Aside from the ir norma l safety func tion, sa fety be lts work to help
keep the driver or front passenger in position in the event of a colli ­
s ion so that the s ide curtain a irbags can provide protection.
T he airbag system is not a substitute for your safety belt. Rather, it
is part of the overall occupant restraint system in your veh icle .
A lways remember that the airbag system can only help to protect
you if you are wea ring your safety belt and wearing it proper ly . This
is another reason why you should a lways wear your safety belts, not
just because the law requires you to do so=>
page 137, "General
notes".
I t is important to remember that while the side curtain airbag
system is des igned to help reduce the likelihood of serious injuries,
other injuries, for examp le, swelling, bruising, and minor abrasions
can a lso be associated with these airbags upon de ployment .
Remember too, these airbags will dep loy only once and only in
certa in kinds of accidents -your safety be lts a re a lways there to
offer protection.
The side curtain airbag system basically consists of :
• The electronic control module and externa l side impact sensors
• The side curtain airbags above the fron t and rear s ide windows
• T he airbag indicator light in the instrument panel
The airbag system is moni tore d electronically to make c ertain it is
functioning properly at a ll times . Each time you turn on the ignition,
the ai rbag system indicator light w ill come on for a few seco nds
(self diagnostics).
The side curtain airbag is not activated :
• if the ignition is turned off,
• in side coll isions when the acce leration measured by the senso r
is too low,

& WARNING
• Safety belt s and the airbag sy stem will only prov ide protection
when oc cupant s are in the proper seating position

When the system is triggered, the side curtain airbag is filled with
p ropel lan t gas and b rea ks th roug h a sea m above the fron t and rear
side windows identified by the A IR BAG labe l. In order to help
provide th is additi ona l protec tion, the side curtain ai rbag must
inflate within the b link of an eye at very high speed and with great
force . The side cu rtain ai rbag could inju re you if yo ur seating posi ­
t ion is not p roper or upright or if items are located i n the a rea w here
the supplementa l side curtain airbag inflates . This applies espe ­
cia lly to child re n :::::,

Although they are not a soft pi llow, side curtain airbags can
"cus hion" the im pac t and in this way they can hel p to reduce the risk
of injury to the head and the upper part of the body .
A fine dust may develop when the airbag deploys . This is q uite
n orma l and does no t mean t he re is a fi re i n th e ve hicle .•

Modifications" .
• Do not sw ivel the sun visors to the s ide if you have any objects
clipped onto them (for example pensl.
If the airbag should deploy ,
you could be injured by these objects .
• Use the built -in coat hooks only for lightweight clothing . Never
leave any heavy or sharp-edged objects in the pockets that may
interfere with airbag deployment and can cause personal injury in
an accident .
• Never u se hangers to hang clothing from the hooks.
• Only use fa ctory-installed sun shades or , in the case of shades
installed after the vehicle leaves the factory , only Audi roll -up
suns creens m ay be used => page 305 , "Additional a ccessories and
parts replacement ".
• Always sit in proper seating position and wear safety belts
while traveling so that the side curtain airbags can help provide protect ion .
• The airbag system can only be triggered once.
If the airbag has
been triggered, the system must be replaced by an author ized
Audi dealer or qualified workshop.
• Always have work involving the side curtain airbag system ,
removal and installation of the airbag components, or other
repairs performed by a qualified workshop . Otherwise the airbag
system may not work correctly.
• Never attempt to modify any components of the airbag system
in anyway. •

