Tires and wheels -________________ fff'II
& WARNING
Always adjust your driving to the road and traffic condit ions.
Never let the good a cceleration of the winter tires and all-wheel
drive t empt you into tak ing e xtra ri sks. Always rememb er:
• When braking , an all-wheel drive vehicle handle s in the same
way as a front drive vehicl e.
• Drive carefully and reduce your speed on icy and slippery road s,
even winter tires cannot help under black ice condit ions.
c£> For the sake of the environment
Use summer tires when weather co ndit ions permit. They are qu ieter,
do not wea r as qu ickly and r educe fuel consumpt ion. •
Snow chains
Snow c hains m ay be fi tted on ly to the rear w heels, and only to cer tain
tire sizes . Ask your authorized Audi dea ler on wh ich tire sizes snow
c hains can be used .
Th e snow chains must have low-profile links and m ust not be thicker
than 0.53 inch ( 13 .S mm), including the lock .
Remove wheel ce nter covers and trim discs before put ting snow
chains on your vehicle~
0. For safety reasons cover caps must then
be fi tted over t he wheel bolts . T hese a re av ail able fro m auth o rized
Audi dealers.
& WARNING
Using the wrong snow chains for your vehicle or installing them
in correctly can increa se the risk of loss of control leading to
serious personal injury.
Safety first
& WARNING (co ntinued )
• Snow chains are available in different sizes . Always make sure
to follow the instruction s provided by the snow chain manufac
turer.
• When driving with snow cha ins never drive fa ster than the
speed permitted for your specific snow chains .
• Always observe local regulat ions.
0 Note
• Remove snow chains before driving on roads not covered wit h
snow to avoid damaging t ires and wear ing the snow chains down
unnecessar i Ly .
• Snow chains, whi ch come into direc t contac t wi th the w heel rim,
can scratch o r damage it. Therefore, make s ure that the snow chai ns
are sui tably covered. Chec k the pos ition of the snow chains after
dr iv ing a few yards and correct if necessary . Follow the instruct ions
from the snow chain ma nufact urer when do ing so.
• If the Adaptive Air Suspension* should malfunct io n, do not mount
or use snow chai ns because the ve hicle w ill be extreme ly low. If you
do d rive with snow chains on while the vehicle is at this level, the
snow c hains m ight severe ly damage the whee lhouse and other parts
of t he ve hicle .
[ i ] Tips
Whe re snow c ha in s are mandatory on ce rtain roads, t his norm ally

Wheel bolts
Wheel bolts must al ways be tightened to the correct
torque .
The design of wheel bolts is matched to the factory installed rims. If
different r ims a re fitted, the cor rect wheel bolts with the r ig ht leng th
and correctly shaped bolt heads must be used. Th is ensures that
w heels are fitted secure ly and that t he br ake system func tion s
correctly .
In certain circ umstances, you may not use whee l bolts from a
different veh icle -even if it is the same model~
page 370.
&_ WARNING
Improperly tightened or maintained wheel bolts can become
loose causing lo ss of control , a c ollision and seriou s personal
injury .
• Always keep the wheel bol ts and the thread s in the wheel hub s
clean so the wheel bolts can turn easily and be properly t ighten ed .
• Never gr ease or oil the wheel bolt s and the threads in the wh eel
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 .
• Alway s maintain the correct tightening torque for the wheel
bolt s to reduce the risk of a whee l los s. 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 i s too h igh, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The spe cifie d torq ue for the whee l bolts is 120 ft lb (160 Nm) wi th a
tolerance of ± 7,4 ft lb( ± 10 Nm). Torque whee l bolts diagona lly. After changing a wheel, the torq
ue m ust be checked as soo n as
possible wi th a t orqu e w rench -prefer ably by an auth o riz ed Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
h ave bee n thorou ghly teste d and been se lec ted spe cifically fo r yo ur
model for their superb performance, road feel and hand ling u nder a
var iety of dr iving con ditions . Ask your authorized A udi dea le r for
more deta ils.
The low aspect ratio of these t ires is ind icated by a n umera l of
55 or
le ss
in t he tire 's s ize designation . T he numera l rep resents the ratio o f
the tire's sidewall he ight in relat ion to its tread width exp ressed in
pe rcen tage . Co nven tional ti res have a heig ht/w idth r atio o f 60 o r
more.
The performance of low-aspect-ratio tires i s particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pre ssure is regularly checked and maintained. Tire pre s
sures should be checked at least once a month and always before a
long trip~
page 324, "Che cking t ire press ure".
What you can do to avoid tire and rim damage
Low aspe ct ratio tires ca n be damaged more eas ily by imp act wi th
potholes, curbs, gul lies or ridges on the road, part icu lar ly if the tire is
unde rinfl ated.
I n order to minimize the occu rrence of impact damage to the tires of
your vehicle, we recommend that yo u observe the follow ing p recau
tions:
• Always ma inta in recommen ded inflation p ressures. Check your
t ire press ure every 2,000 m iles (3,00 0 km) a nd a dd air i f ne cess ary.
• Drive ca ref ully on roads with potho les, dee p gullies or ridges. The
i m pact from d riving t hrough or over such obsta cles can damage you r
tires. Impact w it h a c urb may also cause damage to your tires . .,_

________________________________________________ T_i_re _ s_ a _ n_d_ w_ h_ e_ e_l_s __ ,n
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• These tires may wear more quickly than others .
• Please also remember that, while these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio, ultra high performance tires originally installed on your vehicle are
intended for maximum dry and wet road performance and handling.
Th ey are not su itable for cold, snowy or icy weather conditions. If you
drive under those circumstances, you should equip your vehicle with
all -season or winter tires, which offer better traction under those
conditions. We suggest you use the recommended snow or all-season
tires specified for your vehicle, or their equiva lent.
Refer to~
page 334 for more detailed i nformat ion regard ing w inter
tires. •
Tire pressure monitoring system
General notes I)
Each tire, including the spare (if prov ided), should be checked
month ly when cold and inflated to the inflation pressure recom
mended by the vehicle manufacturer on the vehicle placard or tire
inf lation pressure label. (If your vehicle has tires of a different size
than the size ind icated o n the vehicle p lacard o r tire inflation pressure
Safety first
label, you should determine the proper tire inflation pressure for
t hose tires.)
As an added safety feature, your vehicle has been equipped with a t ire
pressure monitoring system ( TPMS) that illuminates a low tire pres
s ur e telltale when one or more of your tires is significantly under
inflated. According ly, when the low tire pressure te lltale illuminates,
you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a sign ificantly under- inflated
tire causes the tire to overheat and can lead to tire failure. Unde r
inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper t ire ma inte
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if unde r-inflation has not reached the level to trigge r
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been eq uipped with a TPMS mal function indi
cator to indicate when the system is not operating properly . The
TPM S malfunction indicator is combined with the low tire pressure
telltale . When the system detects a ma lfunct ion, the telltale will
flash for approximately one minute and then remain continuously
illuminated . T his sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indica tor is illum inated, the system may not
be able to detect or signal low tire pressure as intended. TPMS
ma lfunctions may occur fo r a variety of reasons, including the instal
lat ion of replacement or alternate tires or wheels on the veh icle that
prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replac ing one or more tires or wheels on
your vehicle to ensure that the rep lacement or a lternate tires and
wheels allow the TPMS to continue to function properly .•
