serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.
F or example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10- lb (4.5 kg) object are about 20 times the
normal weight of the item. This means that
the we ight of the item would suddenly be
about 200 lbs . (90 kg) . You can imagine the
injuries that a 200 lbs. (90 kg) item flying
freely through the passenger compartment
could cause in a collision like t his.
_& WARNING
Weak, damaged or improper straps used
to secure items to t ie-downs can fail dur­
ing hard braking or in a collision and cause
ser ious personal injury .
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward as dangerous miss iles.
- When the rear seat backrest is folded
down, always use su itab le mounting
straps and properly secure items to the
t ie -downs in the luggage compartment
to help prevent items from flying for­
ward as dangerous miss iles into the pas­
senger compartment.
- Never attach a child safety seat tether
strap to a tie-dow n.

138 Safety belts
Important safety instructions about
safety belts
Safety belts must always be correctly posi­
tioned across the strongest bones of your
body.
,.. Always wear safety belts as illustrated and
described in this chapter.
,.. Make sure that your safety belts are always
ready for use and are not damaged.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death. Safety belts can
work only when used correctly .
- Always fasten your safety belts correctly
before driving
off and make sure all pas­
sengers are correctly restrained.
- For maximum protection, safety belts must always be positioned properly on
the body .
- Never strap more than one person , in­
cluding small children, into any belt.
- Never place a safety belt over a child sit­ ting on your lap.
- Always keep feet in the footwell in front
of the seat while the vehicle is being driv­
en .
- 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 ve­
hicle is moving. Doing so will increase
your risk of be ing injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable
objects 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
hardware .
- Do not wear the shoulder pa rt of the belt
under your arm or otherwise out of pos i­
tion . -
Several layers of heavy clothing may in­
terfere with correct positioning of belts
and reduce the overall effectiveness of
the system .
- Always keep belt buckles free of anything
that may prevent the buckle from latch­
ing securely .
- Never use comfort clips or devices that
create slack in the shoulder belt . Howev­
er, special clips may be required for the
proper use of some child restraint sys­
tems .
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an
accident. Inspect belts regularly .
If web­
bing, bindings, buck les, or retractors are
damaged, have belts replaced by an au ­
thorized Audi dealer or qualified work­
shop.
- Safety belts that have been worn and
loaded in an accident must be replaced
with the correct replacement safety belt
by an authorized Audi dealer . Replace­
ment may be necessary even if damage
cannot be clearly seen . Anchorages that
were loaded must also 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 function of the inert ia reel

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.
The 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 are equipped with a belt pre­
tensioner that helps to tighten the safety belt
and remove slack when the pretensioner is ac­
tivated
c::> poge 142. The function of the pre­
tensioner is monitored by a warning light
c::> page 21.
Convertible locking retractor
Every safety belt except the one on the driver
seat is equipped with a convertible locking re­
tractor 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::> poge 181.
A WARNING
Improperly positioned safety belts can
cause serious injury in an accident
o::> page 139, Safety belt position.
-Safety belts offer optimum protection
only when the seatback is upright and
Safety belts 139
belts are properly positioned on the
body.
- Always make sure that the rear seat
backrest to which the center rear safety
belt* is attached is securely latched
whenever the rear center safety belt is
being used. If the backrest is not secure­
ly latched, the passenger will move for­
ward with the backrest during sudden
braking, in a sudden maneuver and espe­
cially in a crash .
- Never attach the safety belt to the buck­
le for another seat. Attaching the belt to
the wrong buckle will reduce safety belt
effectiveness and can cause serious per­
sonal injury.
- A passenger who is not correctly restrain­
ed can be seriously injured by the safety
belt itself when it moves from the stron­
ger parts of the body into sensitive areas
like the abdomen.
- Always lock the convertible locking re­
tractor when you are securing a child seat in the vehicle

174 Child Safety
-Have the airbag system inspected by
your authorized Audi dealer immediate­
ly.
The child seats listed in categories A to C have been statically tested by Audi only for
the Advanced Airbag function.
Important safety instructions for using
child safety seats
Correc t use of child safety seats substantially
reduces the risk of injury in an accident!
As the driver, you are responsible for the safe­
ty of everybody in the vehicle, especially chil­
dren :
• Always use the right child safety seat for
each child and always use it properly
c:> page 176.
• Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly through the child
safety 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:> page 181.
• 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
cc> page 176.
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children , especially those 12 years and young­
er, should always ride in the back seat proper­
ly restrained for their age and size.
.&_ WARNING
Not using a child safety seat, using the
wrong child safety seat or improperly in­ stalling a child restraint increases the risk
of serious personal injury and death . -
-All vehicle occupants and especially chil­
dren must be restrained properly when­
ever riding in a vehicle. An unrestrained
or improperly restrained child could be
injured by striking the interior or by be­
ing ejected from the vehicle during a
sudden maneuver or impact. An unre­
strained or improperly restrained child is
also at greater risk of injury or death
through contact with an inflating airbag.
- Commercially available child safety seats
are required to comply with U.S. Federal
Motor Vehicle Safety Standard (FMVSS)
213 (in Canada CMVSS 213).
- When buying a child restraint, select one that fits your child and the vehicle.
- Only use child restraint systems that fully contact the flat portion of the seat cushion . The child restraint must
not tip or lean to either side . Audi does
not recommend using child safety
seats that rest on legs or tube-like
frames. They do not provide adequate
contact with the seat.
- Always heed all legal requirements per­
taining to the installation and use of
child safety seats and carefully follow
the instructions provided by the manu­
facturer of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal safety
belt. They must always be restrained by a
proper child restraint system . Otherwise,
they could sustain injuries to the abdo­ men and neck areas during sudden brak­
ing maneuvers or accidents.
- 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 an­
other passenger .
- Holding a child in your arms is never a
substitute for a child restraint system .
- The strongest person could not hold
the child with the forces that exist in
an accident. The child will strike the in­
terior of the vehicle and can also be struck by the passenger.

