2013 AUDI A5 COUPE wheel bolts

Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
~ Wash the wheels with a sponge or hose
brush every other week.
~ For deep cleaning afterwards, use only a
dedicated
aci d-fr ee cast alloy wheel cleaner.
~ Rub a coat of liqui d wax onto the r ims every
t hr ee month. Be sure to reach and treat a ll
parts of the r im.
To preserve the decorat ive appearance of the
cast alloy whee ls, some special care is neces­
sary. I n add it ion to road d ir t and sa lt, b rake
dust is a lso cor ros ive. If left on for too long,
b rake dus t ca n cause pitting.
Use only specia l
acid-free cleaners formulated
fo r alloy rims. Safe products are available at
your author ized Audi dealer. Never leave the
cleane r on the rims longer than specif ied on
the label. If not rinsed
off promptly, the acid
contained in some cleaners can attack the
threads on the whee l bolts.
Never use abras ive or metal polishing clean­
ing agents.
If the protective coating has been
chipped, e .g. by kicked up road dirt, touch it
up as soon as possib le.

U.S. DOT Ti re Identification Numb er (TIN)
and ti re manuf actur e date
This is the tire's "serial number" . It begins
with the letters "DOT" and indicates that the
tire meets all federal standards. The next two
numbers or letters indicate the plant where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
For example, the numbers 2212 mean that
the tire was produced in the 22nd wee k of
2012. The other n umbers are mar keting co ­
des that may or may not be used by the tire
manufacturer . This information is used to con­
tact consumers if a tire defect requires a re ­
call.
Audi Original tir e
Tires with the identification "AO" or "RO" have
been specia lly matched with your Audi . We
recommend using only these tires because
they meet the highest standards regard ing
safety and driving character istics when used
correctly. Your authorized Audi dealer will
glad ly provide you with more information.

@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
Snow cha ins may be fitted only to the front
whee ls, and o nly to certain tire sizes . Ask your
autho rized Aud i deale r on which tire sizes
snow c ha ins can be used.
The snow chains must have low-prof ile links
and must not be t hicker than 0.53 inch
(13.5 mm) , includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow cha ins on your vehicle
c::> Q) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are ava il­
able from autho riz ed Aud i dealers.
A WARNING
Using the wrong snow chai ns for your vehi­
cle o r insta lling them in co rr ect ly can in­
crease the risk of loss of cont ro l leading to
serious pe rsonal injury.
- Snow chains are available in different
sizes. A lways make sure to follow t he i n­
structions p rov ided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove s now c hain s be fo re dr iv ing o n
roads not covered with snow to avoid
damaging tires and wea ring the snow
chains down unnecessa rily.
- Snow chains, which come into direc t con ­
tact with the whee l rim , can scratch or
damage it . Therefo re, make sure that the
snow chains are s uitably covered. Check

driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this normally also applies to
vehicles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
¢ page 275.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious persona l in­
Jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly 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 tor­
que of the wheel bolts is too low, they
can loosen and come out when the veh i- cle
is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi­
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work­
shop.
Low aspect ratio tires
Your Audi is factory -equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road feel
and handling under a variety of driving condi­
t ions . 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 s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
tional tires have a height/w idth rat io 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 237, 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 potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.
