2011 AUDI A5 CABRIOLET warning light

-Airbag system ------=-~-----------------------------------
& WARNING (conti nued)
• Always make sure that the side a irbag can inflate without
interference :
- Never in stall seat covers or replacement uphol stery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use addit ional se at cushions that cover the areas
where the side ai rbags inflate.
- Damage to the or iginal seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an author ized Audi dealer.
• The airbag system can be activated only on ce. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the techni cal information, t raining
and special equipment necessary.
• The airbag sy stem can be deploy ed only once. After an airbag
has been dep loyed , it must be replaced with new replacement
parts designed and approved e specially for your Audi model
version. Replacement of complete airbag systems or a irbag
components must be performed by qualified workshops onl y.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• In accidents when an airbag is deployed, the vehicle battery
separates the alternator and the starter from the vehicle electrical
system for safety reason s with a pyrotechnic circuit interrupte r.
- Work on the pyrotechnic circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter is sc rapped , all appli ­
cable safety precautions must be followed.
W For the sake of the environment
Un deployed ai rbag modu les and p retensione rs might be class ified as
Perch lorate Materia l -special handling may ap ply, see
www.dts c.ca.gov/ha za rdouswas te/pe rchlorate. When the vehicle or
parts of the restraint system includ ing a irbag modu les safety belts
w it h pretensioners are s crapped, all appli cable laws and regula tions
must be observed. Your author ized Aud i dealer is familiar with these
req uiremen ts and we recommen d that you have your dealer perfo rm
this serv ice for you. •
Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
t h e Advan ced Airbag System pe rforms in a cr ash . For e xamp le, usi ng
tire-rim combinations not app roved by Audi, lowering the vehicle,
c hang ing the stiffness o f th e suspension, incl uding the sp rings,
suspension struts, shock absorbers etc. can change the forces that
are meas ure d by the a irba g sensors and sent to the ele ct ronic contro l
unit . Some suspension changes can, fo r exam ple, increase the force
levels measured by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had no t been
ma de . Other kinds of changes may reduce the force levels meas ured
by the sensors and p revent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front
p as senge r se at tell the e lectroni c cont rol mo dule if the sa fe ty belt is
latched or not . If the safety belt is being used, t he front a irbag w ill
dep loy a t a s lightly h igher r ate o f vehicle decele ration t han if t he
safety belt is not be ing used . Therefo re, in a par ticular collis io n, it is
possible that an a irba g w ill not dep loy at a seating position where the
safety belt is being used but w ill inflate at the posit ion where the
safety belt is not be ing use d. It is im portant that nothing interfere
w it h t he safety belt bu ckles so that the sensors can se nd the co rrect
info rmation about safety be lt use to the electronic contro l unit.

are wearing your safety belt and wearing it properly. This is why you
should always wear your safety belt, not just because the law requires
you to do so:::::,
page 189, "General notes".
The safety belt buckle for the driver and front seat passenger have
switches that tell the airbag control module if the safety belt is being
used or not. If the safety belt is being used, the knee airbag will
deploy at a slightly higher rate of deceleration than if the belt is not
being used. Therefore, in a particular collision, it is possible that an
airbag will not deploy at a seat ing position where the safety belt is
being used but will inflate at the position where the safety belt is not
being used.
Remember too, airbags w ill deploy only once and only in certa in kinds
of accidents -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, for example when your vehicle strikes or
is struck by another after the first collision .
This is just one of the reasons why an airbag is not a substitute for the
safety belt. The airbag system works most effectively when used with
the safety belts . Therefore, always wear your safety belts correctly .
It is important to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associated with airbags.
The knee airbag system basically consists of:
• The electronic control module
• T wo inflatable airbags (airbag and gas generator), one for the
dr iver and one for the front passenger
• The airbag indicator light in the instrument panel
The knee airbag system will not deploy:
• when the ignition is turned off
• in front-end collisions when the deceleration measured by the
control unit is too low
• in s ide collisions •
in rear-end collisions
• in rollovers
• in the event of a system ma lfunction (warning/indicator light illu­
m ina ted):::::,
page 14.
& WARNING
• Safety belts and the airbag system can only provide protection
when occupants are in the proper seating position :::::,
page 208.
• If the airbag indicator light comes when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to deploy the airbag.

