& WARNING (co ntinued )
• Snow chain s are available in different sizes. Always make sure
to follow the instructions provi ded by the snow chain manufac­
turer.
• Wh en driving with snow cha in s never drive fa ster than the
speed permitted for your specific snow chains .
• Always observe local regulations.
0 Note
• Remove snow chains before d riving on roads not cove red w it h
snow to avoid damaging t ires and wearing t he snow chains down
unnecessar ily .
• Snow chains, which come into direct contact wi th the wheel rim,
can scratch or damage it . The refore, make s ure that the snow chai ns
are sui tably covered. Chec k the pos it ion o f the snow cha ins afte r
driving a few yards and correct if necessary . Follow the instructions
from t he snow chain man ufacturer when doing so .
[ i] Tips
• Where snow chains are mandatory on certa in roads, this normally
also app lies to ve hicles wi th A ll W hee l Dr ive.
• If snow chains are installed, the tire p ress ures s houl d not be
sto red in the tire pressure moni to ring system (TPMS) . Otherwise the
system could malfunction ~

Wheel bolts
Wheel bolts must al ways be tight ened to the c orrect
torqu e.
The desig n of whee l bolts is matc he d to the fa ct ory in stalled rims. If
different r ims are fitted, the cor rect wheel bo lts wi th t he r igh t length
and correctly s haped bolt hea ds must be used . Thi s ensures that
Safety first
wheels are fitted securely and that the brake system funct ions
cor rectly .
I n certa in circumstances, yo u may not use wheel bo lts from a
different vehicle -even if it is the same mo del.
& WARNING
Improperly tightened or maintained wheel bolts can be come
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 bolt s can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the th reads in the wheel
hub s. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolt s 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 loo sen and come out when the
vehicle is moving . If the tightening torque is too high , the wheel
bolt s and thread s can be damaged and the wheel can become
loose.
0 Note
T he specified torq ue for the wheel bo lts is 90 ft lb (120 Nm) with a
t o le rance of ± 7,4 ft lb( ± 10 N m). Tor qu e wheel bo lts diagonally.
After cha nging a wheel, the torque must be checked as soon as
pos sible wi th a t orque w rench -prefer ably by an auth oriz e d Aud i
dealer or qualified workshop .•

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Aud i dealer for
more details .
Th e low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation . The numeral represents the ratio of
the tire's sidewall height in relation to its tread width expressed in
percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is 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 pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 252, "Checking t ire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact w ith
potholes, curbs, gullies or ridges on the road, particularly if the tire is
unde rinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle , we recomme nd that you observe the following precau ­
tions:
• Always maintain recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive ca refully on roads with potholes, deep gullies or ridges. The
impact from driving through or over such obstacles can damage your
tires. Impact with a curb may also cause damage to your tires .
• 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 underinflat ion, which could eventually cause tire fa ilure . If
you believe that a tire may have been damaged, replace the tire as
soon as poss ible .
• Th ese tires may wear more quickly than others.
• Please a lso remember that, while these tires deliver responsive
hand ling, they may rid e 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 t ires originally installed on your vehicle are
intended for maximum dry and wet road perfo rmance and handling.
They are not su itable for cold, snowy or icy weather conditions . If you
drive under those circumstances, you should equip yo ur vehicle with
all-season or w inter tires, which offer better traction under those
conditions . We suggest yo u use the recommended snow or all-season
tires specified for your veh icle, or their equivalent .
Refer to =>
page 261 for more detailed information regard ing winter
tires. •
Tire pressure monitoring system

General notes 1
Each tire, including the spare (if prov ided) , shou ld be checked
month ly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or t ire
inf lation pressure label. (If your vehicle has tires of a different size
than the siz e indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper t ire inflation pressure for
those tires.)

& WARNING (continued)
no circumstances should you store the spare wheel or jack and
tools uns ecured in the passenger compartment. Thi s could cause
serious personal injury to passengers in the vehicle in case of a
c ollision.
• The compact spare ti re is for temporary use only and is so
marked on the sidewalls .
• Do not d riv e at speeds e xceeding 50 mph (80 km/h ) with the
compact spare wheel mounted . Also rapid acceleration, hard
braking and hard corne ring must be avoided to help prevent loss
of vehicle control.
• Any continuous road use of the compact spare tire may result
in tire failure, los s of vehicle control and injury to vehicle occu ­
pants.
• Do not put a snow chain on your compact spare tire. Due to the
smaller tire size, the chain will not fit properly and can thus
damage your vehicle. You could also lose th e chain, as well as
control of the vehicle .
• If you have a flat front tire in road cond itions which require
snow chains , first remove the undamaged rea r wheel and mount
the compact spare wheel in its place . Then remove the damag ed
front wheel, take the snow chains off it and attach them to the
wheel taken from the rear. Thi s wheel can now be mounted on the
front with its snow chains. Check and adjust tire pressure
promptly.
• Never use two or more compact spare tires at the same time .
0 Note
When using the compact spare wheel, note the following:
• After i nstalling the compact spare w heel, the t ire inflation pres­
sure should be checked and, if necessary, increased to 60 ps i
(4.2
bar). •
The load carry ing capac ity is marked on t he tire sidewalls and
mus t not be excee ded.
• After installing the compact spare wheel, make sure that yo u
remoun t the fla t ti re in its sto rage are a properly.
• The compact spare tire should be properly remo unted in its
st ora ge area as soo n as th e s tand ard road ti re c an be repla ced.
• Beca use the compact spare tire was specif ically des igned for your
veh icle, it must not be use d on any other veh icle . Likew ise, compact
spare wheels from other vehicles m ust not be used on your vehicle.
• Th e compac t spare tire must not be mounted on any other w heels,
nor m ust standard t ires, snow tires, wheel covers or tr im rings be
used w ith the compact spa re wheel.
If suc h use is a ttempted, damage
to these items or othe r vehicle components may occur.
[ i ] Tips
Check the inflation p ress ure o f the compact spare tire (60 psi/4.2
bar) pe riodic ally to kee p t he ti re read y for use. •
