& WARNING
Improperly positioned safety belts can cause serious injury in an
accident =:> page
142, "Safety belt position".
• Safety belts offer optimum protection only when the seat back
is upright and belts are properly positioned on the body.
• Never attach the safety belt to the buckle for another seat.
Attaching the belt to the wrong buckle will reduce safety belt effectiveness and can cause serious personal injury.
• A passenger who is not properly restrained can be seriously
injured by the safety belt itself when it moves from the stronger
parts of the body into critical areas like the abdomen.
• Always lock the convertible locking retractor when you are
securing a child seat in the vehicle=:> page
179. •
Safety belt position
Correct belt position is the key to getting maximum
protection from safety belts.
Fig. 127 Head restraint
and safety belt posi­
tion as seen from the side
Use the height adjustment to change the position of the shoulder
straps of the front seat safety belts.
& WARNING
Improperly positioned safety belts can cause serious personal
injury in an accident.
• The shoulder belt portion of the safety belt must be positioned
over the middle of the occupant's shoulder and never across the
neck or throat .
• The safety belt must lie flat and snug on the occupant's upper
body
=> fig. 127 . Pull on the belt to tighten if necessary.
• The lap belt portion of the safety belt must be positioned as
low as possible across pelvis and never over the abdomen. Make
sure the belt lies flat and snug => fig. 127. Pull on the belt to
tighten if necessary.
• A loose -fitting safety belt can cause serious injuries by shifting
its position on your body from the strong bones to more vulner­
able, soft tissue and cause serious injury.
• Always read and heed all WARNINGS and other important infor­
mation => page
140. •

increase the force levels measured by the sensors and ma ke the
a irbag sy ste m d eploy in crashes in which it wou ld not deploy if the
changes had no t been made . Other kinds of changes may reduce
the force levels measured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the driver and front
passenger seat te ll the electronic control module i f the safety belt is
latched or not. If the safety belt is being used, the front airbag will
deploy at a sligh tly h igher rate of vehic le d ece leration than if the
safety belt is not being used. Therefore , in a particular co llision , it is
possible that an ai rbag will not deploy at a seating position where
the safety belt is being used but will inflate at the posi tion where the
safety belt is not being used . It is important tha t nothing interfere
with the safety belt buckles so t hat the sensors can send the co rrect
information about safe ty belt use to the elec tronic control unit.
& WARNING
Changing the vehicle's suspen sion including use of unapproved
tire -rim combinations can change Advan ced Airbag performan ce
and in crease the risk of serious personal injury in a cra sh.
• Never in stall su spen sion compone nts that do not have the
same performance characteristics as the components originally
in stalled on your vehi cle.
• Never use tire -rim combination s that have not been approved
by Audi.
& WARNING
Items stored between the safety belt bu ckle and the center
console can cau se the sen so rs in the buckle to send the wrong
inform ation to the ele ctron ic control module and prevent the
Advanced Airbag System from working properly .
• Always make sure that nothing can interfere with th e safety
belt buckle s and that they are not obstructed.

__________________________________________________ T_ ir_e _ s_ a_ n _ d_ w_ h_ e_ e_ls _ ____. 111111
Unbalanced wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorr ect wheel alignment can cause excessive tire wear, impairing
the safety of the vehicle. If tires show excessive wear, have the
wheel alignment checked by an authorized Audi dealer or qualified
workshop.
All Wheel Drive
Vehicles with quattro ® must always have tires of the same size,
construction and tread type. For details see
=> page 191.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators .
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control .
• Always keep chemicals that can cause tire damage, such as
grease, oil, gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •
New tires and replacing tires and wheels
New tires and wheels have to be broken in.

