Child safety
Important information
Introduction
The physical princip les of what happens when
your veh icle is in a cras h apply also to childr en
¢ page 188, What happens to occupants not
wearing safety belts?.
But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater risk of serious injury in crashes than
adu lts.
Because children's bodies are not fu lly devel­
oped, they require restraint systems especially
designed for their size, weight, and body struc­
ture. Many countries and all states of the United
States and provinces of Canada have laws requir­
ing the use of approved child restraint systems
for infants and small children .
In a frontal crash at a speed of 20-35 mph (30-56 km/h) the forces acting on a 13 lbs (6 kg)
infant will be more than 20 times the we ight of
the child . This means the weight of the child
wou ld suddenly be more than 260 lbs ( 120 k g).
Under th ese conditions, only an appropriate child
rest raint properly used can reduce the r isk of se­
rio us injury. Child restraints, like adult safety
be lts, must be used properly to be effective.
Used improperly, they can increase the risk of se­
rious inj ury in an accident.
If you must install a child restraint on the front
passenger seat in exceptional circumstances, be
sure to read and heed the important information
and warn ings
¢ page 195. Infants and other ch il­
dren who are properly restrained in an appropri­
ate child restraint that is for their size and age
can benefit from the protection that supplemen­
tal side airbags provide in some kinds of crashes .

instructions for using child safety seats.
Please
be sure to read and heed all of the important in­
format ion and WARNINGS about child safety,
Advanced Airbags, and the installation of child
restraints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in your veh icle and how they work
when infants and children in ch ild restraints are
on the front passenger seat . Because of the large
amount of impo rtant informat ion, we ca nnot re­
peat it all he re. We urge you to read the detailed
inf ormation in this owner's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans ­
porting children on the front passenger seat.
Please be sure to heed the WARNINGS
-they are
extremely important for your safety and the safe­
ty of your passengers, especially infants and
small children .
.&_ WARNING
All vehicle occupants and especially child re n
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly re­
stra ined child could be injured by striking the
interior or by being ejected from the vehicle
during a sudden maneuver or impact . An un­
restrained or improperly restrained child is al­
so at greater r isk of injury or death through
contact w ith an inflating airbag.
A WARNING
Children on the front seat of any car even with
Advanced Airbags can be seriously injured or
even killed when an airbag inflates. A ch ild in
a rearward-fac ing child safety seat installed
on the front passenger seat will be seriously
in ju red and can be killed if the front airbag in­
flates.
- The inflat ing airbag will hit the child safety
seat or infa nt carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, or
door.

turn on and stay on. Have the system in­
spected immediately by an authorized Audi
dealer or author ized Audi Service Facility .
A WARNING
-Forward-fac ing ch ild seats insta lled on the
front passenge r seat may inte rfere with the
deployment of the a irbag and cause serious
persona l inju ry to the child .
- If except ional circumstances require the use
of a forward-facing child res traint on the
front passenger's seat, the child's safety
and well-being require the following special
precautions to be taken:
- Always make sure that the forward-facing seat has been designed and cert ified by its
manufacture r fo r u se on a front passenger
seat with a front and s ide a irb ag.
- Always carefully follow the manufacturer's
instr uctions provided with the child seat
or i nfan t ca rrier.
- Never p ut the fo rward-facing child re­
s tra int up against o r very near the instru­
men t panel.
- Always move the front passenger seat to
the highest posit ion in the up and down
ad justment range and move it back to the
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-fac ing ch ild restraint.
- Always make sure that the safety be lt up­
pe r anchorage is behind the child restra int
and not next to o r in front of the child re­
stra int so that the safety belt will be prop­
erly positioned.
- Always make sure that nothing prevents
the front passenger's seat from be ing
moved to the rearmost posit ion in its fore
and aft adjustment range .
- Never place objects on the seat (such as a
laptop, CD p laye r, electronic games de­
vice, powe r inverter or seat heater for
child se ats). These m ay influence the ele c-
Ch ild saf ety
trical capacitance measu red by the capac i­
tive passenger detection system and can also fly around in an acc ident and cause
serious personal injury .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, powe r inverter or seat heat ­
er for child seats) on the front passenger
seat if the device is connected to the 12-
vo lt socke t or the cigarette lighter so cket.
- If a seat heate r has been retrofitted or
othe rw ise added to t he front passenger
seat, neve r insta ll any child res traint sys­
tem on this seat.
- Make su re that there a re no wet objects
(s uch as a we t towe l) and no w ater or oth­
er liquids on the front passenger seat
cushion .
- Always make sure tha t the

