A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death. Safety belts can work only
when used correctly.
-Always fasten your safety belts correctly be­ fore driving off and make sure all passen­
gers are correctly restrained.
- For maximum protection, safety belts must
always be positioned properly on the body.
- Never strap more than one person, includ­
ing small children, into any belt.
- Never place a safety belt over a child sitting
on your lap.
- Always keep feet in the footwell in front of
the seat while the vehicle is being driven.
- Never let any person ride with their feet on
the instrument panel or sticking out the
window or on the seat.
- Never remove a safety belt while the vehicle
is moving . Doing so will increase your risk of
being injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable ob-
jects in or on your clothing , such as eye
glasses, pens, keys, etc., as these may cause
injury.
- Never allow safety belts to become dam­
aged by being caught in door or seat hard­
ware.
- Do not wear the shoulder part of the belt
under your arm or otherwise out of position .
- Several layers of heavy clothing may inter­
fere with correct positioning of belts and re­
duce the overall effectiveness of the system.
- Always keep belt buckles free of anything
that may prevent the buckle from latching
securely .
- Never use comfort clips or devices that cre­
ate slack in the shoulder belt. However, spe­
cial clips may be required for the proper use
of some child restraint systems.
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an acci­
dent. Inspect belts regularly.
If webbing,
bindings, buckles, or retractors are dam-
Safety belts
aged, have belts replaced by an authorized
Audi dealer or qualified workshop.
- Safety belts that have been worn and loaded
in an accident must be replaced with the
correct replacement safety belt by an au­
thor ized Audi dealer. Replacement may be
necessary even if damage cannot be clearly
seen. Anchorages that were loaded must al­
so be inspected.
- Never remove, modify, disassemble, or try
to repair the safety belts yourself.
-Always keep the belts clean. Dirty belts may not work properly and can impair the func­
tion of the inertia reel~

Safe ty belts
Autom ati c s afet y belt retr actors
Every safety belt is equ ipped with an automa tic
be lt retractor on the shoulder belt. This feature
locks the belt when the belt is pulled out fast,
during hard braking and in a n accident . The belt
may a lso lock when you drive up or down a steep
hill or through a sharp curve. Dur ing normal driv­
ing the belt lets you
move freely .

Safety belt position.
- Safety belts offer optimum protection only
when the seatback is upright and belts are
properly positioned on the body.
- Always make sure that the rear seat bac k­
rest to which the center rea r safety belt is
attached is secure ly latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen­
ger will move forward with the backrest dur­
ing sudden braking, in a sudden maneuver
and especially in a crash.
- Never attach the safety belt to the buckle for another seat. Attaching the belt to the
wrong buckle wi ll reduce safety belt effec­
t iveness and can cause serious persona l in­
jury.
- A passenger who is not properly restrained can be seriously in ju red by the safety be lt it­
self when it moves from the stronger parts

of the body into critical areas like the abdo­ men.
- Always lock the convertible locking retractor
when you are securing a child safety seat in

A WARNING
To reduce the risk of serious injury, make sure
that the
PASSENGER AIR BAG OFF light
comes on and stays on whenever a child re­
straint is installed on the front passenger seat
and the ignition is switched on.
Child safety
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on.
- Have the airbag system inspected by your
authorized Audi dealer immed iately.

The child seats listed in categor ies A to C have
been statically tested by Audi only for the Ad­
vanced Airbag function.
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 responsible for the safety
of everybody in the vehicle, especially children:
.,. Always use the right child safety seat for each
child and always use it properly ¢
page 140 .
.,. Always carefully follow the chi ld safety seat
manufacturer's instructions on how to route
the safety belt properly through the child safe­ ty seat.
.,. When using the vehicle safety belt to install a
child safety seat, you must first activate the
convertible locking r etractor on the safety belt
to prevent the chi ld safety seat from moving
~page 144.
.,. Push the chi ld safety seat down with yo ur 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 measu re more weight
than is actually on the seat.
.,. Secure unused safety belts on the rear seat
~page 139.
Always remember: Even though your veh icle is
equipped with an Advanced Airbag system, all
children, especia lly those 12 years and younger,
shou ld a lways ride in the back seat proper ly re-
strained for their age and s ize.

A WARNING
-
A child in a child safety seat installed with the LATCH lower anchorages or with the standard
safety belt or a child in a booster seat on the rear seat could play with unused rear seat
safety belts and become entangled. This
could cause the child serious personal injury
and even death.
- Always secure unused rear seat safety belts
out of reach of children in child seats such
as by properly routing them around the head restraint of the seat where the child

