Important safety instructions for using
child safety seats
Correc t use of child safety sea ts substan tially 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 a lways use it properly~
page 283.
~ Always carefully follow the child safety seat
manufacturer 's instructions on how to route
the safety belt properly through the child safe­
ty seat .
~ When using the vehicle safety be lt to install a
child safety seat , you must first activate the
convertible locking retractor on the safety be lt
to prevent the child safety seat from moving
¢ page 288.
~ Push the child safety seat down with your fu ll
weight to get the safety be lt 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
¢ page 283 .
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
strained fo r their age and size.

child restraint increases the risk of serious
personal injury and death.
- All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestra ined or improperly
restrained child could be injured by striking
the inter ior or by being ejected from the ve­
hicle dur ing a sudden maneuve r or impact .
An unrest rained or improperly restrained
child is a lso at greater r is k of injury or death
through contact w ith an inflating a irbag.
- Commerc ially availab le child safe ty seats
are requi red to comply with U.S . Federal
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213).
- When buying a child restra int, select one
that fits your ch ild and the vehicle .
- Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion. The ch ild restraint must not t ip or
lean to either side . Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide adequate contact with the seat.
- Always heed all lega l requirements per­
ta ining to the insta llation and use of child
safety seats and carefu lly follow the in­
structions provided by the manufacturer
of the seat you are using .
- Never a llow children under 57 inches
(1.45 mete rs) to wear a normal safety be lt.
They must a lways be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to the abdomen and
neck areas during sudden braking maneu­
vers or accidents .
- Never let more than one child occupy a child
safety seat.
- Never let babies or o lder children ride in a
vehicle while sitting on the lap of another
passenger .
- Holding a child in your arms is never a sub­
stitute for a chi ld restrain t system .
- The strongest person cou ld not ho ld the
ch ild with the forces that exist in an acci­
dent. The child will strike the interior of
the vehicle and can also be struck by the passenger.

been routed around a rear head restraint.
Child 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.

To ddlers 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 certi­
fied for their size and weight

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.
-Al ways install rear-fa cing child safety seats
on the rear seat .
- If you must insta ll a rearward facing child
safety seat on the front passenger seat be­
cause of excep tional circumstances and the
PASSENGER AIR BAG OFF '-I; light does not

- 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
f icult to install the child seat with the head

Child safety
-Never put the forward-facing child restraint
up, against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest position in the up and down ad­
justment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible, before installing the for­
ward-facing child restraint.
- Always make sure that the safety belt upper
anchorage is behind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi­
tioned.
- Make sure that the

A WARNING
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 Ad­
vanced 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 in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances .
- Make sure that the
PASSENGER AIR BAG

· Activating the convertible locking retractor
Use the convertible locking retractor to secure a
child restraint.
Always heed the child safety seat manufacturer 's
instructions when installing a child restrain t in
your vehicle . To activate the convertible locking
retractor:
.. Place the child restraint on a seat, preferably
on the rear seat .
.. Slowly pull the belt
all the way out .
.. Route it around or through the child restraint
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 un­
til 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 con ­
vertible locking retractor by pulling on the belt.
You should no longer be able to putt the belt
out of the retractor. The convertible locking re­
tractor is now activated .
.. Make sure that the red release button is facing
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) .
A WARNING
Using the wrong child restraint or an improp­
erly 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 retrac­
tor 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.
