1 70 Child Safety
-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 in 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 air­
bag system inspected immediately by
your Audi dealer.
_&, WARNING
- Forward-facing child seats installed on
the front passenger seat may interfere
with the deployment of the airbag and
cause serious personal injury to the
child.
- If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger 's seat, the child's
safety and well-being require the follow­ ing special precautions to be taken:
- Always make sure that the forward-fac­
ing seat has been designed and certi­
fied by its manufacturer for use on a
front passenger seat with a front and
side airbag.
- Always carefully follow the manufac­
turer's instructions provided with the
child seat or infant carrier.
- Never install a child restraint without a
properly attached top tether strap if
the child restraint manufacturer's in­
structions require the top tether strap
to be used.
- Never put the forward-facing child re­
straint up against or very near the in­
strument panel.
- Always set the safety belt upper an­
chorage to the adjustment position
that permits proper installation in ac­
cordance with the child restraint manu­
facturer's instructions.
-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 in­
stalling the child restraint. The back­
rest must be adjusted to an upright po­
sition .
- Always make sure that nothing pre­
vents the front passenger's seat from
being moved to the rearmost position
in its fore and aft adjustment range.
- Never place objects on the seat (such
as a laptop, CD player, electronic
games device, power inverter or seat
heater for child seats) . These may in­
fluence the electrical capacitance
measured by the capacitive passenger
detection system and can also fly
around in an accident and cause serious
personal injury.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat
heater for child seats) on the front pas­
senger seat if the device is connected
to the 12 -volt socket or the cigarette
lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passen­
ger seat, never install any child re­
straint system on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or
other liquids on the front passenger
seat cushion .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the forward-facing child seat in a rear seating position and have
the airbag system inspected by your
authori zed Audi dealer.
- Always buckle the child seat firmly in
place even if a child is not sitting in it.
A loose child seat can fly around during
a sudden stop or in a collision.

174 Child Safety
-The child and the passenger can also
injure each other in an accident.
- Never install rear-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen­ ger 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 install rear-facing child safety
seats or infant carriers on the rear seat.
- Forward-facing child safety seats instal­
led on the front passenger's seat can in­
terfere with the airbag when it inflates
and cause serious injury to the child. Al­
ways install forward-facing child safety
seats on the rear seat.
- If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safety and well-being require that the
following special precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its man­
ufacturer for use on a front seat with a
passenger front and side airbag.
- Always carefully follow the manufac­
turer's instructions provided with the
child safety seat or carrier.
- Always move the front passenger seat
into the rearmost position of the pas­
senger seat's fore and aft adjustment
range, and as far away from the airbag
as possible before installing the child
restraint.
- Always make sure that nothing pre­
vents the front passenger's seat from
being moved to the rearmost position
in its fore and aft adjustment range.
- Always make sure that the backrest is
in the upright position .
- Never place or use any electrical device (such as a laptop, CD player, electronic
games device, power inverter or seat heater for child seats) on the front pas­
senger seat if the device is connected
to the 12-volt socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passen­
ger seat, never install any child re­
straint system on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or
other liquids on the front passenger seat cushion .
- Never place objects on the seat (such
as a laptop, CD player, electronic
games device, power inverter or seat
heater for child seats) . These may in­
fluence the electrical capacitance
measured by the capacitive passenger
detection system and can also fly
around in an accident and cause serious
personal injury.
- 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 .
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used

1 76 Child Safety
& 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 in a
crash .
- Never install rear-facing child safety
seats or infant carriers on the front pas­
senger seat - even with an Advanced Air­
bag System. A child will be seriously in­
jured and can be killed when the inflat­
ing airbag hits the child safety seat or in­
fant carrier with great force and smashes
the child safety seat and child against
the backrest, door or roof¢
page 148,
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 re­
straints 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 because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child

er socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or other liquids on the front passenger seat
cushion.
- Never place objects on the seat (such as
a laptop, CO player, electronic games de­
vice, power inverter or seat heater for
child seats). These may influence the
electrical capacitance measured by the

1 78 Child Safety
- Always move the front passenger seat in­
to the rearmost position of the passen­
ger seat's fore and aft adjustment range,
and as far away from the airbag as possi­
ble before installing the child restraint .
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its
fore and aft adjustment range.
- Always make sure the backrest is in an
upright position .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat
heater for child seats) on the front pas­
senger seat if the device is connected to
the 12-volt socket or the cigarette light­
er socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or
other liquids on the front passenger seat
cushion.
- Never place objects on the seat (such as
a laptop, CD player, electronic games de­
vice, power inverter or seat heater for
child seats). These may influence the
electrical capacitance measured by the
capacitive passenger detection system
and can also fly around in an accident
and cause serious personal injury .
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched

Booster seats and safety belts
Properly used booster seats 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. tall. 9 in. (57 inches/1.45 meters)
tall.
Fig. 1S2 Rear seat : child properly restrained in a boos·
te r 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 meters) tall and weigh about
80 lbs .
(36 kg). Booster seats raise these chil ­
dren up so that the safety belt will pass prop­
erly over the stronger parts of their bodies
and the safety belt can help protect them in a
crash.
" Do not use the convertible locking retractor
when using the vehicle's safety belt to re­
strain a child on a booster seat.
"The shoulder belt must lie as close to the
center of the child'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 across the pelvis
and never across the stomach or abdomen.
Make sure the belt lies flat and snug . Pull on
the belt to tighten if necessary .
"Secure unused safety belts on the rear seat

Children up to at least 8 years old (over 40 lbs
or 18 kg) are best protected in child safety
seats designed for their age and weight . Ex­
perts say that the skeletal structure, particu­
larly the pelvis, of these children is not fully ...

230 Tires and wheels
-If you notice unusual vibra­
tion or if the vehicle pulls to
one side when driving, al­
ways stop as soon as it is
safe to do so and check the
wheels and tires for dam­
age.
0 Note
-Please note that summer and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­
ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability. If summer tires are used
in
very cold temperatures, cracks can form on the tread
bars, resulting in perma­
nent tire damage that can
cause loud driving noise and
unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power
steering, power brakes, power
windows, power seats, radio, and heater, to the extent that
these items are available as fac­
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indi­
cate a low sidewall for im­
proved steering response and
better overall handling on dry
pavement.
