Infant seats
Babies and infants up to about one year old
and 20 lbs. or 9 kg need special rearward-fac ­
ing child restraints that support the back,
neck and head in a crash.

Infants up to about one year (20 lbs. or 9 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 spec ial re­
straints in which the ch ild faces the back of
the vehicle . These infant seats support the ba­
by's back, neck and head in a crash ¢
fig. 174.
The airbag on the passenger side makes the
fro nt seat a potentially dangerous place for a
child to r ide . The front seat is not the safest
p lace for a child in a forwa rd-facing child seat.
I t 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 child safety seat o r improperly in ­
stalling a ch ild restra int increases the risk
of ser ious personal in ju ry and death in a
crash.
- Never install rear-facing child safety
seats or infant ca rr ie rs o n the front pas­
senger sea t -even with an Advanced Air­
bag Sys tem. A c hild will be ser iously in­
jured and can be killed whe n the inflat ­
ing ai rbag hits the child safety seat or in­
fant carrier with great force and smashes the child safety seat and child against
the backrest, center armrest, door or
roof ¢

- Always install rear-facing ch ild safety
seats or infant ca rr ie rs on the rear seat .
- Never install a rear-fac ing ch ild restra int
in th e forward-fac ing direct ion. Such re­
straints are designed for the special needs of infants and very small ch ild ren
an d cannot protect them prope rly if the
seat is forward- facing.

Child Safety 185
Toddlers and children who are older than one
year up to about 4 years old and weigh more
than 20 lbs. (9 kg) up to 40 lbs. (18 kg) must always be properly restrained in a child safety
seat cert ified for their si ze and weight

The airbag on the passenger side makes the
front seat a potentially dangerous place for a
child to ride . The front sea t is not the sa fest
place for a child in a forward -facing child safe ­
ty seat .
It is a very dangerous place for a n in­
fant or a large r ch ild in a rearward-facing seat .
.&_ WARNING
Not using a child safety seat, using the
wrong child s afety seat o r imprope rly in­
stalling a chi ld restraint increases the risk
of serious personal injury and death in a
collision or other emergency situation .
- Ch ildren on the front seat o f any car,
even with Advanced Airbags, can be se ri­
ously injured or
even killed when an air­
bag inflates. A chi ld in a rearward-facing
child safety seat installed o n the front
passenger seat will be serious ly injured
and can be k illed if the front airbag in­
flates -
even with an Advanced Airbag
System .
- The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force a nd will smash the child safety seat
and child against the ba ckrest, center
a rmrest, doo r or roof.
- Always install rear-fac ing ch ild safety
seats o n the rear seat .
- If you must install a rearwa rd fac ing
child safety seat on the fro nt passenger
seat because of exceptiona l circumstan­
ces and t he

to the backrest on the vehicle seat. Ad­
just or remove the rear seat head restraint if it is difficult to install the
child seat with the head restraint in place
<=> page 65 . Install the head restraint
again immediately once the child seat is
removed. Driving without head restraints
or with head restraints that are not prop­
erly adjusted increases the risk of serious
or fatal neck injury dramatically.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used
<=> page 149, Safety
belts,¢ page 157, Airbag system
and
i=> page 178, Important things to know.
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 special precautions be taken:
- Make sure the forward-facing seat has been designed and certified by its manu­
facturer 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 infant carrier.
- Always move the front passenger seat in­
to the rearmost position of the passen­
ger seat's fore and aft adjustment range,
and as far away from the airbag as possi­
ble 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 the backrest is in an
upright position.
- 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 light does not stay on, perform the
checks
¢ page 168, Monitoring the Ad­
vanced Airbag System.
-
- Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
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. 177 Rear seat: ch ild properly rest rai ned in a boos­
te r 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 wil l pass prop­
erly over the stronger parts of their bodies
and the safety belt can he lp 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.
"'The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body. It must never lie across the throat or
neck . The lap belt must lie across the pelvis
and never across the stomach or abdomen .
Make sure the belt lies flat and snug . Pull on
the belt to tighten if necessary .
"'If you must transport an older child in a
booster seat on the front passenger seat,
you can use the safety belt height adjust­
ment to help adjust the shoulder portion
properly.

