag from work ing
properly.

¢ page 153.
A WARNING
A child in a rearward-facing child seat i n­
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 inflati ng a irbag w ill hit the child sea t
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 sea ts on
the rear seat .
- If you mus t install a rearward facin g
child seat on the front passenger seat
because of exceptiona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi ·
ately install the rear-facing chi ld seat in a
rear seating position and have the a irbag
system inspected by your Aud i deale r.
A WARNING
Objects be tween you and the a irbag will
increase the risk of i njury in a crash by i n­
terfering wi th the way the air bag unfolds
or by being pushe d in to yo u as the airbag
inflates.
- Never hold th ing s in your hand s or on
yo ur lap when the vehicle is in use.
- Never tran sport i tems on or in the are a
o f the front passenge r seat. Objects
cou ld move into the area of the front air ­
bags during braking or other s udden ma­
neuvers and become dangerous projec­
t il es that can cause serious persona l in­
jury if the airbags inflate.
- Never place or attach accessories or oth­
er objects (such as cup ho lders, tele­
phone brackets, large, heavy or bu lky ob­
jects) o n the doors, over or near the area

& WARNING
-=
The fine dust created when airbags deploy
can cause breathing prob lems fo r people
with a history of asthma or ot her breath­
ing cond itions.
- To reduce the risk of breath ing problems,
those with asthma or other respiratory
conditions shou ld get fresh air r ight
away by getting out of the veh icle or

& WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel horn pad or airbag cover
~r the instrument panel or modify them
in anyway .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units .
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your authorized Audi dealer or qualified work­
shop .
- Never modify the front bumper or parts
of the vehicle body .
- Always make sure that the side airbag can inflate without interference:
- Never install seat covers or replace ­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
Airbag system 165
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once . After an airbag has inflated, it
must be replaced by an authori zed Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
t enance booklet under
AIRBAG REPLACE­
MENT RECORD .
-For safety reasons in severe accidents,
the alternator and starter are separa ted
from the vehicle battery with a pyrotech ­
nic circuit interrupter .
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped , all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc .ca. gov/hazard o u swaste/ per­
chlorate . When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend that you have
your dealer perform this service for you.
•
•

Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety belts are a lways there to offer protec ­
tion in those acc idents in which airbags are
not supposed to deploy or when they have al­
ready deployed, for example when your vehi ­
cle str ikes or is struck by another afte r the
fi rst coll is ion.
This is just one of the reasons why an a irbag is
not a substitute for the safety belt . The airbag
system wo rks most effectively when used with
the safety belts . Therefore, always wear your
safety bel ts correctly .
It is important to remember that while the
supplemental knee a irbag system is des igned
to reduce the like lihood of serious injur ies,
o ther in juries , fo r example, swel ling , bruising
and minor abras io ns and frict ion bu rns ca n al ­
so occur when an airbag in flates.
The knee airbag system basically consists
of :
-The elec tronic control mod ule
- T wo inf latab le airbags (airbag and gas gen-
erato r), one for the driver and one for the
front passenger
- T he airbag ind icator light in the instrument
pane l
The knee airbag system will not deploy:
-when the ign ition is switc hed off
- in frontal collisions w hen the decelerat ion
measured by the control unit is too low
- in s ide collisions
- in rear-end collisions
- in ro llovers
- in the event of a system malfunct io n (wa rn -
i ng/indicator ligh t is on)
r::!> page 18.
& WARNING
- Safety belts and the airbag system can
only p rov ide protection when occ upants
are in the proper seating posit ion
c::>page 160.
-If the airbag indicator light c::> page 18
comes when the vehicle is be ing used,
have the system inspected immediately
A irba g sy stem 16 7
by your authorized A udi dealer. It is pos­
sib le that the airbag will inflate when it
is not supposed to , or will not inflate
when it should .
How knee airbags work
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
Fi g. 170 In flated a irbags protect ing in a fronta l co lli·
s ion
The knee airbag system has been designed so
that the airbags for the driver and front pas­
senger deploy in certain but not all frontal
collisions.
If the front a irbags dep loy, the knee a irbags
also dep loy in fronta l co llisions when the de­
ployment thresho ld stored in the control unit
is met.
When the system deploys, the ai rbags fill
with a propellant gas, and inflate between the lower part of the instrument panel and the
driver and the lower part of the instrument
panel and the front passe nger
c::> page 160,
fig . 167 .
Although they are not a soft p illow, they can
"cushion" the impact and in th is way they can
help to reduce the risk of injury to the lower
extremit ies .
A ll of this takes place in the blink of an eye , so
fast that many people don't even realize tha t
the a irbags have deployed . The airbags a lso
inflate with a great deal of force and it is im­
portant fo r occupant safety that nothing
shou ld be in their way when they deploy.
i,..

168 Airbag system
Fully inflated airbags in combination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the risk of injury.
Important safety instructions on the
knee airbag system
Airbags are only supplemental restraints. Al­
ways wear safety belts correctly and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety belts and
airbags to provide supplemental protection .
A WARNING
An inflating knee airbag can cause serious
injury. Wearing safety belts incorrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a vehicle is being used .
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad­
justing their seat positions, it is impor­
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru­
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­
ment panel.
- T he risk of personal injury increases if
you lean forward or to the side, or if the seat is improperly positioned and you are
not wearing your safety belt. The risk in­
creases even more should the airbag de­
ploy.
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter­
fering with the way the airbag dep loys or by being
pushed into you as the airbag
deploys.
- Never let anybody, especially children
o r anima ls ride in the footwell in front
of the passenger seat. If the airbag de­
ploys, this can result in serious or fatal
injuries.
- Never carry objects of any kind in the
footwell area in front of the driver's or
passenger's seat. Bulky objects (shop­
ping bags, for example) can interfere
with or prevent proper deployment of
the airbag. Small objects can be
thrown through the vehicle if the air­ bag deploys and injure you or your pas­
sengers.
- Make sure there are no cracks, deep scratches or other damage in the area of
the instrument panel where the knee air­
bags are located.
- If children are incorrectly seated, their
risk of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 171 S id e airbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests
¢ fig . 171 and the rear
backrest facing the doors. They are identified
by the word "AIRBAG".
The side airbag system basically consists of:
-the electronic control module and external
side impact sensors
