I nfants up to about one year (20 lbs . or 9 kg)
are best protected in specia l infant carriers
and chi ld safety seats des igned for their age
group. Many experts believe that infants and
small children should ride only in special re­
straints in which the child faces the back of
the vehicle. These infant seats support the ba·
by's back, neck and head in a crash

A WARNING
-
Not using a child safety seat, using the
wrong child safety seat or improperly in­
stalling a ch ild restra int increases the risk
of ser ious personal in jury and death in a
crash.
- Never install a rear-fac ing ch ild restra int
in the forward-fac ing direct ion. Such re­
straints are designed for the special
needs of infants and very small ch ildren
and cannot protect them properly if the
seat is forward-facing.

136 Child Safet y
Booster seats and safety belts
Properly used booster s eats 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 . 120 Passenger seat: child proper ly rest ra in ed in a
booster 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 mete rs) tall and weigh about
80 lbs . (36 kg). Booster seats ra ise these chil­
dren up so that the sa fety belt will pass p rop ­
erly over the stronger pa rts of their bodies
and the safety belt can help protect them in a
crash.
.. Do no t use the co nvertible locki ng retractor
when using the vehicle's safety belt to re­ strain a chi ld on a booster seat .
.. The shoulder be lt must lie as close to the
center of the child 's collar bone as possible
and must lie 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 f lat and snug . Pull on the be lt
to t ighten if necessary.
Ch ildren up to at least 8 years old (over 40
l bs. or 18 kg) are best protected in ch ild safe­
ty seats designed fo r their age and weight . Ex­
pe rts say that the ske leta l structure, pa rticu­
larly the pelvis, of these ch ildren is not ful ly
developed , and they m ust not use the vehicle
safety belts without a suitab le child restraint.
It is us ually best to put these childre n in ap­
propriate booster seats . Be sure the booster
seat meets all applicab le safety standards. Booster seats raise the seating position of the
c
h ild and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the ch ild's body in the right p laces. The
ro uting of the belt over the child's body is very
important for the child's protect ion, whether
o r not a booster seat is used .
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 port io n of the vehicle's
safety belt alone to restrain any ch ild, regard­
less of how big the chi ld is. A lways remember
that children do not have the prono unced pel­
vi c structure required for the proper funct ion
of lap be lt portion of the vehicle's three point
lap and shou lde r belts . T he child 's safety ab ­
solutely 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 be lt pass over the
c hi ld 's stomach or abdomen.
In a crash, a irbags must inflate within a blink
of a n eye and wi th considerable force. In order
to do its job, the airbag needs room to inflate
so that it will be the re to protect t he occupant
as the occupant moves forwa rd into the a ir­
bag .
A vehicle occupant who is out of posit ion and
too close to the a irbag gets in t he way of an
inflating airbag . When an occupant is too
cl ose, he or she w ill be struck v iolently and
will receive serious or possibly even fatal in ­
Jury .
In order for the airbag to offer prote ction, it is
importan t that a ll vehicle occupa nts, espe cial­
ly any childre n, who m ust be in t he front se at
because of exceptiona l circumstances , be
proper ly restrained and as fa r away from the
airbag as possible. By keeping room between
the chi ld's body and the front of the passen­
ger compartment, the airbag can inf late com­
pletely and prov ide supplemental protection
in certain frontal collisions .

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 collision
- 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, door or
roof.
- Forward-facing child safety seats or in ­
fant carriers installed on the front pas­
senger's seat may interfere with the de­
ployment of the airbag and cause serious
injury to the child.

A WARNING
-
Always take special precautions if you
must install a forward or rearward-facing
child restraint on the front passenger's
seat in exceptional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front
passenger seat, the
PASSENGER AIR
BAG OFF
light must come on and stay on
whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, perform
the checks described
~ page 118, Moni­
toring the Advanced Airbag System.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on whenever
the ignition is switched on the inflating
airbag will hit the child safety seat or in­
fant carrier with great force and will smash the child safety seat and child
against the backrest, door or roof . Have
the airbag system inspected immediately by your Audi dealer . -
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.
- 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
on .
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 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

General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
Avoiding damage I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sid ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.

A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in jur ies, d rive w ith special ca re fo r the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.

Tire pressure genera lly refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents. Tire pressure is
measured in kilopascals (kPa), the interna­
tional measuring unit and in pounds per
square inch (PSI). Tire pressure is based in
part on the vehicle's design and load limit -
the greatest amount of we ight that the vehi­
cle can carry safe ly and the tire size. The prop­
e r tire pressure is freq uent ly referred to as the
"recommended cold tire inflation pressure."
A ir in the tires expands when the tire heats up
because of interna l frict ion when it flexes in
use. The t ire pressure is higher when the tire
has warmed up than when it is "cold." It is the
inflation pressure in a "cold" tire that counts.
Therefore, you shou ld never let air out of a
warm tire to match "cold tire inflation pres­
sure " recommendations. The tires would then
be underi nflated and could fail suddenly .
Maintaining proper tire pressure is one of the
most important things you can do to help
avoid sudden tire failure. Underinflated tires
are a major cause of sudden tire failure . K eep­
ing tires at the rig ht pressure is also impor­
tant for sa fe and responsive vehicle handling,
traction, braking and load carrying.

sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci­
ties approved for your vehicle.
The recommended tire pressures for your Audi
depe nd on the kind of tires on your vehicle
and the number of passengers and/or amount
of luggage you will be transporting.
Th e tire pressure label is located on the driv­
er's side B-pillar . The tire pressure labe l lists
the recommended cold tire inflation pressures
for the vehicle at its maximum capac ity
weight and tires that were on your veh icle at
the time it was manufactured .
If you wish to improve comfort when operat­
ing the vehicle at normal load (no luggage)
up to 2 occupants, you can adjust tire pres­
sures to those specified for normal vehicle
load. Before operating the vehicle at maxi­
mum load, you must increase the tire pres­
sures to those specified for maximum vehicle
load ~&. -
Bear in mind that the tire pressure monitoring
system can only monitor the tire pressures ..,.
