Automatic safety belt retractors
Every safety belt is equipped with an automat­
ic belt retractor on the shoulder belt. This fea­
ture locks the belt when the belt is pulled out
fast, during hard braking and in an accident.
T he belt may also lock when you drive up or
down a steep hill or through a sharp curve.
During normal driving the belt lets you move
freely .
Safety belt pretensioners
The safety belts on the front seats are equip­
ped with a belt pretensioner that helps to
tighten the safety belt and remove slack when
the pretensioner is activated. The function of
the pretensioner is monitored by a warning light
c:> page 15 .
Switchable locking feature
Every safety belt except the one on the driver
seat is equipped with a switchable locking fea­
ture that
must be used when the safety belt is
used to attach a child seat . Be sure to read the
important information about this feature
c:> page 140.
_& WARNING
Improperly positioned safety belts can

a nd chi ld safety seats designed for their age
group. Many experts believe that i nfants a nd
small children should ride only in spec ial re­
strai nts in which the ch ild faces the back of
the vehicle . These infant seats support the ba­

fig . 113 .
The airbag on the passenger side makes the
front seat a po tentially dangerous place for a
chi ld to r ide. The front seat is not the safest
p lace for a child in a forward-facing child seat.
It is a very dangerous p lace for an infant or a
larger child in a rearward-facing seat .
A WARNING
Not using a child safety seat, using the
wrong ch ild safety seat or improperly in­
stall ing a child restraint inc reases the risk
of serious persona l injury and d eath in a
c rash .
- Never install rear-fac ing ch ild safety
seats or infant carriers on the front pas­ senger seat -even wi th an Advanced Air­
bag System. A child w ill be seri ously in­
jured an d can be k illed when the inflat­

A toddler or child is usually too large for an in ­
fant restraint if it is more than one year o ld
and weighs more than 20 lbs . (9 kg) .
Todd le rs and c hildren who are older than one
year up to abo ut 4 years o ld and weigh more
than 20 lbs. (9 kg) up to 40 lbs . (18 kg) must
a lways be properly restrained in a chi ld safety
seat certified for their size and weight
r::!> fig. 114 and r:::>fig. 115.
The airbag on the passenge r side makes the
front seat a potentially dangerous place for a
chi ld to ride. The front seat is not the safest
p lace for a child in a forward-facing child safe­
ty seat.
It is a very dangerous place for an in­
fant or a larger child in a rearward-fac ing seat.
A WARNING
Not using a ch ild safety seat , using the
w rong chi ld safety seat or improperly in­
stalling a child restraint increases the risk
of serious personal injury and death in a
co llision or other emergency s ituation.
- Children on the front seat of any car,
even with Advanced A irbags, can be seri­
o usly injured or even killed when an air­

A WARNING
If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safe ­
ty and well-being require that the follow­ ing spec ial precautions be taken:
- Make sure the forward-facing seat has
been designed and cert ified by its manu­
facturer for use on a front seat with a passenger front and side airbag .
- Always follow t he manufacturer's in ­
structions p rov ided with the ch ild safety
seat o r infant ca rr ier .
- Always move the front passenger seat in­
to the rearmost position of the passen­
ge r seat's fo re and aft adjustment range,
a nd as far away from the ai rbag as possi­
b le before installing the ch ild restraint.
- Always ma ke sure that no thing prevents
the front passenger 's seat from being
moved to the rearmost position in its
fore and aft adj ustment range.
- Always ma ke sure the backrest is in an
up right position .
- Ma ke sure that the

