Child safety
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. (57 inches/1.45 meters) tall .
Fig. 167 Rear seat: child properly restrained 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 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these chi ldren up so
that the safety belt will pass properly
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 restrain
a child on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter 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 tight­
en if necessary .
.. If you must transport an older child in a boos­
ter seat on the front passenger seat, you can use the safety belt height adjustment to help
adjust the shoulder portion properly .
.. Secure unused safety belts on the rear seat
c>page 176.
Children up to at least 8 years old (over 40 lbs or
18 kg) are best protected in child safety seats de­
signed for their age and weight. Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
180
must not use the vehicle safety belts without a
suitable child restraint .
It is usually best to put these children in appro­
priate 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 be lt over the child's body is
very important
for the child's protection, whether or not a boos­
ter seat is used. Children age 12 and under must
always ride in the rear seat.
Children who are at least 4
ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle 's
three point lap and shoulder belts. Never use the
lap belt portion of the vehicle's safety belt alone
to restrain any child, regardless of how big the
c hi ld is. Always remember that children do not
have the pronounced pelvic structure required for
the proper function of lap belt portion of the
ve­
hicle's three point lap and shoulder belts. The
child's safety absolutely requires that a lap belt
portion of the safety belt be fastened snugly and
as low as possible around the pelvis. Never let
the lap belt portion of the safety belt pass over
the child's stomach or abdomen.
In a crash, airbags must inflate within a blink of
an eye and with considerable force. In order to do its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­ pant moves forward into the airbag .
A vehicle occupant who is out of position and too close to the airbag gets in the way of an inflating
airbag. When an occupant is too close, he or she
will be struck violently and will receive serious or possibly even fatal injury .
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any children, who must be in the front seat be­
cause of exceptional circumstances, be properly
restrained and as far away from the a irbag as
possible. By keeping room between the child's

New tires or wheels
Audi recommends having all work
on t ires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
know ledge and are eq uipped with
the required too ls and rep lace­
ment parts.
1>- New tires do not yet have the
optim um gripping properties.
Drive carefully and at moderate
speeds for the first 35 0 m iles
(500 km) with new tires .
1>-Qnly use tires with the same de­
sign, size ( rolling circumfer ­
ence) , and as close to t he same
tread pattern as possible on a ll
four wheels .
.,.Applies to: RS models: only use
tires with the same design, size (ro lling circumfere nce), and the
same tread pattern on all four

A WARNING
Please note the important safe ­
ty precautions regarding tire
pressure
¢ page 215 and load
limits¢ page 218.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to loss of vehicle control, but can al ­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflat ion that can
cause the vehicle to crash .
Your safety and that of your pas ­
sengers also depends on making
sure that load limits are not ex­
ceeded . Vehicle load inc ludes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR") .
T he "GVWR" inc ludes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
2 18
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs . (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the veh icle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehic le load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
The fact that there is an upper limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehic le (inc luding
the weight of a trailer h itch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage .

A WAR NING
-
Overloading a vehicle can cause
loss of vehicle contro l, a crash
or other accident, serious per­
sonal injury , and even death .
-Carrying more weight than your vehic le was designed to
carry will p revent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been over loaded may not
be able to stop the veh icle
within a safe dis tance .
-Tires on a vehicle that has been overloaded can fail sud­
d en ly , including a blowout and
sudden deflation, causing loss
of control and a crash .
-Always make su re that the to­
tal load being transported -
includ ing the weight of a trail ­
er hitch and the tongue
we ight of a loaded trailer -
d oes not make t he vehicle
heavier than the vehicle's
Gross Vehicle We ight Rating .

Determining correct load
limit
Use the example below to calcu ­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload­
ed .
Steps for Determining Correct
Load Limit
1 . L ocate the statement " THE
COMB INED W EIGH T OF OCCU­
PANTS AND CARGO S HOU LD
NEVER EXCEED XXX KG OR XXX
L BS" on your vehicle's placard
(tire inflation pressure label)
¢ page 215, fig. 189 .
2. Determine the combined
weight of the driver and pas­
sengers that w ill be riding in
your vehicle .
3 . Subtract the combined weight
of the driver and passengers
from
" XXX " kilog rams or " XXX "
pounds shown on the sticker
¢page 215, fig. 189 .
4. T he resulting figure equals the
available amount of cargo and luggage load capacity. For ex­

Vehicle transport
Applies to: vehicles with air suspension
~ Note
When transporting the vehicle on a car carri­
er, train , ship or by other means, only tie the
vehicle down at the running surface of the
tires, which is the outer circumference. Secur­
ing the vehicle at the axle components, sus­
pension struts or towing eyes is not permitted
because the pressure in the air suspension
struts can change during transport. The vehi­
cle may not be secured sufficiently if this hap­
pens.