Child safety
Child safety seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or 9 kg need special rearward -facing
child restraints that support the back, neck and
head in a crash.
Fig. 121 Schema tic overv iew: rearwa rd -facing infan t sea t,
properly installe d on the rea r 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
c::>poge 144 or install the seat using the LA TCH
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) .
• Secure unused safety belts on the rear seat
c::>page 139.
Infants up to about one year (20 lbs. or 9 kg) are
best protected in special infant carriers and child
safety seats des igned for their age group. Many
experts believe that infants and small children
should ride only in spec ial restraints in which the
child faces the back of the veh icle. These infant
seats support the baby 's back, neck and head in a
crash
c::> fig . 121 .
The airbag on the passenger 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 forward -facing child seat.
It is a very
dangerous place 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 or improperly installing a
child restraint increases the risk of serious
personal injury and death in a crash .
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat -even w ith an Advanced A irbag System .
A child will be serio usly injured and can be
killed when the inflating airbag hits the
child safety seat or infant carrier with great
force and smashes the child safety seat and
child against the backrest, center armrest,
door or roof
c::> page 115, Child restraints on
the front seat -some important things to
know .
-Always install rear-facing child safety seats
or infant carriers on the rear seat.
- Never install a rear-facing child restraint in
the forward-facing direction. Such restraints
are designed for the special needs of infants
and very small children and cannot protect
them properly if the seat is forward-facing.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of 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 airbag system
inspected by your Audi dealer.

The airbag on the passenger 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 forward -facing child safety seat. It is a
very dangerous place for an infant or a larger
child in a rearward-facing seat .
_&. WARNING
Not using a child safety seat, us ing the wrong
child safety seat or improperly instal ling a
chi ld restraint increases the risk of serious
personal injury and death in a collision or oth ­
er emergency situation.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates.
A child in a rearward-facing ch ild safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System .
- The inflating airbag will hit the child safety
seat or infant carr ier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof.

come on and stay on, immediately install
the rea r-facing child safety seat in a rear
seating position and have the a irbag system
inspected by your Audi dealer .
- The rear side of the ch ild safety seat shou ld
be positioned as close as possible to the
backrest on the veh icle seat. Adjust or re­
move the rear seat head restraint if it is dif-

~ Secure unused safety belts on the rear seat
¢ page 139.
Children up to at least 8 years old (over 40 lbs. or
18 kg) are best protect ed in child safety s eats de­
signed for their age and weight. Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restra int .
It is usually best to put these children in appro­ priate booster seats . Be sure the booster seat
meets all applicable safety standards .
Booster se ats 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 rout ing of
the belt over the child's body is very important
for the child's protection, whether or not a boos­
ter seat is used. Chi ld ren age 12 and unde r must
a lways ride in the rear seat .
Ch ildren who are at least 4 ft . 9 in. (57 inches/
1.45 mete rs) tall ca n genera lly use the veh icle's
three po int lap and shoulder be lts. Neve r use the
l ap belt po rtion of the vehicle 's safety belt alone
to restrain any child, regardless of how big the
chi ld is. A lways remember that children do not
hav e the pronounced pelvic structure required for
the proper function of lap belt port ion of the ve­
h icle 's three point lap and shoulder be lt s. The
chi ld 's safety absolutely requires that a lap belt
port ion 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, a irbags must inflate within a blink of
an eye and wit h considerable force . In order to do
its job, the airbag needs room to inflate so that it
will be there to p rotect the occupant as the occu­
pant moves forward into the a irbag.
A vehicle occupant who is out of position and too
close to the airbag gets in the way of an inflating
ai rbag. When an occ upant is too close, he o r she
will be struck v iolently and will receive ser ious or
possibly even fatal injury.
Ch ild safety
In order for the a irbag to offer protection, it is
important that a ll vehicle occupants, especially
any ch ildren, who m ust be in the front seat be­
cause of exceptiona l circumstances, be properly
res tra ined and as far away from the airbag as
poss ible. By keeping room between the child 's
body and the front of the passenger compart­
ment, the a irbag can inflate completely and pro­
vide s upplementa l protec tion in certain frontal
collisions.
A WARNING
-
Not using a booster seat, using the booster
seat improperly, incorrect ly installing a boos ­
ter seat or using the vehicle safety belt im­
properly increases the risk of serious personal
i njury and death in a collision or other emer­
gency situation. To help reduce the risk of se­ rious personal injury and/or death:
- The shou lder belt must lie as close to the
center of the ch ild'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 ac ross the pelvis
and never across the stomach o r abdomen.
Make sure the bel t lies flat and sn ug. Pu ll on
the belt to tighten if necessary.
- Fail ure to properly route safety bel ts over a
child's body w ill cause severe injuries in an
accident or other emergency situation
¢ page 106.
- The rear side of the chi ld safety seat should
be positioned as close as possible to the
backrest on the vehicle seat. Adjust or re ­
move the rear seat head restraint if it is dif­
f icult to insta ll the ch ild seat with the head
restraint in place¢
page 44 . Install the
head restraint again immed iately once the
child seat is removed . Driving without head
rest raints or with head restra ints that a re
not properly adj usted increases the r is k of
serio us or fatal ne ck in jury dramatically .
- Never let a chi ld put the shoulder belt under
the arm or behind the ba ck, because i t could
cause severe inj uries in a crash .
- Ch ild ren on the fron t seat of any car, even
with Advanced Airbags, can be seriously in-
jured or even ki lled when an airbag inflates .