Booster seats and safety belts
Properly used booster seats con help protect
children weighing between about 40 lbs. and
80 lbs . (18 kg and 36 kg) who ore less than 4
ft. 9 in. (57 inchesll .45 meters) toll.
Fi g. 11 6 Rear seat: child properly restra ined in a boos ­
te r seat
Booster seats raise these children up so that
the safety belt will pass properly 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
stra in a child on a booster seat .
> The shoulder belt must lie as close to the
center of the child's collar bone as poss ible
and must lie and snug on the upper body. It
must never lie across the th roat or neck . The
l ap belt must lie across the pe lvis and never
across the stomac h or abdomen. Make sure
the belt lies f lat and snug . Pull on the be lt
to t ighten if necessary.
> Secure unused safety belts on the rear seat
c:> poge 135.
Children up to at least 8 years old (over 40
lbs. or 18 kg) are best protected in child safe­
ty seats des igned for their age and weight. Ex­
perts say that the skeletal structure, particu­
larly the pelvis, of these children is not fully
developed, and they must not use the vehicle
safety belts without a suitable c hild restraint.
It is usually best to put these chi ldren in ap­
propr iate booster seats. Be sure the booster
seat meets all applicable safety standards.
Booster seats ra ise the seating posit ion of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the ch ild's body in the r ight p laces . The
routing of the belt over the ch ild 's body is very
important for the child's protect ion, whether
o r not a booster seat is used. Chi ldren age 12
and under must always r ide in the rea r seat.
Children who are at least 4
ft. 9 in. (57 in­
ches/1.45 mete rs) tall can gene ra lly us e the
vehicle's three point lap and shoulder belts.
Never use the lap belt port io n of the vehicle 's
safety belt alone to restrain any chi ld, regard­
less of how big the chi ld is . Always remember
that children do not have the pronounced pel­
vic structure required for the proper funct ion
of lap belt portion of the vehicle's three point
lap and shou lder belts. T he child's safety ab­
solutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as
poss ible a round the pe lvis. Neve r let the lap
belt port ion of the safety belt pass over the
c hi ld 's stomach or abdomen.
In a crash, a irbags must inflate within a blink
of an eye and with considerable force. In o rder
to do its job, the a irbag needs room to inflate
so that it will be the re to p rotect the occ upan t
as the occupant moves forward into the air­
bag.
A vehicle oc cupant who is out of posit ion and
too close to the a irbag gets in the way of an
inflating airbag. When an occ upant is too
close, he or s he will be struck violently and
will receive serious or possibly even fatal in-
jury. .,.

140 Child Saf ety
must never -under any circumstances -
be less than 1 inch (2.5 cm.) when the
passengers sits fully upright .
- Always make sure that the rear seat pas­
sengers cannot be struck when the rear
lid is closed.
Booster seats on the front seat
Children aged about 7 years and older and
weigh ing more than 55 lbs (25 kg) who are
between 4'3" (1.3 m) and 4 '11 " (1.5 m) tall
may in exceptiona l circumstances ride on the
front passenger 's seat. Children less than 4'
9" (1.4 m) tall must sit on a certified booster
seat and properly wear the vehicle's three­ point lap and shou lder safety belt.
A lways securely latch the passenger seat at
the very rear of its fore and aft adjustment range . The backrest must be adjusted to an
upright position .
.&_ WARNING
If you must install a booster seat child re­
straint on the front passenger seat :
- Make sure the booster seat has been de­
signed and certified by its manufacturer
for use on a front seat with a passenger
front and s ide a irbag.
- Always follow the manufacturer's in­
struct ions provided with the booster
seat .
- Always move the passenger seat to the
very rear of its fore and aft adjustment
range, as far away from the airbag as
poss ible .
- Always make sure that the passenger
seat is securely latched in place before
install ing the booster seat . The backrest
must be adjusted to an upright position.
-If the passenge r seat cannot be securely
latched in the very rear of its fore and aft
adjustment range, then the passenger
front a irbag must be turned off with the
ON / OFF switch.
Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger can be locked with the convertible
locking retractor to properly secure child
safe ty sea ts.
The safety belts emergency locking retractors
for the rear s eats safety belts and for the
front passenger's seat safety belt have a con­
ver tible locking retractor for child restraints.
The safety belt must be locked so that belt
webbing cannot unreel. The retractor can be
activated to lock the safety belt and prevent
the safety be lt webbing from loosening up
during norma l dr iving . A chi ld safety seat can
only be prope rly installed when the safety be lt
is locked so that the chi ld and child safety
seat wi ll stay in place .
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and young­
er, shou ld always ride in the back seat proper­
l y restrained for their age and size.
.&_ WARNING
Improperly installed chi ld safety seats in­
crease the risk of serious personal injury
and death in a collision .
- Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt re ­
tractor cannot hold the child safety seat
in place dur ing normal driving o r in a
crash.
- Always buckle the child safety seat firmly
in place even if a ch ild is not sitting in it.
A loose child safety seat can fly around
during a sudden stop or in a collision
- If the backrest is not securely latched,
the child and the child restraint will be
thrown forward together with the back-
rest and will strike parts of the vehicle ..,_

142 Child Safety
-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, door or
roof.
- Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances.
-A tight tether strap on a rearward-facing child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air­
bag System. The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­
ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child .
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched on .
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your Audi
dealer.
Activating the convertible locking retractor
