& WARNING
Using the wrong snow chains for your vehicle or in stalling them
incorrectly can increase the risk of loss of control leading to
serious personal injury.
• Snow ch ains are available in different sizes . Always make sure
to follow the instructions provided by the snow chain manufac ­
turer .
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains .
• Always observe local regulations .

Wheel bolts
Wheel bo lts must alw ays be t ig hte ned to the correct
to rq ue .
The design of wheel bo lts is matched to the factory instal led rims. If
d iffere nt rim s are fitted, the corr ect w heel bo lts w it h t he rig ht le ngth
and correctly shaped bolt heads must be used. This ensures that
w he els are fitted securely and that the brake sys tem func tions
correctly.
I n certa in c ircums ta nces, you may not use wheel bo lts from
a
different vehicle -even if it is the same model=> page 368.
& 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 threads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bolts is 9 0 ft lb (120 Nm) with a
to lera nce of± 7,4 ft lb(± 10 Nm). Torque whee l b o lt s d ia go nally.
Af ter changing a wheel, the torque must be checked as soon as .,_

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 hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
more details.
The 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 sidewa ll height in relat ion to its tread width expressed
in percentage. Conventional tires have a height/width ratio of 60 or
more.
The performan ce 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. T ire pres­
s ures should be checked at least once a month and always before a
long trip => page 379,
"Checking tire pressure".
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact with
potho les, curbs, gullies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehicle, we recommend that you observe the following precautions:
• Always ma inta in recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes, deep gu llies 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 underinflation, which could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possib le.
• T hese tires may wear more quickly than others .
• Please also remember that, whi le these tires deliver respons ive
handling, they may ride less comfortably and make more noise than
other choices .
Reduced performance in winter /cold season
conditions
A ll tires are designed for certain purposes. The low aspect ratio,
u ltr a high performance tires originally installed on your vehic le are
intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If
you drive under those circumstances, you should equip your vehic le
with all -season or winter tires , wh ich offer better traction under
those conditions. We suggest you use the recommended snow or all -season tires specified for your vehicle, or their equivalent .
Refer to=>
page 329for more detailed information regarding winter
tires. •

Changing a wheel
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing a wheel.
- After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before

& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flashers on and use other warning
devices to alert other motorists.
• Make sure that passengers wait
in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block

After changing a wheel
A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
- Check the tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
replaced as soon as possible.
[ i] Tips
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Drive at reduced speed until you have the tightening torques
checked .•