~ Secure unused safety belts on the rear seat
¢page 183.
Children up to at least 8 years old (over 40
lbs. or 18 kg) are best protected in child safe­
ty seats designed 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 child restraint .
It is usually best to put these children in ap­
propriate booster seats. Be sure the booster
seat meets all applicable safety standards .
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the child 's body in the right places. The
routing of the belt over the child's body is very
important for the child's protection, whether
or not a booster seat is used . Children age 12
and under must always ride 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 alone to restrain any child, regard­
less of how big the child is. Always remember
that children do not have the pronounced pel­
vic structure required for the proper function
of lap belt portion of the vehicle's three point
lap and shoulder belts. The child's safety ab­
solutely 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 airbag needs room to inflate
so that it will be there to protect the occupant
as the occupant moves forward into the air­ bag.
A vehicle occupant who is out of position and
too close to the airbag gets in the way of an inflating airbag. When an occupant is too
close, he or she will be struck violently and
Child Safety 187
will receive serious or possibly even fatal in­
jury.
In order for the airbag to offer protection, it is
important that all vehicle occupants, especial­
ly any children, who must be in the front seat
because of exceptional circumstances, be
properly restrained and as far away from the
airbag as possible . By keeping room between
the child's body and the front of the passen­
ger compartment, the airbag can inflate com ­
pletely and provide supplemental protection
in certain frontal collisions .
_&. WARNING
Not using a booster seat, using the boos­
ter seat improperly, incorrectly installing a booster seat or using the vehicle safety
belt improperly increases the risk of seri­
ous personal injury and death in a collision
or other emergency situation. To help re­
duce the risk of serious personal injury
and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possi­
ble and must lie flat and snug on the up­
per body . It must never lie across the
throat or neck . The lap belt must lie
across the pelvis and never across the
stomach or abdomen. Make sure the belt lies flat and snug. Pull on the belt to
tighten if necessary.
- Failure to properly route safety belts
over a child's body will cause severe inju­
ries in an accident or other emergency
situation
¢page 149.
- The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat. Ad­
just or remove the rear seat head re­ straint if it is difficult to install the child
seat with the head restraint in place
¢ page 65. Install the head restraint
again immediately once the child seat is
removed . Driving without head restraints
or with head restraints that are not prop­
erly adjusted increases the risk of serious
-
or fatal neck injury dramatically. ~

- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child.
Child Safety 189
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause injury in a crash.
A WARNING
Forward-facing child restraints:
- 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.
- Never put the forward-facing child re­ straint up, against or very near the in­
strument panel.
- 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 forward-facing child restraint. The
backrest must be adjusted to an upright
position.
- Make sure that the PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched

Rearward-facing child restraints:
- A child in a rearward-facing child safety
seat installed on the front passenger
seat will be seriously injured and can be killed if the front 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
armrest, 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. .,.

190 Child Safety
-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
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­
er's instructions when installing a child re ­
straint in your vehicle . To activate the conver­
tible locking retractor:
• Place the child restraint on a seat, prefera­
bly on the rear seat.
• Slowly pull the belt
all the way out.
• Route it around or through the child re­
straint belt path¢,& .
• Push the child safety seat down with your
full weight to get the safety belt really tight.
• Insert the belt tongue into the buckle for
that seating position.
• Guide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat .
• You should hear a "clicking " noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to pull the belt out of the retractor.
The con­
vertible locking retractor is now activated.
• Make sure that the red release button is fac­
ing away from the child restraint so that it
can be unbuckled quickly.
• Pull on the belt to make sure the safety belt
is properly tight and fastened so that the
seat cannot move forward or sideways more
than one inch
(2.5 cm).
_&. WARNING
-
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash.
- 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 during normal driving or in a
crash.
- 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 crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched
into place and cannot fold forward . Oth­
erwise, the seatback with the child safety
seat attached to it could fly forward in

Tether anchors and tether straps
Fig. 182 Tethe r ancho rs: attachment hook locatio ns
behind the rea r sea tbacks
The tether anchors for the rear seating posi­
tions are located on the backside of the rea r
seatbacks
~ fig. 182.
A tether is a straight or V-shaped strap that
attaches the top part of a child restraint to
specia l anchorage points in the veh icle.
The purpose of the tether is to reduce the for·
ward movement of the ch ild restra int in a
crash, in order to help reduce the r isk of head
in ju ry that could be ca used by striking the ve­
hicle interior.
Forward facing child restra ints manufactured
after September 1, 1999, are required by U .S .
federal regulations to comply with new child
head movement performance requirements.
These new performance requ irements make a
tether necessary on most new chi ld safety
seats.
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of injury and death in
a crash.
- Always follow the instructions prov ided
by the manufacturer of the ch ild re­
stra int you intend to install in your Audi.
- Improper use of c hild restra int anchors
(including tether anchors) can lead to in ·
jury in a co llision. Th e anchors are de·
sign ed to withstand only those loads im­
posed by cor rect ly fi tted ch ild restraints.
- Never mou nt two chi ld restraint systems
on one LA TCH lower anchor po int. -
Never attach two child restraint systems
to one tether strap or tether anchorage .
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether ancho­
rages to secure safety belts or other
kinds of occupant restraints.
- Never secure or attac h any luggage or
other items to the LATCH lower ancho­
rages or to the tether anchors.
- If a tether or other strap is used to at­
tach a chi ld restraint to the front passen­
ger seat, make sure that it is not so
tight, that it causes the weight-sensing mat to measure more we ight than is ac­
tually on the seat.
- The heavier weight registered can make the Advanced Airbag System work as
though an adult were o n the seat and de·
p loy the Advanced Airbag when it mus t
be supp ressed causi ng serio us or even
fatal injury to the ch ild .
- If you must ins tall a rearw ard fa cing

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.

oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy­
namic steering*, hill descent assist and selec­
tive wheel torque control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomatically when conditions have returned to
normal.
