Automatic saf ety belt retractor s
Every safety be lt is equ ipped with an automatic
be lt retractor on the shoulder belt. Th is feature
l ocks the belt when the belt is pull ed out fast,
during hard braking and in an accident. The be lt
may a lso lock when you drive up or down a steep
h ill or through a sharp curve. During normal driv­
ing the belt lets you move freely .

Safety belt position.
-Safety belts offer optimum protection only
when the seatback is upright and belts are
prope rly pos itioned on the body.
-Always ma ke sure tha t the rear seat bac k­
rest to wh ich the center rear safety be lt is
attached is secure ly latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen­
ger will move forward with the backrest dur­
ing sudden braking, in a sudden maneuver
and especially in a cras h.
-Never attach the safety belt to the buckle
for another seat. Attaching the belt to the
wrong buckle w ill reduce safety belt effec­
t iveness and can cause serious personal in­
jury.
-A passenger who is not properly restrained can be seriously in jured by the safety be lt it­
self when it moves from the stronger parts

Improperly worn safety belts
Incorrectly positioned safety belts can cause se­
vere injuries .
Wearing safety belts improperly can cause seri­
ous injury or death . Safety belts can only work
when they are correctly pos itioned on the body .
Imp roper seating positions reduce the effect ive­
n ess of safety be lts and will even inc rease the
ris k of injury and death by mov ing the safety belt
to cr it ic al areas of the body. Imp roper sea ting
positions also increase the risk of serious inj ury
and death when an airbag deploys and strikes an
occupant who is not in the co rrect seating posi ­
tion . A driver is respons ible for the safety of all
ve hicle occupants and espec ia lly for children.
Therefore:

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 . 245 Rea r seat: chi ld p roper ly restrained in a booster
sea t
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 children 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 chi ld on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child's collar bone as possib le and
must lie fla t 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
¢page 297.
Children up to at least 8 years old (over 40 lbs. or
18 kg) are best protected in chi ld safety seats de-
~ signed for their age and we ight. Experts say that .....

Child safety
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 applicab le 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 chi ld's body in the right places. The routing of
the be lt over the chi ld's body is very important
for the ch ild'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 ch ild, regard less of how big the
ch ild is. Always remember that child ren 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 shoulde r 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 pe lvis . 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 considerab le 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 pan t moves forward into the airbag .
A vehicle occ upant who is out of position and too
close to the a irbag gets in the way of an inf lating
airbag. When an occupant is too close , he or she
will be struck violent ly and w ill rece ive serious or
poss ibly even fata l injury .
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any ch ildren, who must be in the front seat be­
cause of exceptiona l circumstances, be properly
restrained and as far away from the airbag as
poss ible. By keeping room between the child's

reinforced by ply cords and that is
shaped to fit the rim.
Bead separation
means a breakdown of the bond
between components in the bead.
328
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the t ire pressure recom­
mended by the vehicle manufac­
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo ­
meters) at low speeds in the
three hour period before the tire pressure is measured or adjusted.
Curb weight

Wheels
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easi ly.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces . These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
d isassemble them
C> _&. .
_& WARNING
Wheel bolts that are tight ened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
e> page 356, Finishing.
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourse lf, because this increases the risk
of an accident.
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions . Be ­
cause of their construction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow.
"'Use winter tires on all four wheels .
"'Only use winter tires that are approved for your
vehicle .
"'Please note that the maximum permitted
speed may be lower with winter tires
e> & in
General information on page 325.
An author­
ized Audi dealer or authorized Audi Service Fa­
cility can inform you about the maximum per­
mitted speed for your tires .
"'Check the tire pressure after installing wheels
¢page 335.
340
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.16 in (4 mm) . The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
Snow cha ins not only improve the driving in win­
ter road conditions, but also the braking.
"'Only install snow chains on the rear wheels.
"' Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer.
"'Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0 .53 in (13.S mm) in height, including
the chain lock.
You must remove the snow chains on roads with­
out snow . Otherwise, you could impair driving
ability and damage the tires .
_& WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
9"'

control, which increases the risk of an
accident.
@ Note
-Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them . Remove the wheel covers*
first. Use coated snow chains.
-Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch the offroad mode on <=>
page 141.
Low-profile tires
App lies to: ve hicles with low -profile tires
Compared to other tire/rim combinat ions, low­
profile tires offer a wider tread surface and a
l arger r im diameter with shorter tire sidewalls.
This results in an agile dr iv ing style. However, it
may reduce the leve l of comfort and increase
road noise when driving on roads in poor condi­
tion .
L ow -profile tires can become damaged more
quickly than standard tires when driving over
l arge bumps, potholes, manhole covers, and
curbs . Therefore, it is particular ly important to
maintain the correct tire pressure<=>
page 335 .
To reduce the risk of damage to the tires and
rims, drive very carefu lly on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. Fo r example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediate ly by
an authorized Audi dealer or authorized Audi
Service Facility .
Lo w-profile tires can wear out faster than stand­
ard tires.

Uniform tire quality grading
-Tread wear
-Traction AA ABC
-Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width <=>
page 326, fig. 266.
For example: Tread wear 200 , Traction AA, Tem­
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled cond it ions on a specified gov ­
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as we ll on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual cond it ions of the ir use, however, and
may depa rt significantly from the norm due to
variations in driv ing habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA , A, Band
C. Those grades represent the tire's
ability to stop o n wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
c:>,& .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
