2013 AUDI S4 SEDAN wheel bolts

204 Cleaning and protec tio n
Cast (light) alloy wheels
Cast (light) alloy wheels require special care .
• Wash the whee ls 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
liq uid wax onto the r ims every
t h ree month . Be sure to reach and treat a ll
parts of the rim .
To preserve the decorat ive appearance of the
cast alloy whee ls, some specia l care is neces­
sa ry. In addit ion to road dirt and sa lt, b rake
d ust is a lso corros ive. If left on for too long,
b rake dust can cause pitting.
Use only specia l
acid-free cleaners formulated
for a lloy rims . Safe p roducts are available at
your author ized Audi dealer. Never leave the
cleane r on the rims longe r than specified 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 ab rasive or metal polishing clean­
ing agents. If the protective coating has been
chipped, e .g. by k icked up road dirt, touch it
up as soon as possible.
A WARNING
- Moisture and ice on brakes may affect
braking efficiency ¢
page 187. Test the
brakes carefully each time you wash the
vehicle .
- Always read and heed all WARNINGS and
other information ¢
page 199.
-
Body cavity sealing
The body cavity sealing does no t need to be
checked.
A ll body cavities which co uld be affected by
corrosion have been thoroughly protected at
the factory.
This sealing does not require any inspection or
addit ional treatment . If any wax should seep
out of the cav ity when the ambient tempera- ture is high, it can be removed with a p
lastic
scraper and a suitable solvent.
A WARNING
-Solvents can be dangerous.
- Benzine is flammab le and toxic. If you
use benzine for removing the wax, keep
sparks, flame and lighted cigarettes
away. Never dump benz ine on the
ground, into open streams or down sew­
age drains.
- Be sure to observe all safety and environ­
mental regulat ions . Follow all instruc ­
tions on the container .
- Always read and heed all WARNINGS and
other information ¢

, Chassis
Have the undercoating checked for damage
from time to time.
The lower body shell of your Audi is also thor­
oughly protected against corros ion.
Any damage to the undercoating caused by road hazards should be repaired prompt ly .
A WARNING
Too much undercoating in the wrong p la­
ces can cause a fire.
- Do not app ly additional undercoating or
r u stproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. While driving, the substance used for undercoating could
overheat and cause a fire.

c::> page 241.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inter t ires. This will cause damage to the
tires leading to an accident and serious
personal inj ury 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 tire failure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immed iately .
- Winter tires have maximum speed rat ing
that may be lower than your veh icle'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 whee l
drive tempt you into taking extra r is ks . A l­
ways remember :
- When brak ing , an a ll whee l drive vehicle
hand les in the same way as a front drive
vehicle.
- Drive caref ully and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
{® Fo r the s ake of the en vironment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be f itted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used.
The snow chains must have low-prof ile links
and must not be th icker than 0.53 inch
(13 .5 mm), includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow chains on your vehicle
c::> @ . For safety reasons cover caps must then
be fitted over the wheel bolts . These are avail­
able from autho rized Aud i dealers.
A WARNING
Using the wrong snow chai ns for your veh i­
cle or instal ling them incorrect ly can in­
crease the risk of loss of cont ro l 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 specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before dr iv ing 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 whee l rim, can scratch or
damage it . Therefore, make sure that the
snow chains are s uitably covered. Check
the pos ition of the snow chains after

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 norma lly also applies to
veh icles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit ­
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model
<=> page 274.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop­
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 24 7
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) w ith a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i­
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k­
shop.
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
tions . Ask your authorized Aud i dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s­
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 236, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.