Child sa fety
Advanced front airbag system and children
Your veh icle is equipped w ith a front "Advanced
A irbag System" in comp liance w it h United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your veh icle has
been certified to meet the " low-risk" require ­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the a irbag inflates. In addit ion, the
system has been certified to comply w ith the
" su ppress io n" req uirements of the Safety S tand­
ard, to tu rn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
E ven tho ugh yo ur vehicle is equipped with an
Ad a
vanced Airbag system, a chi ld should a lways ride
in the seat proper ly restrained for its age and
size. The airbag on the passenger side makes the
front seat a potentially dangerous p lace for a
child to r ide . The front seat is not the safest place
for a child in a forward-facing child safety seat .
It
can be a very dange rous place for a n infant or a
larger child in a rearward-fac ing seat.
The vehicle's Advanced Airbag System has a ca­
pac itive passenger detect ion system in the front
passenger seat cush ion that ca n detect the pres­
ence of a baby or a child in a ch ild restraint sys­
tem on t his seat .
The capac it ive passenger detect ion system regis ­
ters the changes that result in an electr ical field
when a c hild, a child restra int, and a baby blanket
a re on the front passenge r seat. The change in
t he meas ured capacitance due to t he p resence o f
a child, a chi ld restraint, and a baby b lanket on
the front passenger seat is re lated to the chi ld
restraint system resting on the seat . The meas ­
ured capacitance of a ch ild restraint system var-
218
ies depending on the type of system and specific
make and mode l.
The elect rical capac ita nce of the va rious types,
makes, and models of child restra in ts speci fied
by the U.S . National Highway Tra ffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys ­
tem control unit together with the capacitances
typ ica l of infants and a 1-year old child. When a
c hi ld restraint is used on the front passenger
seat w it h a typical 1 year-old infant, t he Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detect ion
system wi th the data stored in the e lec tronic co n­
tro l unit .
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been cert ified by its manu ­
factu rer for use w ith an airbag . If in exceptional
c ir cumstances you m ust use it on the front pas­
senger seat, ca refully read all of the information
o n chi ld safety and Advanced Airbags and heed
a ll of th e app licab le WARNINGS . Make certain
that the chi ld and chi ld restraint are correctly
recognized by the capacitive passenger detection
system in the front passenger seat, that the front passenger a irbag is turned off, and that the air­
bag status is always correct ly signa led by the
PASSENGER AIR BAG OFF ~; light.
Many types and models of child restra ints have
been available over the years, new models are in­
troduced regularly incorporating new and im­
proved designs and older models are taken out of
production . Ch ild rest rai nts are not standa rdized .
Child res tra ints of the same type typically have
d iffe rent weights and sizes and diffe re nt "foot ­
pr ints", the size and shape o f th e bo ttom of the
ch ild restraint that sits on the seat, w hen they
are installed on a vehicle seat . These differences
make it virtua lly impossib le to certify comp liance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been
sold in the past or will be sold over the course of
the useful life of your veh icle .

Important safety instructions for using
child safety seats
Correct use of child safety seats substantially re­
duces the risk of injury in an accident!
As the driver, you are responsib le for the safety
of everybody in the vehicle, especia lly children:
.. Always use the right child safety seat for each
child and always use it properly ¢
page 221.
.. Always carefully follow the chi ld safety seat
manufacturer's instructions on how to route
the safety belt properly through the ch ild safe­
ty seat.
.. When us ing the veh icle safety belt to install a
child safety seat, you must first activate the
convertib le loc king ret racto r on the safety belt
to p revent the ch ild safety seat from moving
q page 225 . ..,

Child sa fety
~ Push the child sa fety seat down with your fu ll
weight to get the safety be lt really tight so that
the seat cannot move forward and s ideways
more than 1 in (2.5 cm).
A lways remember: Even though your vehicle is
equipped with an Advanced Airbag system, a
child should always ride in the seat properly re­
stra ined for its age and size.
A WARNING
Not using a ch ild safety seat, using the wrong
child safety seat or improperly install ing a
child restra int increases the r isk of se rious
personal inju ry and death.
- All veh icle occupants and especially children
must be rest rained p roperly whenever riding
in a vehicle. An unrestrained or imprope rly
restra ined child could be injured by s tri king
the interior or by being ejected from the ve­
hicle d uring a sudden maneuver or impact .
An unrestrained or improperly restrained
child is also at greater risk of injury or death
through contact with an inflating airbag.
-Commercially available chi ld safety seats
are required to comply with U.S. Federa l
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213).
-When b uying a ch ild rest raint, se lect one
that fits your child and the vehicle .
-Only use child rest raint systems that fully
con tact the flat portion o f the seat cush­
ion. The child restraint must not tip or
lean to either side . Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide adequate contact with the seat.
-Always heed a ll legal requirements per­
taining to the installat ion and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you a re us ing .
-Never let more than one child occupy a child
safety seat.
-Never let babies or older children ride in a
vehicle while sitting on the lap of another passenge r.
220
-Holding a child in your arms is never a sub­
stitute fo r a child restraint system.
-The strongest person cou ld not hold the
ch ild with the forces that exist in an acc i­
dent. The child will strike the interior of
the veh icle and can also be struck by the
passenger.
-The child and the passenger can also in­
ju re each other 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 k illed when the passenger a irbag in­
flates -even with an Advanced Airbag Sys­
tem.
-The inflating airbag will h it the ch ild safety
seat o r infant ca rr ier with great force and
will sm ash the child s afety seat and child
aga inst the ba ckres t, center armres t, door
or roof.
-I f exceptional ci rcums tances requi re the use
of a forward-f acing child restrain t on the
front passenger's seat, the chi ld's safety
and well-being require that the following
special precautions be taken:
-Make su re the forwa rd-facing seat has
been designed and ce rtified by its manu­
fa ctu rer for use on a front se at with a pas­
senger front and side ai rb ag.
-Always ca refully follow the man ufa ctu rer 's
i nst ru ct ions prov ided with t he ch ild sa fety
seat or carrier.
-Always move the fron t passenger seat into
the rearmost posit ion of the passenger
seat's fo re and aft adjustment range, and
as far away from the airbag as possib le be­
fore 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 s ure t hat the backrest is in
the up right pos ition.
-Never place or use any elect rical device
