in a side collision. The side curtain ai rbag in ­
f lates in side impacts and on ly when the vehi­
cle acce lerat ion reg istered by the contro l unit
is high enough. If th is rate is be low the refer ­
ence value programmed into the control un it,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­ sult of the collision . It is not possible to de­
f ine an a irbag tr igger ing range that will cover
every possible angle of impac t, since the ci r­
cumstances wi ll vary conside rably between
one co llision and another . Important factors
include, for examp le, the nat ure ( hard o r soft)
of the impacting object, the ang le of impact,
veh icle speed, etc.

Aside from the ir normal safety function , safe ­
ty belts work to he lp keep the driver or front
passenger in posit ion in the event of a co lli­
sion so that the side curtain airbags can pro­
vide protection.
The airbag system is not a s ubstitute for yo ur
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety belt and wear ing it prope rly. Thi s
i s another reason why you sho uld always wear
your safety bel ts, not just beca use the law re­
q uir es you to do so

notes.
It
is important to rememb er that while the
side curta in a irbag sys tem is designed to he lp
r educe the like lihood of se rious injur ies, other
in ju ries, for example, swell ing, bruising, and
minor abrasions can a lso be associated with
these airbags upon deployment. Remember
too, these a irbags w ill dep loy on ly once and
only in certain kinds of accide nts - your safety
be lts are a lways there to offer protection .

How side curtain airbags work
Side curtain airbags ca n work together with
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
are properly restrained.

144 Child Safety
-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
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 position and have the air­
bag system inspected immediately 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 in­
structions 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 airbag as possible before installing
the child restraint. The backrest 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.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
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.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3- and 6-year old children on
the passenger 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 airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system , all children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger side makes the front seat a potentially dangerous place for a child to ride . The front
seat is not the safest place for a child in a for­
ward-facing child safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat .
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight-sensing mat in the seat cush ­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight -sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the .,..

seat. The weight of a child restraint and its
"footprint" vary for different kinds of child re­
straints and for the different models of the
same kind of child restraint offered by child restra int manufacturers.
The weight ranges for the individual types, makes and mode ls of ch ild restra ints that the
NHTSA has specified in the Safety Standard
together with the we ight ranges of typical in­
fants and typical 1 year -old child have been
stored in the control unit of the Advanced A ir­
bag System . When a chi ld restraint is being
used on the front passenge r seat with a typi­
cal 1 year -old ch ild, the A dvanced Airbag Sys­
tem compares the we ight measured by the
weight sensing mat with the information stor­
ed in the electronic control unit.
The electron ic contro l unit al so registers the
tension on the front passenger safety be lt.
The tension on the safety be lt for the front
passenger seat will be different for an adult
who is properly using the safety belt as com­
pared to the tension on the be lt when it is
used to attach a child restraint to the seat.
T he sensor below the latch for the safety belt
for the front seat passenger measures the
tension on the belt . T he input from this sen­
sor is t hen used w ith the we ight to "decide",
whether there is a ch ild restraint with a typ ica l
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off .
Child restraints and Advanced Airbags
Regard less 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 manu­
facturer for use with an airbag . Always be sure
that the chi ld restraint is p roperly instal led at
one of the rear seat ing pos itions . If in excep­
tional ci rcumstances you must use it on the
front passenger seat, carefu lly read all of the
information on child safety and Advanced Air­
bags and heed a ll of the app licable WARN­
INGS. Make certain that the child restraint is
correctly recognized by the weight-sensing
Child Sa fet y 145
mat inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag status is always correct ly signaled
by the
PAS SENGE R AIR BAG OFF light.
Many types and models of child restraints
have been available over t he years, new mod­
els are introduced regu larly incorporating new
and improved des igns and o lder models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typ ically have d ifferent weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restrai nt that sits
o n the seat, when they a re insta lled on a veh i­
cle seat. These diffe rences make it v irtually
impossible to certify compliance with the re­
quirements for advanced airbags with each
and every ch ild restraint that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For this reason, the United States National
Highway Traffic Safety Adm inistrat ion has
published a list of spec ific type, makes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag
System in your veh icle with the suppression
requirements of Federal Motor Vehicle Safety
Standa rd 208. These chi ld restraints are :

A WARNING
If exceptional circumstances require the
use of a fo rward-facing child restraint on
the front passenge r's sea t, the child's safe­
ty and well-being require t hat the follow­
i ng spe cial preca utions be ta ken:
- Make sure t he forward-facing seat has

- Always move the front passenger seat in­
to the re armos t posi tion of the passen­
ge r seat's fo re and aft adjustment range,
an d as far away from the airbag as possi­
b le before installing the ch ild restraint.
- Always make sure that no thing prevents

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and
80 lbs. (18 kg and 36 kg) who are less than 4
ft. 9 in. (57 inches/1 .45 meters) tall.
Fig. 142 Rear seat : child prope rly restrained in a boos­
ter seat
The vehicle's safety belts alone will not fit
most children until they are at least 4
ft. 9 in.
(57 inches/1.45 meters) tall and weigh about
80 lbs. (36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass prop­
erly over the stronger parts of their bodies
and the safety belt can help protect them in a
crash.
.,. Do not use the convertible locking retractor
when using the vehicle's safety belt to re­
strain a child on a booster seat .
.. Always position the shou lder portion of the
safety belt midway over the child's shoulder.
If you must transport an older child in a
booster seat on the front passenger seat,
you can use the safety belt he ight adjust­
ment to help adjust the shoulder portion
properly .
.. Always make sure tha t the shoulder port ion
of the safety belt never rests against or
across the child's neck .
.. Always make sure that the child can proper­
ly wear the lap portion of the belt low across
the thighs or pelvis and
never over the
stomac h or abdomen.
Children up to at least 8 years old (over 40 lbs
or 18 kg) are best protected in chi ld safety
seats designed for their age and weight. Ex­ pe rts say that the ske letal structure, particu­
larly the pelvis, of these ch ildren is not fully
Child Safety 15 1
developed, and they must not use the vehicle
safety belts without a suitable chi ld restraint.
It is usually best to put these child ren in ap­
propriate booster seats. Be sure the booster
seat meets all applicable safety standa rds.
Booster seats raise the seat ing pos ition of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass
ac ross the child's body in the right p laces. The
routing of the belt over the child's body is very
important for the child's protect ion, whether
or not a booster seat is used. Children age 12
and under must always r ide in the rear seat.
Children who are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall can generally use the
vehicle 's three point lap and shoulder belts.
Never use the lap belt portion of the vehicle's
safety belt alo ne to restrain any child, regard ­
less of how big th e ch ild is. Always remember
that children do not have the pronounced pel­
vic structure required for the pro pe r function
of lap belt portion of the vehicle's three point
lap and shoulde r belts. The child's safety ab­
so lutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as
possible around the pelvis. Never let the lap
belt portion of the safety belt pass over the
child's stomach or abdomen .
In a crash, airbags must inflate within a blink
of an eye and with considerable force. In order
to do its job, the a irbag needs room to inflate
so that it will be there to protect the occupant
as the occupant moves forward into the a ir ­
bag.
A veh icle occupant who is out of position and
too close to the a irbag gets in the way of an
inflating airbag. When an occupant is too
close, he or she will be st ruck v iolently and
will receive serious or possibly even fatal in­
jury.
In order for the airbag to offer protection, it is
im portant that all veh icle occupants, especial-
ly any children, who must be in the front seat
because of exceptiona l circumstances, be
properly restrained and as far away from the
airbag as possible. By keeping room between ..,_