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants .
Fig. 202 S ide airbag
l o cat ion
in the d rive r's
s e at
The side airbags are located in the sides of the front seat backrests
~ page 218 , fig. 202. They are identified by the word "AIRBAG".
The side airbag sy stem basicall y consists of :
• the electronic control module and external s ide impact sensors
• t he two side airbags located in t he sides o f the front backrests
• the airbag warning light in the instrument cluster.
T he airbag sys tem is moni tore d ele ct ronically to make certa in that it
is funct ioning properly at all times. Each time you turn on the igni­
t ion , the airbag system indicator light w ill come o n for a few seconds
(self diagnostics) .
The side airbag system supp lements the safety belts and can he lp to
red uce the risk of injury to the drive r's an d front passenge r's upper
torso on the s ide of the vehicle that is struck in a side collision . The
a irbag dep loys o nly in side impac ts an d only when the veh icle acceler ­
ation registered by the contro l unit is h igh eno ugh. If this rate is
below the refe rence val ue p rogrammed into the control u nit, t he side
airbags will not be triggered, eve n thoug h the car may be badly damaged as a resu
lt of the collision. It is not possib le to define an
air bag trigger ing range tha t w ill cove r eve ry poss ible an gle o f imp act,
since the circumsta nces will vary considerab ly between one collision
and another . Important factors incl ude, for example, the nature
(hard or soft) of the impact ing object, the a ngle of impact, vehicle
speed, etc.~
page 219, "Important safety instructions on the side
airbag system" .
Aside from the ir normal safety function, safety be lts work to he lp
keep the driver or fron t passenger in po sit io n in t he event of a side
collision so that the side airbags ca n provide p rotect ion.
T he a irbag system is
not a substitute for your safety be lt. Rather, it is
pa rt of the ove rall occupant res trai nt system in your veh icle. Always
remember that the side airbag system can only help to protect you if
you a re wear ing yo ur safety belt and wea ring it properly. This is
another reason why you shou ld always wear your safety belts, not just
bec ause t he law requires you to do so~
page 189, '' Genera l no tes ".
It is important to remember that while the supp lemental s ide airbag
system is designed to red uce the lik elihood o f serious injuries, other
injuries, fo r example, swe lli ng, br uis ing , and minor abras io ns can
also be assoc iated w ith deployed side airbags. Remember too, side
airbags will de ploy only once and only in cert ain kinds of acc idents -
your safety belts are a lways there to offer protection.
Vehicle dam age, re pair costs o r even the la ck of vehicle dam age are
not necessarily an ind ication of over-sensitive or failed airbag activa­
t ion. In some collisions, both front and side airbags may infla te .
Remember too , tha t airbags will de ploy only once and only in certa in
kinds of collisions -yo ur sa fety bel ts are a lways the re to offe r protec ­
tion i n those accide nts in which airbags ar e not s upposed to deploy o r
when they have already dep loyed.
The side airbag system will not deploy:
• when the ign ition is turned off
• in side co llisi ons when the accelerat ion measured by the sensor is
t oo low
• in front -end col lisions ._

• in rear-end collisions
• in rollover s.
In some types of accide nts the front a irbags a nd side a irbags may be
t rig gere d together.
& WARNING
• Safety belts and the airbag system will only provide prote ction
when occupants are in the proper seating position=> page
219 .
• If the airbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle acceleration in a side collision is high enough to activate the
airbag. •
How supplemental side airbags work
Side airbags deploy ins tan tly an d can help reduce the risk
o f upper torso injuries for occupants who are properly
restrained.