Child safety seats
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.

178 Child Saf ety
• When using the vehicle safety be lt to insta ll
a chi ld safety seat, you must first activate
the convertible locking retractor on the
safety belt to prevent the child safety seat
from moving ¢
page 181 or install the seat
using the LATCH attachments .
• Push the child safety seat dow n with your
full weight to get the safety belt rea lly t ight
so that the sea t ca nnot move forward or

• Secure unused safety belts on the rear seat
¢ page 176.
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 lers and c hildren who are o lder than one
yea r 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 ch ild safety
seat certified for the ir s ize and weight
¢
fig . 141 and ¢ fig. 142.
The airbag on the passenger side makes the
front seat a potentially dangerous place for a child to r ide . The fro nt seat is not the safest
p lace for a child in a forwa rd-facing child safe­
ty seat.
It is a very dange rous p lace for an in­
fant or a la rger chi ld in a rearwa rd-fa cing seat.
A WARNING
Not u sing a ch ild safety se at, using the
wrong ch ild safety sea t or improper ly in­
stal ling a child restraint increases the risk
of serious personal injury and death in a
co llision or other emergency s ituation.
- Children on t he front seat of any car,
even w ith Advanced A irbags, can be seri­
o usly injured or even killed when an a ir­
bag inf lates. A child in a rearward-facing
child safety seat installed on the front
passenge r seat w ill be seriously injured
and can be kil led if the front ai rbag in-
-
f lates -even with an Advanced Airbag
System .
- The inflating air bag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat
and child aga inst the backrest , center
arm rest, door or roof .
- Always install rear-fac ing ch ild safety
seats on the rear seat .
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptiona l circumstan ­
ces and the

- T he rear side o f the child safety seat
should be pos itioned as close as possi ble
to the backrest on the vehicle seat .
- For a djustable head restra ints: adjust or
remove the rea r seat hea d restra int if it
is difficult to install the c hild seat w ith

page 59. In­
stall the head restraint again immed iate­
ly once the child seat is removed. Dr iv ing

A WARNING
-
If exceptional circums tances require the
use of a fo rward-facing child restraint on
the front passenger 's seat, the child's safe­
ty and well -being require that the follow­
i ng spec ial precautions be taken:
- Make sure the forward- facing seat has
been designed and cert ified by its man u­
facturer fo r use on a front seat with a
passenger front and side airbag.

180 Child Saf ety
you can use the safety belt he ight ad just­
ment to help adjust the shoulder portion
properly .
• Secure unused safety belts on the rear seat
¢ page 176.
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
perts say that the skeletal structure, particu­
larly the pelvis, of these ch ildren is not fully
developed, and they must not use the vehicle
safety belts without a su itab le 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 t he ch ild's body is very
important for the ch ild's protection, whet he r
or not a booster sea t is used . Children age 12
and under must always ride in the rear seat.
C hil dren who are at least 4
ft. 9 in. (57 in­
ches/ 1.45 meters) ta ll can generally use the
vehicle's th ree po int lap and shoulder be lts.
Never use the lap belt portion o f the veh icle's
safety belt a lone to restrain any child, regard­
less of how b ig the child is . Always remember
that ch ildren do not have the pronounced pe l­
vic structure required for the proper function of lap belt portion of the vehicle's three po int
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 possib le around the pelvis. Never le t the lap
be lt portion of the safety belt pass over the
chi ld's stomach or abdomen.
I n a crash, airbags must inflate within a b link
of an eye and with cons iderab le force. In orde r
to do i ts 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 o ut of position and
too close to the airbag ge ts i n the way o f an inflating airbag. When an occ
upant is too
close, he or she will be st ruck violently and
will rece ive serious or possib ly even fatal in­
j ury.
In order for the airbag to offer protection, it is
important that a ll vehicle occupants, especial­
l y any children, who m ust 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
the ch ild's body and the front of the passen­
ger compa rtment, the a irbag can inflate com­
pletely and p rov ide supplementa l prote ction
i n cer tain frontal collisions.
A WARNING
N ot using a booste r 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 persona l injury and death in a collision
or other emergency situat ion. To he lp re­
duce the risk of serious personal injury
and/or death:
- The shou lder belt must lie as close to the
center of the ch ild's collar bone as possi­
b le and must lie flat and snug on the up­
pe r body.
It must neve r lie across the
throat or ne ck. The lap belt mus t lie
across the pe lvis and neve r ac ross the
stomach o r abdomen . Make sure that the
be lt lies flat and snug. P ull on the belt to
tighten if necessary .
- Fai lure to p roperly ro ute safety belts

ries in an accident or other emergency
situation ¢
page 135.
-The rear side o f the child safety seat
should be pos itioned as close as possib le
to the backrest on the vehicle seat.
- For ad justab le head restraints: adjust or
remove the rear seat head restra int if it
is difficult to install the child seat w ith
the head restraint in place¢