The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are specially matched to the char­ acteristics of the vehicle and can make a major contribution to good
road holding and safe handling when in good condition and prop ­
erly inflated =>& .
We recommend that al l work on tires and wheels be performed by
an authorized Audi dealer . They are familiar with recommended
procedures and have the necessary special tools and spare parts as
we ll as the proper facilities for disposing of the old tires .
Authorized Audi dealers have the necessary information about tech ­
nical requirements for insta lling or changing tires and rims .
Rep lac ing t ires a nd w heels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together) .
Be sure to read and heed the information to the tire pressure moni ­
toring system =>
page 251.
Always buy replacement radial tires t hat have the same specifica ­
tions as the tires approved for your vehicle by Audi . Replacement
tires must always have the same load rating specification as the
original equipment or approved optional tires listed in the table
=>
page 242.
Audi -approved specification tires are specially matched to your
vehic le and its load limits, and can contribute to the important road- holding, driving characteristics, and safety of the vehicle
. The tab le
( =>
page 242) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure labe l located on driver's side 8 -pillar (=>
page 242,
fig. 161) lists the spec ifications of the original equipment tires
installed on your vehicle at the time it was manufactured.
Federal law requires tire manufacturers to place standardized in for­
mation on the sidewall of all tires=>
page 249, fig. 164 . T his informa­
tion identifies and describes the fundamenta l characteristics, the
quality grade of the tire and also provides a tire identification
number for safety standard certification and in case of a recall.
T ire s pec ifica tio ns
Know ledge of tire specifications makes it easier to choose the
correct tires . Radial tires have the tire specifications marked on the
sidewal l, for example:
P 2 45 / 45 R 17 95 H
This contains the following information :
P Indicates the tire is for passenger cars
24 5 Nominal tire width in mm of the tire from sidewall edge to side-
wa ll edge . In general, the larger the number, the wider the tire
45 Height/width ratio in percent (aspect ratio)
R Tire construction: Radial
17 Rim diameter code (in inches)
95 Load rating code
H Speed rating letter code
X L (or "xi", "EXTRA LOAD", or "RF") indicates that the tire is a"Rein ­
forced" or an "Extra Load" ti re
M+ S (or "M/S") Indicates that the tire has some mud and snow capa ­
bility
The tires could also have the information of direction of rotation =>
page 238.

Wheel bolts
W heel b olts mus t al wa ys be tigh te n ed to t he cor rect
to rqu e.
The design of wheel bolts is matched to the factory instal led rims . If
d ifferen t rims are fitted, the co rrect w heel bo lts wit h th e rig ht length
and correctly shaped bolt heads m ust be used. This ensures that
w hee ls are fitt ed s ecure ly a nd th at t he brake sys te m funct ions
correctly .
I n certain circums tances, yo u may no t use w heel b olts fr om a
differ ent vehicle -even if it is the same model::::;,
page 296.
&_ WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control , a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and th reads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
t ole ranc e of ± 7,4 ft lb(± 1 0 Nm). To rque whee l bolts diag onally.
After changing a wheel, the torque must be checked as soon as possible with a to
rque wrench -preferab ly by an authorized Audi
dea ler o r qu alif ied wo rksh op.•
Low aspect ratio tires
Yo ur Audi is fac tory-equip ped wi th l ow asp ect rati o tires. Th ese tires
have been thorough ly tested and been selected specifically for your
mod el for thei r su per b p erfo rma nce, road feel an d handl in g u nder
a variety of driving conditions . Ask your author ized Aud i dea ler for
mo re deta ils.
T he low aspec t ra tio o f th ese t ires is ind icate d by a numera l o f 55 or
less in the t ire's size designation. The numera l represents the ratio
of the ti re's s idewa ll height in re la ti on to its tread w idth e xpress ed
in percentage. Conventiona l tires have a height/width ratio of 60 or
mo re .
The performan ce of low -aspect -ratio t ires is part icularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and alway s before a
long trip::::;,
page 244, "Checking tire p ressure".
What you can do to a void tire and rim damage
L ow a spect ratio tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particularly if the t ire
is underinflated.
In orde r to minimi ze the occurrence o f im pact da mage to th e tire s
of your vehicle, we recommend that you observe the fo llowing
p reca utions:
• Always ma intain reco mm ende d inflat io n pressu res . C heck your
tire p ressure every 2, 000 miles (3 ,000 km) and add ai r if neces sary .
• D rive car eful ly on roads with potholes, deep gullies or ridges.
Th e impact from d riving th ro ugh o r ove r such o bstac les can
dama ge you r tires . Impact w ith a curb may also cause da mage to
your tires . .,_
