recognize the load condition of your vehicle.
The effectiveness of the ti re pressu re monitor­

mal load pressures but then operate the vehi ­

See the illustration¢

of the label on dr iver's side B-pillar (color of
the actual labe l and exact location on the ve­

Note that the fo llowing tab le is accurate at
the t ime o f go ing to press and is subject to change. In the
event of discrepancies, the ti re
pressure label (on driver's side B-pi llar) always
takes precedence .

Perfo rmance
X L= r einf orced or extra lo ad tire. It ma y al so app ear a s xl, EX TR A LO AD, or RF on the tir e side-
wa ll.
The correct tire pressure for the spare wheel is
located on a label on the driver's side B-pillar.
Because technical changes may be made to
vehicle equ ipment during the model year, al­
ways compare the tire size designation on the
tire pressure label on your vehicle w ith the
tires on your vehicle. Ma ke sure that the tire
size information on the veh icle label is the same
as the size of the tires on the veh icle.
Th is is espec ially important if the veh icle be­
longs to someone else o r you boug ht the vehi­
cle w ith diffe rent rims/tires or you bought the
vehicle as a prev iously owned vehicle.
Remember, your safety and that of your pas-
sengers also depends on making sure that

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 227.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile driving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 197
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 186, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.

Handling characteristics change when
driving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characteristics by pu lling the vehicle
slightly to the side where the tire is mounted
and reduces braking performance .
A low pressure or flat
rear tire also affects
driving character istics by pulling to the side
where the tire is mounted and also reduces
brak ing performance. The effect on vehicle
handling is most not iceable when driving
around curves.
A WARNING
Changed vehicle handling character istics
when driving in the run -f lat mode can
cause loss of vehicle contro l, a crash and
serious personal injury.
- Driving on special run-flat tires in the
run-f lat mode wi ll change vehicle han­
dling characteristics during braking,
when cornering and under heavy acceler­
ation.
- Never drive faster than the maximum
rated speed of 50 mph (80 km/h) when
dr iv ing in the run -flat mode.
- Always adjust vehicle speed to traffic,
road and weather cond itions and drive
slower than the max imum rated speed if
necessary weather and road conditions
are taken into account.
- Always obey speed limits and other traf­
fic laws.
Q) Note
We always recommend driving w ith even
more care when using these special t ires in
the run-flat mode . Always avo id sudden
maneuvers.
Tires and wheels 203
Replacing run-flat tires and rims
App lies to veh icles : w it h Run -flat t ires
Your vehicle was especially designed to use
special run-flat tires.
You may use and combine only approved run­
flat tires and special matching rims that have
been designed for run-flat tires. Mounting
special run-flat tires on standard wheels will not work and w ill not prov ide the advantages
fo the ru n-falt feature . Never use spec ial run­
flat tires on standa rd wheel rims.
After dr iving with a tire i n the run-flat mode,
always have the veh icle and affected tire(s)
and rim(s) inspected by a n authorized Audi
dealer. Tires that have been driven in the run­
f lat mode must be rep laced .
A WARNING
-Use of damaged run-flat tires and rims can
cause vehicle damage that can lead to loss
of vehicle control, a crash and serious per­
sonal injury.
- Always have the vehicle and affected
tire(s) and r im(s) inspected by an author­
ized Audi dealer after driving a tire in the
run-flat mode .
- Tires that have been dr iven in the run­
f lat mode must be replaced.

Operating your vehicle
outside the U.S.A. or
Canada
Government regulations in the United States
and Canada require that automobiles meet
specific emission regulations and safety
standards. Therefore, veh icles built for the
U.S.A. and Canada differ from vehicles sold in
other countries .
If you p lan to take your vehicle outside the
continental limits of the United States or Can­
ada, there is the possibility that:
- unleaded fuels for vehicles with cata lytic
converter may not be available;
- fuel may have a considerably lower octane
rating . Improper fuel may cause engine
damage ;
- service may be inadequate due to lack of
proper service facilities, tools or testing
equipment ;
- replacement parts may not be readily availa­
ble.
- Navigation systems for vehicles built for the
U.S.A. and Canada will not necessari ly work
in Europe, and may not work in other coun­
tries outside of North America.

Maintenance
' General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
safety, economy and reliability . For detailed
vehicle maintenance consult your Warranty

Under difficult operating conditions , for ex­
ample at extremely low outside temperatures ,
in very dusty regions, etc., some service work
shou ld be pe rformed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air fi lter.
@ For the sake of the environment
By regu larly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus min imizing adverse
effects on the environment.