If, in exceptional circumstances, you must install a forward-facing
child res traint on the front pas senger's seat:
• Always make sure the forward-facing seat has been designed
and certified by it s manufacturer for use on a front seat with a
passenger front and side airbag.
• Always follow the manufacturer 's instruction s provided with
the child safety seat or carrier.
• Always move the passenger seat into it s rearmost position in
the seat 's fore and aft adjustment range, as far away from the
airbag as possible before installing the child restraint. The back­ rest must be adjusted to an upright position.
• Always make sure that the PASSENGER AIR BAG OFF light
comes on and stays on all the time whenever the ignition is
switched on .•
Advanced front airbag system and children
Your vehicle is equi pped wi th a fron t "Advanced Airbag System" in
compliance with United States Federal Motor Vehicle Safety Standard
( F MVSS) 2 08 as appli ca ble at t he time your ve hicle was manufa c­
tured. The Advanced A
irbag system in yo ur vehicle has been certif ied to
mee t the "low -r is k" requiremen ts fo r 3-and 6-ye ar old ch ildre n on
t he passenger side and small adults on the dr iver side . The low risk
dep loyment criteria are inten ded to reduce the risk of injury through
interaction with the a irbag t hat can occur, for example, by being too
close to the stee ring wheel an d instr ument panel when the airbag
inflates. In addi tion, the system has been certified to comp ly with t he
"suppression" requirements of the Safety Standa rd, to t urn off the
fron t air bag for infan ts up to 1 2 months who a re res train ed on the
front passenger seat in child restrai nts that are listed in the Stan­
d ar d.
Even thoug h your vehicle is equipped with an Advanced Airbag
system , a ll ch ildren, especially those 12 years and yo unger, should
always r ide in t he back seat p roperly restrained for t heir ag e and si ze .
Th e ai rbag on the passenge r si de makes the front seat a potentia lly
dange rous p lace for a child to r ide. Th e front seat is not th e safest
place fo r a child in a forward-facing c hild safety seat. It can be a very
d an ge rous p lace for a n infan t or a large r chil d i n a rea rwa rd-facing
seat. •
Advanced Airbags and the weight-sensing
mat in the front seat
Th e Advanced A irbag System i n your ve hicle de tects t he p resence o f
an infa nt o r ch ild in a child rest rai nt on the fro nt passenger sea t using
the we ight-sens ing mat in the seat cushion and the senso r be low the
saf ety belt la tch o n th e front passenge r seat tha t measur es t he
tension on the safety belt.
Th e weigh t-sens ing ma t me asures tot al we ight of the child and the
child safety seat and a child blanket on the fro nt passe nger seat . The
we ight on the fro nt passenger se at is re lated to t he design of the
child res traint and i ts "footpri nt", the size and shape of t he bottom
of the ch ild restraint as it sits o n the seat . The weight of a child
restrain t an d its "foo tpr int" vary for differe nt k inds of child res tra ints .,_

and for the different models of the same kind of child restraint
offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor­
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the
PASSENGER AIR
BAG OFF
light.
Controls and equip­ ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot­
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with
t he requirements for advanced airbags with each and every chil d
restra int that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States Nationa l Highway Traffic Safety
Administration has published a list of specific type, makes and
mode ls of child restra ints that must be used to cert ify compliance of
the Advanced Airbag System in yo ur vehicle with the suppression
requirements of Federal Motor Veh icle Safety Standard 208. These

Important safety instructions for using
child safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of everybody
in th e veh icle, especially children :
- Always use the right child safety seat for each child and
always use it properly=>
page 22 7.
- Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat .
- When using the vehicle safety belt to install a child safety
seat, you must first activate the convert ible locking
retractor on the safety belt to prevent the child safety seat
from movi ng =>
page 231.
- Push the child safety seat down wit h your full weig ht to
get the safety belt really tight so that the seat cannot move forward or sideways more than one inch (2.5 cm). ._

____ C_ h_ i _l_d _S_ a_f _e _ty ~ --------------------------------------------
& WARNING (cont inued)
• If exceptional circumstances require the use of a forward­
facing child restraint on the front passenger's seat, the child's safety and well-being require that the following special precau­
tions be taken:
-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.
- Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier.
- Always move the front passenger seat into the rearmost
position of the passenger seat's fore and aft adjustment range ,
and as far away from the airbag as possible before installing
the child restraint.
- Always make sure that nothing prevents the front
passenger's seat from being moved to the rearmost position in
its fore and aft adjustment range .
-Always make sure that the backrest is in the upright posi­
tion .
• Always buckle the child safety seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a collision.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used~
page 189, "Safety belts ",
~ page 199 , "Airbag system " and ~ page 221, "Child Safety".
& WARNING
To reduce the risk of serious injury, make sure that the
PASSENGER AIR BAG OFF light comes on and stays on whenever a
child restraint is installed on the front passenger seat and the
ignition is switched on.
& WARNING (co ntinued )
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on .
• Have the airbag system inspected by your authorized Audi
dealer immediately.
& WARNING
A child in a child restraint installed with the LATCH lower anchor­ ages or with the standard safety belt on the rear seat may play
with unused rear seat safety belts and become entangled resulting in serious personal injury and even death.
• Always buckle unused rear seat safety belts out of reach of chil­
dren in child seats and properly activate the convertible locking
retractor so that the child cannot unreel the safety belt from the
retractor. •