Child Safety
Important things to know
Introduction
The rear seat is generally the safes t place in a collision.
The p hysica l pr inciples of what happens when you r veh ic le is in a
crash apply also to children=> page 139, "What happens to occu ­
p a nts not wearing safety bel ts?" . Bu t un like adults and teenagers,
their musc les and bones are not fu lly developed. In many respects
children a re a t greater ris k of serious inj ury in cras hes than a dults .
B ecause chi ldren 's bodies a re no t fully deve loped, they require
restraint systems especial ly designed for their size, weight, and
body structu re. Ma ny countries and al l sta tes of the U nited States
and provinces of Canada have laws requiring the use of approved
chil d restraint sys te m s for infa nts and smal l children .
I n a frontal crash at a speed of 20 -35 mph (30 -56 km/h) the forces
ac ting on a 13-pou nd (6 kg) infant wi ll be mo re than 20 times the
weight of the child. This means the weight of the child would
suddenly be more than 260 pounds ( 120 kg). Under these condi ­
t ions, only an appropriate child restraint proper ly used can reduce
the risk of serious in jury. Child restraints, like adult safety belts,
must be use d properly t o be eff ective. Use d impro perly, they can
increase the risk of serious injury in an accident .
Co nsul t the c hild safety seat man ufacture r's ins truc tions to be su re
the seat is right for your child's size=> page 172, "Important safety
instructions for using child safety seats" . Please be sure to read and
heed a ll of the important information and WARNI NGS about child
safety, Advanced Airbags, and the insta llation of child restraints in
this chapter.
T here is a lot you need to know about the Advanced Airbags in your
veh ic le and how they work whe n inf an ts and ch ild ren in c hild
restraints are on the front passenger seat. Because of the large
Controls and equip­ ment Safety first Vehicle operation amoun
t of important informat ion, we cannot repeat it all here. We
urge you to read the detai led information in this owner's manua l
about a irbags and the Advanced Airbag Sys tem in your ve hic le and
the very important information about transporting children on the
fr ont passenger sea t. Please b e sure to hee d th e WAR NINGS -th ey
are extreme ly important for your safety and the safety of your
p asse ngers, es pecia lly inf ant s and s mall ch ildren .
& WARNING
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating position . Always
restrain any child age 12 and under in the rear.
• All vehicle o ccupants and especially children must be
restrained properly whenever riding in a vehicle . An unrestrained
or improperly restrained child could be injured by striking the inte­
rior or by being ejected from the vehicle during a sudden
maneuver o r impact . An unrestrained or improperly restrained
c hild is also at greater risk of injury or death through conta ct with
an inflating a irbag .
• A suitable child restraint properly installed and used at one of
the rear seating positions provides the highest degree of protec­
tion for infants and small children in most accident situations .
& WARNING
Children on the front seat of any car even with Advanced Airb ags
c an be seriously injured or even killed when an airbag inflates . A
child in a rearward -fa cing child safety seat installed on the front
pas senger seat will be seriously injured and can be killed if the
front airbag inflates.
• The inflating airbag will hit the ch ild safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest , center arm rest , or door. •

-Child Safety ------=---------------------------------
& WARNING (continued )
• Always install rear-facing child safety seats on the rear seat .
• If you must install a rearw ard fa cing child safety seat on the
front passenger seat in 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 posit ion and have the airbag system inspected immedi ­
ately by your authorized Audi dealer .
& WARNING
If, in exceptional circumstances, you must install a forward -facing
child 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.
• Always follow the manufacturer's instructions provided with
the child safety seat or carrier.
• 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 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
Y our vehicle is equipped with an " Advanced Airbag Syste m" in
co mplia n ce wi th Unit ed States F edera l Moto r Veh icle Saf ety S tan­
dard ( FMVSS) 208 as appl icable at the time your vehicle was manu ­
f actu re d . T
he Advanced Airbag system in your vehicle has been certified to
m eet the " lo w -ris k" req uiremen ts for 3 and 6 year -ol d c hildren on
the passenger side a nd smal l adults on the driver side . The low risk
de ploymen t criteria a re i ntended to reduce the risk of i nju ry t hroug h
interaction with the airbag that can occur, for example, by bei ng too
close to the s tee rin g w heel and instrume nt panel whe n the ai rbag
i n fl ates. In add it ion, t he sys tem has been cer tified to co mply wi th
the "suppre ssion" req uirement s of the Safety Standa rd, to turn off
the front a irbag f or infants up to 12 month s who ar e restrai ned on
the front passenger seat in child restraints that are listed in the
S tan dard.
E ven though your vehicle is equipped with an Advanced Airbag
sy stem , a ll ch ildr en, especia lly those 12 yea rs and yo unge r, should
a lways ride i n the back seat prop erly re stra ined for t heir a ge and

