T he tires and rims are essential
parts of the vehicle's design .
The tires and rims approved by
Audi are specially matched to
the characteristics of the vehi­
cle and can make a major con­
tribution to good road holding and safe handling when in good
condition and properly inflated
c::> ,&. .
We recommend that a ll work
on tires and wheels be per­
formed by an authorized Audi
deale r. They are familiar with
r ecommended p rocedures and
have the necessary special too ls
and spare parts as well as the proper facilities for disposing of
the old ti res.
Autho rized Audi dealers have
the necessary information
about technical requirements
for installing or changing tires
and rims .
Replacing tires and wheels
Tires sho uld be replaced at
least in pairs and not individu­
ally (for example both front
tires or both rear tires togeth­
er).
B e sure to read and heed the in ­
formation to the tire pressure
monitoring system
c::> page 267.
Always buy replacement radial
tires that have the same specifi­
cations as the tires approved
f or your vehicle by Audi. Re­
placeme nt tires m ust always
have the same load rating spec­
ification as the orig inal equip­
ment or approved optional tires
listed in the table
c::> page 244.
Audi-app roved spec ificat io n
tires are specially matched to
your vehicle and its load limits ,
and can contribute to the im -
portant roadholding, driv ing .,.

264 Tire s and wheel s
Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure<=>,& .
The grade C corresponds to a level of perform­
ance which a ll passenger car tires must meet
under the Federa l Motor Veh icle Safety Stand ­
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the m inimum required by law .
A WARNING
The traction grade assigned to this t ire is
based on stra ight-ahead braking traction
tests, and does not include acceleration,
corne ring, hydrop lan ing o r peak traction
character istics .
A WARNING ,.,.____
The temperature grade for this tire is es­
tablished for a tire that is p roperly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
separate ly or in combination, can cause
heat buildup and possible tire fa ilure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F
(7 °C) we recommend changing to winter
tires .
In some heavy snow areas, loca l governments
may require true winter or "snow" tires, those
with very deeply cut tread. These t ires should
only be used in pairs and be installed on all
four wheels. Make sure yo u purchase snow
tires that are the same size and const ruct ion
type as t he other tires on your ve hicle.
If your vehicle is equ ipped with all -wheel
drive*, this will improve t ract ion during w inter
d riving, even wit h the standard tires. Howev­
e r, we strong ly recommend that you always
eq uip a ll four w heels on yo ur vehicle wi th cor­
rectly fitted win ter tires or a ll-season tires,
when winte r road conditions are expected . This also improves the veh
icle's brak ing per ­
formance and reduces stopping distances.
Summe r tires p rovide less gr ip on ice and
snow.
Winter tires (snow tires) must always be fitted on all fou r wheels .
Ask your authorized Audi dealer or qualified
workshop for perm itted
winter tire siz es. Use
o n ly rad ial winter t ires .
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0 .157 inch
(4 mm).
Only drive w ith w inter t ires under winter con ­
ditions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat tire, see notes on spare
wheel
<=>page 257.
Please a lways remember that winter tires may
have a lower speed rating than the tires origi ­
nally installed on your vehicle at the time it
was manufactured. P lease see<=>
page 260,
Speed rating (letter code)
fo r a listing of the
speed rating lette r codes and the max imum
speed at which the tires can be d riven .
The speed rating letter code (<=>
page 242) is
on the side wall of the t ire
c> page 257.
A WARNING ,.___
W inter t ires have maximum speed lim its
that may be lower than yo ur vehicle's max­
i mum speed. Always know the max imum
speed before dr iv ing off. Never dr ive faster
than the speed permitted for yo ur specific
winter tires . This wi ll ca use damage to the
tires leading to an accident and ser ious
personal injury to you and your passen­
gers.
A WARNING
'----
Driving faster than the maximum speed
for which the winter tires on your vehicle were designed can cause t ire failure in­
cluding a blowout and sudden deflation,

loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed.
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10,5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q(D _ For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
Tires and wheels 265
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
([) Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the vehicle.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all-wheel drive.

thro ugh or over such obstacles can damage
your tires. Impact with a curb may a lso
cause damage to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Audi dea ler. Replace a damaged
t ire as soon as possible.
- Inspect yo ur tires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause tire fa ilure . If you be lieve that a
t ire may have been damaged, replace the
t ir e as soo n as possible.
- T hese tires may wear more quickly than oth­
ers .
- Please also remember that, while these tires deliver respons ive handling, they may ride
less comfortably and make more no ise than
othe r cho ices .
Reduced perf ormance in winter /cold
season condition s
All t ires are des igned for certain pu rposes.
The low aspect ratio, ultra hig h pe rformance
tires orig inally installed on your veh icle are in ­
tended for maximum dry and wet road per ­
formance and handling . They are not s uitable
for cold, snowy or icy weather conditions. If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offer better traction under
those cond itions . We suggest you use the rec­
ommended snow or all-season tires specified
fo r your ve hicle, or their equ ivalent.
Refer to¢
page 264 for mo re deta iled infor ­
mat io n regarding winter t ires .
Tire pressure
monitoring system
U) General notes
Each t ire, includ ing the spare (if provided),
should be checked month ly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r o n the vehicle
p lacard or tire inflation pressure label. (If yo ur
Tire s an d wheel s 267
vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in­
flat ion pressure labe l, you sho uld determine
the proper t ire inflation press ure for those
tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
ti res is significant ly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper pressu re. Driving on a sign ifican tly un­
der -infla ted ti re causes the tire to overhea t
and can lead to tire fai lure . Under-inflation al ­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­ er's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to tr igger illuminat ion of t he
TPMS low tire pressu re tellta le.
Your vehicle has also been equipped with a
TPMS malfunction indicator to ind icate when
the system is not operating properly. The
TPMS ma lfunction indicator is combined with
the low t ire pressure telltale . Whe n the sys­
tem detects a malfunction, the telltale will
flash fo r approximate ly one m inute and then
r em ain continuously illum ina ted . Thi s se­
quence will continue upon s ubsequent vehicle
start-ups as long as the malfunction exists .
When the malfunction indicato r is illum inat­
ed, the sys tem may no t be ab le to detec t or
s ignal low tire pressure as in tended . TPMS
malfu nctions may occur for a var iety of rea ­
sons, incl uding the insta llation of rep lace­
ment or a lternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning properly. Always check the TPMS malfunction
telltale after rep laci ng one or more tires or
whee ls on your vehicle to ensu re that the re­
placement o r alternate tires and wheels a llow
the TPMS to con tinue to funct ion p ro perly .

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
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , when towing a trailer
very frequently, etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
(® For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing adverse
effects on the environment.
Important considerations for you and
your vehicle
The increasing use of electronics, sophisticat­
ed fuel injection and emission contro l sys-
tems, and the genera lly increasing technical
liJJ,

M N

complexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, safe ty and e nvir onm en tal con­
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans ­
miss io n pa rts which an owner can perform .
Maintenance, adjustments and repairs usua lly
require special tools, testing devices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­ ranty. The refo re, p roof of servici ng in accord­
ance w ith the maintenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your authori zed Audi dealer or any other
properly equipped and q ualified workshop .
We strong ly urge you to give you r a uthorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
