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 chi ldren:
~ A lways use the right chi ld safety seat for each
c h ild and a lways use it properly
c::> page 300.
~ 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 insta ll a
c hi ld safety seat , you must first activate the
conve rtible locking retractor on the safety be lt
to prevent the child safety seat from mov ing
c::> page 305 .
~ Push the child safety seat down wit h 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
c::> page 300 .
Always remember: Even though your vehicle is
equ ipped w ith an Advanced Airbag system, all
children, especially those 12 years and younger,
should always r ide in the back seat prope rly re­
stra ined fo r th eir age and size.
_& WARNING
N ot using a c hild safety seat, usi ng the w rong
c hild safety seat or imp roper ly installing a
298
chi ld restraint increases t he risk of serious
personal injury and death.
- All vehicle occ upants and especially children
must be restra ined properly whenever rid ing
in a vehicle. An unrestrained or improperly
restrained child cou ld be injured by strik ing
the inter ior or by being ejected from the ve­
h icle dur ing a sudden maneuve r o r i mpact.
An unrest rained or imprope rly rest rai ned
child is a lso at g rea ter r is k of inj ury o r death
through con ta ct w it h an infl ati ng a irbag.
- Commerc ia lly availab le child safety seats
a re requ ired to comply with U.S. Federal
Motor Vehicle S afety Standard ( FMVSS) 2 13
(in Canada CMVSS 213).
- When buying a child restra int, select one
that fits your chi ld and the vehicle .
- Only use child restra int systems that fully
contact the flat port ion of the seat cush­
i o n. The ch ild restraint must not tip or
lean to e ither side . Audi does not recom­
mend using child safety seats that rest on
l egs or tube -like frames. They do not p ro­
v ide adequate cont act wi th t he seat.
- Always heed all lega l req uirements per­
ta in ing to the inst allation and use of child
sa fe ty seats and caref ully follow the in ­
str uctions provided by the manufact urer
of the seat you are using .
- Never a llow children under 5 7 inc hes
( 1. 45 meters) 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 t he abdomen and
neck areas dur ing sudden brak ing maneu­
vers or accidents .
- Never let more than one c hild occupy a chi ld
safety seat.
- Never let babies or o lder ch ildren ride in a
ve hicle w hile sitting on the lap of a nother
passenger.
- Holding a c hild in your a rms is never a s ub­
stitute fo r a ch ild restraint system .
- The s tronges t person cou ld no t hold the
c hil d with the forces tha t exist in an acc i­
dent. The c hild will strike the inte rior of
the ve hicle and can also be struck by the
passenger.

Child safety
-Take the child restraint off the front passen­ger 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 immediately.

~
If a child safety seat is used on the rear bench,
especially with LATCH universal lower anchorag­
es, the unused safety belts
must be secured so
that the child in the child restraint cannot reach
them
c::> ,&. .
-Guide the safety belt webbings @and ®* be­
hind the head restraint of the seat where the
c hild restraint is installed
c::>fig. 247. When do­
ing so, do not engage the convertible locking
retractor! You should not hear a "clicking"
sound when winding up the safety belt .
-Let the belt retractor wind up the safety belt
webbing .
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
300 head restraint of the seat where the child
restraint is installed .
- Never activate the convertible locking re­
tractor when routing the safety belts around
the head restraints.
-Never let anyone sit at the center rear seat­
ing position* if the center rear safety belt
has been routed around a rear head re­
straint.
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.

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 ch ildren
should ride only in special restraints in which the
child faces the back of the vehicle. These infant

Properly used convertible child safety seats can
help protect toddlers and children over age one
who weigh between 20 and 40 lbs. (9 and 18 kg)

A toddler or child is usually too large for an in­
fant restraint if it is more than one year old and
weighs more than 20 lbs . (9 kg).
302
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 certified
for their size and weight

c:> fig. 250 .
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, using the wrong
child safety seat or improperly installing a
child 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 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 arm rest, door
or roof.
-Always install rear-facing child safety seats
on the rear seat.
-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 rear side of the child safety seat should
be positioned as close as possible to the
backrest on the vehicle seat.

New tires or wheels
Audi recommends having all work
on tires o r wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowle dge and are eq uipped with
the requ ired too ls and replace­
ment parts.
.,. New tires do not yet have the
optimum g ripping properties .
Drive carefully and at mode rate
speeds for the first 350 miles
(500 km) with new tires.
.,. Only use tires with the same de­
s ign , size (rolling circumfer­
ence), and as close to the same
tread pattern as possible on all
four whee ls .
.,. Applies to: RS models : only use
tires with the same design and
the same tread pattern on all
