208 Clea ning and protec tio n
- Damage or ma lfunction of electrical
components due to water damage or any
other outside influence is not covered by
the Aud i New Vehicle Limited Warranty.
See your Warranty
& Maintenance book­
l et for additional details about your war­
ranty.
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
liqui d wax onto the r ims every
three month . Be sure to reach and treat a ll
parts of the rim.
To preserve the decorat ive appearance of the
cast alloy wheels, some specia l care is neces­
sary. In addit ion to road d irt and sa lt , brake
dust is a lso cor ros ive.
If l eft on for too long,
brake dus t 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 longer 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 ras 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 possible .
.&, WARNING
-Moisture and ice on brakes may affect
braking efficiency¢
page 188. Test the
brakes carefully each time you wash the
vehicle .
- Always read and heed all WARNINGS and
other information
¢ page 202.
Body cavity sealing
The body cavity sealing does not need to be
checked .
All body cav ities which could be affected by
corros ion have been thoroughly protected at
the factory .
This sealing does not require any inspection or additional treatment. If any wax should seep
out of the cavity when the ambient tempera­
ture is high, it can be removed with a plastic scraper and a suitable solvent .
.&, WARNING '"-'--
Solvents can be dangerous .
- Benz ine is flammable and toxic. If you
use benz ine for removing the wax, keep
spa rks, flame and lighted cigarettes
away. Never dump benz ine on the
g round, into open streams or down sew ­
age drains .
- Be s ure to observe all safety and environ­
mental regulations. Follow all instruc­
tions on the container.
- Always read and heed all WARNINGS and
other information ¢
page 202.
Chassis
Have the undercoating checked for damage
from time to time.
The lower body shell of your Aud i is also thor­
oughly p rotected against corros ion.
Any damage to the undercoat ing caused by
road hazards should be repaired promptly .
.&, WARNING
Too much undercoating in the wrong p la­
ces can cause a fire.
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, catalyti c con­
ver ter or heat shields. While driving, the
substance used for undercoating could
overheat and cause a fire.

Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.5 mm), including the lock .
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
~ 0. For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
~ WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control 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 specific snow chains.
- Always observe local regulations.
(D Note
- Remove snow chains before driving 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 wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(j) Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all wheel drive.
Tires and wheels 251
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is ma tched to the
factory inst alled rims. If diffe ren t 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 282 .
&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control , a collision and serious personal 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 vehi­
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.
(I} Note
The specified torque for the wheel bolts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts .,.. •

-Check the tire pressure on the spare imme­
diately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as possible by your authorized Audi dealer or
a qualified workshop.
- With steel and alloy wheel rims , the wheel
bolts are correctly tightened at a torque of
90 ft lbs . (120 Nm).
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing
a tire, they should be replaced before you
check the tightening torque .
- Replace the flat tire with a new one and