restraint offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of
child restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typ ical 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 child, the Advanced Airbag
System compares the weight measured by the weight sensing mat
with the information stored in the electronic control unit.
The electronic control unit also 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, make sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been certified by its manufacturer for use with
an airbag. Always be sure that the chi ld restraint is properly
installed at one of the rear seating positions. If in exceptiona l
circumstances you must use it on the front passenger seat, carefully
read all of the information on child safety and Advanced Airbags
and heed a ll of the applicable WARNINGS. Make certain that the
child restraint 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
th e
PASSENGER AIR BAG OFF light .
Controls and equip­
ment Safety first Vehicle operation
Many
types and models of child restraints have been available over
the years, new mode ls are introduced regularly incorporating new
and improved designs and older mode ls are taken out of produc­
tion. Child restraints are not standardized . Child restraints of the
same type typically have different weights and sizes and different
'footprints,' the size and shape of the bottom of the chi ld restraint
that sits on the seat, when they are installed on a vehicle sea t. These
differences make it virtual ly impossible to certify comp liance with
the requirements for advanced airbags with each and every child
restraint that has ever been sold in the past or will be sold over the
course of the usefu l life of your vehic le.
For this reason, the United States National Highway Traffic Safety
Administration has pub lished a list of specific type, makes and
models of child restraints that must be used to certify compliance
of the Advanced Airbag System in your vehicle with the suppression
requirements of Federal Motor Vehicle Safety Standard 208. These
child restraints are:

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 every ­
body in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly ::::>
page 174.
- 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 convertible locking
retractor on the safety belt to prevent the child safety
seat from moving ::::>
page 179.
- Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety
seat to the front passenger seat, make sure that it is not
so tight that it causes the weight-sensing mat to
measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size. _,,

Child Safety -
--------------------''---
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death .
• All vehicle occupants and especially children must always be
restrained properly whenever riding in a vehicle .
- An unrestrained or improperly restrained child can be injured or killed by being thrown against the inside of the vehicle or by
being ejected from it during a sudden maneuver or impact.
- An unrestrained or improperly restrained child is at much
greater risk of injury or death by being struck by an inflating
airbag.
• Commercially available child safety seats are required to
comply with U .S . Federal Motor Vehicle Safety Standard (FMVSS l
213 (in Canada CMVSS 213).
-When buying a child restraint , select one that fits your child
and the vehicle .
- Only use child restraint systems that fully contact the flat
portion of the seat cushion. The child restraint must not tip or
lean to either side . Audi does not recommend using child safety
seats that rest on legs or tube -like frames . They do not provide
adequate contact with the seat .
- Always heed all legal requirements pertaining to the installa ­
tion and use of child safety seats and carefully follow the
instructions provided by the manufacturer of the seat you are
us ing .
• Never allow children under 57 inches {1 .5 meters) to wear a
normal safety belt . They must always be restrained by a proper
child restraint system . Otherwise , they could sustain injuries to
the abdomen and neck areas dur ing sudden braking maneuvers or
accidents.
• Never let more than one child occupy a child safety seat .
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued )
• Never let babies or older children ride in a vehicle while sitting
on the lap of another passenger .
- Holding a child in your arms is never a substitute for a child
restraint system .
- The strongest person could not hold the child with the forces
that exist in an ac cident. The child will strike the interior of the
vehicle and can also be struck by the passenger .
- The child and the passenger can also injure each another in
an accident.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat . A child will be seriously injured and can
be killed when the passenger airbag inflates - even with an
Advanced Airbag System .
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest , center arm rest , door or roof .
• Always install rear-facing child safety seats or infant carriers on
the rear seat .
• Forward -facing child safety seats installed on the front
passenger 's seat can interfere with the airbag when it inflates and
cause serious injury to the child. Always install forward -facing
child safety seats on the rear seat .
• 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
c ertified 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.

& WARNING (continued)
-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 137, "Safety belts",
=> page 147, "Airbag system" and=> page 169, "Child Safety".

Child safety seats
Infant seats
Babies and infants up to about one year old and 22 lbs or
10 kg need special rearward-facing child restraints that
support the back, neck and head in a crash.
Fig . 151 Rearward­
facing infant seat,
properly installed on
the rear seat
-When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking
retractor on the safety belt to prevent the child safety
seat from moving~
page 179 or install the seat using
the LATCH attachments.
- Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
Infants up to about one year (22 lbs. or 10 kg) are best protected in
special infant carriers and child safety seats designed for their age
group. Many experts believe that infants and small children should
ride only in special restraints in which the child faces the back of the
vehicle. These infant seats support the baby's back, neck and head
in a crash . These child safety seats must never be used in the front
seat because of the risk of serious injury or death should the airbag
deploy in a crash=> fig. 151. ..
